How to find & cure plastic like odors and smells in buildings: this article discusses common odor sources, including indoor plastic odors or chemical smells observed at some installations of vinyl exterior building siding or in other plastic or vinyl building products such as windows and trim.
We describe common sources of plastic or vinyl type indoor odors and we provide a checklist that can help pinpoint the source of such odors by noting information about the building construction, building materials, HVAC systems, weather, sunlight, temperature, time of day, wind direction, and other clues.
We provide links to articles detailing possible health effects of exposure to indoor VOCs and plastic odors and smells.

A variety of common building products, coatings, and furnishings may exude odors that disturb at least some occupants. Most of these occur in new building products and dissipate fairly rapidly. Other building odors or "house B.O." may be persistent or may be intermittent but unpleasant.
Some of these plastic-like odor sources in buildings can be tricky to track down. Here we list some common building products that may produce chemical or plastic like odors. We provide some suggestions for tracking down these odor sources in buildings, and we offer suggestions for removing or curing these odors.
Siding, window, screen, & other "plastic" odors: We've investigated a number of reports of strange odors in residential buildings that were ultimately traced to vinyl or plastic which was outgassing. We've observed this phenomenon with vinyl siding, plastic or vinyl window or door screens, and plastic or vinyl windows.
A key diagnostic step in finding odor source was the observation that the odors were strongest when the material under investigation was exposed to sunlight or other sources of heat. [This article is under development, September 2007, and we welcome content suggestions or questions].
We offer below a list of clues, focused on common sources of plastic-like odors, that any home owner, home inspector, or other investigator can follow in seeking to pinpoint the source of an annoying or obnoxious odor in buildings. Readers are asked to contact us to suggest additions or corrections to this list.
Often people's perception of odors varies with time and exposure or with a number of other site factors that make it hard to track down just where a smell is coming from. But if we think carefully about when, and under what conditions we notice odors, often that information is instrumental in tracking down an odor to its source and thus in helping us decide if an odor refers to a potentially dangerous or unhealthy condition.
This list is in simple alphabetic order, not in order of probable cause, importance, or health risk, all of which can vary widely.
The jury may be out on this question. Plastics are used in an enormous range of building materials and consumer products, and plastics vary widely in their properties, chemical composition, tendency to give off gases, smells, odors, and in possible health concern.
One of the plastics that has received a lot of study are those using vinyl chloride. This product might be present in some common building products such as vinyl siding and vinyl windows or screens. The US EPA has classified vinyl chloride as a Group A, human carcinogen.
For details see PLASTIC or VINYL ODOR EXPOSURE - we have moved the plastic odor or burned plastic exposure discussion there. That article discusses PVC exposure and also more
Watch out: Vinyl chloride might be present in gas form as a colorless, flammable gas with a faintly sweet odor at levels of about 3000 ppm (the odor detection threshold). We provide the US EPA health report on vinyl chloride
You can start tracking down the cause or source of an odor in one or more of several ways:
Chemical Odor / Solvent Odor Complaint "Solved" 12/09/2013 - Vinyl Siding, Trim, Windows Odor on Attached Outdoor Covered Porch or "Florida Room" or "Lanai"
I have very good news... finally! :) We continued to leave the windows open during the first 3 weeks in November. The odor still lingered, but less so because of the fresh air exchange.
So, feeling somewhat confident that it had dissipated sufficiently to allow a potential buyer to come in, we put the mattresses back in and started to put house back together for sale.
Even so, I was still a bit apprehensive that the odor would return as soon as we closed it up.
As I worked inside the house, my husband tackled the lanai outside, which has vinyl windows, screens and an unfinished concrete floor.
He used a heavy mixture of clorox on the concrete floor and the house siding to remove any mildew that had built up during the summer.
Incredibly, the solvent odor actually seemed to have disappeared when he was done! We gave it the closed house test for about an hour and it never built up before we left. Any other time, the odor would have been heavy within 10 minutes.
It really appears that the odor had absorbed into the concrete floor in the lanai and was somehow seeping into the house. When I got home that night, I googled "concrete absorbs solvent odors," to see if that was possible.
It actually pulled up your site where you note that it definitely can pick up chemical odors.
[See CONCRETE DUST & ODORS]
I'm not sure if I read that before, but if I did I guess it didn't strike me as a possibility because I was so focused on the inside where I used the polish. Your site is awesome and has so much useful information
I was in shock... lol, but not quite sure whether to trust that it was really gone. We went back to the house the next day to see if it was still clear and it was. This was very fortunate because someone requested to see the house the very next day. The people came in, there was no smell and they bought the house... it was that fast... :) That was about two weeks ago, and we close on Dec. 20th.
I truly believe the odor had permeated the concrete and was seeping into the house all this time. And we had actually put off washing down the lanai all summer so we could work on the odor first... go figure! I have attached some pictures of the house so you can now see what we were dealing with.
I appreciate your guidance and assistance during the past few months. I am so relieved that we can finally put this nightmare to rest. P.O.D 12/09/2013
I am so happy to hear this odor problem has been put to bed. And thanks for the helpful photos. Just to be sure I understand correctly, "Lanai" as you use it refers to the attached porch along one side of your home, right? A couple of questions remain about why the odor is gone and what one might expect in the future.
1. I have had many reports of odors traced to vinyl products - plastic trim, siding, even window screens. Is it possible that the odor cure is actually because of lower temperatures or closing windows between the house and the actual odor source: the outside vinyl?
See VINYL SIDING or WINDOW PLASTIC ODORS for details.
2. Can we figure out why we didn't figure out why the odor was coming from outdoors? - Ed.
... the vinyl siding is a very good possibility also. There is one wall of vinyl siding on the house inside the porch. The screens in the porch are fiberglass and the windows are vinyl. The vinyl siding was washed down with Clorox and water at the same time as the concrete floor when the smell dissipated. My husband did not spray the vinyl windows and screens with Clorox.
Something I don't think I ever mentioned, and is probably an important clue, I used to smell the odor from down the street as we were driving up to the house, whether the vinyl windows in the porch were open or closed. My husband always thought I was imagining it 'cause he couldn't smell it. It's possible it was coming from all the vinyl in the porch. The odor was very heavy inside the porch whenever we walked in.
Inside the house always smelled whether the windows in the house or the porch were open or closed. The concrete floor does not extend under the house, it is just dirt under there. But it must have been seeping into the house somehow. I believe that opening the windows and airing out the house helped over time, but it did not go away until [we] used the Clorox, at which time it virtually disappeared. - P.O.D. 12/9/2013

Frequently Asked Questions (FAQs)
Question: Trace down [chemical plastic] odors from roof on hot summer days
I had a new roof and gutter system installed a year and a half ago. Most of the roof is asphalt single and a section of the roof is torch on. On hot summer days in the evening when the weather cools down a tar type odor appears in the front of the house. This is where most of the torch on resides.
A new gutter system was also installed at the same time in that same area - it is u-shaped and the corners are sealed with what appears to be a white caulking. This odor has been ongoing since the roof/gutter system was installed and wasn't present before the installation. No one can figure out what this is happening. Any ideas? - Carmine M.
Carmine we wouldn't expect a torch-down roof system to smell like plastic but you might indeed smell bituminous product VOC outgassing from flashings, flashing cement, or the runout or even the bituminous material itself, such as modified bitumen roofing material.
If the odor is plastic-like, I wonder if you've installed vinyl or plastic gutters and leaders?
If the odor is from roofing materials themselves (other than plastic roofing, that is) the outgassing should diminish as the roof system cures in sun over the summer.
If the odor is coming from plastic or vinyl building materials, sometimes those sources can be quite long lasting.
Question: Mysterious plastic related odor when sun hits side of home, headaches, nausea
We are trying to sort out a mysterious odor that we think is "plastic related", but not sure. A strong industrial-plastic like smell only
Localized to one room with interior wall about 18 ft from exterior wall. No where else in house. We think it might be window shades, but hard to believe as odor seems to disappear when blinds are up (recent revelation). We had oil tank removed nearby room about 24 months w/professional contractor with negative soil samples. No oil smell detected ever. Also, localized mold remediation project adjacent room and professionally cleaned up. Need some help?? - Tom
Reply: things to check
Question: Comment on wet plastic odors
Everyone is worried about the smell of the windows in the sun, but they should also be concerned about what vinyl windows smell like when it is damp: you shower, run your stove, etc. Plastic smells when it is wet!! I have double glazed vinyl windows that were installed in a 1950's walk up (in the past 5 years before I moved in).
Everything in this apartment is old - the outside is 1950's stucco (not painted for years), the inside is lathe & plaster (painted with no VOC paint). The floors are the original strip oak floors. We have only wood furniture, cotton futon couch, a 40 year old stove, and a very expensive (not smelly) small fridge that we located well away from the windows.
And yet the B.O. smell coming from these windows fills up the apartment, due to any MOISTURE that accumulates on them, even in the summer. It is especially bad right now since it is in the minus temps, ie. when you wake up there is moisture all over the windows. As soon as you wipe off the moisture, run a dehumidifier, open the window, and pump up the heat - the smell goes away.
Everyone else in our building uses excessive amounts of cheap perfume to cover this up. But I think people should be aware before installing that this could happen to you. Everyone who has visited our apt has commented on it. And ironically enough, these windows don't smell in hot summer (but then again we don't get direct sunlight on them). They are great windows for keeping clean, and blocking out sound. But yes, they are smelly, 24-7. - Molly
Thanks for the comment, Molly. We have not had reports nor tracked down plastic odors to wet conditions. I'd look carefully to be sure there are not other water or leak related odor sources including some molds that can produce odd smells in buildings.
Question: Metallic odor from window screens - what is that odor?
I moved into an apartment and removed the window screens for cleaning, which I did with dish soap and warm water in the tub. Afterwards, however, they emitted a metallic odor, without stop. I tried encasing them in huge plastic bags to contain the smell, with limited success. What on earth is this smell? - Mark W. Sherman 12/12/2011
P.S. The screens themselves are not metallic -- the material is more loose or flexible to the touch than that.
Question: what is the remedy for chemical odors from HVAC ducts
what is the remedy for ducts that emit a strong chemical odor when the heat first comes on? Also notice it when coming in from outside even after it's been on awhile. Or maybe it's the blown-in cellulose insulation? - Susan 12/23/11
Susan: re "odors when heat first comes on" there are several possible explanations, including flue gases that leak out of a draft regulator before a good draft is established, leaks into the ductwork that produce odors that later are diluted by circulating air, or some other source.
Question: vinyl replacement windows smell musty at their seams, especially in sunlight
Last October (2010) we had replacement windows put in. They are stained inside and vinyl outside. If you put your nose to the the seam of the molding on the sides of the windows you can smell a musty/moldy(?) smell. We had no problem prior to this.
The odd thing is that when the sun is hitting the two affected windows (South side of the house) you can sometimes smell it as soon as you walk into the room. When the sun is not as strong (winter/cloudy, etc.) you have to put your nose to the seam to smell it. I have taken off the outlet covers and smelled there figuring if there were mold in the wall I would smell it - just dusty smell like all other house outlets (house built in 62). There are no other signs of mold.
Since the smell strengthens and alleviates (I don't think mold would do that?), It is the south side of the house, and that it started right after the new windows were put in I thought it was associated with that. Have you heard of this with windows. I also suspected the caulk? We removed the molding on one window, caulked, and replaced it and that did cut down on some of the smell.
The other weird thing is that in the summer our room smells worse than my child's and in the winter his smell worse than ours (different ways the sun is shining?). I appreciate any help you can give me. I am wondering if my scenario seems correct and how long until you think the smell will go away. I don't like my son breathing this. - Mel 12/30/12
Indeed there is ample empirical evidence (field reports) that some formulations of vinyl building products emit a plastic odor (possibly vinyl chloride) especially when heated, for example by sunlight.
In our experience the odors usually diminish over time but to those who are sensitive to plastic smells, the odors may not completely disappear.
Watch out: We don't know the chemical composition of the odors you describe, but to be on the safe side, I would NOT have a child sleeping in a room with noticeable plastic odors - wait for them to dissipate. Take a look at the health and exposure information described in the articles beginning at VINYL CHLORIDE HEALTH INFO (article links listed at the "More Reading" links at the bottom of this article ).
Question: Metallic smell in new apartment kitchen in old building - fresh paint? Sun exposure?
We noticed in the fall a distinctly "metallic" smell in our new apartment, specifically the kitchen. This is an old building but the apartment was painted and new flooring installed before we moved in. There were some plumbing issues that we attributed to the smell, as it went away after the plumbing was fixed. However, we are now thinking the plumbing had nothing to do with it and it was just timing.
We had no smell ALL winter, but now it is back on warmer days (above 15 degrees C) and if the sun is out. It is only in our kitchen, which gets the sunlight throughout the day. I have checked all appliances and the exhaust fan, as well as the sink, and cannot pinpoint the smell to anything other than that room. I'm beginning to think it is related to sun/temp. We have blinds that are always up, and windows that are less than 5 years old.
It is a brick building. I have no idea what it could be but it is a terrible smell, and worse - the landlords believe it is our fault and are nagging us to clean it up. Our apartment is clean, i have scrubbed every possible surface in an attempt to get rid of the odor. It is not something we are causing, it must be related to the building somehow. Help! - Jamie 4/14/2012
Question: smell from plastic bags?
We have a constant chemical smell in our home. It is really noticeable when I leave the house, the smell is on my hair and clothing. It seems to attach it self strongly to plastic bags. We live on a golf course, could tat have something to do with it? - Jules 6/3/12
Four months ago, a vinyl floor covering was installed in my computer room and bedroom. IN those two rooms, the smell is very plastic chemical smelling. Not everyone can smell it but I can.. When there is heat in those two rooms, the smell intensifies. My throat is constantly feeling as though it is burning, my lips, my tongue, the membranes of my nose burn and are so dry. my chest feels weighted down. I have washed the floor with every imaginable solution that has been suggested of found on internet. I have air purifiers running, the one in the computer room has a 3 light indicator,states the degree of odor present, when there is an odour present. Short of removing the flooring I don't know what to do.

Question: Plastic odor from PVC deck in sunlight drives us crazy - will the odor go away
We had a cellular PVC deck installed about 6 weeks ago. I can't believe how much of an odor it has when it is in the sun. I can smell it inside the house if the windows are open and it is driving me crazy. As time goes on will this go away? I'm so disappointed. I did a lot of research and didn't come across anything about this in my research and still can't. Any suggestions? - Beth 7/29/12
Beth, sorry to hear about the PVC deck smell complaint - it's not one we've heard reported here before.
Usually but not always, plastic odors dissipate with time, heat, sun exposure.
If you can find out for us the product name and its manufacturer we'll do some further research.
Thank you for your response. It is Timber Tech XLM series. One of their reps told me over the phone that the smell should improve with time but could possibly be detected faintly when warm out--always. I did a lot of reading before choosing this deck material and it seems that the trend now is moving from composite to all PVC or capstock (composite--capped with a PVC layer).
I haven't read a thing anywhere about complaints of the odor--just surprises me as it is quite strong. I don't notice anything when it is not being heated up by the sun, so I hope that with time it will improve. I have read that sun speeds up the off gassing process. I guess I just wonder how long this might take and if it will eventually lose the smell completely.
Beth thanks for the follow-up. The information will help other readers, and we must appreciate the candor and honesty of the Timber Tech rep. I've got no experience with this particular odor problem, so we'll indeed want to hear how much the odor complaint diminishes over time.
In our experience, for people who are sensitive to odors, the smell may never go away completely.
Also if the product accepts a sealant or stain (which themselves will have some odors) you may have some success by coating all surfaces.
Question: window screens smell when the sun hits them
I have a problem with my window screens smelling when the sun hits them - how can I remedy this? Is there a non toxic screen material that I can re - line the screens with? Thanks! - Jessica 9/7/2012
Jessica, you can try replacing the plastic or fiberglass screens with a metal screen material; both galvanized wire and copper wire are available.
Question: severe dizziness & vomiting reported following exposure to plastic / vinyl odor
I have been working hard for long hours outside my aunt's house in New Jersey. Friday Aug. 3 I woke up after a long day of work Thursday. I woke up at 7AM in a 9' x 18' porch of vinyl windows to a sunny morning but a strong plastic odor. Throughout the house my aunt's windows smell of plastic.
I was dizzy and began vomiting and by 8AM I had been transported by ambulance to Overlook Hospital. My body temperature was at 94 but it had been a clear night and the outdoor temp. had dropped and I slept next to an open window with a slow ceiling fan near me but the doctor has asked about carbon monoxide, a furnace pipe, and at that hour and day only a properly venting hot water heater would have been running. I'll check the hospital's blood tests for vinyl chloride other plastic contaminants. Thank you very much. - R. Craig 9/14/2012

Question: how to get rid of lingering fumes & odors from vinyl sheet flooring
I am at a loss as to how to remedy a residential indoor air quality issue. Three months ago, we purchased a house built in 2000, and replaced 1000 sq ft of vinyl sheet flooring with porcelain tile. While removing the sheet vinyl from the concrete floor, an extremely strong chemical odor was continuously emitted. It was several weeks (and the house was closed up) before the adhesive glue was “scraped off” and porcelain tile was laid.
No solvents or water were used to remove the adhesive and the floors were not grinded. Thus, the floors were scraped relatively smooth, but much of the adhesive was still embedded in the concrete when the thinset was spread and the tile put down and grouted. It has now been six weeks since the tile work for the entire house (2100 sf) has been completed. Although somewhat lessened, the odor (from the adhesive glue?) that was present when the vinyl was initially removed is still very noticeable, and is strong enough to cause difficulty breathing.
This surprised me because I was told the tile would seal any odors from the concrete. I don't know the specific compounds in the vinyl glue adhesive made in 2000 (ie how much formaldehyde, etc), how long it might take to off gas, and whether the drywall has absorbed the fumes during the time the vinyl/adhesive was off gassing. (We did paint the walls with zero VOC Benjamin Moore /Sherwin Williams paint after the tile work was completed). In the meantime, we have been opening up the house everyday for 4-5 hours, which helps until a day goes by when the house is closed up.
Then the odor is as strong as ever. We have thus far been unable to occupy the house. Can you provide any direction/suggestions? Thank you in advance for your help. - J.B. 12/15/12
A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem with odors, such as another apparent odor source or pathway, or something that is unfamiliar to building occupants but that may be useful. That said, here are some things to consider - keeping in mind that from no onsite inspection the following is speculation in an effort to be helpful:
In my experience, and similar to your own expectation, porcelain tile and grout, although not 100% impervious to gases and odors, are nearly-so and so would not be expected to pass much odors from prior vinyl flooring tile mastic up through the new floor covering into the room.
Therefore I suspect that there is another odor source. Since you recognize the odor in the area as the same as that emitted when you were removing the old vinyl floor covering, I speculate that VOCs from that procedure may have penetrated other building materials and surfaces, such as drywall, ceiling tiles, &c. that in turn re-emit those gases slowly back into the room.
I have found other examples of lingering odors from building materials that appear intact but that have been either chemically changed or have absorbed gases from an original source (such as following inappropriate use of ozone in buildings)
I am not confident that having coated the walls with the paint you describe would necessarily serve as an odor sealant;
You do not mention what is on the room's ceiling, another possible odor reservoir, nor any furnishings, curtains, etc. that may have been affected by the original odors you describe.
I think that opening and ventilating the building helps, so would turning up the heat and using fans to exhaust heated air - wasting energy for a while but perhaps speeding the odor reduction.
But before spending on any more heroic or extreme attacks on this odor problem why don't you try our odor track-down smell patch test procedure (SMELL PATCH TEST to FIND ODOR SOURCE) to see if you can narrow down an odor source to walls, ceilings, furnishings. That might in turn suggest further steps. For example there are special odor-sealing paints and coatings used to paint building framing or walls following a fire, to control post-fire smoke and burn odors. Those coatings in turn can be re-coated with the desired surface finish paint
Question: vinyl siding plastic odors when neighbor uses barbecue
I have a question after viewing your website. I live in a 4th floor condo and keep getting a burning plastic smell in my master bedroom. It smells awful and usually forces me from the room for hours (it's also my home office). On the other side of my bedroom wall is the balcony of the neighboring suite. That balcony is somewhat "recessed" in that my bedroom actually juts out from the building another 20 or so feet (eg like an "L" with the balcony in the corner). Also, there are NO windows along the entire length of wall adjoining this other suite/balcony.
After 6 months of trying to eliminate all other possible sources, I now believe the smell is coming from the barbeque on the balcony of my neighbor one floor down. The last two times it happened (before tonight), I went down and they confirmed they were barbequing. It happened again tonight but I called the fire department instead so I could confirm that this is not something that should be happening (and a possible health/fire hazard). Two of the firemen said they smelled something as soon as they entered the room. One said it was like a burning plastic smell. But they couldn't identify where the smell was coming from and when I said I was sure it was the barbeque one floor below they basically told me that was impossible.
My question is this - if my neighbor is barbequing on their balcony and the barbeque is positioned too close to the vinyl siding, would it be possible for me to smell melting siding inside?
Thanks for any assistance you can provide (or anyone else you can refer me to - C.P. 8/26/2013
Reply: vinyl siding offgassing & other hazards
A competent onsite inspection by an expert usually finds additional clues that would permit a more accurate, complete, and authoritative answer than we can give by email alone. That said I offer these comments:
Vinyl siding, when heated can give off a distinct plastic odor.
Using a cooking or other heating device close (probably less than 36") to vinyl siding can cause it to deform, melt, and possibly catch fire. Also there might be hazards associated with offgassing of heated vinyl. (See VINYL CHLORIDE HEALTH INFO and also PLASTIC or VINYL ODOR EXPOSURE)
If the neighbor you describe is using a barbecue too close to vinyl siding on e would probably see deformed siding there. Keep in mind that sunlight or other heat sources can also cause vinyl odors and that similar odors can be emitted from other vinyls or plastics on buildings such as windows or screens. Correlating the occurrence of the odor to events (cooking, sunlight, other events) can be key in diagnosis of the odor source.
Watch out: plastic odors can also be traced to overheating electrical components, wiring, devices, and thus there could be a risk of an electrical fire where such odors are reported. Be sure that anyone investigating the odor complaint you describe considers this and other fire or electrical hazards too.
Question: how can I find someone to diagnose chemical smells in my Florida home?
Who can I call to help me find a chemical must smell in Sarasota FL? - D.W. 1/15/2014
Depending on the nature of the odor and its possible sources, you might find success with a home inspector who is familiar with odor tracking and indoor environmental issues - the advantage of a broad-scope-experienced inspector is that s/he may recognize conditions and building air movement, mechanical problem issues etc. that an industrial hygienist, lacking building science expertise, may miss. On the other hand, hygienists and other indoor air quality or indoor environmental experts have expertise in chemical contaminants and testing.
Directories of such experts at InspectApedia are found beginning at
Also, the more you can inform yourself about good procedures for tracking down odor sources the better you can judge the experience, competence, and approach of someone you are hiring.
Question: Plastic or chemical odors: awful odor coming from a new sliding screen door; washed, hosed down, odors continue; chemical smells only when the windows are open?
Help! Just installed a new screen sliding door and the smell is awful! Sprayed it with Simple Green and hosed it down and the "plastic" odor is still not tolerable. Any suggestions?We just installed a new plastic/vinyl screen door and the smell from it is unbearable. We tried spraying it with Simple Green but it didn't help and the smell is overpowering now. What can we do to get rid of this stink other than returning the door? - Ruth 10/24/11 [paraphrased - Ed.]
New construction home (1yr), has a gas like/chemical smell that collects in certain areas of the house only when the windows are open ??? Pretty sure it's not natural gas. When we close windows it goes away.
There is a very strong smell that comes from the corner of our sunroom as soon as it warms up. I think it is stronger when it rains. It's never there during winter. It is so strong you can smell it in the living room. My husband took off the siding and found no mold. I think it smells kinda like mold though. It is so strong it gives me a headache. How can I find out what it is and how to get rid of it? - Jennifer 3/27/12
Reply: check for plastic window or screen odors when some products are heated by sunlight
Ruth & Jason & Jennifer
Some plastic windows or window or door screens can exude a chemical odor, particularly when heated by the sun. You can often track down this chemical-like odor by observing that odors are strongest on the sunlit side of the home and during time when sun is cooking those surfaces.
Some plastic and vinyl building products including windows, doors, and some sidings and trim, outgas a plastic-like odor, especially when new, and in some cases even when not new. But most of these odors dissipate pretty quickly over just a few weeks, and faster if the item, such as your new screen door are exposed to warmth of sunlight.
Question: Smell coming from aluminium window of a newly built home
I have searched your website and can't come up with a solution to an Odor problem we are experiencing in the main bedroom of our newly built home.
The Odor is coming from the aluminium window and seems to be worse in the morning when the sun hits it. We do not have rubber backing curtains that could be the cause. It smells a little like a strong urine smell and when I did the sniff test all around the window, it seems to be the rubber strips/seals that have the Odor, and the sun is making it come out into the whole room and just outside the door. I checked outside and it's not coming from there. It's a new window in a new house and it's the only one with this problem. I suffer asthma/allergies and this smell in my room is making me worse. I am concerned that it is a toxic gas or something coming from the rubber but how will I know if this is the case?
Can you please help at all? What can I do about this problem?
Thankyou! - C.C. 12/2/2014
