Q&A on Building Interiors: Leaks, Stains, Damage, RepairsQuestion: Does a Small Ceiling Leak Stain Mean I Have a Big Mold Problem? - Exploring Interior Leak Stains on Ceilings and Walls![]() I am writing because I believe that I have a mold problem that has given (or contributed) to my needing sinus surgery for a fungal infection. I live on the upper west side of NYC in a rent stabilized building that is mostly concrete and was built in the 60's I believe. I've had a leak in my closet on and off for about 5 years. [Photo at left of a closet ceiling leak stain was not provided until later in this discussion - Ed.] I live on the top floor. I believe the leak in the roof is fixed. However, I wouldn't let them scrap and patch my closet until I was sure that the leak was fixed. It's about a 12 inch by 12 inch area. However in my panic, I did a really dumb thing. I used a diluted bleach and I cleaned and scraped the area. I was going to let it dry and re-do the process, but in reading online, it was a bad move. Stupid actually. However, I used a respirator and goggles. So my question is - Can I still send a mold test sample to your lab even though it has been bleached. I don't see any mold but while I was spraying, some brown watery stuff came out (might be because there is also brick I believe in the closet.) I am hoping sending it to a lab would be easier and cheaper to do since I have to take two weeks unpaid off from work to have this surgery. Thank you. I appreciate your time in reading this long email. - L.D. Reply: How to Explore Small Leak Stains for Hidden Damage, Mold, and Repair NeedA competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem. And often an expert look at a stain can quickly identify its probable cause and its significance. (STAIN DIAGNOSIS on BUILDING INTERIORS) That said, here are some things to consider: Bleaching a leak-stained or mold-suspect wall: if you didn't get bleach in your eye, bleaching the stained drywall won't hurt anything, but it's not an effective remedy for mold on drywall or other soft walls. MOLD CLEANUP with BLEACH discusses using bleach I'm not sure that sending in a bleached surface mold sample to a lab will produce a reliable result, especially if you cannot discuss the sample and case with the lab first. We have successfully processed samples of bleached mold on wall surfaces before. But the appearance of bleached mold spores changes and can fool a hasty lab technician. For example the characteristic dark black of Stachybotrys chartarum spores appeared pink in bleached samples we processed. As an interesting aside, in such samples we also can often find viable spores that retain their original properties. That's part of our reasoning that bleaching alone is an ineffective mold remedy for drywall. The right repair is to remove moldy drywall, clean the cavity, find and fix the leak, then repair the drywall. See ACTION GUIDE - WHAT TO DO ABOUT INDOOR MOLD. Do you need a mold expert to test or clean the mold? For a 12-inch moldy area on an interior ceiling or wall made of drywall, unless exploration leads to a larger area, honestly, testing and or hiring a mold company is usually inappropriate - as is any visible mold area under 30 sqft. in total size. See DO IT YOURSELF MOLD CLEANUP. See MOLD EXPERT, WHEN TO HIRE for help in deciding when hiring an expert or using a lab is appropriate. There you'll read that where a mold-sensitive person or people with certain health worries are involved, extra care is needed. That said, because you are mold-sensitive, here are some additional caveats: Even for a small mold cleanup, you may be better off having the cleaning performed by someone else, and certainly you'd want to take normal precautions: protective gear, washing up, don't put a moldy finger in your eye, clean up the dust and debris. When to stop the small mold job cleanup: if in the course of the small moldy area cleanup it is discovered that there is or appears to be an area of moldy material largter than 30 sqft, then the job should stop, be sealed off (use plastic and tape), and you should call a professional for advice and cleaning, as dust containment and similar measures may then be needed. If you can send us photos of the leak area I may be able to make further comment. Small Leak Follow-Up: Guessing at the Extent of Hidden Damage
I can get someone to DIY clean it up (thanks to your webite) But since I tested positive for Aspergillus Fumigatus mold spores, I don't want to have surgery for a fungal infection and then have to get it again and have the surgery. I want to know if I was exposed through my building. So that is why I thought I could send in a sample myself to the lab. I don't want to alarm my building (17 floors) but many people have had leaks for years and if i have something, they most likely have something. With the mold info, maybe some of the seniors will allow someone to come in and inspect. Especially if I can get them to read your website info. The DHCR has been useless in our leak problem. And if I had a positive test and had reason to have someone check our building, it might force the hand of the Rent Stabilization board and the DHCR. It could render our building 'sick' and be forced to render the problem. I know that is more information than you need, but I wanted to be clear on why it was so important to me to test a small area myself. Again, thank you so much for your time in reading this and listening to my problem. I'm send some pictures as requested. It will be in a separate email. Again, you and your website has educated me so much. Comments on Closet Ceiling Leak Stain PhotosWith apologies that I must repeat our earlier warning that a competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem, your photographs (above) of the leak-stained closet ceiling look as if there has been a leak of long standing duration, probably from plumbing or other drainage system above your unit. The deterioration of the drywall (if that's what we're seeing) suggests that even though the visible area of the leak is quite small, less than 3 sq.ft., there is a good chance that water has passed over other areas of the ceiling and perhaps down one or more wall cavities on the interior or hidden side. But we really cannot know the extent of moldy material nor hidden damage that might be present before this area is explored. The drywall in the leak area needs to be removed and the cavity explored and cleaned, until there is a 24" margin of visibly clean materials on the cavity side. If at any step in the procedure that exploration finds what appears to be a large area work stops and a professional is brought in to inspect, make a preliminary cleanup plan, set up containment, perform the necessary demolition and cleaning, and then repair the surfaces. Opening the ceiling for inspection may also make it easier to see the leak cause, the track of water from the leak point, (thus knowing what else was wet) and of course to determine the extent of visibly moldy or damaged material. If the cost for what should be a small handyman cleanup job begins to mushroom to a very large expense, have a mold remediation plan drawn up by someone who has no conflict of interest - no financial connection to the cleaning company, and have that same person perform a clearance inspection (MOLD CLEARANCE: FOLLOWUP STEPS) and test before the wall surfaces are put back. The expense of bringing in a mold test expert or mold remediation expert is, as I said before, not appropriate for small cleanup jobs and certainly not for jobs under 30 square feet of demoliton and/or cleaning. Watch out: don't replace the removed ceiling or other surface coverings before the leak cause is identified and repaired. And don't let some idiot make a huge dusty mess throughout your apartment - that can be risky for both your physical health and your financial health. Questions & Answers regarding this article.
