Chimney inspection procedures for the building interior: this article describes procedures for inspecting the condition of chimneys and flues from inside of a building. We begin in the building attic (or on the building's highest floor) and continue downwards through the building with text and photographs describing chimney damage or chimney hazards for which the building owner, inspector, or service technician should be alert. Green links show where you are. © Copyright 2013 InspectAPedia.com, All Rights Reserved. Author Daniel Friedman. Inspecting Chimneys from Inside a Building AtticInterior basement and attic inspections will reveal corrosion at the cleanout door, connector problems and flashing leaks. And close inspection of chimney surfaces or walls covering chimneys will often disclose evidence of dangerous chimney conditions such as holes, gaps, and cracks in the chimney structure. Other chimney defects & hazards visible from inside the building are found at Attic Chimney Inspection and at CHIMNEY CLEANOUT DOORS.
Holes in Masonry Chimneys - Missing Bricks
Missing chimney bricks: this photo shows a homeowner "repair" involving putting aluminum sheet metal over a hole in their chimney to make it "safe" - removing the metal disclosed a nice hole where bricks were missing. We asked the homeowner where s/he thought those bricks had gone? This was a very unsafe chimney. The second photo shows the chimney hole with the sheet metal removed. The bricks had fallen down and blocked this flue, creating a potentially fatal carbon monoxide (CO Gas) hazard which was first noticed by the homeowners as a basement water problem - water was condensing and running down basement walls. The topic of how to spot unsafe chimneys and other chimney defects from indoor clues continues at Attic Chimney Inspection and at CHIMNEY CLEANOUT DOORS. Frequently Asked Questions (FAQs)...
