Chimney Inspection Greenwich CT

NFPA 211, the national fire code standard for chimneys, calls for an annual inspection on any chimney in regular use, and it defines three levels depending on what's being checked and why. A Level 1 inspection covers the readily accessible parts of the system, the firebox, damper, crown, and the visible flue, and is what most homes need for a routine annual check. A Level 2 inspection goes further, using a camera to scan the full length of the flue interior, and is called for after a change like a new liner, a chimney fire, storm damage, or before a home sale. Greenwich and lower Fairfield County have a lot of older colonial and stone homes with original masonry chimneys, and a fair number of them have never had the flue interior actually scanned, only looked at from the firebox.

What we're looking for changes by what's asked. On a routine visit, that means creosote buildup and its stage, since creosote forms in layers from a light first-degree coating to a thick, glazed third-degree buildup that's genuinely dangerous and much harder to remove. It also means checking the crown for cracking, the cap for damage or corrosion, the flashing where the chimney meets the roof, and the liner for cracked tiles or gaps that let heat or gas escape into the surrounding masonry. Homes here often run two flues, one for a fireplace and a separate one venting a furnace or boiler, and each gets checked on its own since wear on one doesn't tell you much about the other.

An inspection is also the point where problems get caught before they turn into an expensive repair. A hairline crown crack, a gap in the flashing, or a liner that's starting to deteriorate is far cheaper to address early than after a full season of freeze-thaw cycles and coastal storms have made it worse. If sweeping hasn't happened in a while, a chimney sweep is often paired with the inspection so creosote is cleared while the technician is already up there. If the inspection does turn up masonry damage, chimney repair is something we handle directly rather than referring you out to a separate mason.

We also inspect ahead of a real estate closing, after a chimney fire, or any time something feels off, a strange smell, smoke backing up into the room, or visible staining near the fireplace. Our chimney service in Greenwich treats the inspection as the starting point for almost everything else we do, since it's the only way to know what a chimney actually needs instead of guessing.
