When people call us for a chimney inspection, the most common question isn't "how much" — it's "what are you even looking at up there?" That's a fair question, and a good chimney company should be able to answer it in plain English. This page walks you through the checklist we work from, top to bottom, so you know what a complete inspection includes before anyone climbs on your roof.
Florida adds its own wrinkles. We don't deal with snow or freeze-thaw cracking down here, but we deal with relentless humidity, salt air near the coasts, sideways rain, and the kind of tropical storms that test every seam and seal on a chimney. A lot of the problems we find are moisture problems in disguise, so this checklist leans heavily on the parts that keep water out.
The Exterior: Crown, Cap, and Flashing
The outside of the chimney is where Florida weather does most of its damage, so it's where a good inspection starts. These three parts — crown, cap, and flashing — are your chimney's raincoat. When one fails, water finds its way into places it was never meant to go, and the repairs only get bigger from there.
We're looking for anything that lets moisture in or lets the structure shift. Small cracks and gaps matter here, because a hairline opening that's harmless in a dry climate becomes a steady leak during a Florida summer downpour.
- Crown: the sloped concrete or mortar surface at the very top. We check for cracks, crumbling, and whether it actually sheds water away from the flue instead of pooling.
- Cap: the cover over the flue opening. We confirm it's present, secure, and has intact mesh to keep out rain, debris, and the birds and critters that love an open flue.
- Flashing: the metal that seals the joint where the chimney meets the roof. This is a leading source of ceiling stains, so we look for lifting, gaps, corrosion, and tired sealant.
- Masonry and exterior: spalling brick, open mortar joints, lean or settlement, and salt-air corrosion on any metal components near the coast.
Inside the Flue: The Liner and the Passageway
The flue is the inner channel that carries smoke, heat, and combustion gases up and out. Its condition is a safety matter, not just a maintenance one — a compromised liner can let heat or gases reach parts of your home they shouldn't.
From below and, where access allows, from the top, we check the liner's condition and the passageway's clearance. We're watching for buildup, blockages, and any breakdown in the surface that lines the flue.
- Creosote and soot buildup, and whether the amount calls for a cleaning before the next use.
- Blockages: nests, leaves, fallen debris, or a previous cap failure that let the outdoors in.
- Liner condition: cracks, gaps, deterioration, or sections that have shifted or are missing.
- Clearance and draft: whether the passageway is clear enough to vent properly and draw smoke up instead of back into the room.
The Firebox and Damper: Where the Fire Lives
The firebox is the chamber where you build the fire, and the damper is the movable plate that opens to let smoke out and closes to seal the chimney when it's not in use. Both take direct heat and direct wear, so they get a close look.
Down here we're checking for heat damage and for parts that no longer move or seal the way they should. A damper that won't close all the way is also an energy issue in Florida — it lets your conditioned air slip straight up the chimney.
- Firebox walls and floor: cracked or missing firebrick, gaps in the mortar joints, and signs of overheating.
- Damper operation: does it open fully, close fully, and seal when shut?
- The smoke chamber and shelf above the firebox: buildup and any obstruction that hurts draft.
- Hearth and surrounding clearances: anything combustible too close to the opening.
NFPA Inspection Levels 1, 2, and 3, in Plain English
You'll see chimney inspections described as Level 1, 2, or 3. These come from NFPA 211, the national standard for chimneys and fireplaces. The level isn't about how good the inspection is — it's about how deep it needs to go for your particular situation. Here's the plain version.
Most homeowners who use their fireplace normally and haven't changed anything need a Level 1. The higher levels exist for when something has changed, something looks wrong, or normal access isn't enough to see the whole picture.
- Level 1 — the routine check. For a chimney in continued service with no changes. We examine the readily accessible parts inside and out: the items on this checklist that we can reach without special tools or taking anything apart. This is the right call for regular annual upkeep.
- Level 2 — the deeper look. Required when something has changed or a closer view is warranted: a home sale, a new heating appliance or fuel type, a recent storm, a nearby lightning strike, a chimney fire, or anything a Level 1 turns up. It includes everything in Level 1 plus accessible attics, crawl spaces, and basements, and a closer interior look at the full length of the flue.
- Level 3 — the invasive look. Reserved for when a serious hazard is suspected and the only way to confirm it is to open or remove part of the structure (such as a chase cover or an interior wall section). It's not routine, and a good inspector recommends it only when the evidence points there.
When to Schedule One — and What to Watch For
A yearly inspection is the simple, honest answer for any home with a working fireplace, even one you rarely light. In Florida, we'd also add: after any major storm season, since wind and driving rain are hard on caps, crowns, and flashing.
Beyond the calendar, a few signs are worth a call sooner rather than later. None of these mean disaster, but they're worth getting eyes on before you light the next fire.
- Water stains on the ceiling or wall near the chimney, or a damp, musty smell inside the firebox after rain.
- Smoke pushing back into the room, or a fire that's hard to get drawing.
- White staining (efflorescence), flaking brick, or crumbling mortar on the exterior.
- A damper that sticks, won't seal, or rattles, and any debris falling into the firebox.
- Buying or selling a home with a fireplace — that's a textbook reason for a Level 2.
