Your chimney has one job: carry smoke, heat, and combustion gases out of the house without letting fire or water into the structure around it. When it stops doing that well, the signs are usually small before they're expensive. This page explains what chimney professionals actually check, what creosote does, what the inspection levels mean, and when to book — then ENTER SIX matches you with one vetted, insured professional in your area, licensed where required.
"Chimney service" covers several different jobs. Knowing which one you're asking for makes the first call shorter:
Most homeowners start with an inspection — it's the only way to know which of the rest you need. ENTER SIX sends your request to one vetted, insured chimney professional, never a list of companies.
Every wood fire releases unburned gases and particles. When they meet a cooler flue, they condense on the walls as creosote — and creosote burns.
It shows up in roughly three stages: light flaky soot, a hard crunchy layer, and a shiny tarlike glaze that's the hardest to remove and the most dangerous. Buildup speeds up when you burn wet or unseasoned wood, run slow smoldering fires with the air shut down, or vent into an oversized or exterior chimney that never gets warm.
A chimney fire can be loud and obvious, or a slow burn you never hear. Either one can crack the tiles that separate very hot flue gases from the wood framing in your walls. Burn dry, seasoned wood, and have buildup measured rather than guessed at.
The levels come from NFPA 211, the standard most US chimney professionals work to:
Most chimney problems announce themselves before they become structural:
If a carbon monoxide alarm sounds, get everyone outside and call 911 or your gas utility first. Chimney service comes after.
Two parts at the top do most of the work of keeping water out, and both are easy to ignore because you can't see them from the ground.
The crown is the sloped slab of concrete or mortar covering the masonry at the top. It sheds water away from the flue. When it cracks, water gets into the core of the chimney, freezes, expands, and takes the brick apart from the inside out.
The cap is the metal hood over the flue opening. It keeps rain, snow, leaves, birds, and squirrels out, and its screen keeps sparks off your roof. In Seattle and Portland, where a chimney can stay wet for months, a cracked crown or missing cap does damage quietly. In Boise and New Jersey, the freeze-thaw swing does it faster.
Late summer and early fall is the window. Book before the first cold night and you get your pick of appointment times, plus runway to fix whatever the inspection turns up. By November — in Seattle, Portland, Boise, and across New Jersey — schedules tighten, and masonry work that needs dry weather becomes a spring job.
No one can honestly quote a chimney over the phone. What moves the number:
Your professional prices the job after seeing it, and you approve that price before any work begins.
Inspection and sweeping aren't the same thing. An annual inspection is the standard recommendation for any chimney in service, even one you barely use — it's how blockages, water damage, and liner cracks get caught. Sweeping happens when buildup warrants it, which depends on how much you burn, what you burn, and how you run the fire. A professional measures the buildup and tells you; someone who quotes a sweep before looking is guessing.
Yes. Gas appliances produce moisture and acidic condensate that can eat away at clay tile and mortar over time, and the flue can still be blocked by a bird's nest, debris, or a failed cap. There's no creosote to sweep, but the inspection matters just as much — a blocked or damaged flue on a gas appliance is a carbon monoxide problem, not just a draft problem.
It shouldn't be. A professional working properly uses drop cloths, seals the fireplace opening, and runs a HEPA vacuum under negative pressure while sweeping, so the soot goes into the machine instead of your living room. A straightforward inspection and sweep is usually a one-visit, few-hour job. Repairs, crown work, and relining take longer and depend on weather and access.
An independent local professional does the work — ENTER SIX is an advertising and referral service and doesn't perform home services. We match your request to one vetted, insured professional in your area and verify required licenses in the applicable public contractor registry, where available. They give you the price after seeing the job, you approve it before work begins, and you pay the professional directly.
One request. One professional. Never a lead list. You choose when we call.
