It tells you whether the chimney needs cleaning, repair or nothing at all. Afterward you keep the photographs and get a plain explanation that sorts the findings into urgent, can-wait and not-needed. If repair is called for, the scope and price come in writing, and nothing begins until you approve them.
Reasons to book an inspection
The yearly check
The EPA’s wood-burning guidance, echoing fire officials, calls for a professional inspection of the stove or fireplace, chimney and vent each year. A chimney you rarely use still weathers, and nesting birds don’t care whether you light a fire.
Buying or selling a home
A general home inspection may not look much past the firebox and what’s visible from the ground. A dedicated chimney inspection gives buyer and seller a fuller picture.
After a chimney fire, or signs of one
A slow chimney fire can burn without anyone noticing. The evidence the Chimney Safety Institute of America (CSIA) tells homeowners to look for includes broken or collapsed flue tiles, tiles with big chunks gone, and flakes of creosote on the roof or in the yard.
Before relining or changing appliances
A new liner, an insert, or a different stove or furnace all depend on the chimney being suited to it. In Seattle, the city’s residential code calls for masonry chimneys to be lined, and the liner has to suit whatever appliance is connected.
After a leak
Rust stains, dripping or standing water, and bent or damaged flashing are the warning signs CSIA gives for water getting into a chimney. An inspection finds where it’s coming in before any leak and flashing repair is planned.
After a storm or earthquake
A falling limb, a hard windstorm or a strong shake can crack masonry or shift a flue out of sight. If the house took a hit, have the chimney looked at before the next fire.

What an inspection looks at
Firebox, damper and smoke chamber
Cracked or missing firebrick, a damper that sticks or doesn’t close, gaps in the smoke chamber, and heat marks around the fireplace opening.
The flue and liner
Whether the flue is clear, how much has built up, and whether the liner appears continuous and intact where it can be seen. CSIA’s written procedure treats an eighth of an inch of buildup as the point to sweep or recommend sweeping.
The appliance connection
Where a stove, insert or gas appliance joins the chimney, and whether the chimney appears suited to what’s attached.
Masonry, crown and cap
Brick faces, mortar joints, the crown’s surface and edges, and the cap, which together take the brunt of the weather.
Flashing and signs of water
The seal where the chimney meets the roof, a common entry point for water, plus any staining indoors that suggests water is getting past it.
A photographic record
Conditions are photographed as found, and if repair follows, the after photos match those angles wherever that’s practical. Every photo is yours to keep.
Why the inspection comes before any repair
Chimney problems rarely announce where they start. A ceiling stain can trace back to the crown, the flashing or the cap, and a smoky fireplace can be a liner problem rather than a dirty flue. Quoting chimney repair before looking risks paying to fix the wrong thing.
Relining is the clearest case. CSIA and NFPA 211 both call for a Level II inspection, which includes a scan of the inside of the flue, before a chimney is lined or relined. If a new liner or an insert is on your list, mention it when you get in touch so the scope can be discussed before the visit.
Inspection, sweeping and the NFPA 211 levels
An inspection and a chimney sweep are separate jobs that are often booked together: one judges condition, the other removes buildup. A heavily coated flue can hide cracks and gaps, so you’ll be told if it needs cleaning before it can be properly judged.
NFPA 211, the national standard for chimneys, fireplaces, vents and solid fuel-burning appliances, has a chapter on inspecting existing chimneys that defines three inspection types: Level I, Level II and Level III. Some cities adopt it directly as code, while elsewhere it’s treated as a guideline. If a sale contract, lender or insurer asks for a particular level, say so up front.
What affects the price of an inspection
An inspection is mostly time and access, and what it takes depends on the chimney and on why you want it looked at.
- Why you’re inspecting
- A routine yearly look is a smaller job than one after a chimney fire or ahead of relining, where more of the system has to be reached and documented.
- Flues and appliances
- A chimney serving a fireplace and a furnace, or two fireplaces, has more to examine than a single flue.
- Roof height and condition
- A tall chimney or a steep, wet or mossy roof takes more setup to reach.
- Hidden sections
- Chimney runs through attics, crawl spaces or finished walls take more work to get to than a chimney visible from the room and the roof.
- Buildup that hides the liner
- If deposits cover the surfaces that need to be judged, cleaning comes first, and that is separate work.
You get a written scope and price before any repair work begins.
What chimneys around Puget Sound have been through
House age is one factor. In Seattle, about one in five of the city’s roughly 411,700 housing units was built before 1940 and about a third before 1960. Wherever your house is, a chimney that old may have been relined, patched or never touched, and an inspection is how you find out which.
Weather is another. Seattle-Tacoma International Airport’s climate normals record measurable precipitation on about 156 days a year, and brick, mortar and crowns absorb that wear every season. Conditions shift across the communities Chimney4u serves, with foothill and valley areas generally wetter and colder than the airport. In Seattle, the city’s rule on repairing unreinforced masonry chimneys also cites earthquake vulnerability as its reason for existing.
Questions about chimney inspection
How often should a chimney be inspected?
Once a year is the usual recommendation, and the EPA passes it along from fire officials for wood-burning stoves, fireplaces and their chimneys. Book sooner after a chimney fire, a leak, a storm or a change of appliance.
Does buying or selling a house call for a particular inspection level?
That depends on the purchase contract and on what the city or county at your address has adopted, since NFPA 211 is code in some jurisdictions and not in others. Check with your agent or the contract, and tell us what it asks for when you get in touch.
We had a chimney fire. What should we do now?
Stop using the fireplace or stove until the chimney has been inspected, even if the fire went out on its own. Photograph anything you can see, such as debris on the roof or ground, before it’s cleaned up. Depending on the damage, CSIA says the fix can range from replacing flue tiles to installing a new liner system to rebuilding the chimney. If you’re filing an insurance claim, ask your insurer what documentation it wants.
Does an inspection include cleaning the chimney?
No. Cleaning is a separate job, though the two are often booked together. If the inspection finds buildup worth removing, or enough to hide the liner, you’ll hear that along with everything else.
Will I get a repair quote on the spot?
Not before the inspection is done. If repair is needed, you receive a written scope and price, and nothing is scheduled until you say yes. The photographs are yours either way, so you can compare quotes or get another opinion.
