Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across Napa
A chimney inspection in Napa typically costs $189 – $495 depending on the level, and a Level 2 camera inspection runs $325 – $495. Most Napa homes need a Level 2 because the housing stock skews older and wood-burning fireplaces are common. You’ll get a written price before we book, a camera report you can actually see, and a straight answer on whether you need a sweep or can wait. Call (830) 251-4560 and a live person answers, day or night.
We work throughout Napa, from the Victorians near Fuller Park to the ranchers out Browns Valley Road and the newer construction around Silverado. Dispatch is coordinated from our San Francisco Bay Area office, but our crews work Napa streets every week. We know what a 1940s flue liner looks like after sixty Napa winters.
Why Flint Chimney Sweep Is Napa’s Preferred Chimney Inspection Company
Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and we operate under The Garrison Standard: written price before any work starts, background-checked uniformed technicians, and a one-year written guarantee on every repair. Our Chimney Inspection team documents everything with photos. You see what we see.
Napa homeowners have told us the same story for years: a company quotes a number on the phone, walks the roof, then finds two thousand dollars of “necessary” work. That does not happen with us. The price you approve before booking is the price on the invoice. If a covered repair fails within 365 days, we come back at no charge under the Done Right Promise. No argument, no re-quote.
We answer the phone with a live person 24 hours a day. Not a callback service. When you call about an inspection in Napa, you talk to someone who can schedule it.
Chimney Flue Inspection in Napa
A Chimney Flue Inspection in Napa is the part of the job that actually tells you whether your chimney is safe to burn. We run a camera up the flue (the vertical passage that carries smoke out of the house) and document the liner condition, mortar joints, and creosote buildup. On 1920s – 1950s Napa houses, a flue inspection almost always reveals something a flashlight from the firebox misses: hairline cracks, spalled mortar, first-degree creosote that is already glazing.
This inspection matters most before your first burn of the season, after a chimney fire, or when you are buying a house. In Napa’s real estate market, a Level 2 camera inspection is standard practice for escrow, and for good reason. Sellers rarely know what is inside the flue.
What the Camera Shows
A camera inspection catches what a visual check cannot: internal cracks in clay tile liners, gaps at mortar joints, and creosote accumulations above the smoke chamber (the angled area above the firebox where smoke slows down and deposits build). We photograph everything and send you the report the same day. You keep it, you review it, you decide what to do next.
When Napa Homeowners Schedule
Most calls come in October and November, before the first rain and the first fire of the season. But an inspection is just as common in the spring, when slab leaks and wet weather expose crown damage and flashing failures. If you smelled smoke in the house last season, schedule now. The answer will not change in twelve months, and the repair will not get cheaper.
Chimney Fire in Napa
A Chimney Fire in Napa usually starts the same way: a homeowner burns a few seasons of fires without an inspection, creosote builds to second or third degree, and one hot fire ignites it. Creosote is the tar-like residue from wood smoke that condenses on the flue walls. At third degree it is a hard glaze that burns like fuel and cannot be brushed out.
If you have had a chimney fire, even a small one, you need a Level 2 inspection before you burn again. The heat can crack the flue liner, warp the damper, and break mortar joints. A house that survived one chimney fire may not survive a second.
What We Check After a Fire
After a chimney fire, we inspect the full flue system: liner integrity, smoke chamber condition, chimney crown, cap, and flashing. We look for heat damage at every point where fire could have escaped the flue. The camera report shows you exactly what we found and what actually needs repair.
The Honest Answer on Creosote
Third-degree creosote cannot be removed with a wire brush. It requires chemical treatment, often multiple applications, before any mechanical cleaning can happen. On a 1948 bungalow near Fuller Park, we found second-degree glaze above the smoke chamber that the homeowner never saw from the firebox. We wrote the photo report that day, flagged the crown and flashing as separate repairs, and scheduled the chemical treatment first. Brushing it would have done nothing.
Trusted Brands We Service in Napa
We inspect and work with flue liners and components from brands you can verify: Olympia Chimney, DuraFlex, Copperfield, HeatShield, Famco, and Gelco. When a Napa home needs a liner replacement, we specify the right product for the job, not the one with the highest margin. We keep common parts stocked for the Napa area, which means less waiting when a repair is approved. The brand names are in your written quote, so you can look them up before you sign anything.
Common Chimney Inspection Problems We See in Napa Homes
- Spalled mortar joints in 1920s – 1950s flue liners. Decades of heat cycling break down the mortar between clay tiles. The gaps let heat and gases reach the chimney structure.
- Second-degree creosote glaze in wood-burning fireplaces. Napa’s cool wet winters mean people burn more, and shorter chimneys on older bungalows do not draw hot enough to burn creosote off naturally.
- Cracked chimney crowns from seismic settling. Napa sits in earthquake country. Crown cracks let water in, and water plus creosote makes an acidic slurry that eats mortar.
- Gas inserts that were never re-inspected. A home with a gas insert still needs an annual inspection per NFPA 211, but many have not been looked at in years. The flue may be fine, or it may have debris from the old wood-burning days.
Pricing for Chimney Inspection in Napa, CA
Here are real numbers for the Napa market. A Level 1 visual inspection runs $189 – $249. A Level 2 camera inspection runs $325 – $495, and we recommend Level 2 for most Napa homes because of the older housing stock and wood-burning fireplaces. A Level 3 inspection, which involves removing portions of the chimney structure to access concealed areas, runs $1,000 – $5,000 and is rare unless there has been a chimney fire or major structural question.
What changes the price? Chimney height, roof pitch, and whether the flue has an accessible cleanout. A two-story Victorian with a steep roof takes longer than a single-story rancher. You get the exact price in writing before we schedule, and it does not change when the tech arrives.

FAQs About Chimney Inspection in Napa
Yes, you need an inspection even if you burn once or twice a year. The issue is not how often you burn; it is what has accumulated over time and what condition the flue is in. NFPA 211, the national fire safety standard, calls for an annual inspection regardless of use. If you have a gas insert that has not burned wood in a decade, the honest answer is often an inspection without a sweep, and we will tell you that plainly. Call (830) 251-4560 for a free estimate.
A Level 1 inspection is a visual check of the accessible portions of the chimney: firebox, damper, flue opening, and exterior. It is fine for a chimney that has not changed use and has no known problems. A Level 2 inspection adds a camera scan of the full flue interior, the smoke chamber, and the exterior structure, including the attic and crawl spaces where the chimney passes through. We recommend Level 2 for most Napa homes, every real estate transaction, and any chimney with a history of water damage or a chimney fire. Call (830) 251-4560 to book either.
NFPA 211 says a chimney needs sweeping when there is 1/8 inch or more of creosote buildup, regardless of time since the last sweep. For a wood-burning fireplace in Napa used regularly from November through February, that usually means once per year. For a gas insert, the flue may need clearance of debris but often not a full brushing. The right answer is based on what the camera shows, not a calendar. Call (830) 251-4560 and we will give you a written quote.
No. Third-degree creosote is a hardened glaze that mechanical brushing does not remove. It requires chemical treatment, typically multiple applications over days or weeks, before a brush can be used safely. Attempting to brush it can score the flue liner and make the problem worse. If a camera inspection shows third-degree glaze, we will show you the photos and write the treatment plan in your quote. Call (830) 251-4560 for an exact price.
We work with Olympia Chimney, DuraFlex, Copperfield, Famco, HeatShield, and Gelco products.
