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 Sweep Across Sonoma
A chimney sweep in Sonoma typically costs $189 – $289 for a standard open-firebox fireplace, and most jobs are done within two hours of arrival. That price includes the full sweep, a camera inspection of the flue, and a photo report you keep. If you live in Sonoma and your fireplace smokes into the room, smells musty, or you can’t remember the last time the flue was actually cleaned, call us at (830) 251-4560 and we’ll give you a written price before any work starts.
We work across the city, from the Victorian-era homes off Broadway to the post-fire rebuilds out toward Agua Caliente and the newer developments near Boyes Hot Springs. Sonoma’s chimneys are not one kind of chimney. And a sweep route here proves it every week. Our Chimney Sweep crews run camera inspections on every single job, because in this city, what a chimney looks like from the top tells you almost nothing about what is happening inside the flue. We serve Sonoma and the surrounding area with the same flat-price, written-in-advance process on every call.
Why Flint Chimney Sweep Is Sonoma’s Preferred Chimney Sweep Company
We have been in business since 2002 as part of the Garrison Partners family of independently owned chimney service companies, and every one of our locations runs on the same Garrison Standard: a written price delivered before work begins, a background-checked and uniformed technician on site, and a written guarantee on every repair. That guarantee is our 365-Day Done Right Promise. If a covered repair fails within one full year of the service date, we return and make it right at no charge. No argument. No re-quote.
What Sonoma homeowners tell us they are tired of, more than anything, is being quoted one number on the phone and handed a different invoice at the door. That is not how we operate. The price you approve before we start is the price you pay when we finish. That applies to every sweep, every inspection, and every repair, on every job in Sonoma.
We dispatch uniformed technicians who arrive inside the window we give you. The phones are answered by a live person around the clock, not a voicemail tree. If you call at 6 a.m. before work or 10 p.m. on a Sunday, a person answers and schedules your sweep. That matters in a town where so many homes are weekend properties and so many owners are trying to schedule service around a day in the tasting room.
Gas Fireplace Cleaning in Sonoma
Gas Fireplace Cleaning in Sonoma is a different job than a wood-burning sweep, and a lot of homeowners assume they can skip it entirely. You can’t. Gas fireplaces produce soot and mineral deposits that coat the glass, clog the burner ports, and reduce the flame from a clean blue to a lazy yellow. We disassemble the log set, brush the firebox, clean the glass with a non-abrasive solution, check the pilot assembly, and make sure the venting is drafting properly. The cost for gas fireplace cleaning in Sonoma runs $149 – $229 depending on the unit.
What the cleaning covers
We disconnect and clean the logs, vacuum the burner tray, clear the pilot orifice, and polish the glass. If your fireplace has a fan kit, we inspect and clean the blower. Every unit gets a draft test before we pack up.
When to schedule it
Most Sonoma homes with gas inserts use them steadily from November through February. If you burn more than four cords a season, or the flame has turned yellow and lazy, you should have the unit cleaned before the next burn. A homeowner who waits until the glass is fully blacked out often needs a new burner rather than just a cleaning.
Chimney Maintenance in Sonoma
Chimney Maintenance in Sonoma is not something you schedule once a decade. It is an annual discipline, and the National Fire Protection Association’s NFPA 211 standard says every chimney should be inspected at least once a year. Maintenance means brushing the flue, checking the crown and cap, verifying the damper opens and closes fully, and running a camera to look for cracks, spalling brick, or a deteriorating liner. A maintenance sweep and inspection in Sonoma runs $189 – $289 for a standard masonry chimney, with the camera inspection included.
What the inspection catches
A proper level-one maintenance visit catches third-degree creosote before it becomes a chimney fire, a shifted cap before water gets into the firebox, and hairline liner cracks before they become a carbon monoxide risk. The camera inspection is not an upsell. It is how we know what you actually have up there.
Small fixes on the same visit
Many maintenance calls end with a small repair done the same day: a new cap from Copperfield or Famco, a patched crown with HeatShield, a replaced damper plate. We carry the common parts on the truck, so you are not waiting for a second visit for a minor fix.
Trusted Brands We Service in Sonoma
We stock and install professional-grade chimney products that Sonoma homeowners can verify independently. Our inventory includes DuraFlex stainless steel flex liners, HeatShield cerfractory sealant for crown and smoke chamber repair, and caps and dampers from Famco and Copperfield. We specify these brands by job, not by margin. If your Sonoma home has a post-Nuns-Fire stainless reline made with a DuraFlex liner, we can service it without ordering custom parts from out of state. That keeps turnaround short during burn season, when every week without a usable fireplace is a week you needed it.
Common Chimney Sweep Problems We See in Sonoma Homes
- Unlined flues in pre-1900 masonry chimneys. Many Victorian and adobe-era Sonoma chimneys were built before modern flue-liner standards existed. The brick or stone is the flue. Those chimneys collect creosote fast and need more frequent sweeping than a lined flue.
- Post-Nuns-Fire stainless relines that get skipped at inspection time. Homeowners assume a new liner means no inspection needed. We find shifted caps and failed flashing on relined chimneys all the time, because fire rebuilds settled and nobody checked.
- Corbeled smoke chambers that kill the draft. We pull dampers on Sonoma Victorian and Craftsman-era chimneys and find smoke chambers that were never parged or corbeled into a shelf. The smoke hits that shelf and rolls back into the room instead of rising.
- Creosote grades overlooked by crews that skip the camera. A flue that looks clean from the top can have third-degree creosote glazing the lower third. We see it constantly, and we grade it by what the camera sees, not by what a flashlight shows.

FAQs About Chimney Sweep in Sonoma
A wood-burning fireplace used regularly during burn season needs a sweep every year, and the National Fire Protection Association’s NFPA 211 standard requires an annual inspection. Sonoma’s pre-1900 unlined chimneys and post-Nuns-Fire relines both need that yearly check. If you burn two or three fires a week from November through March, once a year is the minimum. Call (830) 251-4560 and we’ll schedule it and quote it in writing.
Yes, but the better word is cleaning rather than sweeping. Gas inserts do not produce creosote, but they do produce soot, mineral buildup on the glass, and debris that blocks the burner ports. We clean the unit and inspect the liner. If there is a stainless liner in place, we run the camera to confirm it is intact. The cleaning runs $149 – $229 in Sonoma, and you get the photo report.
A Level 1 inspection is what you get with a standard sweep: we check the readily accessible parts of the chimney, the flue, the cap, and the basic condition. A Level 2 adds a camera scan and is required when you change anything about the system, after a chimney fire, or for a real estate transaction. A Level 3 inspection requires removing part of the structure to access a hidden area and is rarely needed. Most Sonoma homes need a Level 1 every year and a Level 2 when something has changed.
Creosote is the flammable residue left by burning wood, and in its third-degree form it is a glazed, tar-like coating that is the primary fuel in most chimney fires. It is not always removable with a standard brush. Third-degree creosote often requires chemical treatment or rotary removal, and that is exactly why we quote after seeing it, not before. If a sweep quotes you a flat rate over the phone without looking, they are guessing about a fire hazard.
No. We do not promise same-day service, and we will not rush a sweep to fit a same-day promise. A proper sweep and camera inspection takes the time it takes, and Sonoma’s mixed housing stock means some chimneys take longer than others. We schedule in advance, we arrive inside the window we give you, and we finish the job properly. Call (830) 251-4560 for the next available slot and a written quote before you book.
