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.
Fast, Reliable Chimney Inspection Across Sonoma
A chimney inspection in Sonoma typically runs $189 – $449 depending on the level, and a Level 2 inspection with a camera is the standard we recommend for most homes here. We’re talking video documentation of your flue liner, smoke chamber, and firebox, delivered with a written report you can actually read.

Call (830) 251-4560 to book.
Why Flint Chimney Sweep Is Sonoma’s Preferred Chimney Inspection Company
Homeowners in Sonoma call us because we put the scope, price, and guarantee in writing before work begins. That’s not a sales pitch. It’s The Garrison Standard, the operating code every Garrison Partners location follows, and it applies to every inspection we do from Boyes Hot Springs to the east side of Sonoma.
We’ve been part of the Garrison Partners family since 2002, and the 365-Day Done Right Promise applies to any repair we recommend after an inspection. If a covered repair fails within one full year, we return at no charge. No fine print, no re-diagnosis fee. Hank Delano leads our team, and he holds every tech to that standard.
Our technicians know Sonoma’s housing stock. When we walk up to a 1930s bungalow off East Napa Street or a 1950s ranch near the Sonoma Plaza, we already know what to look for: original brick fireboxes, clay tile flues, aging crowns, and seismic retrofit work that may or may not have included the chimney. That local familiarity means a faster, more accurate inspection.
Phones are answered by a live person 24/7. When you call at 9 p.m. on a Sunday, someone picks up. Not a voicemail tree, not a callback form.
Level 2 Chimney Inspection in Sonoma
A Level 2 Chimney Inspection in Sonoma typically costs $299 – $449 and includes a full video scan of the flue interior, smoke chamber, firebox, and accessible exterior surfaces. This is the inspection you need if you’re buying a home, selling one, changing fuels, or if the chimney hasn’t been looked at in five-plus years. Most inspections we perform in Sonoma are Level 2 because the housing stock here demands it.
What the camera sees
We run a camera from the firebox up through the flue liner and down from the crown. In Sonoma homes from the 1920s – 1950s, the camera frequently finds things a naked-eye sweep misses: cracked clay tile liners, gaps between tile sections, and creosote that’s advanced from first-degree to second-degree inside the smoke chamber. You get photos, not just our word.
What it costs in real terms
If the Level 2 inspection is part of a sweep, we discount it. A sweep plus Level 2 inspection in Sonoma generally runs $489 – $649 total, depending on flue height and access. If repairs get recommended, the inspection fee is not refunded, but you’ll have a documented record and a written repair quote with a fixed price. You approve it before we do anything.
Chimney Leak in Sonoma
A Chimney Leak in Sonoma, where winter rains arrive between November and March, is usually traced to a cracked crown, failed flashing, or spalling brick, and typical leak repair here runs $250 – $900 depending on the source. We don’t guess. We camera the flue, water-test the exterior, and photograph the failure so you see it before approving the fix.
Why leaks hit Sonoma chimneys hard
Sonoma’s damp winters and mild summers give moisture time to work into old mortar. Original brick fireboxes from the 1930s and 1940s absorb water over decades, and the freeze-thaw cycle isn’t extreme here but steady. Brick spalls, mortar joints open, and water tracks down past the flashing into the attic. By the time you smell it indoors, the damage has usually been running for a couple seasons.
When it can wait
A hairline crack in the crown that isn’t letting water behind the flashing can safely wait until spring. A leak that’s already stained the ceiling or soaked the flue liner should not. We’ll tell you plainly which one you have, with photos to back it up, and a written estimate that doesn’t change when we open the roof.
Trusted Brands We Service in Sonoma
We work with professional-grade chimney materials specified by job, not by margin, including DuraFlex, HeatShield, and Olympia Chimney. When a Sonoma homeowner needs a HeatShield flue liner repair instead of a full liner replacement, that’s what gets quoted. When a crown rebuild calls for a specific product, we name it on the estimate. You’re welcome to verify the brand and the specification independently before approving the work.
Common Chimney Inspection Problems We See in Sonoma Homes
- Deferred inspections due to mild burn seasons. Sonoma homeowners burn a handful of fires per year, so a chimney goes years without a look. First-degree creosote quietly advances to second-degree in the smoke chamber, where it becomes a chimney fire fuel source, not just a cleaning issue.
- Spalling brick masked by paint. Interior paint on 1920s – 1950s fireboxes hides brick that’s flaking and losing structural face. It looks like cosmetic wear. It’s often moisture damage that predates the current owner.
- Seismic retrofit work that skipped the chimney. Many Sonoma homes have been bolted and retrofitted multiple times, but the chimney itself often got left out. We check whether re-flashing or bracing was done to the chimney, which newer tract housing in surrounding towns rarely requires.
- Third-party ‘free sweep’ offers with no camera. These skip the video scan entirely, so a cracked flue liner or damaged smoke chamber goes unreported. Homeowners don’t learn about it until something forces the issue.

FAQs About Chimney Inspection in Sonoma
Once a year, per NFPA 211, regardless of how often you burn. Sonoma’s mild climate means some homeowners skip a year or five, and that’s exactly how first-degree creosote turns into a problem. If you burn less than a dozen fires per season, you can sometimes stretch to 18 months, but not if the flue is unlined or the crown has visible cracks. Call (830) 251-4560 and we’ll help you figure out the right interval for your specific chimney.
A Level 1 is a visual check of the accessible portions, no camera, for a chimney that’s been serviced recently and has no changes. A Level 2 adds a full video scan and is required for real estate transactions, fuel changes, or after an earthquake or chimney fire. A Level 3 is invasive, opening walls or ceilings to access concealed portions of the chimney. Most Sonoma homes need Level 2, and that’s what we quote most often here.
Yes, in two ways. First, the clay tile liner from that era is often cracked or offset at the joints, which a camera will show clearly. Second, your chimney may have been passed over during seismic retrofit work, so we check for signs that re-flashing or bracing was never done. Homes from the 1920s – 1950s in Sonoma share a lot of these conditions. Call (830) 251-4560 to schedule, and mention the home’s age when you do.
No, and anyone who claims otherwise is guessing from the bottom of the firebox and cannot see the upper flue. Third-degree creosote is a hard, glazed, concentrated fuel deposit that only a camera can confirm or rule out. Our standard Level 2 inspection includes the video scan, and we hand you the footage and photos. If it’s clean, you’ll see that too.
Minor crown cracks with no active water intrusion can wait until spring. Spalling brick that hasn’t penetrated the flue can usually wait a season. But a cracked flue liner or a leak already staining your ceiling or attic should not wait, because you’re looking at either a chimney fire risk or structural water damage. We’ll tell you plainly which bucket your problem falls into, with photos, and you decide. Estimates are free: call (830) 251-4560.
