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.

Why Alcott Chimney Sweep Is Cotati’s Preferred Chimney Inspection Company
Since 2002, Alcott Chimney Sweep has earned a strong local reputation in Cotati by doing plain work and telling the truth about what we find. Ruben Castellano built this company on the idea that a homeowner should never open the door to a stranger they weren’t expecting, so every technician is vetted through the Threshold Standard: background-checked, identity-verified, uniformed, and sent to you by name and photo before the truck leaves.
We know Cotati’s housing stock. We know the tract homes built off Gravenstein Highway in the 1960s and 70s, the rental corridors along the city’s eastern edge, and the way Petaluma Gap wind drives moisture into flues all winter. That local knowledge means our inspections go looking for the problems Cotati actually gets, not a generic checklist. And every inspection comes with a written price before any work starts, a written guarantee on any repair we recommend, and a free return visit if that repair fails within the coverage period.
Fireplace Inspection in Cotati
A Fireplace Inspection in Cotati is the fastest way to know whether your fireplace is safe to burn or quietly deteriorating under the marine moisture that defines this stretch of Sonoma County. We look at the firebox, damper, smoke chamber, flue, chimney cap, crown, and flashing, then give you a straight written report with photos. For Cotati homeowners, one question comes up more than any other: how much water has gotten in through the cap or crown during those foggy, wind-driven winters.
Level 1 Inspection
This is the right inspection when you’ve used the fireplace regularly and nothing has changed since the last time it was serviced. We check all readily accessible portions with a strong light, document creosote levels, and note any visible rust or spalling. A Level 1 inspection in Cotati runs $189 – $249. Most homeowners combine it with a cleaning, since we’re already at the flue.
Camera Inspection
When we can’t see the full flue by eye, or when a Level 1 turns up something questionable, we run a camera down the liner and show you exactly what the inside looks like. This is especially valuable in Cotati because so many 1950s – 1980s tract homes still have original terra cotta liners that crack in ways you can’t spot from the rooftop. A camera inspection in Cotati runs $249 – $349 and becomes part of any Level 2 or Level 3 inspection we perform.
Chimney Inspection Services in Cotati
Chimney Inspection Services in Cotati from Alcott cover the full range: Level 1, Level 2, and Level 3 inspections, plus dedicated camera and flue inspections, and real estate inspections for home sales. Because Cotati sits squarely in the Petaluma Gap wind corridor, our standard inspection protocol assumes the worst about galvanised steel components. We go looking for pinhole rust-through, wind-lifted flashing, and crown cracks holding water, because those are the failures we see week after week here.
Level 2 Inspection
A Level 2 inspection is what Cotati homebuyers need, and what we recommend anyone get after an earthquake, a chimney fire, or a change to the system. It includes everything in a Level 1 plus attic and crawlspace access, video scanning of the interior flue, and an assessment of the chimney’s exterior. In Cotati’s housing market, where homes change hands regularly and many were built before modern liner standards, a Level 2 inspection runs $349 – $549.
Real Estate Inspection
When a Cotati home goes under contract, the last thing anyone wants is a failed inspection that stalls closing. We provide written real estate inspection reports the same day, with photos and plain-English explanations of anything flagged, plus a repair scope and price range. Realtors throughout Cotati, Rohnert Park, and Petaluma call us because our reports hold up under buyer-side scrutiny. Real estate inspections in Cotati run $349 – $549 depending on the system and access.

What the Petaluma Gap Does to Cotati Chimneys
Most chimney companies treat Cotati like any inland Sonoma County town. That’s a mistake. Cotati sits dead-center in the Petaluma Gap wind corridor, a natural funnel that channels cool, moisture-laden Pacific air inland through the Santa Rosa Plain. In practical terms, your chimney cap, crown, and flashing live in a near-constant marine mist from November through April. A galvanised cap that would last 15 years in Windsor or Cloverdale often shows rust-through in Cotati in half that time. Flashing lifts, crowns crack, and water makes its way into the smoke chamber. This is why we push stainless caps and two-part crown seals on almost every Cotati inspection. It costs a bit more up front, but it ends the replacement cycle.
Cotati’s residential core also carries specific risk from age. Most of the city’s tract homes were built from the 1950s through the 1980s, which means their original terra cotta flue liners are now 40 to 70 years old. Terra cotta doesn’t fail gracefully. North Bay seismic activity and years of hot-cold cycling crack those liners from the inside out, and once a liner spalls, smoke and carbon monoxide have a direct path into the chase or the house framing. A camera inspection reveals this in minutes. We’ve pulled cracked liner shards from Cotati fireboxes that the homeowner had been burning on top of for years, entirely unaware.
Then there are the rentals. Cotati borders Sonoma State University on the Rohnert Park side, and a large share of the housing stock along the city’s eastern edge cycles through student renters. Landlords defer chimney maintenance for years. A landlord on the east side of Cotati near the Sonoma State rental corridor called us about a fireplace that hadn’t been touched in years. Our tech found the damper seized shut with rust, a galvanised cap rusted through at the seams, and third-degree creosote glazed along the flue liner, all consistent with the damp Petaluma Gap air and long-deferred maintenance. We freed the damper, swept the flue, replaced the cap with a stainless Olympia unit, and rebuilt the chimney crown with a flexible sealant to stop the water intrusion that was driving the whole problem. That’s a typical Cotati job for us. The pattern repeats: no cleaning history, seized damper, advanced creosote, a corrosion problem nobody knew was there.
Trusted Brands We Service in Cotati
We carry and install professional-grade trade materials in Cotati, including Famco caps and liners, Copperfield flashing and chase covers, and DuraFlex liner systems. These are the brands chimney professionals specify, not box-store substitutes, and we stock common Cotati sizes in our Bay Area warehouse so we’re not waiting on a ground shipment when your inspection turns up a rusted cap that needs replacing. If your chimney needs any repair we identify, we tell you the exact brand and model line before work begins, with a written price.
Common Chimney Inspection Problems We See in Cotati Homes
- Galvanised caps rusted through at the seams. The Petaluma Gap’s marine moisture attacks galvanised steel from the outside in. A cap that looks fine from the ground can have pinhole rust-through along the seams, letting water run straight down the flue. We replace these with stainless.
- Original terra cotta flue liners cracked and spalling. Cotati’s 1950s – 1980s tract homes carry 40 – 70-year-old liners that crack from thermal cycling and North Bay seismic activity. The only way to confirm this is with a camera inspection; by eye, the firebox often looks fine.
- Seized dampers in student rental corridors. Along Cotati’s eastern edge, fires that haven’t been serviced in years often have dampers frozen with rust. A seized damper means smoke can’t vent properly and carbon monoxide risk climbs. We free most dampers without replacing them unless the damage is severe.
- Crown cracks holding water from wet winters. Cotati’s foggy, damp winters push water into any crown crack, and freeze-thaw cycles along the Gap widen those cracks seasonally. A cracked crown is a leading cause of water in the smoke chamber and firebox staining.

FAQs About Chimney Inspection in Cotati
Cotati sits directly in the Petaluma Gap wind corridor, which pulls cool, moisture-laden marine air inland across the Santa Rosa Plain for most of the winter. Galvanised caps, flashing, and chase covers in Cotati are bathed in that marine moisture all season, so they corrode from the outside in far faster than the same components in drier inland towns. We replace rusted galvanised components with stainless as a matter of routine on Cotati jobs. Call (336) 863-3889 for an inspection that specifically evaluates corrosion.
Every year, even if you don’t burn often. Cotati’s persistent winter damp and marine air degrade mortar joints, caps, and metal damper components whether the fireplace is used or not. Annual inspections catch crown cracks and cap rust before they become water intrusions. If you burn wood regularly from November through March, pair the inspection with a sweep. Call (336) 863-3889 to schedule.
Third-degree creosote is the glazed, tar-like form of creosote that hardens onto flue walls and is significantly harder to remove than the dry, flaky first-degree form. Cotati’s damp winter conditions accelerate glazed creosote formation because moisture helps the tar condense and cure inside the flue. It’s a serious fire risk and typically requires chemical treatment or mechanical removal. Our Cotati inspections document creosote stage in the report. Call (336) 863-3889 to have yours checked.
It usually means rust. Cotati’s marine moisture attacks the metal damper plate and its hinge mechanism, and in rental properties where the fireplace sat unused for years, the damper often seizes completely. A seized damper prevents proper venting and raises carbon monoxide risk if someone tries to burn with it closed. Most seized dampers can be freed, lubricated, and brought back to function without replacement. Call (336) 863-3889 and we’ll assess it with a Level 1 inspection.
Yes, and sooner than you’d think. In Cotati’s Petaluma Gap conditions, a galvanised cap that looks fine from the ground is often rusted through at the seams within 5 to 7 years. Stainless caps from brands like Olympia or Famco don’t corrode the way galvanised steel does, and they typically outlast the roof they’re mounted on. When we inspect Cotati chimneys and find any galvanised cap showing rust, we recommend replacement with stainless as a standard practice. Call (336) 863-3889 for a free quote on replacement.
