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.

AfterChimney Company in Cotati, CA
Chimney work in Cotati comes down to two things: wind and old masonry. The Petaluma Gap funnels cool, damp Pacific air through this stretch of Sonoma County most months of the year, and that steady pressure finds its way down chimneys in ways we rarely see in drier inland towns. Most of the homes were built between the 1950s and 1980s, and their terra cotta flue liners are now 40 to 70 years old. That combination, persistent wind plus aging clay, means Cotati homeowners should expect a camera inspection alongside every sweep, not as an add-on, but as the only way to know what’s actually happening inside the flue.
We’re Alcott Chimney Sweep, and we do three things in Cotati: chimney sweeping, chimney inspection, and gas fireplace repair. Each has its own page on this site with pricing and specifics. If you need to reach us, call (336) 863-3889 and a live person answers, no voicemail menu.
Why Cotati Homes Are Different
Cotati sits squarely in the Petaluma Gap wind corridor, a natural funnel that channels cool, moisture-laden air inland from the coast across the Santa Rosa Plain. For a chimney, that means chronic downdraft pressure, air pushing back down the flue whenever the wind picks up. In practical terms, Cotati homeowners notice smoke spilling into the living room on breezy days even when the damper is open and the fire is burning well. It’s not bad technique. It’s the geography.
That damp marine air also changes the creosote itself. In drier parts of Sonoma County, like Windsor or Cloverdale, deposits tend to be dry and flaky, what the trade calls Stage 1 or Stage 2 creosote. In Cotati, we more often find glazed Stage 3 creosote, the tar-like, hard buildup that forms when moisture cycles through the flue between fires. Stage 3 is serious. It’s fuel-dense, stubborn to remove, and the leading cause of chimney fires. It also requires different tools and more time than a standard sweep.
Then there’s the housing stock. Most Cotati homes were built during the city’s main growth years between the 1950s and 1980s. The original masonry fireplaces are still in place in many of them, with terra cotta liners that have been thermal-cycling for half a century. Add North Bay seismic activity, and hairline cracks are common. A crack that looks trivial can let heat and gases reach combustible framing. That’s why we tell Cotati homeowners: if it’s been more than a year since a camera inspection, let’s look.
Our Main Cotati Services
Most Cotati homeowners call us for one of two things: a chimney that needs cleaning before burning season, or an inspection that came back flagged from a home sale. Gas fireplace repair runs a close third. Here’s what each involves locally.
Chimney Sweep in Cotati
A standard sweep in Cotati removes creosote, soot, and any debris that’s collected since the last burn. Given the Petaluma Gap’s moisture, we’re often working with Stage 3 glazed creosote here, which means rotary tools and more time than a light-duty dusting job. We also check the damper because in older Cotati homes, especially rentals along the city’s eastern edge, dampers are frequently seized with rust from deferred maintenance. Full details, including pricing, are on the Chimney Sweep in Cotati page.
Chimney Inspection in Cotati
Every inspection in Cotati should include a camera pass. Our housing stock is old enough that liner cracks from thermal cycling and seismic activity are the norm, and you can’t see that from the top or the firebox. We document everything with photos and show you exactly what we found before recommending anything. If we tell you a liner needs work, you’ll have images in hand. The Chimney Inspection in Cotati page covers what each inspection level includes.
Gas Fireplace Repair in Cotati
Gas fireplaces in Cotati see heavy use from November through March, and the humidity during the off-season is rough on igniters, thermocouples, and gas valves. We service and repair major brands, including the professional lines we install and maintain, like Olympia Chimney, Famco, Copperfield, and DuraFlex. If it’s not lighting or the flame looks weak and yellow, call before burning season gets close. Details are on the Gas Fireplace Repair in Cotati page.
