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 cleaning in Cotati, CA typically runs $198 for a standard sweep, and most Cotati homes need one every one to two years depending on how often the fireplace gets used through the damp Sonoma County winter. Flint Chimney Sweep handles the full scope, from routine sweeps to full chimney inspections and repairs, and every job starts with a written price so there are no surprises when the invoice lands. Call us at (830) 251-4560 to schedule.
Cotati’s housing stock runs older than a lot of Sonoma County. Many of the homes around downtown and the Gravenstein Highway corridor were built in the 1960s through 1980s, which means a lot of masonry fireplaces, a lot of original clay tile liners, and a lot of settling that shows up as cracked mortar joints. The wet winters do not help. Creosote absorbs moisture, which makes it heavier, stickier, and more acidic against the liner. That is a different job than the dry, powdery creosote you see up in the Sierra foothills. Our crews see this every week, and we bring the right brushes, rods, and camera equipment to match the condition, not a one-size-fits-all kit.
Why Cotati Homes Are Different
Cotati sits in the Santa Rosa Plain, which means the marine layer rolls in most evenings from late spring through early fall, and winter rains saturate everything from October through March. For a chimney, that means a cycle of wetting and drying that works mortar joints loose and accelerates spalling on older brick. Homes near Cotati Creek and down by Helen Putnam Regional Park get more of that damp air than places up on the higher lots east of Highway 101.
The housing stock itself is mixed. There are mid-century ranchers near downtown with original masonry chimneys, 1970s and 1980s wood-sided homes off Old Redwood Highway, and a few newer builds east of town that use prefabricated fireplaces and metal flues. The older masonry work here often has clay tile liners long past their usable life and mortar crowns that have gone soft from decades of coastal moisture. Inspection standards matter more in Cotati than in a drier inland city, because hidden water damage travels faster once it gets into the throat of the chimney.
Our Main Cotati Services
The two calls we get most from Cotati homeowners are routine chimney sweeping and inspection work, followed closely by repair projects once the camera sees what is actually going on inside the flue.
Chimney Sweep in Cotati
A standard Chimney Sweep in Cotati removes the creosote and soot that build up from burning wood through the coastal humidity cycle. We run brushes sized to your flue, clean the smoke chamber and damper, and haul the debris out. In Cotati, we often find creosote has glazed over from moisture absorption, which requires more effort than the dry powder a lot of homeowners picture. Pricing is straightforward, and the quote includes everything from rooftop access to the final vacuum of the firebox.
Chimney Inspection in Cotati
Every Chimney Inspection in Cotati we perform uses a camera, not a flashlight and a guess. That matters here because water intrusion remains the biggest threat to Cotati chimneys, and the visual evidence shows exactly where a flue has cracked or a mortar joint has opened up. We deliver a full write-up and make recommendations only when the camera supports them. If the flue is clean and sound, we say so plainly and do not push work that is not needed.
Chimney Repair in Cotati
When an inspection turns up damaged liner sections, cracked crowns, or deteriorating brick, our Chimney Repair in Cotati page covers what the repair work involves and what it costs. We typically use HeatShield for liner repairs, and we will tell you whether a full replacement with a DuraFlex or Olympia Chimney liner is the better call. Every repair carries a written one-year guarantee under our 365-Day Done Right Promise, which means if the covered repair fails within a full year, we come back at no charge.
