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.

Chimney Leak in Cotati
A chimney leak in Cotati is usually one of three things: a spalling crown that is letting water soak into the masonry, failed flashing where the chimney meets the roofline, or a cracked flue liner that is allowing moisture into the chase. The first sentence we hear from most Cotati homeowners is “we thought it was a draft,” followed by water stains on the ceiling near the fireplace. Water intrusion is routinely misdiagnosed as a draft problem, and that leads to unnecessary chimney cap or liner work. We find the source before we recommend a fix.
How We Find the Leak
We start with a Level 2 inspection, which includes a camera scan of the flue interior and a close look at the crown, flashing, and chase top from the roof. The camera shows us cracks in clay liners, separated mortar joints, and rusted damper components that hold water. If the crown is spalling, we document it with photos and give you a written repair quote on the spot.
What a Leak Repair Costs
A chimney leak repair in Cotati commonly runs $350 – $900 for flashing or crown sealing work. If the liner itself is cracked and letting water through, that is a bigger job: flue relining with a DuraFlex or HeatShield system typically runs $2,800 – $5,500 depending on flue length and access. We won’t recommend a liner replacement unless the camera footage shows a crack or separation that justifies it. You’ll see the photo before you approve the work.
Chimney Camera Inspection in Cotati
A chimney camera inspection in Cotati is the only way to see what’s actually happening inside a flue that’s been sitting unused since spring. Creosote buildup, cracked clay liner tiles, animal nests, and separated mortar joints are all invisible from the firebox. The camera shows us everything, and you get the photos in a written report the same day. Most camera inspections in Cotati run $189 – $249 when done as part of a standard inspection.
What the Camera Shows
The camera runs the full length of the flue, from the smoke chamber up through the crown. We look for first, second, and third-degree creosote, cracked or missing liner tiles, gaps in the mortar joints, and any obstruction that could block draft or trap heat. We also check the damper seat and the smoke shelf, which is where creosote and debris collect first in older Cotati ranch houses.
When You Need One
You need a camera inspection in Cotati if your chimney has not been used in six months or more, if you’ve had water stains near the fireplace, if you smell a sweet or smoky odor on humid days, or if you recently bought the home and inherited an unknown chimney history. Real estate transactions in Cotati almost always require a Level 2 camera inspection; we do those regularly for buyers and sellers across Rohnert Park and Cotati.
Trusted Brands We Service in Cotati
We stock and service chimneys built with components from Copperfield, Famco, and DuraFlex, which covers most of the pre-fab and masonry fireplaces you’ll find in Cotati homes. If your chase cap came from Famco or your liner system is DuraFlex, we can source the matching components without waiting on a special order. That matters when the rainy season is a month out and your crown is already letting water in. We keep common Cotati replacement parts on the truck so most repairs go from inspection to done in a single visit.
Common Chimney Inspection Problems We See in Cotati Homes
- Spalling clay flue liners in mid-century homes. Cotati’s 1950s and 1960s ranch houses and Eichler-style builds were constructed with original clay liners that are now 60 to 70 years old. Moisture combined with decades of heating cycles causes the liner tiles to flake and crack. You won’t see it from the firebox. The camera will.
- Raccoon and bird nests during the off-season. Cotati’s mild climate means chimneys sit unused for months. Raccoons, squirrels, and birds move in through uncapped flues. We regularly pull nests out of flues on East Cotati Avenue and in the older ranch subdivisions near downtown.
- Water intrusion through failed crowns and flashing. Cotati gets meaningful winter rain, and a spalling crown or corroded flashing lets that water into the masonry. Hairline cracks widen with every freeze-thaw cycle. What starts as a $500 crown repair becomes a $3,000 liner problem if it is ignored for two or three winters.
- Creosote buildup from occasional shoulder-season fires. Cotati homeowners often burn a few fires in October and November, then let the chimney sit until February. Those low-temperature fires produce first and second-degree creosote that hardens into a glossy, flammable coating. It needs a mechanical brushing, not just a quick sweep.

FAQs About Chimney Inspection in Cotati
Once a year, before you start burning regularly in the fall, is the right cadence for most Cotati homes. If your chimney sits completely unused for 12 months or more, an annual inspection still catches the animal nests, water damage, and mortar deterioration that happen whether you burn or not. If you burn more than two cords a season or have a wood stove, inspect twice a year and sweep more often. Call (830) 251-4560 and we’ll tell you plainly whether you need a sweep or just an inspection.
A Level 1 inspection is a visual check of the accessible parts of the chimney and is appropriate when nothing has changed since the last inspection. A Level 2 inspection adds a camera scan of the flue interior and is required when you’re selling or buying a home, after a chimney fire, or after any major weather event. A Level 3 inspection is the most invasive and involves opening up part of the chimney or flue to access hidden areas, usually because a Level 2 camera scan found damage that warrants a closer look. Most Cotati homeowners need a Level 1 or Level 2. We’ll tell you which one applies before we book.
Yes. The camera shows creosote buildup stage by stage, from first-degree flaky soot through third-degree glazed creosote that is a serious fire risk. You’ll see the footage yourself, and our technician will point out exactly how much buildup is on your flue walls and what level of cleaning it requires. If the buildup is light, we’ll tell you the chimney can wait. If it’s glazed, we’ll show you why a chemical treatment plus mechanical brushing is necessary. Call (830) 251-4560 to schedule a camera inspection so you can see it for yourself.
It does. Cotati’s mid-century ranch houses and Eichler-style builds were constructed with minimal clearance to combustible framing and original clay flue liners that are now past their service life. We look specifically for spalled liner tiles, cracked mortar joints, and insufficient clearance between the flue and wood framing, because those are common in homes from that era and they are exactly what a basic visual sweep misses. We also check the crown and flashing closely, since 1950s flashing details are often inadequate by modern code. If your home is from this period and has its original chimney, schedule a Level 2 camera inspection before you burn again.
No, and you should be wary of any company that does. A proper chimney inspection requires a scheduled appointment so our technician can spend the full 60 to 90 minutes on your roof and in your firebox without rushing the job. No same-day dispatch, no drive-by glance. What we do promise is a written price before the work starts, a written photo report when it’s done, and a live person who answers when you call (830) 251-4560 to book.
