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.

Call (336) 863-3889 to schedule, and you’ll get a written price before any work starts.
Sonoma is different from most Bay Area markets. The chimneys here are older, the fire code is stricter, and the stakes are higher because the entire city sits inside a California Very High Fire Hazard Severity Zone. We’ve spent years learning what those conditions mean in practice, and we bring that knowledge to every Chimney Inspection we perform in town.
Why Alcott Chimney Sweep Is Sonoma’s Preferred Chimney Inspection Company
We’ve built our reputation in Sonoma on one principle: show the homeowner the evidence before recommending anything. Ruben Castellano, who leads our inspection team, trains every technician to treat the camera like the final word. If a liner is cracked, you see it on the tablet. If a smoke chamber is glazed with creosote, you watch the footage before we hand you a single recommendation. No photos, no proposal. That approach matters in a city where old chimneys invite aggressive upselling.
Every technician who arrives at a Sonoma door is background-checked and identity-verified before they ever step on the property. This is the Threshold Standard, and it’s non-negotiable. You’ll know the technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at the door. Not as a courtesy. As a rule.
We answer the phone with a live person around the clock. When something smells like smoke during the first October fire of the season, you don’t want a callback queue.
Fireplace Inspection in Sonoma
Fireplace Inspection in Sonoma means checking the firebox, damper, smoke chamber, and flue for the kind of deterioration that hides behind a working facade. In this city, that facade is usually original masonry. A pre-1950 home near the Plaza can have a firebox that still looks solid while the flue above it has no liner at all. The only way to confirm that is to look with a camera. A Level 1 inspection runs $189 – $240. If we find anything that warrants a closer look, the Level 2 camera scan runs $300 – $450.
What We Check
Damper function, firebox brick and mortar, smoke chamber condition, and the full flue length. We’re looking for spalling mortar, cracked clay tiles, and any gap between the firebox and the flue that would let heat reach framing.
When Sonoma Homeowners Book This
Most jobs come in October and November, right before the first fires of the season. But we also see a steady number of calls in summer from homeowners who want documentation ahead of a real estate sale or a fire-insurance renewal.
Chimney Inspection Services in Sonoma
Chimney Inspection Services in Sonoma cover three levels defined by the National Fire Protection Association. Level 1 is the annual visual check. Level 2 adds a full interior camera scan and is required for property transfers, after any seismic event, or when an appliance is added or changed. Level 3 is invasive, and in Sonoma it’s usually reserved for suspected fire damage or structural failure. Camera inspections run $300 – $450 and include a full video review with you before anything is recommended.
Level 2 Camera Inspections
This is the inspection Sonoma’s older homes actually need. The camera shows what a headlamp and mirror can’t: missing flue sections, third-degree creosote glazing, and misaligned prefab flues behind mid-century walls.

Trusted Brands We Service in Sonoma
When a Sonoma chimney needs a new liner, cap, or spark arrestor, we use the brands chimney professionals specify. We stock DuraFlex liner systems and Olympia Chimney caps locally, so most retrofits don’t wait on shipping from a regional warehouse. We also work with Famco arrestors and Copperfield components, which matters when a fire inspector has flagged an uncapped stack near the Plaza and the fix needs to happen before the next burn.
Common Chimney Inspection Problems We See in Sonoma Homes
- Unlined or crumbling clay-tile flues in pre-1950 homes. The firebox and damper look fine, so a visual check passes. A Level 2 camera reveals the gap between the flue and the surrounding masonry, which is why we default to these on older Sonoma structures.
- Missing spark arrestors on historic crowns. In a VHFHSZ, an uncapped chimney is a code violation under California Fire Code Section 603.5. Many homeowners only learn this when a local inspector flags it after a cleaning.
- Corroded prefab inserts east of the Plaza. The valley’s damp winter fog pits metal flues over time. A Level 1 inspection can miss a misaligned or perforated prefab stack entirely.
- Stop-start burn cycles that build creosote fast. Sonoma homeowners burn hard from November through March, then stop entirely through the dry summer. That cycle layers creosote, and the first October fire is the highest-risk moment of the year.
Pricing for Chimney Inspection in Sonoma, CA
A Level 1 inspection in Sonoma typically runs $189 – $240. A Level 2 with camera runs $300 – $450. If a liner, cap, or crown repair is needed, you’ll get a written price for that work separately, before anything starts. What pushes a quote to the high end? Chimney height, roof pitch, and access constraints on older lots near the Plaza. What doesn’t affect it is pressure. You’ll never get a recommendation without camera evidence, and you’ll never be charged for work we haven’t priced in writing first. Call (336) 863-3889 for a free estimate on any inspection.
On a Craftsman bungalow off East Napa Street, our tech ran a Level 2 inspection with a camera up the original clay-tile flue and found third-degree creosote glazing in the smoke chamber plus spalling mortar joints at the crown. Neither was visible from the ground. We showed the homeowner the footage on the tablet before recommending a HeatShield liner and a new stainless chimney cap with spark arrestor, and later sealed the crown flashing. The point was never the upsell; the camera made the case.
That’s the standard we bring to every Chimney Inspection in Sonoma. Nothing is recommended without evidence you can see for yourself.

FAQs About Chimney Inspection in Sonoma
No, Sonoma doesn’t mandate an inspection for an unused fireplace, but if your home changes ownership, your insurer will often require a Level 2 before renewing or writing a policy, especially in a VHFHSZ. And even an unused chimney is a fire risk if it’s uncapped. We can tell you within a Level 2 scan whether yours is safe to leave alone or needs attention. Call (336) 863-3889 and we’ll walk you through what your insurer is likely to ask for.
Yes. Pre-1950 masonry chimneys in Sonoma were built before flue liners were standard, and the original clay tile has often cracked or crumbled by now. A Level 2 camera inspection is the only way to see that condition. Without it, you’re guessing. We default to Level 2 on any home built before 1950 within a few blocks of the Plaza, and we’ll show you the footage before we recommend anything.
Third-degree creosote is a hard, glazed, tar-like layer that forms when fires burn hot and then cool quickly, exactly the pattern Sonoma’s stop-start burn cycle creates. It’s concentrated fuel, and it doesn’t brush out with a standard sweeping. It has to be seen to be addressed, which is why camera inspections matter so much here. If we find it, we’ll show you the footage and explain your options.
Only if the camera shows yours is missing or damaged. In Sonoma, an uncapped chimney in a VHFHSZ is a California Fire Code violation under Section 603.5, and local fire inspectors have been flagging these regularly since the 2017 Wine Country fires. But you’ll see the photos before we recommend the cap. If yours is intact and code-compliant, we’ll say so and say nothing more. Call (336) 863-3889 to schedule the inspection; the estimate is free.
We install and service DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield materials, the same brands chimney professionals specify. If your older Sonoma home needs a liner resurfaced or a new arrestor installed, you won’t get a box-store substitute. Ruben Castellano’s team keeps DuraFlex and Olympia inventory on hand for Sonoma jobs, so most retrofits don’t wait on a parts shipment.
If you need a chimney inspection in Sonoma, call (336) 863-3889. We’ll give you a written price before any work starts, send a technician whose name and photo you already know, and show you the camera evidence before we recommend a single dollar of repair.
