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 Company in Mill Valley, CA
Chimney work in Mill Valley is different from the rest of Marin, and it comes down to three things: the damp fog that rolls through these canyons, the hillside homes built into the slopes, and the redwood trees that drop needles onto nearly every roof. You don’t need a sweeping company that treats Mill Valley like a generic Bay Area zip code. You need someone who knows why a chimney off Panoramic Highway behaves differently than one in a flat San Rafael tract. Call us at (831) 534-3789 and you’ll speak with a live person who can talk through what your home likely needs before anyone ever drives up.
Why Mill Valley Homes Are Different
Mill Valley’s marine fog isn’t just weather. It’s a chimney problem. When cool, moist air sits inside a flue, condensation forms on the liner walls. That moisture binds with creosote, the tar-like combustion byproduct that builds up every time you burn wood. In drier inland cities, creosote stays flaky and a sweep removes most of it. In Mill Valley, it becomes sticky, dense, and harder to clean; left alone, it’s the primary fuel for chimney fires.
The housing stock amplifies this. Many Mill Valley homes date from the 1950s through the 1970s: ranch-style and contemporary builds tucked into hillsides with multi-story chimneys. A two-story flue on a steep lot often has offset runs, where the chimney bends to follow the roofline or accommodate the slope. Offsets trap creosote where a straight flue wouldn’t, and homes near downtown, with older brick and stone cottages, can have flue runs that are genuinely complex to clean thoroughly.
Then there’s the redwood canopy. Mill Valley’s overhanging trees shed needles, branches, and bark. Add in the squirrels and birds that nest in uncapped flues, and a chimney can go from “needs a sweep” to “needs a full debris removal” in a single season. This is why we treat every Mill Valley job as a cleanup and condition check, not just a brush-through.
Styles & brands we work with





Our Main Mill Valley Services
Mill Valley homeowners call us most often for two things: a thorough chimney sweep before burning season, and an inspection when they buy, sell, or notice something off. Each service has its own Mill Valley page with pricing and process details below.
Chimney Sweep in Mill Valley
A proper sweep in Mill Valley means more than running a brush up the flue. We remove the creosote that the coastal damp has hardened, clear out redwood needles and any animal nesting, and inspect the damper and cap while we’re there. Hillside homes with offset flues take extra care because buildup hides in the bends. You get a photo report of the before and after so you can see exactly what came out of the flue. Learn about our full process and pricing on the Chimney Sweep in Mill Valley page.

Chimney Inspection in Mill Valley
Mill Valley’s moisture problem means liners and dampers corrode faster than you’d expect, especially in homes that sit in fog for days at a time. A camera inspection lets us see what’s happening inside the flue without guessing: cracked clay tiles, rusted steel liners, mortar joints failing, or creosote packed into an offset bend. This matters for anyone buying a hillside home built before modern liner standards. See what a Mill Valley inspection covers on the Chimney Inspection in Mill Valley page.

Gas Fireplace Repair in Mill Valley
Gas fireplaces fail differently near the coast. Moisture in the air gets into pilot assemblies, thermocouples, and control valves, causing intermittent ignition problems or complete shutdown. Many Mill Valley homes also have older gas inserts installed decades ago with parts no one stocks anymore. We diagnose what’s actually wrong, explain whether it’s worth fixing or replacing, and carry professional replacement parts from brands like Olympia Chimney and Copperfield. Details on common repairs and pricing are on the Gas Fireplace Repair in Mill Valley page.

Brands We Service in Mill Valley
We install and repair equipment from manufacturers chimney professionals actually specify: DuraFlex liner systems, Olympia Chimney caps and dampers, Famco, and Copperfield gas components. Because Mill Valley’s marine air is hard on metal parts, we don’t substitute box-store alternatives. For a broader look at what we work with, see our brands.

Whatever the job, you get a written price before we start, and that price doesn’t change mid-job.

FAQs About Chimney Company in Mill Valley
Most Mill Valley jobs are scheduled within two to five business days. During September through December, the peak burning-season prep window, lead times stretch to a week or more. If you have an active chimney concern, like smoke backing up into the house, call (831) 534-3789 and a live person will help you assess urgency.

Mill Valley’s building department reviews repair work on a case-by-case basis. We’ll tell you honestly if a permit is needed before any repair begins.
Hillside access is common in Mill Valley, and most chimneys are reachable with standard extension ladders and safety lines. When a roofline is too steep or the chimney requires a second technician to safely access, we’ll tell you before scheduling and include that in your written quote. We don’t improvise with safety.

What Mill Valley Customers Say
"Good chimney cleaning. They found a small gap in the mortar and quoted the repair, which was a bit more than I wanted to spend. Did the sweep and left the repair for later without any pressure."
- Stuart L."Annual inspection and sweep. He used a camera to check the liner and found a cracked tile I had no idea about. Gave me a written estimate and did not push."
- Janet W."Water was leaking around the flashing. They resealed it and installed a new crown coating. Dry through two heavy rains since."
