We’ve been working the chimneys of Corte Madera for over 42 years. We know the post-war ranch homes between US-101 and the shoreline, the hillside builds near Ring Mountain, and the particular way this town’s geography punishes chimney components. The salt-laden air off San Francisco Bay doesn’t negotiate. It seizes dampers. It rusts flashing. It drives moisture into cracked clay flue tiles during Marin’s concentrated winter rains. Our trucks are stocked for these conditions, because a second trip wastes your afternoon and ours.
Why Hearthstone Chimney Co. of San Francisco Is Corte Madera’s Preferred Chimney Cleaning & Sweep Company
Our reputation in Corte Madera was built one chimney at a time, mostly through neighbors telling neighbors. We’ve swept flues on San Clemente Drive, inspected crowns on Madera Boulevard, and replaced rusted damper assemblies throughout the 94925 zip code. Homeowners here tend to stay put - twenty, thirty, forty years - and they remember which contractors show up when promised and which ones disappear.
We answer the phone with a live person, 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. When you call (855) 408-5567, someone picks up. Our background-checked, uniformed technicians arrive with no-hassle upfront pricing - the number on the estimate is the number on the invoice. Most jobs finish in a single visit. And every job carries our 90-Day Done Right Promise in writing: if it’s not right, we come back. No paperwork to dig up. No arguing.
We document every Level 2 inspection with photos you can see and a plain-English verdict. You’ll understand what we found, why it matters, and what it costs to fix. That’s the Keystone Standard we’ve operated under since 1984.
Our Chimney Cleaning & Sweep Services in Corte Madera
Level 1 Inspection
A Level 1 inspection is the baseline annual service for Corte Madera homeowners who burn regularly and haven’t changed their system. We examine the readily accessible portions of your chimney exterior, interior, and connections. In the flatland ranch homes built during the 1950s through 1970s, we’re checking for the early signs of salt corrosion on the damper and the first hairline cracks in aging clay flue tiles. A Level 1 inspection in Corte Madera runs $189-$289 when bundled with a sweep.
Level 2 Inspection
Level 2 is our most requested service in Corte Madera, and for good reason. This is the camera inspection - we run a high-resolution video up the flue to document every crack, every gap, every stage of creosote buildup. You see the photos. We give you a plain-English verdict. For homes on the bay side of town, this inspection often reveals what a Level 1 cannot: corrosion damage hidden inside the smoke chamber, deteriorated mortar joints behind the liner, or creosote glazing in chimney bends caused by sporadic burning during restricted “Spare the Air” days. A Level 2 inspection in Corte Madera costs $329-$479. If you’re buying a home near Ring Mountain or selling a ranch built in 1962, this is the inspection you want.
Creosote Removal
Corte Madera’s burn pattern is unusual. Bay Area Air Quality Management District “Spare the Air” restrictions concentrate all wood-burning into narrow approved windows. Homeowners burn harder and less consistently. The result is uneven, hardened creosote deposits that resist standard rotary brushes. We’ve developed a targeted approach for this: manual scraping with specialized tools in the bends and shoulders of the flue, followed by rotary sweeping of the straight runs. Heavy creosote removal in Corte Madera runs $289-$419 depending on accessibility and buildup severity. We assess it during the initial inspection and tell you before we start.
Soot Removal & Fireplace Cleaning
The firebox and smoke chamber need their own attention, separate from the flue. In Corte Madera’s older ranch homes, we regularly find soot-packed smoke chambers that reduce draft and send smoke into the room. Our fireplace cleaning includes the firebox, smoke chamber, damper assembly, and hearth extension. Where the damper is seized from salt corrosion - common on San Clemente Drive and the streets running parallel to the bay - we extract and replace it in the same visit. Fireplace cleaning with soot removal in Corte Madera typically runs $249-$369.

Trusted Brands We Service in Corte Madera
We don’t use builder-grade substitutes. For damper replacements in salt-air conditions, we stock stainless-steel units from Olympia Chimney and Famco - materials that resist the corrosion that ruined the original. For flue tile repair and resurfacing, we work with HeatShield refractory sealant, applied to cracked clay tiles after thorough cleaning. Our trucks carry DuraFlex liner components for the relining jobs that aging Corte Madera chimneys eventually need. These are the brands specified by technicians who plan to stand behind their work for decades, not until the check clears.
Common Chimney Cleaning & Sweep Problems We See in Corte Madera Homes
- Seized damper assemblies from bay salt corrosion. In the flatlands east of US-101, we regularly extract dampers that are nearly welded shut with rust. The same-aged homes a mile uphill toward Ring Mountain show dampers that still function. Salt corrosion, not age alone, is the determining failure mode here.
- Cracked clay flue tile liners in 50-70-year-old ranch homes. Decades of marine moisture cycling expand and contract the masonry, opening cracks that let combustion gases leak into wall cavities. A standard sweep won’t fix this - HeatShield repair or relining is required.
- Galvanized flashing rusted through from persistent marine moisture. Bayfront homes lose flashing integrity faster than inland Marin properties. Crown leaks follow, compromising the masonry below. We repoint before we clean when this condition is active.
- Uneven creosote glazing from “Spare the Air” burn restrictions. The sporadic, intense burning pattern concentrates heavy deposits in chimney bends. Standard brushes skate over this glazing. Manual scraping with specialized tools is necessary to restore safe draft.

FAQs - Chimney Cleaning & Sweep in Corte Madera
Yes. We specialize in the post-WWII ranch homes between US-101 and the shoreline, and our trucks carry the heavy-duty extraction tools needed for salt-corroded components common to these properties. Call (855) 408-5567 to schedule - estimates are free.
Salt-laden marine air accelerates rust on cast-iron dampers and galvanized flashing far beyond what you’d see inland, often seizing dampers solid and rusting through flashing in 15-20 years rather than 40+. We inspect for this corrosion during every sweep and replace failed components with stainless-steel units in the same visit when possible.
Not always. The sporadic, intense burning pattern creates hardened, glazed creosote in chimney bends that resists standard rotary brushes. We assess this during inspection and use manual scraping tools where needed. If your flue has significant glazing, we’ll tell you before we start and quote the additional time required.
We can apply HeatShield refractory sealant to cracked clay tiles in the same visit, provided the damage is accessible and the chimney is otherwise sound. More extensive liner failure requires a separate relining appointment. We document the condition with camera photos during your Level 2 inspection and give you a plain-English verdict on whether repair or replacement is appropriate.
Your bayfront position exposes metal components to near-constant salt air that inland homes near Ring Mountain simply don’t receive. We’ve seen 50-year-old dampers on hillside homes still functional while identical units on San Clemente Drive are seized solid. Geography, not maintenance habits, is the difference. We replace with corrosion-resistant materials designed for this exact environment.
