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.
Fast, Reliable Chimney Inspection Across Corte Madera
A chimney inspection in Corte Madera typically runs $189 – $589 depending on the level, and most homeowners book one because they haven’t looked up the flue since they bought the house. Corte Madera’s flatland neighborhoods sit hard against the marsh, and the salt-laden marine air works on damper plates, flashing, and liner components year-round, whether you burn or not. Our crews know exactly what to look for in the post-war ranch tracts east of 101, and we’ll show you camera footage before we recommend a single repair. If it’s time for a cleaning, you can book our Chimney Sweep in Corte Madera. Call (336) 863-3889 and talk to a real person, not a voicemail tree.
Ruben Castellano has run Alcott Chimney Sweep since 2002. Every inspection includes a written report, a written price before any work starts, and a 365-Day Done Right Promise on anything we repair. That’s the whole point: certainty before the truck pulls up, evidence before you spend a dime.
Why Alcott Chimney Sweep Is Corte Madera’s Preferred Chimney Inspection Company
We’re not the cheapest shop in Marin, and we don’t try to be. We’re the one that sends you a name and a photo before the technician arrives, so you know exactly who’s walking up your driveway. Every Alcott tech passes a background check and identity verification under the Threshold Standard before they ever step on a Corte Madera property. They wear a uniform, they carry a photo ID badge, and they show it at the door. No exceptions.
Corte Madera homeowners tell us the same thing, year after year: they put off the inspection because they didn’t want to be sold a liner they couldn’t verify. That’s why we show you the camera screen in real time. If a repair can safely wait, we say so plainly. If something is failing, you see it yourself before any recommendation leaves our mouth. Ruben built the company on that habit: show the work, then let the evidence do the talking.
We coordinate dispatch from our Bay Area office, and crews serve Corte Madera locally. Response time for a standard inspection here is usually a few days, not a few weeks. For a rusted-shut damper or a suspected leak, call (336) 863-3889 and we’ll get you on the schedule fast.
Level 2 Chimney Inspection in Corte Madera
A Level 2 Chimney Inspection in Corte Madera is what we recommend for any fireplace that’s been sitting idle through two or three Spare the Air seasons, and it’s the standard for real estate transactions, appliance changes, or a chimney that’s taken on water. It costs $289 – $589 here. The job includes everything in a Level 1, plus a full interior camera scan of the flue, accessible attic and crawlspace checks, and an exterior assessment of the crown, flashing, and clearance from combustibles.
In Corte Madera, this level matters more than in inland Marin. The salt air off the marsh corrodes what you can’t see, and camera footage is the only way to confirm what’s actually happening inside a 60-year-old clay tile liner.
Camera evidence, not opinion
You watch the screen while we scope. If there’s first-degree creosote condensation, hairline mortar spalling, or a damper plate rusted solid, you’ll see it in real time. We don’t ask you to take our word for any of it.
When to book one
Buying or selling a home here? A Level 2 is the accepted standard for real estate inspections in Corte Madera. Also book one if you’ve changed appliances, switched from wood to gas, or haven’t burned in multiple seasons and want to know the flue is still safe to use.
Chimney Leak in Corte Madera
A chimney leak in Corte Madera usually traces back to the crown, the flashing, or the masonry itself, and in this town the salt air accelerates all three. A leak diagnosis with a camera inspection runs $189 – $489, depending on how far we need to trace it. Water stains on the ceiling near the fireplace are the classic tell, but by the time you see those, the damage has usually been working for a while.
What makes Corte Madera different is the moisture cycle: bay fog rolls in most mornings, condenses on the crown, seeps into old mortar joints, then the afternoon sun bakes it back out. Fifty-plus years of that cycle spalls joints around the firebox and the chimney crown. The leak you’re chasing today probably started as a hairline crack five years ago.
What we check first
Crown condition, flashing seal, and the top course of flue tile. In east-of-101 homes near the mosaic of streets off Tamalpais Drive, we routinely find flashing that’s lifted and crowns that have turned porous from salt exposure. We’ll show you the exact spot on camera before quoting a fix.
Does the whole chimney need rebuilding?
Rarely. Most leaks respond to crown sealing, flashing repair, and tuckpointing the worst joints. We give you a written price for exactly what the camera showed, and nothing else. If a repair fails within the coverage period, the second visit is free. That’s written, not verbal.
Trusted Brands We Service in Corte Madera
We stock and install the same trade brands Corte Madera’s chimney professionals specify, not box-store substitutes. That means DuraFlex liner systems when a flue is beyond resurfacing, HeatShield when the clay tile can be restored, and Famco and Copperfield caps and dampers for the salt-heavy air near the marsh. Having parts on hand speeds things up for our Corte Madera customers because we’re not waiting on a shipment from a warehouse three states away. If a Famco damper plate has rusted out on your 60s ranch, we can usually replace it same-day and show you the old part before it goes in the truck.
Common Chimney Inspection Problems We See in Corte Madera Homes
- Rusted-shut damper plates. In homes east of 101 near the Corte Madera Marsh, salt air works on damper hardware constantly. After two or three Spare the Air winters with no fire, homeowners discover the damper won’t open at all, and they had no idea anything was wrong until we scoped it.
- Hairline mortar deterioration. The post-WWII ranch-style tracts that dominate the flatland neighborhoods have original masonry fireplaces now 50 – 60 years old. Bay fog condenses on the crown every morning, soaks into the joints, and spalls them over decades. We catch it before the firebox starts dropping brick.
- First-degree creosote condensation. This is the tar-like buildup that causes chimney fires. In Corte Madera, we see it accumulate even without regular burning because the coastal fog cycling through an unused stack creates the exact conditions creosote needs to condense inside the flue tile.
- Wildlife nesting in idle flues. Long stretches of burn bans leave flues cold and quiet. Birds and small animals move in. We find nests, debris, and the occasional raccoon surprise during inspections on homes near the open space corridors between Larkspur and the marsh.
Pricing for Chimney Inspection in Corte Madera, CA
A Level 1 visual inspection in Corte Madera runs $189 – $249. A Level 2 camera inspection runs $289 – $589. A Level 3, where we open up masonry or liner material to reach hidden areas, starts around $1,000 and is only recommended when Levels 1 and 2 show something that demands a closer look. What moves the price is access, height, and what we’re scoping: a single-story ranch on a slab off Eastman Way is a different job than a two-story with a steep roof near Christmas Tree Hill.

FAQs About Chimney Inspection in Corte Madera
Yes, and in Corte Madera that’s exactly when you need one most. The salt air doesn’t stop working because the fireplace is cold. Dampers rust, mortar absorbs fog, and creosote condenses inside idle flue tiles. We’ve pulled enough rusted damper plates out of marsh-adjacent homes to tell you: the seasons you skipped are the seasons the chimney quietly deteriorated. Call (336) 863-3889 and book a Level 2 so you can see the condition for yourself.
Because Corte Madera’s flatland neighborhoods sit immediately against the marsh and open bay, so the marine air carries more salt, more consistently, than inland towns. That salt-laden air attacks damper plates, flashing, and metal liner components year-round. San Rafael and Novato are set back far enough that the corrosive load is lighter and the damage takes longer. Here, it’s not unusual to find hardware completely seized shut after a few years of light use.
A Level 2 includes everything in a Level 1 inspection, plus a full interior camera scan of the flue, accessible attic and crawlspace access points, and a close exterior evaluation of the crown, flashing, and clearances. And yes, you watch the screen while we scope. If the flue tile is spalling or the damper is rusted solid, you’ll see it in real time, not in a report you have to trust. Nothing is recommended without evidence you’ve seen yourself.
Almost certainly, and in Corte Madera it’s the number-one thing we find in east-of-101 homes near the marsh. Salt air rusts the damper plate shut over a few idle seasons, so even when you open the lever, the plate doesn’t move. That cuts off draft, and the fireplace either won’t light or fills the room with smoke. It’s a straightforward fix with a replacement plate, and you’ll see the old corroded part before it’s removed.
First-degree creosote is a fine, flaky, tar-like deposit that forms inside the flue when combustion gases cool too quickly. In Corte Madera, the bay fog cycling through an unused stack creates the same cooling effect even without a fire, so we see first-degree creosote in flues that haven’t been lit in two or three seasons. It’s flammable, and if enough of it builds up, one cold-weather fire can turn into a chimney fire. That’s why a Level 2 inspection before the burn season matters here, not just an annual sweep.
