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.

AfterChimney Company in Corte Madera, CA
Alcott Chimney Sweep handles chimney cleaning, inspection, and gas fireplace repair in Corte Madera, CA. The homes here present a very specific set of conditions: post-WWII and 1960s – 70s ranch-style tract houses on the flatlands sit directly beside the Corte Madera Marsh and open bay, where salt-laden marine air corrodes dampers, flashing, and metal liner components faster than almost anywhere else in Marin County. Add in winter Spare the Air burn bans that keep fireplaces dark for months at a time, and you get chimneys that silently deteriorate while nobody is watching. Call (336) 863-3889 and you’ll get a live person, a straight answer, and a written price before any work starts.
Why Corte Madera Homes Are Different
Corte Madera sits in a terrain corridor between Marin’s coastal hills and the bay. Onshore winds funnel straight through town, driving salt-heavy air into and around chimney crowns, caps, and masonry. The moisture-salt combination does two things you won’t see to the same degree in San Rafael or Novato: it accelerates metal corrosion and it promotes creosote condensation inside flue tiles. Technicians working the east-of-101 neighborhoods near the marsh regularly find damper plates that have rusted completely shut. Homeowners assume the fireplace is fine because Spare the Air days kept them from lighting it for two or three consecutive seasons, never realizing the salt air has been working on the hardware the entire time.
The housing stock compounds the problem. Most bay-side Corte Madera homes were built with original masonry fireplaces and mortar joints now 50 to 60 years old. Constant moisture cycling from bay fog pushes hairline mortar deterioration, which lets water into places water should not go. That water then attacks the metal damper assembly, the flashing, and any liner components. By the time a homeowner schedules the first sweep in years, we’re often looking at more than just soot.
Flatter, east-side neighborhoods are more exposed than the hillside streets to the west, simply because the marsh and open water sit right there. Morning and evening fog rolls in, condenses on chimney crowns, and seeps into the masonry. Homes nearer the waterline tend to show more rust and more mortar loss than homes just a few blocks uphill. This is local knowledge that matters when deciding what to inspect, what to clean, and what to leave alone until the next visit.
Wildlife adds another layer. The marsh attracts birds, raccoons, and squirrels, and an unused flue capped with a rusted-out damper is an invitation. Debris and nests mixed with years of stale creosote is a common finding on the first visit to a Corte Madera chimney.
Our Main Corte Madera Services
The two services Corte Madera homeowners call about most are chimney sweeping and chimney inspection, though gas fireplace repair picks up sharply every fall. Each has its own dedicated Corte Madera page.
Chimney Sweep in Corte Madera
A proper sweep removes creosote, the tar-like byproduct of burning wood that builds up inside the flue and is the leading cause of chimney fires. In Corte Madera, creosote often sits for multiple seasons because burn bans kept the fireplace idle, giving it time to thicken and harden. Wind-driven salt air then adds condensation that makes the creosote stickier and harder to remove than typical inland deposits. We clean the full system, not just the visible firebox, and we tell you exactly what we found afterward. See the full breakdown on our Chimney Sweep in Corte Madera page.
Chimney Inspection in Corte Madera
An inspection here is not a formality. It’s a hunt for salt-air corrosion, mortar loss, and wildlife entry, all of which are common in east-side neighborhoods near the marsh. We use a camera so you can see what we see, plain as day. When we recommend a repair, we hand you photo evidence, not a vague warning. Inspections are especially worth doing after a long stretch of Spare the Air days, because a chimney that has not been lit in two or three seasons may have serious problems hiding behind a closed damper. Details are on our Chimney Inspection in Corte Madera page.
Gas Fireplace Repair in Corte Madera
Gas fireplaces have their own failure pattern in this marine climate: pilot assemblies corrode, thermocouples wear out, and glass seals fog from constant moisture. Homeowners in marsh-adjacent neighborhoods bring us gas fireplaces that work fine for eight months and then refuse to light the first cold evening of fall. We diagnose before we replace, show you what failed, and quote a written price before touching a single component. Full service detail is on our Gas Fireplace Repair in Corte Madera page.
