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 Repair Across Corte Madera
Chimney repair in Corte Madera usually means one of three things: a cracked crown letting water into the masonry, a rusted damper that won’t open or close, or a flue blocked by pine needles and animal nests. Our crews work throughout Corte Madera, from the Madera Gardens flats up to Chapman Park, and we’re familiar with how the bay air and tule fog behave here. Call (830) 251-4560 for a written estimate before any work starts. You’ll get a flat price, a camera inspection with photo report, and a repair guaranteed in writing for one full year.
Why Flint Chimney Sweep Is Corte Madera’s Preferred Chimney Repair Company
Since 2002, Flint Chimney Sweep has operated under The Garrison Standard, a code shared by every Garrison Partners location. That standard is simple: written price before work, background-checked technicians in uniform, and a 365-Day Done Right Promise on every repair. Corte Madera homeowners call us because they’ve been burned before by chimney companies that no-show, move the price at the door, or leave a mess behind. We don’t do any of that.
The 365-Day Done Right Promise is a written guarantee. If a covered repair fails within one full year of the service date, we return at no charge. No argument, no re-quote. It’s part of the invoice you’ll sign before we start. Hank Delano leads our team, and he’s particular about one thing above all: the number on the invoice is the number you approved. Always.
Response time to Corte Madera is straightforward. Dispatch is coordinated from our San Francisco Bay Area office, and crews serve Corte Madera locally. When you call, a live person answers. Not a voicemail tree, not a callback form. We’ll give you a window, show up inside it, and finish the job without leaving a mess behind.
Chimney Cap Installation in Corte Madera
Chimney Cap Installation in Corte Madera is one of the most common repairs we book, and for good reason. An uncapped flue is an open invitation to the birds, squirrels, and pine needles that Corte Madera’s tree-heavy lots produce year-round. We measure the flue, specify the right cap from a professional-grade line like Gelco or Olympia Chimney, set it in place, and confirm the draft with a camera. A cap installation in Corte Madera typically runs $325 – $550, depending on flue size and cap material.
What We Install
We specify caps by job, not by margin. That means a simple single-flue stainless cap when that’s all you need, or a Gelco multi-flue cap when the chimney serves more than one appliance. Every cap goes on with mechanical fasteners appropriate for Corte Madera’s salt air, which eats cheap galvanized hardware faster than you’d think.
Why Capping Matters Here
In the Chapman Park and Madera Gardens flats especially, marine fog keeps masonry damp for weeks at a time. A capped flue stays dry; an open flue absorbs moisture that softens the crown and the top courses of brick. The cap is a small repair that prevents a much larger one.
Chimney Cap Replacement in Corte Madera
Chimney Cap Replacement in Corte Madera usually means the old cap rusted through, blew off in a winter storm, or was installed wrong in the first place. We see a lot of aftermarket caps from big-box stores that never fit right in the first place. A replacement cap in Corte Madera typically runs $275 – $475, including removal of the old unit and fastener replacement.
Signs the Cap Has Failed
Water staining on the ceiling near the flue, rust flakes in the firebox, or a damp smell around the chimney are all signs. If the cap is loose enough to rattle in the wind, it’s already done. We’ll replace it with a cap that’s sized to the flue, not a universal fit that wobbles.
Materials We Use
We carry local stock of Olympia Chimney and Gelco caps for fast turnaround in Corte Madera. Stainless steel is standard for this climate; painted steel doesn’t survive the salt air here, and we’d rather not sell you something that fails in three years. Our Chimney Repair team will show you the old cap and the new one before we install anything.
Trusted Brands We Service in Corte Madera
Flint Chimney Sweep works with professional-grade chimney materials, and we name them so you can verify quality independently. On Corte Madera jobs, you’ll most often see DuraFlex for flue relining, HeatShield for resurfacing deteriorated flue walls, and Gelco or Olympia Chimney for caps. Famco and Copperfield hardware show up when a project calls for specific dampers or chase covers. We keep common components stocked for Corte Madera customers, which means faster turnaround on most repairs. Nothing gets installed unless it’s specified for the job, and you’ll see the brand name on the written estimate.
Common Chimney Repair Problems We See in Corte Madera Homes
- Damp masonry and spalling brick. Winter tule fog and salt air off San Francisco Bay keep chimney masonry wet for stretches at a time. Over years, this softens mortar joints, pops brick faces, and widens cracks in the crown. The chimney looks fine from the ground; it isn’t.
- Nests and debris in uncapped flues. Eucalyptus and pine trees line many Corte Madera lots. Birds and squirrels drop debris down open flues, and the resulting blockage kills draft and pushes smoke back into the house. We’ve pulled entire nests out of flues in Madera Gardens.
- Rusted dampers and cracked crowns. Salt air corrodes dampers faster here than inland. A damper that won’t close lets warm air out and rain in. A cracked crown lets water run down between the flue and masonry. Both problems usually surface as a smoky firebox or water stain, not as an obvious chimney failure.
- Flashing leaks where chimney meets roof. The wind off the bay works sheet metal over time. Flashing that looked fine five years ago starts to separate at the seams, and the first clue is a ceiling stain two feet from the fireplace.

FAQs About Chimney Repair in Corte Madera
Not necessarily every year. If you burn fewer than a dozen fires a year, a Level 1 inspection every other year is usually sufficient in Corte Madera, unless you’ve seen signs of water, animals, or smoke rollout. The bigger risk here is not creosote buildup; it’s moisture and nesting. We’ll give you a straight answer after one look.
First-degree creosote is a loose, brushable soot; third-degree is a hard, glossy tar that will not come off with a standard sweep and can fuel a chimney fire. In Corte Madera, we see less third-degree creosote than colder inland climates because the marine air keeps flue temperatures lower, but that same moisture creates damp, sticky creosote that clings to flue walls. It matters. A camera inspection tells you which you have.
Yes. A standard chimney sweep in the Corte Madera area runs $190 – $260, and a Level 2 inspection with camera runs $240 – $350. If a repair is needed, we put the exact price in writing before any work starts. The number you approve is the number on the invoice. Call (830) 251-4560 for a written estimate.
Two reasons: the tree canopy and the climate. Eucalyptus and pine trees tower over many Corte Madera homes, and birds and squirrels nest in them year-round. Open flues under those trees fill with pine needles, eucalyptus debris, and nest material quickly. A properly fitted cap ends the problem, and we install them frequently in Madera Gardens and Chapman Park.
We don’t promise same-day dispatch. What we do is book a hard appointment window and show up inside it, with a live person on the phone if anything changes. Chimney repair in Corte Madera is urgent when there’s active water intrusion or smoke rollout; if that’s your situation, call (830) 251-4560 and we’ll get you on the schedule as fast as our Corte Madera route allows.
