We know the post-war ranch homes between US-101 and the bay, the hillside places near Ring Mountain, and the specific problems that salt-laden marine air causes for masonry and metal components.

Why Hearthstone Chimney Co. of San Francisco Is Corte Madera’s Preferred Chimney Repair Company
Warren Eckhart founded this company in 1984, and we’ve spent over 42 years building a reputation in Marin County by doing the thing correctly and standing behind it. Corte Madera homeowners call us because we document every inspection with a Level-2 camera, explain the verdict in plain English, and put our 90-Day Done Right Promise in writing with no arguing.
Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like Gelco, Olympia Chimney, and Famco on every truck. That means most repairs in Corte Madera are finished the same day we arrive. No callback queues. No waiting on parts from a warehouse across the state.
We also understand the local burn restrictions. Bay Area Air Quality Management District ‘Spare the Air’ days concentrate wood-burning into narrow windows, which creates uneven creosote patterns we see nowhere else. A sweep who treats your chimney like it’s in Sacramento will miss what we catch.
Our Chimney Repair Services in Corte Madera
Mortar Repointing
The ranch-style homes built across Corte Madera’s flatlands from the 1950s through the 1970s are now 50-70 years old. Their mortar joints have endured decades of marine moisture, thermal cycling from intermittent burns, and the salt air that blows in off the bay. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade masonry cement formulated for coastal exposure. Done right, repointing adds decades of service life without the cost of rebuilding.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is accelerated in Corte Madera by a specific sequence. Salt air and winter rains (November through March) drive moisture into hairline cracks. Freeze-thaw cycles are rare here, but the constant wet-dry cycling does similar damage. We remove spalled brick where necessary, install matching replacements, and apply breathable waterproofing to stop the cycle. In hillside homes near Ring Mountain, where exposure differs, we adjust our material selection accordingly.
Chimney Waterproofing
Waterproofing a Corte Madera chimney requires a vapor-permeable sealant that lets moisture escape while blocking new water entry. We use professional-grade formulations from Copperfield and Olympia Chimney, applied after all cracks and spalls are addressed. For flatland homes closest to the bay, we often recommend crown sealing and cap replacement as part of the same job, since the salt air attacks multiple components simultaneously.
Flashing Repair
Galvanized flashing in Corte Madera’s 94925 zip corrodes faster than inland Marin. We replace failed flashing with copper or stainless steel where appropriate, and we inspect the surrounding roof deck for hidden water damage. Our technicians document the condition with photos before and after, so you see exactly what was addressed.
Chimney Rebuilding
When mortar joints, spalling, and liner damage converge in a 60-year-old chimney, partial or full rebuilding from the roofline up may be the square deal. We rebuild with matching brick, proper crown construction, and new clay or stainless steel liners as needed. Every rebuild carries our 90-Day Done Right Promise in writing.
Tuckpointing
For chimneys where the mortar is sound but the aesthetic needs restoration, or where early-stage deterioration requires precise intervention, tuckpointing fills and finishes joints with matched color and profile. It’s a craftsman’s repair, and we treat it that way.

Trusted Brands We Service in Corte Madera
We stock professional-grade materials from Famco, Gelco, and Olympia Chimney on our service trucks, which means Corte Madera homeowners aren’t waiting for parts to ship from a distant warehouse. Famco dampers stand up to salt air better than the builder-grade units we pull out of flatland homes. Gelco caps and Olympia Chimney liner components are engineered for coastal conditions. When we specify a material, it’s because we’ve watched it perform in this specific environment.
Common Chimney Repair Problems We See in Corte Madera Homes
- Salt corrosion seizing cast-iron dampers. In the flatlands between US-101 and the bay, we regularly remove damper assemblies that are nearly welded shut from 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.
- Spalled brick crowns from moisture intrusion. Winter rains exploit cracks accelerated by bay air exposure, expanding spalls and compromising crown integrity before homeowners notice water stains on the ceiling.
- Clay flue tile cracking in 50-70 year old ranch homes. Original clay liners in Corte Madera’s post-war housing stock crack from thermal shock and settling. We evaluate whether repointing and relining will suffice, or if the damage warrants rebuilding.
- Uneven creosote accumulation from ‘Spare the Air’ burning patterns. Concentrated burning during approved windows creates hot, heavy fires that deposit creosote differently than steady winter use. This demands targeted cleaning and more frequent inspection of flue condition.

FAQs - Chimney Repair in Corte Madera
Your home’s proximity to the bay exposes it to salt-laden marine air that corrodes cast iron and galvanized steel far faster than the inland conditions in San Anselmo or Fairfax. We responded to a call in the flatlands near San Clemente Drive where an original 1960s damper was rusted solid from decades of salt air exposure. We removed and replaced it with a new Famco damper, then repointed the clay flue liner joints that had cracked due to moisture intrusion from the bay. If your damper is sticking or your flashing is showing orange streaks, call (855) 408-5567 for an inspection - estimates are free.
It depends on crack pattern, location, and whether the surrounding mortar joints are still sound. Hairline cracks confined to a few tiles can sometimes be addressed with HeatShield resurfacing or targeted repointing. Multiple through-body cracks, shifted tiles, or gaps at the mortar joints usually mean a stainless steel liner from Olympia Chimney is the correct long-term solution. We document the condition with camera photos and give you a plain-English verdict. Call (855) 408-5567 for a Level-2 inspection.
Yes, because concentrated burning during narrow approved windows creates hotter, less controlled fires that deposit creosote unevenly and stress clay flue tiles with thermal shock. A chimney used for steady weekend burns all winter behaves differently than one fired intensively on scattered ‘no-burn’ exceptions. We adjust our inspection and cleaning recommendations for Corte Madera homeowners based on your actual burn pattern, not a generic calendar schedule. Call (855) 408-5567 to discuss your usage.
A three-part approach: repair all cracks and spalls first, apply a vapor-permeable waterproofing sealant formulated for coastal masonry, and ensure your crown and cap are intact with proper overhang. For flatland homes in 94925, we often specify enhanced crown construction because the salt air attacks cap, damper, and crown as a system. Call (855) 408-5567 for a condition assessment and written estimate.
We recommend rebuilding when repointing and localized repair would exceed roughly 60% of rebuild cost, or when the liner, crown, and multiple wall courses are all compromised. A 70-year-old chimney in Corte Madera with original clay liner, spalled crown, and deteriorated mortar is often at that threshold. We give you both numbers - repair scope and rebuild scope - so you decide with full information. Either way, it’s covered by our 90-Day Done Right Promise in writing. Call (855) 408-5567.
