Why Hearthstone Chimney Co. of San Francisco Is Kensington’s Preferred Chimney Cap & Crown Company

We’ve served Kensington and surrounding East Bay communities for over 42 years, since 1984. That longevity matters here. Homeowners in this ZIP 94530 enclave don’t want a fly-by-night operator who won’t answer the phone next season. They want a company that plans to be in town thirty years from now, because chimney work on these older homes is never truly finished.

Our reputation in Kensington is built on repeat calls and neighbor-to-neighbor referrals. We’ve replaced crowns on Santa Clara Avenue, installed custom caps above Colusa Circle, and coated spalling concrete on Portola Avenue homes where the southwest face had deteriorated two full cycles ahead of the sheltered northeast side. Customers remember that we document everything, explain what we’re seeing in plain terms, and put our 90-Day Done Right Promise in writing with no arguing.

Response time to Kensington is typically same-day or next-day. Our technicians are background-checked, uniformed, and carry professional-grade materials from Gelco, Olympia Chimney, and Famco on every truck. Most jobs are completed in a single visit. No-hassle upfront pricing means the number on your estimate is the number on your invoice. Done right, and we stand behind it.

Our Chimney Cap & Crown Services in Kensington

Crown Repair

Crown repair is our most frequent call in Kensington, and for specific reasons. The old lime-based mortar crowns on 1920s-1950s chimneys here weren’t designed to withstand decades of marine-layer moisture cycling. We rebuild deteriorated crowns with proper concrete mixes, install drip edges to shed water away from the brick, and slope the surface so fog condensation runs off rather than soaking in. On a 1937 Colonial Revival near Arlington Avenue last spring, we removed a crown that had cracked clean through from freeze-thaw damage after water had been wicking in for three winters unseen.

Crown Coating

For crowns with surface spalling but sound structural integrity, crown coating extends service life five to ten years at roughly half the cost of full rebuild. We use flexible, breathable coatings that seal hairline cracks without trapping moisture, critical in Kensington’s damp climate where vapor drive is constant. This is often our recommendation for homeowners who want to defer major masonry work without risking accelerated deterioration. The coating goes on in a single visit, cures within 24 hours, and carries the same 90-Day Done Right Promise as our full rebuilds.

Custom Cap Fabrication & Installation

Kensington’s varied rooflines and multiple-flue chimneys demand more than box-store solutions. We fabricate custom caps from stainless steel and copper to fit chimneys that never matched standard dimensions, especially on Tudor Revivals with decorative chimney pots or Craftsman bungalows with offset flues. A proper custom cap prevents the rain and debris intrusion that saturates crowns and flue walls, and we size the mesh to keep Berkeley Hills wildlife out while maintaining adequate draft. We replaced a cracked concrete crown on a 1929 Tudor Revival on Santa Clara Avenue that had Bay-facing mortar joints eroded three cycles ahead of the lee side. We installed a Gelco multi-flue cap to prevent water intrusion and seal the crown with a flexible coating, matching the original roofline.

Cap Replacement

When an existing cap is rusted through, improperly sized, or missing entirely, we measure on-site and install a replacement that actually fits your flue configuration. Many Kensington homes still have original caps that were never upgraded, or worse, have “temporary” sheet-metal covers that blew off in the first winter storm. We anchor our replacements properly and verify draft performance before we leave. Most cap replacements in Kensington are completed in under two hours.

Trusted Brands We Service in Kensington

We work exclusively with professional-grade materials from industry-trusted brands. For Kensington’s demanding coastal environment, we specify Gelco stainless-steel caps for corrosion resistance, Olympia Chimney components for multi-flue configurations, and Famco hardware rated for marine exposure. We stock common sizes and configurations locally, so most Kensington customers aren’t waiting on special orders. When a custom fabrication is needed, our turnaround is typically 3-5 business days, not weeks. No builder-grade substitutes, no corner-cutting. The materials we use are the same ones we’d specify for our own homes.

Common Chimney Cap & Crown Problems We See in Kensington Homes

• Marine-layer moisture destroys old mortar crowns. Kensington’s position in the East Bay hills puts it squarely in the fog belt, where coastal moisture cycles through lime-based mortar joints repeatedly. Spalling, efflorescence, and crown deterioration progress noticeably faster here than in the flatlands of El Cerrito or Richmond below.
• Southwest-facing chimneys erode asymmetrically. Many Kensington homes have exterior chimneys on southwest walls that take the full brunt of prevailing onshore winds. Technicians working this neighborhood inspect the Bay-facing mortar face first, where erosion often runs two or three repointing cycles ahead of the sheltered side, even on chimneys that look fine from the street.
• Unlined flues allow direct water intrusion. Original clay-tile or unlined flue openings in Kensington’s pre-1950s chimneys lack modern protection. Rain and debris enter freely, saturate the crown and flue walls, and create freeze-thaw damage during cold snaps that would be minor inconveniences on properly capped systems.
• Salt-laden fog corrodes metal components prematurely. The same fog that wicks into masonry carries enough salt to accelerate corrosion of galvanized caps, spark arrestors, and fasteners. We see metal failures here five to seven years ahead of inland counterparts.
