Why Hearthstone Chimney Co. of San Francisco Is Cherryland’s Preferred Chimney Cap & Crown Company
Warren Eckhart founded this company in 1984 with a simple standard: do the job right, explain it plainly, and stand behind it. That standard hasn’t changed. In Cherryland, that means understanding what 60 to 80 years of Hayward Fault micro-movements do to unreinforced masonry chimneys - knowledge that Cherryland Chimney Cleaning & Sweep specialists need, but out-of-area sweeps often lack.
Our technicians carry Gelco and Olympia Chimney caps on the truck, sized for the odd flue dimensions common in 1940s-1960s tract construction. Most our Fireplace Services in Cherryland jobs finish in a single visit. We document every inspection with photos you can see and a plain-English verdict - no jargon, no scare tactics.
The 90-Day Done Right Promise governs every job: in writing, no arguing. If it’s not right, we come back. We’ve operated this way for four decades because we plan to be serving Cherryland for decades more.
Our Chimney Cap & Crown Services in Cherryland
Custom Cap Fabrication & Installation
Cherryland’s older chimneys were built before standardized flue spacing became common. Two flues six inches apart, offset tile sizes, or corbeled brick that no off-the-shelf cap fits - we see it weekly. Our Chimney Cap & Crown team measures on-site and fabricates custom caps from stainless steel or copper, anchored with seismic-rated expansion bolts that accommodate fault-zone movement without tearing the crown. A custom cap in Cherryland typically runs $450-$780 installed.
Multi-Flue Cap Systems
Many Cherryland homes near the Hayward Fault trace have two or more flues sharing a single deteriorated crown. A multi-flue cap covers the entire assembly, eliminating the gaps where separate caps fail to meet. We size these from Famco and Copperfield stock, then bed them in Crown Coat silicone over a rebuilt or stabilized crown. Multi-flue installations in Cherryland generally cost $380-$650.
Crown Repair & Rebuild
The crown is the concrete or mortar wash that seals the chimney top. In Cherryland’s seismic environment, original crowns crack, spall, and separate from the brick beneath - exactly what we found near Kelly Street and Lewelling Boulevard on that 1950s tract home where decades of fault micro-movements had destroyed the steel crown. We remove loose material, patch with engineered crown mix, and apply a sloped finish that sheds water toward the drip edge - standard Chimney Repair in Cherryland. Full crown rebuilds run $480-$890; partial repairs with coating start around $280.
Crown Coating & Waterproofing
For crowns with minor cracking but sound structure, Crown Coat silicone sealer buys years of protection. This matters in Cherryland because our cool, foggy winters let moisture sit in hairline cracks, then freeze-thaw or seismic jostling opens them wider. Crown coating runs $280-$420 and takes a few hours, not days. We apply it only after confirming the crown substrate is stable - no point in sealing over hidden damage.

Trusted Brands We Service in Cherryland
We stock caps and crown materials from Gelco, Olympia Chimney, and Famco - brands that manufacture to professional-grade specs, not the thin-gauge hardware-store equivalents that rust through in three Cherryland winters. Because we carry inventory sized for the odd flue dimensions common in local 1940s-1960s construction, most Cherryland customers don’t wait for special orders. A rusted cap with birds nesting can be resolved today, not next week.
Common Chimney Cap & Crown Problems We See in Cherryland Homes
- Seismic crown cracking from Hayward Fault stress. Original 1940s-1960s masonry crowns weren’t built to flex. Decades of micro-movements along the fault trace create hairline fractures that widen each winter as fog moisture penetrates and freeze-thaw cycles work the gap. We inspect for this damage during every cap or crown service.
- Missing or failed caps letting marine fog condense inside flues. Cherryland’s persistent winter marine layer sends damp air straight down an open flue. Without a proper cap, that moisture attacks mortar joints from the inside, accelerating deterioration in unreinforced brick chimneys that already face seismic stress.
- Improper aftermarket caps rusting through. Past sweeps or handymen often installed universal caps that don’t fit Cherryland’s odd flue tile sizes. The gaps let water in; the wrong alloy rusts through in seasons. We measure before we quote and fabricate when stock won’t serve.
- Animal intrusion through corroded or displaced caps. Squirrels and birds find their way into deteriorated caps quickly in Cherryland’s residential neighborhoods. Once inside, nesting material blocks the flue and creates fire and carbon monoxide hazards. We replace the cap and inspect the flue for obstructions in the same visit.

FAQs - Chimney Cap & Crown in Cherryland
Yes, if the work involves structural modification or liner replacement, permits go through the Alameda County Building Department - not a city office - because Cherryland is unincorporated. Straight cap replacement on an existing sound crown usually does not trigger permitting. We handle the paperwork when permits are required and factor that into your timeline and cost. Call (855) 408-5567 for specifics on your job.
Cherryland sits directly on the Hayward Fault trace, and decades of cumulative seismic micro-movements crack and spall original unreinforced masonry crowns that were never engineered for this stress. Combined with cool, foggy winters that keep moisture in those cracks, failure accelerates faster than in cities further from the fault. Our inspections specifically look for fault-induced damage patterns.
Yes. Near the intersection of Kelly Street and Lewelling Boulevard, we replaced a rusted-out multi-flue cap on a 1950s tract home where the original steel crown had separated from the brick beneath - a direct result of decades of Hayward Fault micro-movements. We installed a custom copper Fabricated cap over both flues, anchored with expansion anchors to prevent the same failure, and applied a Crown Coat silicone sealer to the rebuilt crown. Two-flue custom caps in Cherryland typically run $520-$780.
Yes, if the crown beneath is sound. We remove the rusted cap, inspect the crown for cracks or separation, and install a properly sized replacement - stainless steel or copper, never another rust-prone unit. If inspection reveals crown damage, we’ll show you photos and explain before any additional work. Cap-only replacement in Cherryland runs $280-$420.
Annually, and immediately after any noticeable tremor. The combination of Hayward Fault seismic stress and Cherryland’s fog-driven moisture infiltration means crown damage can progress from hairline to hazardous faster than in less active zones. Our Level-2 camera inspections document crown condition with photos you can see. The $89 Seasonal Tune-Up includes this assessment.
