Call (844) 803-1545

We’ve been answering calls from Claremont homeowners since 1984, and our technicians know the difference between a Village-area Craftsman chimney built in 1926 and a mid-century ranch flue off Foothill Boulevard. Russell Haines and our team at Hearthstone Chimney Co. respond to Claremont calls seven days a week, with live phone answering at (844) 803-1545 every hour of every day. Most repairs are scheduled within 48 hours, and we carry the professional-grade materials to finish the job without ordering parts.

Claremont’s position at the base of the San Gabriel Mountains creates real chimney stresses you won’t find in flatland cities. The elevation here, roughly 1,169 feet, produces cooler evenings that extend the wood-burning season well past what Ontario or Pomona residents experience. More burns per year means more creosote, more thermal cycling, and more mortar fatigue. Meanwhile, those celebrated sycamores and liquidambars that give Claremont its “City of Trees” identity shed debris directly into uncapped flues, accelerating deterioration from the inside out. Our Chimney Repair team documents every inspection with photos you’ll see and a plain-English verdict you’ll understand.

Why Hearthstone Chimney Co. Is Claremont’s Preferred Chimney Repair Company

Forty-two years in this region means we’ve repaired chimneys on homes near the Claremont Colleges that were built before World War II, and we’ve replaced crowns on ranch houses off Towne Avenue that went up during the Johnson administration. That continuity matters to Claremont homeowners, many of whom have lived in the same house for twenty or thirty years and intend to stay.

Our Level-2 camera inspections end with photographs you can examine yourself and a written verdict without jargon. No surprises on the bill, either - we quote upfront, and the number on the estimate matches the number on the invoice. Background-checked, uniformed technicians arrive when we say they will, complete most repairs in one visit, and leave the work site clean.

The 90-Day Done Right Promise governs every job: if it’s not right, we come back and make it right, in writing, no arguing. That’s the Keystone Standard - Krafted right, Every time, Your home first, Standing behind it. And when you call (844) 803-1545, a live person answers, 24 hours a day, 7 days a week. Not a callback queue. Not an app.

Our Chimney Repair Services in Claremont

Mortar Repointing

The freeze-thaw cycles at Claremont’s elevation, modest but real on winter nights, grind away at mortar joints between bricks. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade masonry cement formulated for Southern California’s dry-wet seasonal pattern. Homes north of Base Line Road, especially those with original 1920s-1940s masonry, frequently need selective repointing before full rebuilds become necessary. Done right, repointing adds decades to a chimney’s life.

Spalling Brick Repair

Spalling - bricks flaking and crumbling from moisture trapped inside - is especially common in Claremont’s older unlined chimneys where decades of combustion gases have degraded the interior masonry. The mountain-facing exposure on north and east slopes accelerates the damage. We remove spalled bricks, assess the underlying structure with our camera system, and replace with matching brick where possible or recommend partial rebuild when the stack has compromised integrity. Every spalling repair includes a written evaluation of whether waterproofing or a new liner would prevent recurrence.

Chimney Waterproofing

Claremont’s Santa Ana wind events drive rain horizontally into porous masonry, and the dry spells between allow moisture to migrate deep into brick before evaporating, leaving salt deposits that expand and crack the surface. We apply vapor-permeable waterproofing agents from professional-grade manufacturers that allow the chimney to breathe while repelling liquid water. This is particularly valuable for homes in the Padua Hills area and other northern neighborhoods where wind exposure is strongest. Waterproofing is never a substitute for proper crown and flashing condition, and we’ll tell you straight if your money is better spent there first.

Flashing Repair

The junction between chimney and roof is where most Claremont homeowners first notice a problem - a water stain on the ceiling, peeling paint, or a musty smell after rare heavy rains. We remove compromised flashing, inspect the underlying roof deck and sheathing for hidden rot, and install new step flashing and counterflashing with proper overlap and sealant. Our technicians carry copper and galvanized steel flashing stock sized for the varied roof pitches found in Claremont’s mixed housing stock, from low-slope ranch additions to steep gables on Village-area revivals.

We also handle Chimney Cap & Crown in Claremont for homeowners whose deterioration starts at the top, and our Fireplace Services in Claremont cover damper repair, firebox rebuilding, and insert installation for the same homes we repair chimneys on.

Trusted Brands We Service in Claremont

Our trucks carry professional-grade materials from DuraFlex, HeatShield, and Famco - no builder-grade substitutes that fail in three seasons. For Claremont homeowners, that means we can often complete a liner repair with DuraFlex stainless steel or a crown rebuild with HeatShield’s engineered refractory compound on the same day we diagnose the problem. We don’t have to order parts and make you wait. When a historic home near the Colleges needs a custom solution, Copperfield’s specialty fittings and Olympia Chimney’s accessory line give us options that respect the original architecture while meeting current safety standards. Every brand we use is chosen for how it performs in real Southern California conditions, not how it looks in a catalog.

Common Chimney Repair Problems We See in Claremont Homes

• Deteriorated clay-tile flues in pre-1960 homes. Many Craftsman and Period Revival chimneys near the Village and Claremont Colleges were built with unlined masonry or single-wall clay tiles that have cracked from decades of thermal shock. Our camera inspection reveals the damage without dismantling the stack, and we can often install a DuraFlex stainless liner without major reconstruction.
• Cracked mortar crowns on mid-century ranch homes. The south and east sides of Claremont are filled with 1950s-1970s ranches whose concrete crowns have shrunk, cracked, or washed out, letting water straight into the chimney core. We pour new crowns with proper drip edges and slope, or apply HeatShield CrownCoat for sound substrates with minor cracking.
• Wind-driven debris accumulation from Claremont’s dense tree canopy. Those mature sycamores and jacarandas that make the city beautiful also drop leaves, twigs, and seed pods into open flues, blocking draft paths and holding moisture against interior masonry. A proper cap installation, which we handle as part of our repair workflow, prevents this entirely.
• Code-compliance gaps in High Fire Hazard Severity Zone properties. Northern Claremont neighborhoods bordering Claremont Hills Wilderness Park fall within California’s designated high-risk zone, where functional spark arrestors and documented recent inspections are increasingly required by insurers. We repair to code, document with photos, and provide written certification you can forward to your carrier.
