Fast, Reliable Chimney Repair Across Calabasas
Chimney repair in Calabasas typically runs $180 to $4,500 depending on scope, and our Chimney Repair team completes most jobs in a single visit with upfront pricing confirmed before we start. We’ve been driving out to Calabasas since 1984, long before the 101 was widened through the pass, and we know the difference between a chimney that needs a quick mortar touch-up and one that’s been quietly deteriorating behind stucco since the Reagan administration.
Calabasas sits in a Very High Fire Hazard Severity Zone. After the Woolsey Fire burned to the city’s edge in 2018, LA County fire code made spark arrestor compliance non-negotiable for every wood-burning chimney here. We find them missing, corroded, or clogged with nesting material on homes throughout The Oaks of Calabasas and along Mulholland Highway, which is why Chimney Cleaning & Sweep - Calabasas service matters here. That’s not a scare tactic. It’s the reason we carry DuraFlex arrestor assemblies and Famco screening on every truck. Call (844) 803-1545. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Calabasas’s Preferred Chimney Repair Company
We’ve worked on chimneys in Calabasas for over 42 years. The estate homes off Park Granada, the Spanish revivals near Calabasas Road, the custom builds tucked into the hills above Las Virgenes Canyon - we’ve repointed mortar, rebuilt crowns, and replaced flue liners in all of them. Russell Haines has personally trained every technician on our team, and each one arrives background-checked, uniformed, and carrying a Level-2 camera rig that lets you see exactly what we see.
Our Calabasas customers don’t leave reviews on apps they don’t use. They tell their neighbors. They call us back when the guest wing fireplace needs attention, or when their adult children buy a place off Mulholland and need someone who won’t treat them like a sales lead. Most repairs in Calabasas are completed in one visit. The number on your estimate is the number on your invoice. Our 90-Day Done Right Promise covers every job in writing, no arguing, no paperwork chase. If it’s not right, we come back. That’s been our way since 1984.
Our Chimney Repair Services in Calabasas
Mortar Repointing
The custom homes built during Calabasas’s 1985-to-2005 boom used mortar mixes that weren’t designed for decades of Santa Ana wind abrasion and thermal cycling. We grind out deteriorated joints to proper depth and repoint with HeatShield-compatible refractory mortar formulated for Southern California’s expansion-contraction patterns. In communities like The Oaks, where chimneys often serve multiple flues for two or three fireplaces, failed mortar joints create hidden pathways for heat and combustion gases. We document the full joint profile with camera inspection before and after. Done right, and we stand behind it.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is rampant on Calabasas chimneys where irrigation systems saturate the base and morning fog wicks upward through porous clay brick. The mid-1980s through late-1990s construction period here coincided with a supply of lower-grade brick that simply wasn’t engineered for freeze-thaw, or in our case, saturate-dry cycling. We remove spalled units, match replacement brick for color and absorption rate, and rebuild with proper weep details so water exits instead of pools. For extensive spalling on chimneys above rooflines visible from Las Virgenes Road, we also assess whether the crown and cap are funneling water into the wall, because brick repair without crown correction is money spent twice.

Chimney Waterproofing
Calabasas averages just 17 inches of rain annually, but it arrives in concentrated winter bursts that exploit every hairline crack. Our waterproofing treatment uses vapor-permeable sealants from professional-grade lines - never the hardware-store films that trap moisture inside and accelerate deterioration. We apply it after all mortar and brick repairs are complete, with particular attention to the chimney-shoulder transition where stucco meets masonry on many Calabasas estate homes. That junction fails silently, and it’s where we find the most hidden damage during Level-2 inspections in 91302 and 91372.

Flashing Repair
Step flashing and counterflashing on Calabasas homes take abuse from Santa Ana gusts that lift shingles and drive rain uphill. The large roof planes and complex valleys on custom homes near Mulholland and throughout the hills create multiple failure points. We fabricate custom flashing from copper and coated steel, seal with high-temperature compounds rated for chimney expansion, and integrate with your existing roofing without voiding warranties. Most flashing repairs in Calabasas run $350 to $850 and finish in under four hours. We also handle Chimney Cap & Crown in Calabasas when the flashing failure has compromised the crown base.

No callbacks, no “we’ll return next week.” We’ll be there when we say.
Common Chimney Repair Problems We See in Calabasas Homes
- Crown cracks from thermal shock. The concrete crowns on 1990s Calabasas homes were poured with minimal reinforcement and no overhang. After thirty years of daily expansion and contraction, they’ve fractured into water-funnels. We rebuild with poured concrete or pre-formed crown forms, sloped properly to shed water away from the flue.
- Missing or non-compliant spark arrestors. LA County fire code requires them. We routinely find them absent on estate homes in The Oaks, or rusted through on properties along Las Virgenes Canyon where salt air from the marine layer accelerates corrosion. This is a code violation and a defensible-space liability in a Very High Fire Hazard Severity Zone.
- Nesting blockages in rarely-used flues. Calabasas homeowners often have two or three fireplaces but use only the family room unit. Guest wing and formal living room flues become prime real estate for birds and squirrels, especially between Santa Ana events when ambient temperatures drop. A single spark from an inaugural autumn fire can ignite accumulated nesting material and creosote.
- Failed chimney liners in mid-1980s construction. The first wave of Calabasas’s major development used clay flue tiles that crack when exposed to the thermal stress of occasional, high-temperature fires. Cracked liners allow heat transfer to surrounding framing, and in a city where wildfire evacuation is a lived memory, that’s not a maintenance item to defer.

FAQs - Chimney Repair in Calabasas
We typically schedule Calabasas repairs within 24 to 48 hours, and same-day service is often available for active leaks or fire-code violations. Our dispatch routes trucks from the San Fernando Valley base up the 101 and through Malibu Canyon daily, so we’re not driving from Orange County or sending you a subcontractor you’ve never met. Call (844) 803-1545 - a live person will check today’s availability.
Yes. We regularly work in The Oaks of Calabasas, the estates along Mulholland Highway, the custom homes near Park Granada, and throughout the 91302 and 91372 zip codes.

The 90-Day Done Right Promise applies to emergency repairs exactly as it does to scheduled work.
Calabasas pricing runs roughly 10 to 15 percent above the San Fernando Valley average due to hillside access complexity, larger chimney footprints on estate homes, and stricter fire-code compliance requirements. However, our $50 off any repair over $250 and permanent 5% senior and veteran discount often offset that differential. A typical repointing job in Woodland Hills or West Hills might run $160 to $400; in Calabasas, the comparable range is $180 to $450. We don’t adjust pricing based on your address. We adjust based on what your chimney actually needs.
Our 90-Day Done Right Promise applies to every repair we complete in Calabasas with no geographic exclusions. If mortar we repointed fails, if a flashing seal we installed leaks, or if any aspect of our work is not right, we return and make it right - in writing, no arguing, no paperwork chase. After 42 years in this region, we plan to be here when your chimney needs attention again. A company that intends to be in business thirty years from now acts accordingly.
