Fast, Reliable Chimney Liner & Rebuild Across Calabasas
Chimney liner installation and rebuild in Calabasas typically runs $2,800-$7,500 depending on whether you need a stainless steel liner retrofit for a factory-built fireplace or a full masonry rebuild. Most Calabasas jobs are completed in a single day, and our crew carries the parts to do it.
We’ve been driving out to Calabasas since 1984, back when Mulholland Highway was the main route and The Oaks was still new construction. We know the difference between a zero-clearance metal firebox in a 1990s tract home off Park Granada and a custom masonry chimney in the hills above Las Virgenes Road. That matters because the repair isn’t the same, and the parts aren’t interchangeable. If you’re in 91302 or 91372 and your fireplace is smoking, drafting poorly, or hasn’t been inspected since before the Woolsey Fire, call us at (844) 418-0954. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. of Los Angeles Is Calabasas’s Preferred Chimney Liner & Rebuild Company
Calabasas homeowners don’t call us once. They call us when they buy the house, again when they smell smoke in the living room, and ten years later when it’s time to sell and the inspector flags the flue. That repeat business is how we’ve stayed in operation for over 42 years. We don’t chase volume. We do the job so you don’t have to think about it again.
Our technicians are background-checked, uniformed, and trained on the specific prefab fireplace systems installed in Calabasas’s 1980s-2000s housing stock. We document every inspection with photos and a plain-English verdict. No jargon, no scare tactics. If the liner is cracked, we show you the crack. If the cap doesn’t meet VHFHSZ spark-arrester requirements, we explain exactly what that means for your homeowner’s insurance.
We answer the phone with a live person, every hour of every day. Not a callback queue. Not an app. When you call (844) 418-0954, someone picks up who can dispatch a crew to Calabasas, usually same-day or next-day depending on your schedule.
Every job is backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing.
Our Chimney Liner & Rebuild Services in Calabasas
Stainless Steel Liner Installation
Calabasas’s location in a Very High Fire Hazard Severity Zone means your liner isn’t just a vent. It’s a fire barrier. We install heavy-gauge stainless steel liners from DuraFlex and Olympia Chimney rated for the thermal stress caused by Santa Ana wind backdrafts. These aren’t the thin-wall products sold online. The gauge matters because reversed draft superheats the flue metal, and a liner that warps or separates at the seam becomes a direct ignition path to surrounding framing.
Most stainless steel liner jobs in Calabasas run $2,800-$4,500 for a standard factory-built fireplace retrofit. Custom masonry flues in hillside homes above Mulholland can run higher depending on height and access.
Flexible Liner Systems
Not every Calabasas chimney is straight. Homes in The Highlands and Mountain View Estates often have offset flues or tight clearances where a rigid liner won’t pass. We use DuraFlex flexible liners engineered for these conditions, installed with the proper insulation pack to maintain flue temperature and prevent creosote condensation. The Las Virgenes Valley’s colder winter nights mean your flue stays cooler longer, which increases creosote buildup if the liner isn’t properly insulated. We size the flex liner to the appliance, not the other way around.
Flexible liner installations in Calabasas typically fall between $3,200-$5,000.
Liner Replacement for Zero-Clearance Fireplaces
This is where Calabasas’s housing stock gets specific. The 1980s-2000s tract and semi-custom homes in gated communities here were built with factory-built zero-clearance fireplaces, not true masonry. These systems have manufacturer-specific flue liners, firebox panels, and port dimensions. You can’t drop a generic liner into a Heatilator or Superior firebox and expect it to draft correctly.
We inspect for cracked refractory panels, warped metal firebox components, and deteriorated factory liners. When replacement is needed, we source the correct parts from Copperfield and Famco, matched to your unit’s model number. A misfit liner causes smoke spillage, carbon monoxide risk, and failed home inspections.
Zero-clearance liner replacements in Calabasas generally cost $2,800-$4,200.
Partial and Full Chimney Rebuild
Sometimes the liner isn’t the problem. The chimney structure itself has failed. Spalling brick, deteriorated mortar, or a shifted chimney crown can make liner installation impossible without rebuilding first. We handle partial rebuilds of the firebox and smoke chamber, as well as full chimney rebuilds from the roofline up.
In Calabasas’s hillside neighborhoods, chimney exposure to upslope canyon winds accelerates mortar deterioration. We’ve rebuilt chimneys in The Oaks where the original construction used standard mortar instead of the high-sulfate-resistant mix required for Santa Ana wind exposure. We don’t repeat that mistake.
Partial rebuilds start around $4,500-$6,500. Full rebuilds in Calabasas typically run $7,500-$15,000 depending on height, scaffolding requirements, and materials matching.

Trusted Brands We Service in Calabasas
We stock professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Calabasas customers, this means we don’t order parts and make you wait two weeks. Our trucks carry the common liner diameters and cap configurations for the prefab systems installed in local tract homes, and our warehouse keeps DuraFlex stainless and flexible inventory on hand. When a Santa Ana event is forecast and your cap is missing or damaged, that turnaround matters.
Common Chimney Liner & Rebuild Problems We See in Calabasas Homes
- Unlined or deteriorating zero-clearance fireboxes. The original flue panels in 1980s Calabasas tract homes have often warped or cracked from decades of thermal cycling. Homeowners smell smoke or notice staining on the wall surround. We replace the factory liner with a correctly sized stainless steel system.
- Incorrect cap selection. Basic rain caps don’t stop Santa Ana backdrafts. We routinely find smoke shelves packed with canyon oak leaves and ash in homes near Malibu Creek State Park. The debris blocks the flue and creates a fire hazard. A wind-directional spark-arresting cap solves this.
- Partial rebuilds with mismatched port sizes. Some contractors install generic liners on prefab fireplaces without verifying the manufacturer spec. The result is poor draft, smoke spillage into the living room, and a failed inspection when you sell. We match port dimensions exactly.
- Thermal shock damage from wind-driven backdraft. Santa Ana winds reverse chimney flow, pulling hot combustion gases back down the flue. This superheats liner seams and crown mortar in ways flatland chimneys never experience. Calabasas liners need heavier gauge material and proper insulation to survive it.

FAQs - Chimney Liner & Rebuild in Calabasas
Calabasas sits in a state-designated Very High Fire Hazard Severity Zone where Santa Ana winds reverse chimney draft, blowing debris into flues and superheating liner seams. Heavy-gauge stainless steel with proper insulation and a wind-directional spark-arresting cap is required to withstand this backdraft-driven thermal stress, a condition rare in neighboring flatland cities like Woodland Hills or West Hills. We install DuraFlex and Olympia Chimney liners rated for these conditions. Call (844) 418-0954 to discuss your exposure.
Yes. Most 1990s Calabasas homes in The Oaks, The Highlands, and Mountain View Estates were built with factory-built zero-clearance fireplaces from manufacturers like Heatilator or Superior. These require model-specific liners and firebox panels, not generic inserts. We source the correct parts from Copperfield and Famco, matched to your unit’s dimensions. A misfit liner causes smoke spillage and failed inspections. We’ll verify your model number during our Level-2 camera inspection. Call (844) 418-0954 to schedule.
Santa Ana winds reverse normal chimney draft, pulling combustion gases back down the flue and depositing canyon debris on the smoke shelf. This superheats liner metal and mortar joints in ways standard construction doesn’t anticipate. We’ve found oak leaves and ash packed into flues that homeowners thought were clean. The solution is a wind-directional spark-arresting cap and a properly insulated heavy-gauge liner. Call (844) 418-0954 and we’ll check your cap configuration.
Most liner replacements and rebuilds in Calabasas require a permit from LA County because of the VHFHSZ fire code enforcement. We handle the permit application as part of our standard process and schedule the required inspection. The permit cost is typically included in your upfront estimate. We don’t start work until the permit is approved, and we don’t leave until it passes inspection. Call (844) 418-0954 and we’ll walk you through the specific requirements for your property.
A cracked factory-built metal flue in a Calabasas zero-clearance fireplace usually requires full liner replacement, not repair. The crack indicates thermal fatigue or corrosion at the seam, and patch jobs fail within a season because the metal continues to expand and contract. We install a new stainless steel liner sized to your firebox with proper insulation. In rare cases, a minor crack in a masonry flue tile can be addressed with a HeatShield cerfractory seal, but we make that call only after camera inspection. Call (844) 418-0954 for a free inspection and honest verdict.
