We’ve worked on chimneys from the ranch homes along Devonshire Street to the hillside properties near Santa Susana Pass Road for over 42 years. Chatsworth’s 1950s-1970s housing stock, built during the San Fernando Valley’s suburban boom, is now hitting a critical age. Those prefabricated zero-clearance fireplaces were rated for 20-30 years of service. Many are 50 years old. The sheet-metal fireboxes rust. Refractory panels crack. Dampers warp and stick. We find these problems on a routine basis in the 91311 ZIP, and we fix them so they stay fixed.
Why Hearthstone Chimney Co. of Los Angeles Is Chatsworth’s Preferred Chimney Liner & Rebuild Company
Gil Mercer built this company in 1984 on the idea that a chimney sweep should explain what is wrong like a craftsman, not sell like a pitchman. That steady approach resonates in Chatsworth, where homeowners have lived in the same house for twenty, thirty, forty years and have no patience for contractors who treat them like a transaction.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your flue is cracked, we show you the crack. If your liner is sound, we say so. In writing, no arguing - that’s the Keystone Standard.
Response time to Chatsworth is same-day or next-day for standard calls, and we carry professional-grade materials from HeatShield, Gelco, and Famco on our trucks. Most liner replacements and partial rebuilds finish in one visit. No-hassle upfront pricing means the estimate number matches the invoice number.
Calls are answered by a live person 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. A real person.
Our Chimney Liner & Rebuild Services in Chatsworth
Stainless Steel Liner Installation
Stainless steel liners are our most common install in Chatsworth, and for specific reason. In the Very High Fire Hazard Severity Zone that covers large sections of the 91311 ZIP, an uncapped or improperly lined flue is not merely an efficiency problem. Santa Ana winds funneling through the Santa Susana Pass can force embers back down the chimney and into living spaces. A properly sized stainless steel liner with a UL-listed spark arrestor is wildfire mitigation, not just an upgrade. We use DuraFlex and Olympia Chimney products rated for the temperature swings these wind events create.
Flexible Liner Replacement
Older masonry chimneys in Chatsworth’s original ranch tracts often have offset flues or narrow clay liners that cracked during the 1994 Northridge earthquake or simply aged out. A flexible liner navigates these irregularities without tearing out the surrounding brick. Typical cost in Chatsworth runs $2,800-$4,200 for a standard flexible liner replacement, including proper top-sealing and connection to the appliance. We inspect with a camera first to confirm the flue path and identify any hidden damage.
Liner Replacement for Zero-Clearance Fireplaces
This is where Chatsworth’s housing stock gets specific. Those 1960s and 1970s prefabricated zero-clearance units - common in the tract homes between Lassen Street and Nordhoff - were never designed to last half a century. The sheet-metal firebox rusts through. The refractory panels deteriorate. Homeowners often discover the problem only when they call for a cleaning and we find the unit is beyond safe operation. Liner replacement in these systems requires matching the manufacturer’s listed components or, when the unit is obsolete, a certified rebuild solution. We document everything with photos and a written verdict so you know exactly what you’re dealing with.
Partial Chimney Rebuild
When the firebox, smoke chamber, or lower flue has deteriorated but the exterior masonry is sound, a partial rebuild makes sense. In Chatsworth, we commonly perform partial rebuilds on hillside homes near the Santa Susana foothills where non-standard chimney heights and steep rooflines created original construction challenges. Smoke chamber parging, firebox refractory replacement, and flue relining combined - typically $4,500-$7,500 in this market. We rebuild to current Los Angeles Municipal Code, including proper clearances and spark arrestor compliance.

Trusted Brands We Service in Chatsworth
We stock professional-grade materials from HeatShield, Gelco, and Famco on our Chatsworth-area trucks, which means most liner jobs don’t wait for parts. HeatShield’s cerfractory smoke chamber sealant handles the thermal cycling that Santa Ana wind events create. Gelco and Famco caps and arrestors meet UL listing requirements for the VHFHSZ. No builder-grade substitutes. The materials we use are the same ones specified by Los Angeles building inspectors - because passing inspection the first time matters, especially when an escrow or insurance review is pending.
Common Chimney Liner & Rebuild Problems We See in Chatsworth Homes
- Rusted zero-clearance fireboxes in 1960s-70s ranches. The sheet-metal boxes in these prefab units corrode from the inside out, often hidden behind refractory panels until we inspect. Catching this early means a liner replacement. Missing it means hidden structural deterioration and a more expensive rebuild later.
- Santa Ana wind backdrafts in hillside homes. The Santa Susana Pass channels winds strong enough to push smoke, and in a chimney fire, flames, back into living spaces. Liners without proper sealing or backdraft dampers fail this test. We see this on non-standard flue heights near the foothills where original construction didn’t account for the pressure differential.
- Missing or corroded spark arrestors flagged by insurers. Los Angeles Municipal Code requires UL-listed spark arrestors on all solid-fuel chimneys. Homeowners in the VHFHSZ zones increasingly find this cited as a binding deficiency during escrow or insurance renewal. We install arrestors as standard on every liner and rebuild job in these parcels.
- Earthquake-cracked clay flue liners. The 1994 Northridge earthquake damaged more chimneys than many homeowners realize. Hairline cracks in clay liners open under thermal stress, allowing creosote to seep into masonry joints. Our camera inspection finds these before they become a house fire.

FAQs - Chimney Liner & Rebuild in Chatsworth
Chatsworth’s location against the Santa Susana Mountains places many homes in a Very High Fire Hazard Severity Zone, where Santa Ana winds can drive embers down uncapped flues and accelerate chimney fires into structure fires. Stainless steel liners withstand higher temperatures than clay or aluminum, and they pair with mandatory UL-listed spark arrestors to meet wildfire-mitigation standards that flat Valley neighbors don’t face. Call (844) 418-0954 to inspect your flue - estimates are free.
The pass channels and amplifies Santa Ana winds, creating pressure differentials strong enough to backdraft smoke and flames into living spaces through poorly sealed or improperly terminated liners. Liners in Chatsworth hillside homes need proper top-sealing, correct sizing for the appliance, and sometimes backdraft dampers to perform safely. We test draft performance after every install. Call (844) 418-0954 for an inspection.
Yes, if your home is in the VHFHSZ or if you burn solid fuel. Los Angeles Municipal Code requires UL-listed spark arrestors on all solid-fuel chimneys, and insurers increasingly flag missing or corroded arrestors as binding deficiencies in 91311 hillside parcels. We install arrestors as standard on every liner and rebuild job in these zones - skipping it means costly rework when escrow or renewal comes. Call (844) 418-0954 to confirm your compliance.
DuraFlex flexible liners handle the offset flues and narrow clay liners common in Chatsworth’s 1950s-1970s ranch and split-level homes, including earthquake-shifted flues from the 1994 Northridge event. We camera-inspect first to map the flue path, then select the diameter and alloy rated for your appliance. Most flexible liner replacements in Chatsworth run $2,800-$4,200 installed. Call (844) 418-0954 for a camera inspection and exact quote.
We can, but only after determining whether the original unit is still listed and whether the firebox and refractory panels are intact. Many 1960s zero-clearance units in Chatsworth have rusted sheet-metal fireboxes or deteriorated panels that make simple relining insufficient. We document the condition with photos and give you a plain-English verdict: relining, partial rebuild, or full replacement. On a 1960s ranch-style home near the Santa Susana foothills, we discovered the original prefabricated zero-clearance fireplace had a warped damper and deteriorating refractory panels, sending heat into the framing. We installed a custom DuraFlex stainless steel liner, added a UL-listed spark arrestor, and partially rebuilt the smoke chamber to meet current fire codes - ensuring the homeowner passed inspection and avoided insurer red flags. Call (844) 418-0954 to schedule your inspection.
