Westmont sits just west of the 110 Freeway, a pocket of modest single-family homes where original brick masonry chimneys from the 1940s through 1960s still stand on roofs from Century Boulevard down to 108th Street. Our technicians carry DuraFlex stainless steel liners and HeatShield resurfacing materials on every truck, so we’re not driving back to a warehouse while your chimney sits open. That’s the point of a one-trip operation. We’ve been serving this corridor for over 42 years, and we plan to be here when your grandchildren need their chimneys checked.

Our response time to Westmont averages under 90 minutes during business hours, and a live person answers the phone 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When a chimney liner fails on a cold December evening in Westmont, someone real picks up.
We recently serviced a 1950s ranch home on Gramercy Place where the original clay flue liner had spalled after years of disuse, creating a fire hazard. Our crew installed a new DuraFlex stainless steel liner and rebuilt the deteriorated crown, completing the job in one trip despite the long service drive and oversized workshop garage doors that required extra time. The homeowner had lived there 34 years and never used the fireplace. Now she does, safely.
Our Chimney Liner & Rebuild team understands Westmont’s specific conditions: the mild LA Basin climate that keeps chimneys dormant, the LA County permit process that city contractors stumble over, and the original clay flue tiles that fail precisely when homeowners finally decide to light a fire after decades of neglect.
Our Chimney Liner & Rebuild Services in Westmont
Stainless Steel Liner Installation
A stainless steel liner is the permanent fix for Westmont’s aging clay flue tiles. We install DuraFlex and Olympia Chimney liners that carry a lifetime warranty and handle both wood-burning and gas appliances. In Westmont’s 90047 ZIP code, we typically see these jobs run $2,800-$4,200 for a standard single-flue installation, including removal of the damaged clay liner and proper sizing for your appliance. The mild winters here mean most homeowners only burn a few nights yearly, but that infrequent use is exactly what causes thermal shock damage to old clay tiles when they finally heat up after years of sitting cold.
Flexible Liner Solutions
Some Westmont chimneys have offset flues or tight cleanout areas that rigid stainless can’t navigate. Flexible liners from DuraFlex solve this without tearing down walls. We snake these through existing masonry, then top the chimney with a proper cap to keep out the starlings and sparrows that plague South LA neighborhoods. Flexible liner installations in Westmont generally fall between $3,200-$4,800 depending on flue length and accessibility.
Liner Replacement
When a clay flue liner has spalled, cracked, or shifted, partial replacement won’t do. We extract the damaged sections and install a complete new system, inspecting the surrounding masonry with our camera as we go. Westmont’s original bungalows often have liners that were never designed for modern heating appliances - too narrow, too short, or improperly pitched. Our replacement jobs include a written sizing report and the 90-Day Done Right Promise: in writing, no arguing.
Partial and Full Chimney Rebuild
Sometimes the liner isn’t the only problem. Decades of moisture intrusion through uncapped flues rot mortar joints and spall brick faces from the inside out. A partial rebuild addresses the firebox, smoke chamber, or crown; a full rebuild starts from the roofline up. In Westmont, full rebuilds typically range $5,500-$7,500, partial rebuilds $1,800-$3,400. We handle LA County permits directly, so you’re not standing in line at the Norwalk office wondering if your paperwork is right.

Trusted Brands We Service in Westmont
We don’t substitute builder-grade materials to pad margins. Our trucks stock DuraFlex stainless liners, HeatShield resurfacing mortar, and Famco chimney caps because these are the brands that professional sweeps have relied on for decades. For Westmont homeowners, this means faster turnaround - no waiting on warehouse shipments while rain season approaches. We size and fit on site, and we document every installation with photos for your records. Done right, and we stand behind it.
Common Chimney Liner & Rebuild Problems We See in Westmont Homes
- Original clay flue tiles spall from decades of rare use. Westmont’s mild climate means most fireplaces sit cold year-round. When a homeowner finally lights a fire, the rapid thermal expansion cracks tiles that have absorbed moisture through hairline fractures. We find this on nearly every 1940s-1960s bungalow we inspect.
- Bird nests packed above rusted dampers block proper liner installation. Uncapped chimneys in Westmont attract starlings and sparrows common to South LA. Nests compact above dampers that haven’t opened in years, creating fire hazards and preventing proper draft even after cleaning.
- Uncapped chimneys allow debris and moisture to accumulate. Rainwater and organic matter enter open flues, corroding metal components and deteriorating mortar crowns. By the time a Westmont homeowner notices a leak stain on the ceiling, the liner and surrounding masonry often need simultaneous repair.
- LA County permit routing confuses homeowners and out-of-area contractors. Because Westmont is unincorporated, chimney work requires LA County Building & Safety approval, not city permits. Contractors unfamiliar with this jurisdiction often file incorrectly, causing delays and failed inspections.

FAQs - Chimney Liner & Rebuild in Westmont
Clay flue tiles absorb moisture through microscopic cracks during long idle periods, then spall and crack when rapid heating finally occurs. Westmont’s mild LA Basin climate encourages this pattern - chimneys sit cold 360 days a year, then face thermal shock on the rare nights residents burn. We inspect with a camera to confirm spalling before recommending replacement. Call (844) 418-0954 for an exact quote - estimates are free.
Yes. Because Westmont is unincorporated LA County, all chimney liner and rebuild permits route through LA County Building & Safety, not a city office. Out-of-area contractors frequently file incorrectly, causing inspection failures and costly rework. We handle LA County permitting directly as part of our standard process. Call (844) 418-0954 for an exact quote - estimates are free.
Most chimney damage hides inside the flue or behind the firebox where homeowners can’t see it. Our Level-2 camera inspection reveals spalled tiles, deteriorated mortar, and moisture damage invisible from the street. In Westmont’s 90047 area, we find serious internal damage in roughly 60% of chimneys over 50 years old that appeared structurally sound from the roofline. Call (844) 418-0954 for an exact quote - estimates are free.
We bring appropriately sized equipment and schedule adequate time for properties with extended access drives or detached workshops. Our Gramercy Place job required maneuvering around an oversized workshop garage door - we completed the liner installation and crown rebuild in one planned trip rather than two rushed ones. We’ll be there when we say, with what we need. Call (844) 418-0954 for an exact quote - estimates are free.
Very common. Starlings and sparrows throughout South LA nest in uncapped flues, especially on homes where fireplaces haven’t been used in years. We remove nests and install proper caps as a near-standard add-on to Westmont cleaning calls. A capped flue prevents recurrence and protects your new liner investment. Call (844) 418-0954 for an exact quote - estimates are free.
