Fast, Reliable Chimney Repair Across Westmont
Chimney repair in Westmont, CA typically costs $180 for minor mortar repointing up to $4,500 for full rebuilding, with most standard repairs completed in a single visit. Our Chimney Repair team at Hearthstone Chimney Co. of Los Angeles has been answering calls from Westmont homeowners for over 42 years, and we know the post-WWII bungalows along 108th Street, the original brick chimneys on the small ranch homes near Vermont Avenue, and the permit maze that LA County Building & Safety puts in your way. Because Westmont sits in the unincorporated stretch of South LA, not every contractor who shows up understands that county jurisdiction changes everything about how a rebuild gets approved. We do.

Why Hearthstone Chimney Co. of Los Angeles Is Westmont’s Preferred Chimney Repair Company
We’ve worked on chimneys in Westmont since the 1980s, back when many of these homes were still occupied by their original owners. That history means something here. We’ve seen which bungalows on which blocks have the original clay flue tiles that were never meant to last this long. We know that a chimney on a 1950s Westmont ranch with a missing cap has probably hosted two generations of starlings.
Our technicians are background-checked, uniformed, and carry professional-grade materials from HeatShield, Gelco, and Olympia Chimney on every truck. Most repairs finish in one trip. We document every inspection with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise - in writing, no arguing - means if it’s not right, we come back. No paperwork shuffle. No runaround.
Calls come to a live person, not a queue. Same for Westmont as anywhere else we serve.
Our Chimney Repair Services in Westmont
Spalling Brick Repair
Westmont’s coastal-humid air and decades of rare fireplace use create a specific problem: moisture gets in, freezes rarely but enough, and brick faces begin to flake and crumble. We’ve replaced spalled brick on bungalows near Century Boulevard where the previous owner tried DIY tuckpointing with standard mortar from the hardware store. That non-refractory mortar trapped water against the brick. Six years later, the wall was worse. We cut out the damaged courses, matched the existing brick color and texture as close as weathered 70-year-old brick allows, and repointed with refractory mortar rated for chimney temperatures. Done right - and we stand behind it.
Chimney Rebuilding
Some Westmont chimneys are past patch and repair. The original masonry has degraded past the point where repointing buys you anything. Here’s where our local knowledge pays off: because Westmont is unincorporated LA County, any structural rebuild or reline must be permitted through LA County Building & Safety - a distinct process from the nearby city of Inglewood - and homeowners are often unaware until an inspector flags an unpermitted repair. We handle that coordination. On a 1950s bungalow on 108th Street, we found a chimney that had been repointed with standard mortar years ago, but the dense clay flue tiles were spalling from within - hidden until we ran a camera. We cut out the damaged section, installed a HeatShield ceramic liner, and rebuilt the crown with a reinforced concrete cap, all while coordinating the permit with LA County in a single trip so the homeowner could burn safely that same evening. That’s the difference between a sweep with a brush and a company that plans to be in town thirty more years.
Flashing Repair
The step flashing where chimney meets roof is a common leak point on Westmont’s older homes, many of which have seen two or three roof overlays without anyone addressing the flashing beneath. We remove the compromised metal, inspect the deck for rot, and install new galvanized or copper flashing integrated properly with the roofing membrane. No caulk-heavy cover-ups. We do it once.
Chimney Waterproofing
Westmont’s mild winters mean chimneys don’t get the freeze-thaw punishment of colder climates, but the marine layer and occasional heavy winter rains still drive moisture into porous brick. Our waterproofing treatment - a vapor-permeable silane/siloxane sealant from professional-grade suppliers - lets the brick breathe while repelling liquid water. One application, properly done, lasts years.
Mortar Repointing & Tuckpointing
We grind out deteriorated mortar joints to proper depth and repoint with color-matched refractory mortar. On Westmont’s vintage bungalows, we take care to match the original joint profile - struck, weathered, or flush - so the repair doesn’t shout “new work” from the curb.

Trusted Brands We Service in Westmont
We stock parts and materials from HeatShield, Gelco, and Olympia Chimney on our service trucks, which means most Westmont repairs don’t wait on a parts run. HeatShield’s cerfractory foam resurfacing system lets us restore deteriorated clay flue liners without a full tear-out - a significant cost savings on a Westmont bungalow where the tiles are sound structurally but the surface has eroded. Gelco caps and Famco dampers handle the replacement side when original components have simply aged out. No builder-grade substitutes. The number on the estimate is the number on the invoice.
Common Chimney Repair Problems We See in Westmont Homes
- Bird nests and debris in uncapped flues. Technicians working Westmont frequently find chimneys with bird nests packed above the damper - a result of open or missing caps on homes where the fireplace hasn’t been used in years and no one thought to check - making cap installation and nest removal a near-standard add-on to almost every cleaning call in the neighborhood.
- Original clay flue tiles with hidden cracks. These aging chimneys routinely show deteriorated mortar crowns, spalled flue tiles, and dampers frozen in place from decades of rare use. The hairline cracks widen over decades of thermal cycling in the LA Basin, creating dangerous gaps that allow carbon monoxide to seep into living spaces.
- DIY tuckpointing damage. We’ve seen multiple Westmont homes where a previous owner used standard Portland mortar to patch chimney joints. That mortar is harder than the original brick. It traps moisture. In the coastal-humid air, the brick spalls faster than if nothing had been done.
- Frozen or rusted dampers. Dampers that haven’t moved in ten years don’t move easily. Sometimes they don’t move at all. We replace with stainless steel or cast-iron dampers that will still operate in another ten years.
Pricing for Chimney Repair in Westmont, CA
A typical mortar repointing job on a Westmont bungalow runs $180-$450 depending on how many courses need attention. Spalling brick repair, where we’re replacing individual bricks and repointing surrounding joints, usually falls between $350 and $900. Flashing repair starts around $275 and can reach $800 if deck rot requires plywood replacement. Chimney waterproofing on a standard single-flue chimney is $150-$300. Full chimney rebuilding - rare, but necessary when the structure has degraded past saving - ranges from $2,800 to $4,500 in the Westmont market, with LA County permit fees additional.

FAQs - Chimney Repair in Westmont
Yes, if the work involves structural rebuilding or relining the flue. Because Westmont is unincorporated LA County, permits route through LA County Building & Safety, not the city of Inglewood or any municipal office. Cosmetic repointing or cap replacement typically does not require permitting. We handle permit coordination as part of our rebuild service - one less thing for you to navigate. Call (844) 418-0954 and we’ll tell you whether your specific job needs a permit, free of charge.
No - not until it’s been inspected. The LA Basin’s mild winters mean most Westmont residents use their fireplaces only a handful of nights per year at most, creating long idle periods that allow starlings and sparrows common to South LA to nest in uncapped flues and debris to accumulate undisturbed between fires. We recommend a Level-2 camera inspection before the first fire of the season. We’ll show you the photos. You’ll know exactly what you’re dealing with.
Cap installation combined with nest and debris removal. Technicians working Westmont frequently find chimneys with bird nests packed above the damper - a result of open or missing caps on homes where the fireplace hasn’t been used in years and no one thought to check - making cap installation and nest removal a near-standard add-on to almost every cleaning call in the neighborhood. After that, spalling brick repair from decades of moisture exposure on original masonry.
Yes, and we do it regularly on Westmont’s 1940s-1960s housing stock. Original clay flue tiles, never relined, develop hairline cracks that widen over decades of thermal cycling in the LA Basin, creating dangerous gaps that allow carbon monoxide to seep into living spaces. If the tiles are structurally sound, we can resurface with HeatShield cerfractory foam. If they’re spalling or shifted, we install a stainless steel or aluminum liner. We’ll show you camera footage and explain which path makes sense for your chimney and budget.
The damper mechanism has likely corroded or the pivot pins have seized in their brackets - common on Westmont chimneys where dampers haven’t been operated in years. Cleaning removes creosote and debris but doesn’t free a rusted hinge. We can often restore operation with proper lubrication and adjustment. If the damper is cracked or warped, we replace it with a new stainless steel or cast-iron unit that seals properly. A stuck damper isn’t just inconvenient. It wastes heat up the flue when closed, and it won’t open fully in an emergency when you need it. Call (844) 418-0954 - estimates are free.
