Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Westmont, CA
Chimney repair in Westmont usually comes down to one thing: older clay-tile flues and exterior masonry stacks that have spent decades absorbing South LA’s dry heat, then cracking open when the first winter storm rolls through. Mantel Chimney Sweep has served Westmont since 2018, and the calls we get most often aren’t about a chimney that’s stopped drawing, they’re about water stains on a living room wall after a rare heavy rain, or a neighbor down the block asking why smoke is drifting sideways from the house next door. If you need a sweep, a repair, or a liner replacement on a 1920s – 1950s Westmont bungalow, call us at (844) 821-5749 for a straight answer.
Why Westmont Homes Are Different
Westmont sits as a small unincorporated pocket of South LA, built tight alongside the 110 freeway corridor, and the housing stock tells the story of when it went up: single-story stucco bungalows and modest post-war tract houses from the 1920s through the 1950s, most with original brick fireplaces and exterior masonry chimneys rather than the factory-built inserts you see in newer developments. That matters because clay-tile flue liners and hand-poured mortar crowns from that era simply aren’t meant to last eighty or ninety years, especially in a climate that sees so little rain that the mortar dries out, shrinks, and begins to spall. Then a real storm arrives, the water finds every crack, and the damage accelerates fast.
The freeway-adjacent location shapes the work in another way too. Homes sit close together on tight lots, so a chimney that smokes badly or vents creosote odors doesn’t just affect the homeowner, it travels to the family next door within minutes. Westmont isn’t a snow country market where heavy creosote buildup is the constant issue. Here the risk is water intrusion and masonry decay from a dry, near-desert climate punctuated by concentrated winter rains. Our technicians know to look for cracked crowns, spalling brick faces, and deteriorated clay tile flues that have silently failed over years of thermal cycling.

Our Main Westmont Services
Most Westmont homeowners call us for one of two reasons: a fireplace or chimney that needs a proper cleaning, or a dryer vent that hasn’t been cleared in years and is quietly becoming a fire hazard. Both services are covered in detail on their own pages.
Chimney Sweep in Westmont
A chimney sweep in Westmont matters because smoke and creosote don’t behave the same way in a dry climate as they do in a wet one. The creosote that builds up in a flue here is often drier and more brittle, which can make it flake and accumulate in bends where a visual inspection from the firebox misses it. We clean the full flue, check the smoke shelf, and report on the liner condition while we’re in there, because a sweep that ignores liner cracks is only doing half the job. For homeowners in 90047 whose fireplaces haven’t been serviced in years, this is where it starts. Learn more on our dedicated Chimney Sweep in Westmont page.
Dryer Vent Cleaning in Westmont
Dryer vent cleaning gets overlooked until a load of laundry takes two cycles to dry, or until a homeowner reads about how many residential fires start inside clogged dryer exhaust lines. In Westmont’s older homes, dryer vents often run long horizontal distances through attics or down narrow exterior walls, which makes lint accumulation worse than in newer, shorter-vent construction. We clear the entire run, not just the first few feet behind the dryer, and we check the termination point outside to confirm airflow is actually moving. See the full scope of work on our Dryer Vent Cleaning in Westmont page.

Chimney Repair in Westmont
Chimney repair in Westmont is rarely optional once the damage shows itself. Homes built in the 1920s through the 1950s with original clay tile liners have flues that crack over time, not from any single event but from decades of dry heat, thermal expansion, and the slow breakdown of mortar joints. When winter rain hits those cracks, water runs down the inside of the chimney and into the masonry, staining ceilings, softening drywall, and widening the original rupture every time the cycle repeats. We repair what others can only report, which means we don’t just hand you a diagnosis and leave. We fix the flue, the crown, the flashing, or the cap, and we use professional-grade materials from names like Chimney Repair suppliers Olympia Chimney and Famco so the patch holds in South LA’s dry-and-storm climate. A clean sweep is the baseline, repair expertise is the difference, and in Westmont the difference shows up as a chimney that stays dry through the next real rainy season.
Chimney Cap Installation
Signs you need it
Rain water or bird nesting material inside the flue, visible rust staining on the cap or crown, or a cap that’s missing entirely after a Santa Ana wind event.
What it costs in Westmont
Chimney cap installation in Westmont typically runs $150 to $350 depending on the flue size and whether a custom bracket is needed for an older masonry chimney.
How we do it
We measure the flue opening, fit a stainless or galvanized cap sized for the tile, secure it with mechanical fasteners rather than adhesive, and check that the spark arrestor mesh meets code for your fireplace type.
Chimney Cap Replacement
Signs you need it
A cap that’s rusted through, blown off by wind, or so dented that the mesh no longer keeps embers and animals out.
What it costs in Westmont
Replacing a failed chimney cap in Westmont falls between $150 and $350, and the job goes faster when the old cap’s mounting hardware is still intact.
How we do it
We remove the damaged cap, inspect the crown and flue tile beneath it for related damage, prep the mounting surface, and install a new cap sized to the original flue so the fit is tight and the spark screen does its job.
Chimney Liner Installation
Signs you need it
Crumbling clay tile pieces falling into the firebox, visible cracks in the flue during a camera inspection, or water penetration that persists even after the crown and flashing have been repaired.
What it costs in Westmont
Chimney liner installation in Westmont typically runs $2,800 to $4,800 for a standard single-story home, with the range driven by flue height, existing tile condition, and whether we’re installing a DuraFlex stainless liner.
How we do it
We document the existing flue with a camera, remove collapsed tile where necessary, and pull a DuraFlex flexible stainless steel liner through the flue, connecting it at the appliance and terminating it with a proper cap assembly.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling around the chimney chase, damp drywall near the roofline, or visible gaps where the flashing meets the masonry and the roof.
What it costs in Westmont
Chimney flashing repair in Westmont typically falls between $200 and $750 depending on whether we’re re-sealing a single side or replacing step flashing where the roof meets the stack.
How we do it
We remove the old flashing or failing sealant, inspect the roof-to-chimney junction for rot or hidden gap openings, and install new flashing with proper overlap and a high-quality sealant rated for South LA’s thermal swings.
Chimney Crown Repair
Signs you need it
A crown with visible cracks, a spalled or crumbling surface, standing water that pools on top of the chimney, or water coming down the inside of the flue during rain.
What it costs in Westmont
Chimney crown repair in Westmont typically costs $350 to $950 depending on whether we’re filling cracks with a polymer patch or rebuilding the full crown with new mix and proper overhang.
How we do it
We chip away the deteriorated concrete, build a form to create proper slope away from the flue, pour a new crown mix, and leave it curing with the right overhang so water sheds away from the flue tile rather than running down it.

How often should a Westmont chimney be inspected after a repair?
After any structural repair in Westmont, we recommend a camera inspection at the one-year mark to confirm the fix is holding through a full cycle of dry heat and winter rain. From there, an annual visual check is enough for most homes, with a full sweep every one to two years depending on use.
Can a cracked flue liner be repaired without replacing it?
Sometimes, yes. If the damage is limited to small cracks and spalling rather than collapsed tile, a cerfractory sealant like HeatShield can restore the flue’s integrity without a full liner installation. We’ll show you the camera footage so you can see exactly what we’re recommending and why. Call (844) 821-5749 to schedule an inspection.
Brands We Service in Westmont
We work with a curated set of professional chimney-industry brands, not whatever is cheapest at the supply counter. In Westmont that means Olympia Chimney caps and chase covers, Famco termination caps, and Copperfield flashing materials, plus our brands partners like DuraFlex when a full liner installation is the right fix. Most standard parts are on our trucks, and special-order items usually arrive within a few business days.

What pushes a Westmont quote toward the upper end of these ranges is usually the age of the house. A 1940s bungalow with original clay tile and a chimney that has been re-roofed around but never re-lined takes longer to work on than a well-maintained flue, and if we’re repairing masonry around tight freeway-adjacent lot lines, access can add time. Every quote is flat-price and agreed before we start work, based on what we find during the inspection, not after.
Neighborhoods We Serve in Westmont
Westmont itself is compact, but the blocks vary enough that we know what to expect when the address comes in. We’re in and out of the bungalow-heavy streets around the 110 corridor regularly, and we’re familiar with the post-war tract pockets where exterior masonry chimneys sit on narrow side yards with limited ladder access.
- The 90047 single-story bungalow core
- Streets bordering the 110 freeway corridor
- Post-war tract blocks off Vermont Avenue
- Homes along the unincorporated edges near West Athens
We schedule Westmont jobs throughout the week, and we batch our visits so a repair that needs a follow-up inspection or a second material run doesn’t leave you waiting more than a day or two between steps.

FAQs About Chimney Company in Westmont
Most Westmont calls get an in-person visit within a few business days, and emergency water-intrusion issues during a storm cycle get prioritized. If water is actively coming down your flue, call (844) 821-5749 and we’ll get someone out to assess it as soon as possible.
Most chimney repairs, sweeps, and liner installations don’t require a separate permit from the county, but major structural rebuilds can. We can’t speak for every situation, so we’ll tell you during the inspection if your specific repair falls into a category that requires county sign-off. Either way, we do the work to code.
Then we’ll sweep it and tell you honestly that’s all you need. A clean sweep is the baseline, and if the flue is in good shape, we’ll say so without inventing a repair. That’s the whole point of a camera inspection, you see what we see, and you decide. Call (844) 821-5749 for a free estimate.

What Westmont Customers Say
"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
— Michelle Brooks"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
— Eric Mercer"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Rachel Lawson
