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 means dealing with what decades of light use and dry Southern California air do to an old masonry fireplace: cracked terra-cotta tiles, rusted dampers, and crowns that have turned to grit. Most Westmont chimneys were built between the 1920s and 1950s, and many still carry their original flue liners. That means our repair calls here lean toward structural fixes, cap installations, and liner work rather than creosote-heavy sweeping jobs. If your fireplace has been acting up or you spotted water stains near the chimney, call Ontario Chimney at (833) 467-7685 for a straight answer and a free estimate.
Why Westmont Homes Are Different
Westmont sits in the South LA basin inside ZIP 90047, and the housing stock tells the story: early- to mid-20th-century single-story bungalows and Spanish Colonial Revival stucco homes, most with original brick or masonry fireplaces. These fireplaces were built for occasional use, not high-efficiency heating, and their terra-cotta flue liners were rarely upgraded when kitchens and bathrooms got remodeled. The result is a neighborhood full of fireboxes and dampers that are original to the house, often unlined above the smoke chamber, and frequently missing a proper chimney cap.
The climate changes the work, too. Westmont’s mild, dry Mediterranean weather means fireplaces get lit only a handful of times each winter, so creosote buildup stays light. What does accumulate is deferred maintenance: dry heat and Santa Ana winds bake old mortar until it crumbles, and the region’s wildfire seasons make a spark arrestor a practical necessity on any uncapped flue. In the older bungalows off Western and Manchester, we routinely find fireplaces that were bricked off during remodels decades ago, with the flue never properly sealed. A routine sweep sometimes turns into discovering birds, rain, and a dead chimney behind a wall.
Styles & brands we work with
Our Main Westmont Services
Most Westmont homeowners call us for one of two reasons: a chimney that has not been swept in years, or a dryer vent that has never been cleaned since the house was built. Both are maintenance issues that quietly get worse.
Chimney Sweep in Westmont
A sweep in Westmont is less about heavy creosote and more about clearing out what time left behind: soot-loaded dampers, broken terra-cotta chips in the smoke shelf, and the occasional bird nest below an uncapped flue. We scope the flue before and after so you see exactly what came out. The older bungalows here often hide a second issue: a flue that was never capped when the fireplace was bricked off, letting rain and debris sit in the chimney for years. Our Chimney Sweep in Westmont page covers what a typical call involves and what we find in this housing stock.
Dryer Vent Cleaning in Westmont
Dryer vents in Westmont run through tight utility closets and under slab foundations in many of the older homes, which means lint gets trapped at elbows and long horizontal runs. That lint is fuel. The NFPA identifies dryers as a leading cause of house fires, and the fix is routine: clean the full run from dryer to exterior termination, check airflow, and tell you if the venting material itself is a problem. We treat this as a standalone fire-safety service, not an add-on. See Dryer Vent Cleaning in Westmont for the full scope and what to expect.

Chimney Repair in Westmont
Chimney repair in Westmont is usually about age, not accidents. The homes here run from the 1920s through the 1950s, and a chimney that has seen 70 or 80 years of Santa Ana winds and dry heat will start failing at the top first: crown cracks, missing caps, spalled brick, and terra-cotta flue tiles split open inside. Because Angelenos light fires only a few times each winter, problems hide for years, and by the time a homeowner notices a water stain or a musty smell, the damage is already structural. We repair it from the top down, and we show you camera evidence before recommending any work. Ontario Chimney has served Westmont since 2014, and we handle the full Chimney Repair scope, from crown to firebox.
Chimney Crown Repair
Signs you need it
Cracks in the concrete crown let rainwater into the chimney chase, which shows up as efflorescence on the exterior brick, damp smells near the fireplace, or chunks of crown material on the roof or ground.
What it costs in Westmont
Chimney crown repair in Westmont typically runs $145 to $610 depending on how much of the crown is salvageable versus needing a full recast.
How we do it
We clean and prep the existing crown surface, fill hairline cracks with a flexible crown sealant, or strip and recast badly deteriorated crowns with a proper overhanging form so water drips away from the flue, not into it.
Chimney Cap Installation
Signs you need it
If you can see daylight through an open flue from your yard, hear birds in the chimney, or smell rain-wet soot after a storm, your Westmont chimney is uncapped and pulling water, debris, and animals down the flue.
What it costs in Westmont
Chimney cap installation in Westmont generally falls between $85 and $1,200, with the final number set by flue size, cap material, and whether you need a standard cap or a custom multi-flue unit with a spark arrestor.
How we do it
We measure the flue opening, match a stainless or galvanized cap from Famco or Copperfield to the dimensions, and mechanically fasten it to the flue tile or crown so it stays put in Santa Ana winds.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the chimney, peeling paint on the chimney chase, or damp drywall in the attic after rain all point to failed flashing where the chimney meets the roofline.
What it costs in Westmont
Chimney flashing repair in Westmont runs $150 to $1,000, depending on whether we can reseal the existing metal or need to cut in new step and counter flashing.
How we do it
We pull the shingles around the chimney, inspect the existing flashings for rust and gaps, replace or reseal as needed, and re-bed the counter flashing in sealant so water runs past the chimney instead of behind it.
What Chimney Repair Costs in Westmont
| Item | Typical range in Westmont |
|---|---|
| Chimney crown repair | $145 – $610 |
| Chimney cap installation | $85 – $1,200 |
| Chimney flashing repair | $150 – $1,000 |
What pushes a Westmont repair bill higher is decades of deferred maintenance: a crown that crumbled because a cap was never installed, or flashing that rusted through after 40 years of morning fog. Every repair starts with a camera inspection, and you get the photos before you commit to anything.
How much does a chimney cap cost in Westmont?
A chimney cap in Westmont runs $85 to $1,200. The lower end is a standard single-flue galvanized cap; the higher end covers custom stainless caps for oversized or multi-flue chimneys with a spark arrestor for wildfire season. Call (833) 467-7685 for an exact quote, and we will match the cap to your flue dimensions.
Do I need a new liner or can the old one be resurfaced?
Not every cracked liner needs full replacement. If the terra-cotta tiles have minor cracking but the structure is sound, HeatShield ceramic resurfacing can restore the flue to a code-compliant surface at a lower cost than a tear-out. We scope the flue and show you the condition before recommending either path.
Brands We Service in Westmont
We stock and install parts from Famco, Copperfield, DuraFlex, and HeatShield, the same brands certified chimney professionals specify, not big-box substitutes. Most common caps, dampers, and liner components are on our trucks or available within days, which keeps most Westmont repairs to a single visit. See our brands for the full list of what we work with.
