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
Most chimney repair calls we take in Westmont trace back to the same root cause: decades-old masonry fireplaces in mid-century tract homes that have spent more years idle than in use. The dry South Bay climate lets creosote harden into a glaze, while uncapped flues invite birds and squirrels to build nests above the damper. We repair what we find in those flues, from cracked crown to rotted flashing, using the right material for each specific failure. If you suspect a problem, call (855) 341-3461 and we’ll tell you exactly what we’re seeing.
Why Westmont Homes Are Different
Westmont’s housing stock is largely post-war suburban tract construction, single-story homes and small multi-family buildings near South LA. Most fireplaces in the 90047 ZIP are masonry, built with the original clay flue tile and damper assemblies installed sixty or seventy years ago. Those systems have aged. Flue tiles crack, mortar joints erode, and damper assemblies seize. The fireplaces themselves rarely see the heavy seasonal use common in colder climates, which means soot and creosote sit undisturbed for months or years, hardening into deposits that a standard brushing can’t remove.
The mild, dry climate creates a second problem. Fireplaces go dark for most of the year, and uncapped flues become dry, quiet spaces that attract birds, squirrels, and debris. When a Westmont homeowner finally lights a fire in November or December, that dormant flue may be packed with nesting material above the damper. A chimney repair call here often starts with clearing a nest, then finding the water damage or cracked tile underneath. Walnut Chimney has served Westmont since 2017, and the pattern holds: deferred maintenance plus pest intrusion, not heavy heating loads, drives the work.
Styles & brands we work with
Our Main Westmont Services
Westmont homeowners call us most often for two things: a chimney that hasn’t been swept in years and a dryer vent that’s quietly packed with lint. Both are fire hazards, and we handle them together when it makes sense.
Chimney Sweep in Westmont
A chimney sweep in Westmont usually means clearing years of hardened soot rather than a season’s worth of creosote. In these long-idle flues, we often find glazed deposits that need more than a wire brush, along with nests, leaves, and the occasional squirrel cache above the damper. We inspect as we clean, because the real value in a Westmont sweep is catching the cracked tile or failed damper before it becomes a repair. See Chimney Sweep in Westmont for the full process and what we look for.
Dryer Vent Cleaning in Westmont
Dryer vents in Westmont’s older homes tend to be short runs through an exterior wall, but they still accumulate lint against the screen and at every bend. The NFPA cites dryers as a leading cause of home fires, and a vent that hasn’t been opened in years is a measurable risk. We treat this as a core safety service, not an add-on, and we’ll flag any venting that doesn’t meet current code. See Dryer Vent Cleaning in Westmont for what a cleaning includes.

Chimney Repair in Westmont
Chimney repair in Westmont is usually about age, not accidents. The original clay flue liners installed in post-war tract homes have been absorbing heat and moisture for decades, and hairline cracks become a serious hazard when hot gases can reach the framing. This page is the city’s resource for chimney repair work, from caps to crowns to full relining. Westmont’s mild, dry weather means a small flashing leak can go unnoticed for a long time, quietly staining the ceiling around the fireplace and rotting the framing behind the masonry. We fix all of this under one roof. See our Chimney Repair hub for the full scope of work.
Chimney Cap Installation
Signs you need it
Birds nesting in the flue, water staining on the firebox floor after rain, or damp-smelling air from the fireplace are the common Westmont indicators.
What it costs in Westmont
Chimney cap installation in Westmont typically falls between $240 and $440, depending on flue size and access.
How we do it
We measure the flue opening, select a cap from Gelco or Copperfield that fits without restricting draft, and secure it to the crown with proper anchors.
Chimney Cap Replacement
Signs you need it
A rusted, split, or missing cap that no longer stops rain and animals is the trigger for replacement.
What it costs in Westmont
Replacing a chimney cap in Westmont typically runs $260 to $480, including removal of the old unit and fitting the new one.
How we do it
We remove the old cap, inspect the flue opening and crown for damage, then install a correctly sized replacement from Famco or Copperfield.
Chimney Liner Installation
Signs you need it
Flue tile cracks found during inspection, visible mortar erosion between tile sections, or a furnace flue that’s spilling exhaust into the home.
What it costs in Westmont
A new chimney liner in Westmont generally ranges from $2,100 to $4,500, depending on flue length and whether insulation is included.
How we do it
We assess the flue, then install a code-compliant DuraFlex flexible liner sized for the appliance served, anchoring it at the top and connecting it at the bottom.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the fireplace or drip marks on the firebox wall after heavy rain point to failed flashing.
What it costs in Westmont
Chimney flashing repair in Westmont typically costs between $420 and $790, depending on how much of the old flashing can be salvaged.
How we do it
We cut back the old flashing, inspect the roof-to-chimney junction, then install new step flashing and counterflashing with proper sealant.
Chimney Crown Repair
Signs you need it
Cracks across the crown surface, chunks of mortar missing, or water pooling on top of the chimney after rain all mean the crown is failing.
What it costs in Westmont
Crown repair or rebuild in Westmont runs about $550 to $950, depending on crown size and whether a full recast is needed.
How we do it
We remove loose material, correct the slope so water runs off, and recast the crown with a proper overhang and a flexible bond break.

What’s the most dangerous chimney problem in Westmont?
Flue tile cracks are the one we lose sleep over. Hot gases can reach the framing behind the masonry, and you won’t see it until it’s smoldering. Call (855) 341-3461 for a camera inspection.
Can a chimney be repaired, or do I need a full rebuild?
Most Westmont chimneys can be repaired without a rebuild. We use materials like HeatShield ceramic resurfacing for damaged flue interiors and DuraFlex liners where the original tile has failed. Rebuilds are rare and we only recommend one when the structure itself won’t hold.
Brands We Service in Westmont
We stock parts from DuraFlex, HeatShield, and Copperfield for common Westmont repairs, so most cap and crown jobs don’t wait on shipping. For liner work, we keep a range of DuraFlex sizes on hand. See our brands for the full line.
