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 starts with a crown that’s been quietly failing for years or a clay tile liner that’s cracked somewhere you can’t see from the living room. Most of the homes here were built between the 1920s and 1950s, and their original masonry chimneys have now outlived several roofing cycles without matching attention. Sherwood Chimney Sweep has served Westmont since 2017, and we see the same pattern on nearly every street: deferred maintenance, not heavy use, is what finally forces the call. If you’re seeing water stains near the fireplace or hearing birds inside the flue, call (833) 589-8498 for a straight diagnosis.
Why Westmont Homes Are Different
Westmont sits in the South Bay’s pre-war and postwar single-family belt, where nearly every tract home was built with a brick or masonry fireplace. The catch is that the region’s mild weather means those fireplaces get used a handful of nights a year, not as primary heat. So chimney cleaning here is less about heavy creosote loads and more about what happens when a structure sits unused for months at a time: cracked crowns, missing caps, and pest intrusion in the flue.
The neighborhood is dominated by 1920s to 1950s stucco-over-wood or brick bungalows and early ranch homes, typically with original masonry fireplaces and clay tile liners. Many have been remodeled with enclosed gas inserts or freestanding stoves that still vent through the old flue, which creates a specific problem: the liner that was adequate for an open wood fire may be oversized or deteriorating for a modern gas appliance’s exhaust profile. Westmont’s coastal-influenced climate is mild and dry with almost no freezing, but the occasional winter rain and persistent marine layer create conditions where moisture can weaken mortar and rust dampers. Dry, windy fall days bring debris and bird nests into uncapped chimney tops.
In Westmont, a technician who doesn’t look up will miss the most common call: chimney swifts and squirrels nesting in uncapped flues on the older bungalows along the neighborhood’s interior streets. It spikes every spring when residents first light a fire and get smoke backing into the living room. That’s rarely a cleaning problem. It’s an animal-in-the-flue problem, and it requires removal plus the cap installation that should have been there all along.
Styles & brands we work with
Our Main Westmont Services
Most Westmont homeowners call us for one of two reasons: the chimney hasn’t been swept in years and they’re finally using the fireplace again, or the dryer vent has never been inspected and the dryer is taking forever to finish a load. Both are fire-prevention services at their core, and we handle both under one roof.
Chimney Sweep in Westmont
A sweep in Westmont typically unearths more than creosote. We remove soot and glaze buildup, but we also document what we find: cracked flue tiles, deteriorated mortar joints, a rusted damper that won’t open fully. The mild climate means many of these fireplaces have gone a decade without service, and the first sweep after that long a gap is really an assessment. We use a camera to show you exactly what’s inside before anyone recommends more work. Full details are on our Chimney Sweep in Westmont page.
Dryer Vent Cleaning in Westmont
Dryer vents in Westmont’s older homes are often short, straight runs that have never been opened since installation. Lint builds up in the pipe, restricts airflow, and drives up drying times while creating the leading cause of household dryer fires. We clean the full run from dryer to exterior termination, inspect the duct for damage or improper material, and confirm the flap outside opens properly. It’s the same fire-prevention standard we apply to chimneys. See our Dryer Vent Cleaning in Westmont page for the full scope.

Chimney Repair in Westmont
Chimney repair in Westmont is driven by the age of the housing stock and the coastal moisture that works on mortar year after year. Most homes here still have their original clay tile liners, and once those tiles crack, the chimney isn’t safe to use until it’s addressed. Sherwood Chimney Sweep handles everything from cap installation and flashing repair to full liner restoration or replacement, using professional-grade materials from names like DuraFlex and HeatShield, not hardware-store substitutes. For a broader look at what repair involves, start with our Chimney Repair service hub.
Chimney Cap Installation
Signs you need it
You hear birds or animals inside the chimney, or you find nesting debris and leaves at the bottom of the firebox.
What it costs in Westmont
Chimney cap installation in Westmont typically runs $200 to $600 depending on the cap style and whether the flue tile needs a custom bracket to seat properly.
How we do it
We measure the flue opening, install a stainless steel or copper cap sized to the tile, and secure it with mechanical fasteners that hold in Westmont’s dry fall winds.
Chimney Crown Repair
Signs you need it
The concrete crown at the top of the chimney has visible cracks, is spalling, or has separated from the flue tile, letting water seep into the masonry below.
What it costs in Westmont
Chimney crown repair in Westmont typically costs $500 to $1,300, with the higher end covering a full recast rather than a surface patch.
How we do it
We remove the deteriorated crown material, build or patch the form to slope water away from the flue, and apply a proper waterproof sealant so Westmont’s winter rain can’t start the cycle over.
Chimney Liner Installation
Signs you need it
The clay tiles inside the flue are cracked or missing, the chimney fails a level 2 inspection, or you’re switching to a gas insert that requires a properly sized liner.
What it costs in Westmont
Chimney liner installation in Westmont runs $2,300 to $9,000, a range that reflects whether it’s a straightforward flexible liner pull or a full tear-out and rebuild of the clay tile system.
How we do it
We run a camera inspection first to confirm the damage, then pull a DuraFlex flexible liner sized to your appliance and fuel type, insulating where code requires it.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling near the chimney chase, or the flashing at the roofline has pulled away, rusted through, or was patched with roofing cement that’s now cracked.
What it costs in Westmont
Chimney flashing repair in Westmont typically runs $350 to $900, and we always replace with new metal rather than layering more sealant over a failed patch.
How we do it
We remove the old flashing, cut step and counter flashing to match the roof pitch, and tie it into the masonry so water sheds away from the chimney penetration.
What Chimney Repair Costs in Westmont
| Item | Typical range in Westmont |
|---|---|
| Chimney cap installation | $200 – $600 |
| Chimney flashing repair | $350 – $900 |
| Chimney crown repair | $500 – $1,300 |
| Chimney liner installation | $2,300 – $9,000 |
Do I have to replace my clay tile liner, or can it be restored?
Not always. If the tiles are cracked but not structurally collapsed, HeatShield ceramic resurfacing can restore the flue from the inside without a full tear-out, typically for less than half the cost of a liner replacement. Restore before you replace is the principle we follow when the damage is still contained.
Can you fix a chimney crown without rebuilding the whole chimney?
Yes, crown repair is localized to the top of the chimney and rarely involves the structure below. If the crack network is isolated, we patch and seal; if the crown is broken into sections, we recast it. Either way, the masonry below usually stays untouched.

What Westmont Customers Say
"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Jodi Parker"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
— Ruben Flores"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
— Nabil Saleh
