Our Chimney Cap & Crown Services in Westmont
Custom Cap Installation
Westmont’s original masonry chimneys weren’t built to standard modern dimensions. The post-WWII bungalows along streets like 94th often have odd flue sizes or multiple flues clustered tight. We measure on-site and order custom caps from Copperfield and Famco that fit without gaps or jury-rigged adapters. A proper custom cap keeps starlings and sparrows out during those long idle months, and it vents correctly when you do light a fire. Most custom installs in Westmont run $340-$620 installed.

Cap Replacement
Caps rust, blow off in Santa Ana winds, or get damaged by falling branches. On a recent call near Western Avenue, we replaced a galvanized cap that had corroded through after twelve years with a stainless multi-flue cap from Olympia Chimney. The homeowner hadn’t used the fireplace in three years and didn’t realize the cap was gone until we showed her the photo. Cap replacement in Westmont typically costs $180-$340. We carry common sizes on the truck and can often swap it same-day.

Crown Repair
The concrete crown at the top of your chimney seals the flue tiles from water intrusion. On Westmont’s 1940s-1960s bungalows, original crowns are often poured too thin or mixed with subpar concrete, and decades of LA Basin thermal cycling - rare use, mild temps, subtle expansion and contraction - cause them to crack and spall. We patch deteriorated crowns with HeatShield Crown Repair, a professional-grade refractory compound formulated for chimney exposure. Crown repair in Westmont runs $280-$480. Full rebuilds, when the crown is too far gone, range $620-$890.

Crown Coating
For crowns with minor cracking but sound structure, we apply a flexible waterproof coating that bridges hairline cracks and prevents water penetration. This is preventive work, not structural repair. In Westmont’s climate, where rain is infrequent but can come hard when it arrives, a coating buys time on a crown that’s not yet failing. Crown coating typically costs $220-$380. We’ll tell you honestly if your crown is a coating candidate or needs rebuild.

Multi-Flue Cap
Many older Westmont bungalows have two or even three flues sharing a single chimney structure - one for the fireplace, one for a former furnace or water heater. A multi-flue cap covers the entire chimney top with a single hood, eliminating the gaps between individual caps where debris collects. We source multi-flue caps from Copperfield and Famco in galvanized, stainless, or copper finishes. Installation runs $420-$740 depending on size and material.

Trusted Brands We Service in Westmont
We don’t use builder-grade substitutes. For Westmont homes, we stock and install professional-grade caps and crown materials from Olympia Chimney, Famco, and Copperfield - brands that hold up to LA County sun exposure and occasional hard rain without warping or corroding. Having these parts on hand means faster turnaround for Westmont customers. No waiting two weeks for a special order while your open flue collects debris. When we inspect your chimney, we can show you the exact cap or crown material we’ll use, explain why it fits your situation, and install it in the same visit if you approve the work.
Common Chimney Cap & Crown Problems We See in Westmont Homes
- Missing or rusted caps with bird nest accumulation. The LA Basin’s mild winters mean most Westmont fireplaces sit unused for ten or eleven months. Starlings and sparrows common to South LA find open flues irresistible. We regularly find nests packed above the damper on first-time calls - a near-standard add-on to cleaning in this neighborhood.
- Crumbled clay tile crowns from thermal cycling. Original crowns on post-WWII bungalows weren’t built to last seventy-plus years. Rare use plus mild temperature swings still cause expansion and contraction damage over decades. The crown looks intact from the ground but crumbles at the touch.
- DIY mortar patches that fail. Handy Westmont homeowners sometimes try crown repair with standard Portland cement from the hardware store. It looks fine for a season, then cracks and flakes because it lacks the flexibility and refractory properties of proper crown material. We remove the failed patch and do it with HeatShield or pour a new crown that lasts.
- Multi-flue chimneys with individual caps that don’t seal. Two or three separate caps on a shared chimney leave gaps. Debris blows in, rain finds its way to the flue tiles, and the crown underneath deteriorates faster. A single multi-flue cap solves it.

FAQs - Chimney Cap & Crown in Westmont
Yes, and this catches people off guard. Because Westmont is unincorporated LA County, not a city, chimney cap and crown permits route through LA County Building & Safety, not a municipal department. We handle the permit application as part of our service. Out-of-area contractors often miss this distinction and leave homeowners exposed to stop-work orders or failed inspections. Call (844) 418-0954 and we’ll walk you through what’s needed for your specific job.
Long idle periods combined with missing or damaged caps. Most Westmont residents use their fireplaces only a handful of nights per year, and the mild LA Basin climate means chimneys sit open and inviting to starlings and sparrows for months. By the time someone lights a fire, the nest is established and packed tight above the damper. We find this on roughly half our first-time Westmont inspections. A proper cap installation prevents recurrence.
Yes, and it’s often the better solution. Many 1940s-1960s Westmont bungalows have two or three flues in one chimney structure. Individual caps leave gaps; a single multi-flue cap from Copperfield or Famco covers the entire top, keeps all flues clear, and protects the crown underneath. We measure on-site and can typically install same-day or next-day.
No. Standard mortar or cement lacks the flexibility and refractory properties to handle chimney thermal cycling. DIY patches look fine for a season, then crack, flake, and trap moisture against the flue tiles. We’ve removed dozens of failed homeowner patches in Westmont. Crown repair requires professional-grade material like HeatShield Crown Repair, or a full pour with proper slope and overhang. The cost of doing it twice always exceeds doing it once with the right material.
Most crown rebuilds with cap installation are completed in four to six hours on a single visit. We arrive with materials, set up containment, remove the failed crown, pour or apply the new crown material, and install the cap. For Westmont’s typical single-family bungalows, there’s rarely a need for a second trip. Call (844) 418-0954 to schedule - estimates are free, and we’ll confirm the timeline when we see your chimney.
On a 1950s bungalow on 94th Street, we found a crown cracked wide open and a missing cap; a family of starlings had packed the flue with nesting material above the damper. We installed a custom multi-flue copper cap from Copperfield, patched the crown with HeatShield Crown Repair, and cleared the nest - one trip, done right for a self-reliant homeowner who didn’t want callbacks. That’s how we work in Westmont.
