Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Cap & Crown Across Westmont
Chimney cap and crown work in Westmont typically costs $340-$1,850 depending on whether you need a simple cap replacement or full crown rebuild, with most jobs completed in one visit. We know these post-WWII bungalows off Vermont Avenue and Century Boulevard well, the narrow lots, the shared stacks, the original brick that’s been taking seismic stress since the Eisenhower era. Call (980) 580-8641 and we’ll put a written price in front of you before any work starts, every time.
Why Emberly Chimney Cleaners Is Westmont’s Preferred Chimney Cap & Crown Company
Since 2009, our crews have run camera scans down more than 38,000 chimneys across the LA basin, and Westmont keeps us busier than most. The reason is simple: this is an unincorporated LA County community, which means there has never been a local fire marshal conducting residential chimney inspections. Most Westmont homeowners we meet have no maintenance record dating back past the original building permit. They call us because a neighbor got a chimney fire on a rare December burn night, or because an assessor flagged something during a repair review.
Every visit includes a documented photo record under Clause 4 of the Haven Standard, a practice we started years before insurers or regulators asked for it. Corrine Halstead runs our Westmont scheduling, and she makes sure every customer gets a named tech, a text when we’re on the way, and a written price, written scope, and written warranty before anyone touches brick. That’s Clause 1 of the Haven Standard: have it in writing.
Our Chimney Cap & Crown team has rebuilt crowns on hundreds of Westmont chimneys, many of which had gone untouched since the 1950s. We don’t guess at what’s wrong. We put the camera down the flue, show you the spalling brick and mortar cracks on a screen, and explain in plain terms what needs doing now versus what can wait.
Our Chimney Cap & Crown Services in Westmont
Cap Installation
An uncapped flue in Westmont is an open invitation to roof rats and European starlings, both endemic to South LA. A standard single-flue cap installation runs $340-$580 in Westmont, including the cap, fastening hardware, and a camera scan to confirm the flue below is clear. We stock Galvanized, stainless, and copper caps so we can match the cap material to the exposure on your particular street. Homes near the 110 corridor face more airborne grit than the quieter blocks west of Vermont, so we often recommend stainless in those spots. If you don’t use your fireplace, that’s exactly when we find nests, because the animals have had months of undisturbed access.
Cap Replacement
Most original Westmont caps are rusted-through galvanized units from the 1960s, or they’re simply gone. We replace a cap in Westmont for $290-$620, with the variation driven by flue diameter and whether the old fastening points have corroded into the crown. We’ll show you a photo of the old cap before you pay a dime to replace it. The job usually takes under an hour, and we caulk every seam with a high-temperature silicone rated for Southern California’s sun exposure. Your cap is the only thing between your flue and Westmont’s spring starling season.
Crown Repair
This is the big one in Westmont. The original un-reinforced masonry crowns on these 1940s-1960s chimneys develop hairline cracks from decades of LA basin seismic activity. Water gets in, the brick spalls, and the crack widens. A standard crown repair in Westmont runs $620-$1,100, depending on crown area and crack depth. We grind out the compromised mortar, apply a crown coat designed for Southern California’s wet-dry winters, and document the repair with before and after photos. If the crown is too far gone, we’ll say so plainly and quote a rebuild. We never coat over a crown that’s structurally failing.
Crown Coating
For crowns with minor spider cracking but intact structure, a full crown coating is the right call. In Westmont that runs $480-$850. We use Gelco crown coat, applied over a properly prepped surface, and we include a one-year workmanship warranty in writing. The coating sheds water, resists UV breakdown, and buys you years before a rebuild is necessary. On a 1950s bungalow where the crown is original, coating now beats replacing the whole stack later.

Common Chimney Cap & Crown Problems We See in Westmont Homes
- Shared stacks causing cross-contamination. In Westmont’s dense attached bungalows, a neighbor’s gas furnace often vents into the same chimney stack as your wood-burning fireplace. When the crown cracks or the cap fails, that exhaust backs up into your firebox. The fix is a multi-flue cap with separate terminations, which we can install on the shared stack with proper notice to the adjoining owner.
- Seismic mortar cracks in original crowns. These 1940s and 1950s chimneys were built before modern seismic codes. Hairline fractures let in winter rain and morning marine moisture, spalling brick and widening cracks. We see this on nearly every original Westmont crown we inspect.
- Animal nesting in unused flues. You burn three fires a year, maybe fewer. Starlings and roof rats move in around March and stay for months. A screened cap stops them. Without it, the nest debris blocks the flue and carbon monoxide backs into the house on the rare night you actually light a fire.
- Failing flashing at the roofline. Westmont’s low-pitch ranch rooflines mean the chimney flashing takes direct sheet flow from every winter rain. Once flashing deteriorates, water follows the chimney down into the ceiling. We check flashing on every crown and cap job, because a new cap doesn’t matter if the water is getting in four feet below it.
We serve Westmont specifically, from the blocks off Century Boulevard up to the edges of Inglewood, and we know the attached housing patterns off Vermont Avenue better than any company running calls from across the city.

FAQs - Chimney Cap & Crown in Westmont
The short answer is no, not if the job is done properly. Shared stacks in Westmont’s attached bungalows usually have separate flue lanes within one masonry structure. We’ll run a camera down your lane, confirm the partition is intact, and install a cap sized for your specific flue, not the whole stack. If the partition between flues is cracked or missing, we’ll document it with the camera and talk through options before any work starts. Call (980) 580-8641 for a written scope on your shared stack.
Crown repair is rarely an emergency, but in Westmont it’s more time-sensitive than in many other areas because the original crowns were never built with seismic movement in mind. Once water enters through those hairline cracks, the wet-dry cycle spalls brick and widens the fissure every winter. Waiting two years means a $700 repair becomes a $1,600 rebuild. If the crack is cosmetic and the crown still sheds water, you can wait. If we see moisture intrusion on the camera, schedule the repair this season. Call (980) 580-8641 and we’ll show you exactly what the crown looks like up close.
You need a cap precisely because you don’t use the fireplace. An unused flue is a stable, protected, undisturbed space, exactly what roof rats and European starlings look for. We pull nests out of Westmont chimneys every March and April, homes where the owner hasn’t lit a fire in two years. A screened cap costs $340-$580 installed and eliminates the nesting problem. The alternative is a blocked flue and carbon monoxide backing into your house the one cold night you do decide to burn. Call (980) 580-8641 for a free camera inspection and a written price.
This is one of the most common calls we get in Westmont’s attached housing, and the fix is a multi-flue cap with separately screened terminations for each flue lane. It prevents your neighbor’s furnace exhaust from riding the draft back down into your firebox. We’ll camera-scan the shared stack first to confirm the flue partition is intact, because a cap alone won’t solve cross-contamination if the masonry between the flues has failed. Most multi-flue caps in Westmont run $520-$1,100. Call (980) 580-8641 for an exact quote, and we’ll walk you through the options for your specific stack.
Since Westmont sits in unincorporated LA County, residential chimney maintenance is completely owner-driven, no one is going to send an inspector. That means the only record of your chimney’s condition is the one you create yourself. Our recommendation: get a Level 2 camera inspection every two years, keep the photo record on file, and replace caps or repair crowns the same year the camera shows a problem. We’ve seen original 1950s permits come up on Westmont properties where no one had touched the chimney since. A documented record is what insurance adjusters and future buyers actually want. Call (980) 580-8641 to get yours started, free.
