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 West Covina, CA
Chimney repair in West Covina usually means one of two things: a cracked crown letting rain into a 1960s masonry fireplace, or a clay liner that has finally given out after decades of heat cycling. Ontario Chimney handles both, and everything between. We’ve worked on the original brick fireplaces in the 91790 and 91791 tract homes long enough to know exactly what fails first and what can safely wait. If you’re seeing water stains, crumbling mortar, or white staining on the brick, call (833) 467-7685 and we’ll tell you what’s actually going on.
Why West Covina Homes Are Different
Most of West Covina’s housing stock went up between the 1950s and 1970s, which means original masonry fireplaces with clay tile liners. Those liners were built to a looser standard than anything installed today, and after fifty or sixty years of heat, rain, and the occasional chimney fire, they crack. The 91790 and 91791 ZIP codes especially are full of post-WWII tract homes where the fireplace has never been relined, and cracked mortar joints are common enough that we expect to see them on nearly every inspection we do in Shadow Oak and the neighborhoods around Delhaven Park.
Climate matters here too. West Covina sits in the San Gabriel Valley, downwind of the Angeles National Forest. Santa Ana winds push wildfire ash and fine debris into chimneys, and that ash settles into creosote that’s already gone hard and glassy from the city’s long dry spells. A fireplace that only gets lit during cold snaps still accumulates that crust, and it doesn’t brush out easily. The newer infill homes in 91792 with prefabricated metal fireplaces need a different cleaning approach entirely, and we adjust for that on every job.

Our Main West Covina Services
Most West Covina homeowners call us first about two services: a chimney sweep they can schedule before burning season, and dryer vent cleaning after a lint buildup scare or a slow-drying cycle. Both are maintenance work with direct safety consequences.
Chimney Sweep in West Covina
A chimney sweep in West Covina has to account for what Santa Ana winds leave behind. We remove the creosote, but we also clear spark arrestors clogged with brush-fire ash and check for any debris that’s blown down an uncapped flue. The original fireplaces in the 91790 tract homes often have flues that were never designed for today’s heat output, so we check for the hairline cracks that hard creosote hides. Full details are on the Chimney Sweep in West Covina page, including what we inspect during every sweep and what it costs.
Dryer Vent Cleaning in West Covina
Dryer vents in West Covina run through attics that bake in the San Gabriel Valley heat, and that heat speeds up how fast lint hardens inside the duct. Longer vent runs in the single-story tract homes mean more surface area for lint to collect, and every extra foot adds resistance. We clean the full run from dryer to exterior termination, not just the first few feet behind the machine. The Dryer Vent Cleaning in West Covina page walks through our process and how to know when the vent is overdue.

Chimney Repair in West Covina
Chimney repair in West Covina is usually structural, not cosmetic. Homes built in the 1960s and 1970s sit on clay tile liners that have absorbed decades of thermal stress, and the combination of dry summers, occasional hard rain, and Santa Ana-driven ash means cracks widen faster than homeowners expect. We’re the Chimney Repair team that handles the full scope, from a simple crown recoat to a full HeatShield resurfacing or DuraFlex reline, without handing you off to a general contractor who doesn’t know flues. When we repair a chimney in West Covina, you see the camera evidence before we recommend anything, and we’ll tell you plainly when a repair can wait.
Chimney Cap Installation
Signs you need it
Water pooling in the firebox after rain, rust streaks below the flue, or visible debris inside the chimney.
What it costs in West Covina
Chimney cap installation in West Covina typically runs $280 to $525 depending on flue size and cap type.
How we do it
We measure the flue opening, select a cap with the right mesh and clearance for your fireplace type, secure it to the crown with a weather-tight seal, and confirm draw before we leave.
Chimney Cap Replacement
Signs you need it
A rusted-through cap, missing mesh, or a cap that has blown off entirely during a Santa Ana event.
What it costs in West Covina
Replacing an existing cap in West Covina costs $280 to $475, including removal of the old one and disposal.
How we do it
We remove the old cap, inspect the crown underneath for cracking, install the new cap with mechanical fasteners and sealant, and test for proper airflow.
Chimney Liner Installation
Signs you need it
Cracked or spalling clay tile visible during a camera inspection, smoke backing into the house, or a liner that hasn’t been touched since the home was built in the 1960s.
What it costs in West Covina
Chimney liner installation in West Covina runs $2,800 to $6,500 depending on flue length, access difficulty, and whether we use a DuraFlex stainless steel system or HeatShield resurfacing.
How we do it
We run a camera through the flue to map cracks and offsets, then either install a DuraFlex flexible liner sized to the flue or apply HeatShield ceramic coating, depending on what the condition calls for.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the chimney, damp drywall in the attic, or visible rust and gaps at the roof line.
What it costs in West Covina
Chimney flashing repair in West Covina typically costs $450 to $950, depending on whether we’re resealing existing flashing or cutting in new step flashing at the roof intersection.
How we do it
We remove the old flashing, inspect the roofline and chimney masonry underneath, install new step flashing with proper overlap, and seal the joint so rain can’t track under the shingles.
Chimney Crown Repair
Signs you need it
Cracked or spalling crown mortar, pieces of concrete in the gutter after storms, or water pooling on top of the chimney.
What it costs in West Covina
Chimney crown repair in West Covina runs $350 to $850, depending on the size of the crown and how much of the old surface needs removal before the new coat goes on.
How we do it
We grind or strip the deteriorated crown surface, build up the mortar or apply a proper crown coat with an overhang drip edge, and smooth it so water runs off instead of sitting against the flue tile.
What Chimney Repair Costs in West Covina
| Item | Typical range in West Covina |
|---|---|
| Chimney cap installation | $280 – $525 |
| Chimney cap replacement | $280 – $475 |
| Chimney liner installation | $2,800 – $6,500 |
| Chimney flashing repair | $450 – $950 |
| Chimney crown repair | $350 – $850 |
Do I need a new liner, or can the old one be repaired?
If the cracks are superficial and the flue is otherwise sound, HeatShield resurfacing can restore it for less than a full tear-out. If the clay tile is spalling or the flue has offset sections that a rigid liner can’t navigate, a DuraFlex stainless liner is the answer. We show you the camera footage before recommending either one.
How long does a chimney repair job take in West Covina?
Cap and crown work is usually done in a single visit. A full liner installation or HeatShield resurfacing takes one day in most West Covina homes, with a short curing period before you light the first fire. Call (833) 467-7685 and we’ll give you a realistic timeline for your specific chimney.
Brands We Service in West Covina
We install and service parts from Copperfield, DuraFlex, HeatShield, and Gelco.

What West Covina Customers Say
