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 Covina, CA
Chimney repair in Covina usually means one of two things: a clay-tile liner from a 1960s tract home that’s finally spalling apart, or a chimney cap that let in rain, birds, and a decade of valley oak debris. Walnut Chimney has served Covina since 2017, and the pattern is consistent across the 91722 and 91723 ZIPs. The fireplaces were built well, but they’re sixty years old now, and the flues were never designed for sixty years of San Gabriel Valley heat cycling. Call (855) 341-3461 when you need a straight answer about yours.
Why Covina Homes Are Different
Covina’s core neighborhoods, the 1950s through 1970s tracts that spread across 91722 and 91723, were built when masonry fireplaces were standard equipment. Original clay-tile liners are the rule, not the exception. Those liners crack. They crack from decades of heating and cooling, from the moisture that seeps through crowns that have lost their seal, and from the simple passage of time. When they crack, the flue stops doing its one job: keeping heat and combustion gases inside the chimney and away from the wood framing around it.
The hillside pockets in 91724 tell a different story. Homes there from the 1980s and 1990s often have prefab metal fireboxes with factory flues. Those systems age differently. They warp, they rust at the seams, and their caps fail in ways that let the Santa Ana winds push debris straight down the pipe. When the winds knock out power and a Covina homeowner lights the first fire of the season, the flue has to work immediately. A dormant chimney with a cracked liner or a blocked flue doesn’t recover gracefully. It smokes, it backdrafts, and sometimes it sends embers where they don’t belong.
Styles & brands we work with
Our Main Covina Services
Most Covina calls start with a sweep or a dryer vent concern, and many uncover repair work that needs a deeper look.
Chimney Sweep in Covina
In Covina, a sweep call often follows a long period of disuse. The fireplace sat empty through the summer, then through the first cool weeks of fall, and the first cold night after Thanksgiving turns a homeowner into a chimney customer. What our technicians find in Covina flues is predictable: creosote from last winter’s occasional fires, soot that has compacted inside the smoke chamber, and nests. The valley oaks and eucalyptus trees around the older tracts make chimney caps a target every spring, and a flue that hasn’t been swept in five or ten years can hold more nest material than creosote. A sweep is the baseline service that tells us what’s actually happening up there. See Chimney Sweep in Covina for the full breakdown.
Dryer Vent Cleaning in Covina
The fire hazard most Covina homeowners never think about is the dryer vent, and the 1950s ranches of 91722 are notorious for it. Long, cramped vent runs that snake through interior walls and dump lint into the attic or crawlspace, often with flexible foil duct that has sagged and filled with debris. Dryer lint is the fuel that makes these vents a real fire risk, and the NFPA has named dryers a leading cause of home fires. We treat dryer vent cleaning as a core safety service, not an add-on, because it belongs in the same conversation as the chimney. See Dryer Vent Cleaning in Covina for pricing and specifics.

Chimney Repair in Covina
Chimney Repair in Covina is what happens when a sweep reveals structural damage, and in this city it usually traces back to the liner. The original clay tiles in a 1960s masonry chimney were fired in a kiln and assembled in sections, and they were never meant to last sixty years of intermittent heat followed by long idle stretches. When the first power outage of winter hits and the Santa Anas are blowing, a family lights a fire in a chimney that has a cracked liner, a failed cap, and maybe a squirrel nest packed into the smoke shelf. The sweep clears the debris. The repair is what keeps the house safe afterward. From the firebox to the cap, we repair what we find, and we use the right material for the specific failure rather than forcing a one-brand fix.
Chimney Liner Installation
Signs you need it
Flakes of clay tile in the firebox, visible cracks in the flue during a camera inspection, smoke backing into the house on windy days, or a sweep noting spalling tiles that mean the flue is shedding its interior surface.
What it costs in Covina
A full stainless steel liner installation in Covina typically runs $2,400 to $5,000, depending on flue height, access from the roof, and whether the old clay tiles need to be broken out to make room for the new liner.
How we do it
We size the flue, run a camera inspection to document the condition, specify a DuraFlex stainless liner if the chimney is a good candidate, and install it through the existing masonry chase with proper insulation and top-plate termination.
Chimney Cap Installation
Signs you need it
Rain water inside the firebox, bird or squirrel sounds in the chimney, visible rust around an old cap, or a flue that sits wide open to the sky with no termination at all.
What it costs in Covina
A standard stainless steel cap with screening runs $250 to $650 installed, and the price moves with the flue size, roof pitch, and whether we’re replacing a rusted-out cap that needs old hardware removed.
How we do it
We measure the flue opening, select a copper or stainless cap from our stock of Famco and Olympia parts, secure it to the flue tile, and make sure the screen mesh is tight enough to keep Covina’s squirrels and starlings out for good.
What Chimney Repair Costs in Covina
| Item | Typical range in Covina |
|---|---|
| Chimney liner installation (stainless) | $2,400 – $5,000 |
| Chimney cap installation | $250 – $650 |
| Chimney crown repair or rebuild | $750 – $1,800 |
Do I really need a new liner, or is the sweep just trying to sell me work?
You will see the camera footage yourself. We do not recommend a liner replacement on a hunch. If the clay tiles are cracked, spalling, or missing in sections, the flue is compromised and needs to be relined before you burn again.
What actually happens if I keep using a chimney with a cracked liner?
Heat and gases reach the masonry and framing around the flue. That can ignite creosote inside the chimney cavity where a sweep cannot reach it. A cracked liner is not a cosmetic problem. It is the primary barrier between the fire and the house. Call (855) 341-3461 for an exact quote.

What Covina Customers Say
"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
— Renee Mercer"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."
— Justin Nguyen"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
