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 comes down to one recurring situation: the city’s 1950s and 1960s ranch homes still have their original masonry fireplaces, and the clay tile liners inside them are now 50 to 70 years old. Those liners crack. Mortar joints fail. Water gets in through crowns that weathered decades of San Gabriel Valley sun, and by the time a homeowner notices, the flue needs real repair, not a sweep. We handle the full stack: chimney repair, sweeping, and dryer vent cleaning. If you’re seeing spalling brick or suspect a cracked flue, call Chestnut Chimney Sweep at (855) 360-4975.
Why Covina Homes Are Different
The housing stock in Covina tells you exactly what to expect inside the chimney. Most of the city is single-story tract ranches built between 1955 and 1975, when developers converted the old citrus groves into subdivisions. Those homes got brick masonry fireplaces with clay tile liners, and a lot of those originals are still in service. Clay tile does fine for a few decades, but the heating and cooling cycle of Covina’s climate works against it. The summer heat bakes the exterior masonry, and when the fireplace finally gets used in winter, the liner expands and contracts. After 60 years of that, hairline cracks turn into gaps, and gaps become fire hazards.
We also see a lot of homes near downtown Covina from the 1920s through the 1940s. Those chimneys are older still, often built with softer mortar and shallower footings. In the Santa Ana wind season, debris works its way into uncapped flues, and birds take advantage of dormant chimneys during the long dry months. A chimney that sits unused from April to November in Covina is a chimney where squirrels, chimney swifts, or pigeons have had time to build nests. That’s a specific problem for this climate, and it’s why we recommend a cap inspection as part of any sweep or repair call.
Styles & brands we work with





Our Main Covina Services
Most Covina homeowners call us first about one of two things: a chimney that hasn’t been cleaned in years, or a dryer vent that’s taking longer and longer to finish a load. Both are combustion-safety issues, and both are jobs we handle in one appointment.
Chimney Sweep in Covina
A sweep here usually means more than removing soot. In Covina’s older ranches, we’re looking at 60-year-old clay liners while we clean, which means the sweep doubles as an inspection. We check for cracked tiles, nesting material from the off-season, and creosote buildup that’s heavier than what you’d find in a newer fireplace. If you’ve converted to a gas log set, the combustion profile changes and the deposits are different, so the sweep has to be adjusted accordingly. For the full breakdown of what a sweep includes in Covina, see our Chimney Sweep in Covina page.

Dryer Vent Cleaning in Covina
Dryer vents in Covina’s older homes are often original to the house, which means 30 to 40 feet of galvanized pipe with a few elbows and a lot of lint. The dry air means lint gets brittle and packed in tighter than you’d see in a humid coastal climate, and when the Santa Anas blow, dryer vents backdraft and push that lint back toward the appliance. We treat dryer vent cleaning as a fire-safety service, not an add-on, and we bring the same parts knowledge to venting that we bring to chimneys. Details are on our Dryer Vent Cleaning in Covina page.

Chimney Repair in Covina

Chimney repair in Covina almost always starts with the liner. The original clay tiles in a 1960s ranch have been through 60 summer heat cycles and 60 winters of on-and-off use, and by now, most of them show some degree of cracking or joint separation. When we open up a Covina chimney for the first time, the most common finding is spalling at the flue tile joints, often combined with a crown that’s lost its slope and is holding water against the brick. That’s the exact situation that calls for a real repair, not a sweep-and-hope. We start every repair with a camera inspection so you can see the damage yourself before anyone quotes a liner or a cap.
Everything we install comes from professional-grade lines: Chimney Repair work in Covina uses DuraFlex liners, HeatShield restoration, Gelco sealants, or Olympia Chimney caps and arrestors depending on what the system needs. We specify the part by name because the part matters as much as the labor. If a handyman would put in a generic cap from a hardware store, we’d rather put in a Copperfield or Olympia cap sized correctly for the flue and rated for the fuel type.
Chimney Liner Installation
Signs you need it
You need a liner replacement when a camera inspection shows cracks wider than a hairline, gaps between clay tiles, or missing tile sections that expose the masonry behind them.
What it costs in Covina
Liner installation in Covina typically runs $2,500 – $5,000 depending on flue size, roof access, and whether the old clay tiles need to be broken out first.
How we do it
We camera the flue first, break out or prep the old clay tile if required, then size and run a DuraFlex stainless liner from the firebox to the crown with a proper top plate and cap.
Chimney Crown Repair
Signs you need it
A cracked or spalled crown is usually visible from the ground as a crumbling mortar surface at the top of the chimney, often with water staining on the brick below it.
What it costs in Covina
Crown repair in Covina typically runs $400 – $1,000 when caught early, but a full rebuild on a badly deteriorated crown can reach $1,500.
How we do it
We form and pour a new concrete crown with a proper drip edge and slope to shed water away from the flue, or we apply a Gelco CrownCoat system when the existing crown is structurally sound but surface-cracked.
Chimney Flashing Repair
Signs you need it
Leaking around the roofline after rain, water stains on the ceiling near the chimney, or a visible gap between the flashing and the chimney stack are the usual warnings.
What it costs in Covina
Flashing repair in Covina typically runs $300 – $600 for a section repair and $800 – $1,500 if the flashing has to be cut out and replaced completely.
How we do it
We cut back the old flashing, install step and counter-flashing with a proper overlap, and seal the termination bar with a polyurethane sealant rather than roof cement that dries out in Covina’s heat.
Chimney Cap Installation
Signs you need it
You need a cap when you hear animals in the flue after the dry season, when rain comes straight down into the firebox, or when you see daylight from inside the firebox looking up.
What it costs in Covina
Cap installation in Covina typically runs $250 – $600 for a standard stainless cap on a single flue, with multi-flue and custom sizes running higher.
How we do it
We measure the flue dimensions, choose an Olympia Chimney or Copperfield cap with a spark arrestor and proper screen sizing for your fuel type, and secure it to the crown with masonry fasteners and sealant.
What Chimney Repair Costs in Covina
| Item | Typical range in Covina |
|---|---|
| Chimney liner installation | $2,500 – $5,000 |
| Crown repair | $400 – $1,000 |
| Flashing repair | $300 – $1,500 |
| Cap installation | $250 – $600 |
Is a HeatShield restoration better than a full liner replacement in Covina?
Yes, when the damage is surface-level. HeatShield is a ceramized coating we apply to an existing clay liner that’s still structurally sound. It seals cracks and restores the flue for a fraction of the cost of a full DuraFlex liner, and it’s a repair most Covina homes qualify for after inspection.
Do I really need a new liner, or can I just get the chimney swept?
A sweep only removes flammable creosote. If your Covina chimney has cracked clay tiles, sweeping won’t fix the crack and the fireplace is still unsafe to burn. We camera every flue before recommending a liner, and we’ll show you the footage so you can make the call based on what you see, not what we tell you. Call (855) 360-4975 to set up an inspection.

What pushes a Covina chimney repair toward the high end is access. Steep rooflines on some of the 1960s ranches and older downtown homes make ladder work slower, and two-story additions in the 91723 area add setup time. The price we quote is the price you pay: we agree on the scope before work starts, and we don’t pad the final bill with surprise line items.

— Javier Garcia"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."
