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 Ontario, CA
Chimney repair in Ontario, CA usually comes down to two things: cracked clay tile liners in 1950s and 1960s tract homes, and caps or crowns that have failed after decades of Inland Empire sun. Ontario Chimney has served Ontario since 2014, and we handle the full repair scope, from a simple crown patch to a complete DuraFlex liner replacement. Most Ontario chimneys were built for occasional recreational fires, not daily heating, so repairs here tend to be less urgent than in colder markets, but they still need to be done right. Call (833) 467-7685 when you want an honest assessment backed by camera evidence.
Why Ontario Homes Are Different
Ontario’s post-war housing boom, much of it built by developer Henry N. Lash, produced thousands of single-story stucco tract homes with original brick fireplaces and clay tile flues. Those flues are now 50 to 70 years old, and clay tiles crack. In Ontario, the long, hot dry season means chimneys sit unused from April through November, giving birds, rodents, and wind-blown debris time to settle in. We routinely pull palm fronds and tumbleweeds out of uncapped flues in the neighborhoods near Euclid Avenue.
The Inland Empire’s Santa Ana winds add another layer. Strong downdrafts can push soot and ash into living rooms when the damper isn’t sealed, and they carry debris that clogs flues faster than many homeowners expect. Summer heat expansion is also hard on mortar crowns, which crack and let water into the brickwork. None of this is unique to Ontario, but the combination of aging tract housing, long idle seasons, and wind events shapes every repair we quote here.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: the fireplace hasn’t been swept in years and they want to use it safely, or the dryer vent is clogged and the dryer takes two cycles to finish a load. Both are core services here.
Chimney Sweep in Ontario
A chimney sweep in Ontario isn’t usually an emergency. Because most fires here are occasional and recreational, creosote buildup tends to be moderate. What we find more often is debris: bird nests, bee hives, palm fronds, and wind-blown trash that settled during the long off-season. We sweep the full flue, remove the debris, and inspect the liner and crown while we’re in there. If you haven’t had the chimney looked at in a few years, start with a full sweep and inspection. Chimney Sweep in Ontario walks through what’s included and what it costs.
Dryer Vent Cleaning in Ontario
Dryer vent cleaning matters in Ontario because lint fires don’t care whether a house is old or new. Single-story tract homes often have short interior dryer vent runs, which sounds good until you realize the lint builds up right behind the dryer where nobody looks. We clean the full run from the dryer to the exterior termination, remove the built-up lint, and check the vent cap. The NFPA attributes thousands of dryer fires each year to lint accumulation, and most of them are preventable. Dryer Vent Cleaning in Ontario covers the details.

Chimney Repair in Ontario
Chimney repair in Ontario usually starts with a cracked liner or a failed crown. The clay tile flues in Ontario’s 1950s and 1960s tract homes were never designed to last 70 years, and the Inland Empire’s summer heat expansion accelerates cracking. A cracked liner lets combustion gases and heat reach the surrounding masonry, and in a wood-framed tract home, that’s a fire risk you don’t want to carry. We inspect every chimney with a camera before recommending any repair, and we’ll show you the footage. Our Chimney Repair service covers everything from a simple cap to a full reline.
Chimney Cap Installation
Signs you need it
You hear birds or bees inside the flue, you find debris or animal droppings in the firebox, or rainwater leaks into the firebox after storms.
What it costs in Ontario
A chimney cap installation in Ontario runs $250 to $500 depending on the flue size and cap material.
How we do it
We measure the flue tile, set the cap with a weatherproof seal so it stays put in Santa Ana winds, and confirm the mesh keeps birds and embers out.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, the mesh is torn, or wind has bent the brackets so the cap sits loose or rattles.
What it costs in Ontario
A replacement cap in Ontario costs $200 to $500 installed, with the old cap removed and disposed of.
How we do it
We pull the old cap, check the flue tile for damage underneath, and install a new Galvalume or stainless cap in the correct size with a secure mechanical fit.
Chimney Liner Installation
Signs you need it
Your camera inspection shows cracked or missing clay tiles, you see white staining or efflorescence on the chimney exterior, or smoke backs up into the room.
What it costs in Ontario
Installing a DuraFlex stainless steel or aluminum liner in Ontario generally runs $2,500 to $5,000, which includes the liner, insulation, and top plate.
How we do it
We measure the flue, select the correct DuraFlex liner diameter, drop the liner through the chimney, connect it at the appliance and the cap, and verify draft with a smoke test.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling near the chimney, damp drywall around the fireplace, or dark streaks on the roof where the chimney meets the shingles.
What it costs in Ontario
Flashing repair in Ontario typically costs $350 to $800, less if it’s a simple reseal and more if the flashing is rusted or torn and needs full replacement.
How we do it
We remove the damaged flashing, inspect the underlayment, and install new step and counter flashing sealed with a high-temperature roofing sealant that holds up in the summer sun.
Chimney Crown Repair
Signs you need it
You see cracks in the concrete or mortar crown on top of the chimney, or water is getting into the masonry and causing spalling bricks.
What it costs in Ontario
Crown repair in Ontario runs $300 to $900, with full crown replacement running higher if the existing crown is crumbling.
How we do it
We clean out loose material, apply a flexible CrownCoat sealant or recast the crown with a proper overhang and drip edge, and let it cure before exposure to rain.

The biggest price variable in Ontario is roof access. Single-story tract homes with a low pitch are easier to work on than two-story additions or steep roofs, and that shows up in the labor. Whatever the job, we quote it flat before we start, so the number on the proposal is the number on the invoice.
