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
Most of the chimney work we do in Ontario falls into one of two buckets: the October-to-December first-fire rush, and what we find after a Santa Ana wind event. The city’s housing stock skews heavily toward 1950s through 1980s single-story tract homes, and many of those still have factory-built metal fireplaces or masonry fireboxes that have been through decades of Inland Empire heat, wind, and dry air. The real demand here isn’t heavy wood-burning season wear. It’s creosote and soot from light intermittent use, wind-driven debris, bird and animal nesting, and rusted or missing caps and spark arrestors. Corona Chimney Sweep has served Ontario since 2018, and we repair what we find. If you’re looking at a liner that’s spalling, a crown that’s cracked, or a cap that gave up during the last windstorm, call (855) 382-6159 and we’ll give you a straight answer.
Why Ontario Homes Are Different
Ontario sits at the western edge of the Inland Empire where the Santa Anas come through hard in the fall. That wind is the single biggest driver of chimney problems we see across ZIP codes 91762, 91764, 91798, and 91758. After a wind event, our techs routinely find caps packed with palm fronds, eucalyptus debris, and fine dust, and more than a few uncapped flues with a bird working on a nest. The thermal cycling matters too: Ontario summers run hot and dry, and the repeated expansion and contraction of masonry crowns and metal caps in that heat is what causes hairline cracks to open up and get worse year over year.
The housing stock compounds this. Much of Ontario is postwar and late-20th-century tract construction, predominantly single-story stucco homes. A lot of those fireplaces were built with the original spark arrestors and screens, and we still find those on service calls: rusted, loosened, or hanging by one screw. The fireplaces themselves mostly burn decorative Duraflame logs a handful of nights a year, which means the creosote load is lighter than a snowbelt chimney, but the soot and debris accumulation from intermittent use, plus months of disuse in the summer, still needs to be cleaned before the first fire of the season.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a chimney sweep before burning season, or a dryer vent cleaning once they realize their vent hasn’t been touched in years. Both are fire-prevention work at the core.
Chimney Sweep in Ontario
A proper sweep in Ontario removes creosote, soot, and whatever the Santa Anas have pushed into the flue since last season. In most of the tract homes we service, that means pulling the cap, running a brush down the flue, and checking the smoke chamber and damper while we’re in there. We also look at the cap and screen because those take a beating from wind and rust in this climate. For a full breakdown of what’s included and what it costs in Ontario, see our Chimney Sweep in Ontario page.
Dryer Vent Cleaning in Ontario
A clogged dryer vent is a fire waiting to happen. Lint buildup inside the vent restricts airflow, the dryer runs hotter, and the ignition source is right there. We treat dryer vent cleaning as a fire-prevention service on equal footing with chimney work, and the same technicians who are trained in combustion venting do the job. In Ontario’s summer heat, a restricted dryer vent also pushes hot, humid air back into the house, which no one wants in July. For specifics on how we clean vents and what to expect, see our Dryer Vent Cleaning in Ontario page.

Chimney Repair in Ontario
Chimney repair in Ontario is usually a story about wind, heat, and age. Most of the calls we get are from homeowners whose cap blew loose or rusted through, whose flashing is leaking around the roofline during winter rains, or whose mortar crown has cracked open from years of thermal cycling. Because this is a tract-home market with miles of single-story stucco construction, the chimneys are often simple and low, which means the repairs are usually straightforward once we get eyes on the actual problem. We don’t refer repair work to another company, and we don’t recommend a liner replacement without camera evidence you can see for yourself. We stock and install materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, which means the repair gets done with the same lines professional chimney contractors source. For the full scope of what we repair, see our Chimney Repair page.
Chimney Cap Installation
Signs you need it
You can hear or see birds or debris getting into the flue, or you have no cap at all and rain is coming down the chimney.
What it costs in Ontario
Chimney cap installation in Ontario typically runs $160 to $240 for the cap and mounting hardware, with labor varying based on roof access and flue size.
How we do it
We measure the flue, set a stainless or galvanized cap rated for your chimney type, secure it to the flue tile or crown, and verify the draft before we leave.
Chimney Cap Replacement
Signs you need it
Your existing cap is rusted through, dented, missing sections of mesh, or no longer sitting flush on the flue.
What it costs in Ontario
Chimney cap replacement in Ontario typically costs $160 to $240 for a new cap, plus removal of the old one and any minor crown patching needed to seat it properly.
How we do it
We remove the old cap, clean the flue rim, install a properly sized replacement, and check that the mesh and lid are intact and secure.
Chimney Liner Installation
Signs you need it
Your existing clay tile liner has cracked, spalled, or separated, or you’re converting an appliance and the current flue is no longer safe or code-compliant.
What it costs in Ontario
Chimney liner installation in Ontario ranges from $2,900 to $4,700 depending on flue height, access, and whether we’re relining an existing chimney or running an insulated liner for a new appliance.
How we do it
We size the flue, run a DuraFlex stainless flexible liner down the chase, insulate it where code requires, and connect and secure it at the appliance and termination points.
Chimney Flashing Repair
Signs you need it
You have water staining on the ceiling or wall around the chimney after rain, or the flashing metal is visibly lifted, rusted, or pulling away from the roofline.
What it costs in Ontario
Chimney flashing repair in Ontario typically runs $250 to $800 depending on how much of the flashing is compromised and whether we need to remove and reset shingles or tile around it.
How we do it
We remove the damaged flashing, inspect the underlayment, install new step and counter flashing sealed with an exterior-grade sealant, and confirm water is shedding away from the penetration.
Chimney Crown Repair
Signs you need it
The mortar crown on top of the chimney has visible cracks, is spalling or crumbling, or water pools on it instead of running off.
What it costs in Ontario
Chimney crown repair in Ontario typically ranges from $400 to $1,300 depending on the size of the crown, the extent of the cracking, and whether a full recast is needed.
How we do it
We clean and prep the existing crown, fill and seal cracks with a flexible crown sealant, or recast the crown entirely with a properly sloped mortar mix that sheds water away from the flue.

Do I really need a new liner, or can the existing one be repaired?
Not every cracked liner needs full replacement. For chimneys with deteriorated mortar joints or hairline cracks but an otherwise sound structure, we may be able to use a HeatShield resurfacing system to restore the flue interior without tearing anything out. We’ll show you the camera footage before we ever recommend the scope of work. Call (855) 382-6159 for an exact assessment.
How much does chimney repair cost in Ontario?
Most repairs in Ontario run between $160 and $4,700 depending on the job. A cap replacement sits at the low end, while a full liner installation is the high end. The biggest cost variables are flue height, roof access, and how much of the existing structure is salvageable. We quote a flat price before any work starts, so you’ll know the number before we touch the roof. Call (855) 382-6159 for a free estimate.

What pushes price up in Ontario is usually roof access and flue height. A two-story roofline or a steep pitch takes longer to set up safely, and a taller flue needs more liner or more brushing, which moves the number. We give you the flat price before any work starts, and that number doesn’t change after we get on the roof.
