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 usually means fixing heat-cracked caps, worn flashing, or a pre-fab unit that has baked under decades of inland sun. Most Ontario homes were built between the 1950s and 1990s, and their chimneys carry more wind damage and age-related wear than heavy creosote. We handle the repair, the inspection, and the cleanup in one call. If your flue system looks questionable, call (833) 805-3229 and we’ll tell you what’s actually going on.
Why Ontario Homes Are Different
Ontario sits on the edge of the Santa Ana wind corridor, which means one thing for chimneys: wind-driven debris. After a strong wind event, we pull bird nests, eucalyptus bark, and fine dust out of flues across the 91762 and 91764 ZIP codes. The older mid-century homes near downtown Ontario often have masonry fireplaces with original clay liners and caps that are 60-plus years old. Out east in the newer 91758 subdivisions, most fireplaces are pre-fab metal units from the 1980s or 1990s, often converted to gas logs. Those conversions matter. A gas log setup still vents through the same flue, and if the cap or crown is cracked, embers and exhaust have a clear escape path into the roof assembly. Intense summer heat bakes crowns until hairline cracks open up, and wind does the rest. This isn’t a heavy soot market like colder, wetter climates. Ontario jobs are more often about age, wind, and neglected caps than creosote buildup. We adjust the inspection to match: checking for crown cracks, cap rust, flue tile spalling, and debris blockages before we ever discuss a cleaning.
Styles & brands we work with





Our Main Ontario Services
Two services keep most Ontario homeowners calling us: chimney sweeping and dryer vent cleaning. Here’s what each involves in this city.
Chimney Sweep in Ontario
A sweep in Ontario is rarely about shoveling out soot. Most calls are gas-log checkups, cap inspections, and debris removal after Santa Ana events. We brush what needs brushing, run a camera through the flue, and document any damage we find. The dry Inland Empire climate means chimneys here age differently than coastal homes, and our inspection follows that pattern. If you haven’t had the flue looked at since converting to gas logs, start with a sweep and inspection. Learn more at Chimney Sweep in Ontario.

Dryer Vent Cleaning in Ontario
Dryer fires start in the vent, not the drum. Ontario’s dry, dusty air pushes lint into dryer vents faster than people expect, and a blocked vent forces your dryer to run hotter and longer. We treat dryer vent cleaning as a fire-safety service because that’s what it is. The vent is part of your home’s ventilation system, same as a chimney. For details specific to Ontario, see Dryer Vent Cleaning in Ontario.

Chimney Repair in Ontario
Chimney repair in Ontario comes down to two things: weather and age. The Santa Ana winds push debris into caps and crowns until they crack, and the summer sun bakes whatever is left. Many of the masonry chimneys on 1950s-era Ontario homes still have their original terra cotta liners, and once those spall or crack, exhaust gases begin leaking into places they shouldn’t. Our repair work covers everything from a simple cap replacement to a full liner install, and we use professional materials from Copperfield and Olympia Chimney, not whatever a hardware store happens to stock. If your inspection report came back with red flags, we can fix them. That’s the difference between a sweep-only company and a full-service Chimney Repair team. Here’s what most Ontario homeowners need.
Chimney Cap Installation
Signs you need it
You hear birds or critters in the flue, or water drips into the firebox after rain.
What it costs in Ontario
Chimney cap installations in Ontario typically run $400 to $850 depending on the cap type and the flue size.
How we do it
We measure the flue opening, set the correct cap and screen assembly, and secure it to the existing crown or flue tile.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, warped, or the mesh screen has gaps big enough for birds to get through.
What it costs in Ontario
Replacement caps in Ontario generally cost $350 to $700, including removal of the old unit and disposal.
How we do it
We remove the damaged cap, check the flue tile underneath for cracking, and install a new cap sized to the opening.
Chimney Liner Installation
Signs you need it
An inspection shows cracked flue tiles, gaps between tile joints, or missing mortar that lets exhaust into the chimney chase.
What it costs in Ontario
Liner installations in Ontario range from $2,000 to $6,500 depending on liner type, flue height, and access difficulty.
How we do it
We size the liner to the flue, run it from the firebox to the top, and connect it to the cap and crown with a sealed termination.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling near the fireplace or actual drips around the chimney during winter rain.
What it costs in Ontario
Flashing repair in Ontario typically runs $350 to $800, depending on how much of the existing flashing can be reused.
How we do it
We lift the shingles at the chimney base, cut back damaged flashing, replace or re-seal the joints, and test with a water check.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Chimney cap installation | $400 – $850 |
| Chimney cap replacement | $350 – $700 |
| Chimney liner installation | $2,000 – $6,500 |
| Chimney flashing repair | $350 – $800 |
Do I need a new liner if my chimney was converted to gas logs?
Not always. Gas logs produce less exhaust than wood, but the flue still needs to be intact and correctly sized. We only recommend a liner when camera inspection shows cracking, gaps, or spalling.
Can a cracked crown really cause that much damage?
Yes. Crown cracks let water into the masonry core, and when that water expands and contracts through Ontario’s hot days and cool nights, the structure deteriorates from inside. A $500 crown repair beats a $5,000 rebuild every time.
Brands We Service in Ontario
We stock and install products from DuraFlex, Olympia Chimney, and Famco. That matters because these are trade-grade materials built for actual chimney and ventilation work, not retail substitutes. Most common repair parts are on the truck when we arrive, which keeps the job faster. For a closer look at the product lines we work with, see our brands.

What pushes a price up in Ontario? Access is the big one. A two-story chimney on a 1980s tract home with a steep roof costs more to reach than a single-story mid-century ranch. The second factor is the condition of what’s underneath: if a cap replacement reveals a cracked crown or spalled flue tiles, the job scope changes. That’s why we quote flat prices before starting work. The price we give you is the price you pay, and if we find something else, you see the camera footage before we recommend anything.
Neighborhoods We Serve in Ontario
We work across Ontario, from the mid-century homes near downtown to the newer subdivisions on the east and south sides. Each area has slightly different housing stock, and that shapes what we find. Generally, older areas need more crown and flashing work, while newer pre-fab units need more cap and gas-log service. Response time for the Ontario area is typically within a week, and faster outside the fall rush.

FAQs About Chimney Company in Ontario
Most Ontario appointments are scheduled within five to seven business days. During the late summer and early fall, before the cooler weather hits, the schedule fills up faster, so call a few weeks ahead if you want a fall appointment.
Most basic repairs like cap replacement, flashing work, and crown sealing don’t require a permit. Full liner installations and structural masonry rebuilds can, depending on scope and the building department’s requirements. We’ll tell you when a permit is needed and how to handle it.
Yes. Much of our Ontario work is on pre-fab metal fireplaces from the 1980s and 1990s, many converted to gas logs. We inspect, clean, and repair those units, and we know which caps and components fit the common models installed in Inland Empire subdivisions.

What Ontario Customers Say
"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
— Yolanda Martinez"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Paige Norris"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
— Ryan Sullivan
