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 one of three things: a cracked clay flue tile in a 1960s tract house, a rusted spark arrestor from Santa Ana wind grit, or a crown that has spent too many summers baking in 100-degree heat. Limestone Chimney Sweep handles all of it, and we carry the materials to fix what we find, not just hand over a report. Ontario’s housing stock is overwhelmingly mid-century stucco ranch homes with original masonry fireplaces, and many of those chimneys have sat unused for years before someone fires them up during a cold snap. That pattern creates heavy creosote loads, pest intrusion, and flue damage a coastal chimney company rarely sees. If your fireplace smokes, smells, or has not been inspected in years, call us at (855) 341-5439.
Why Ontario Homes Are Different
Ontario’s chimney problems follow a predictable rhythm, and it is tied directly to the city’s postwar building boom. The single-story stucco ranches built through the 1950s, 60s, and 70s across the 91762 and 91761 ZIP codes were almost all constructed with masonry fireplaces and clay tile flue liners. Those liners are now 50 to 70 years old. Clay tiles crack under repeated heating and cooling cycles, and once a tile shifts or splits, the gap exposes the surrounding masonry to heat and creosote. We find cracked flue tiles in Ontario more often than in almost any other Inland Empire city we work.
The climate compounds it. Ontario gets hot, dry summers where a fireplace sits completely idle for eight months. Then December and January nights drop into the 30s and 40s, and suddenly a chimney that has been dormant since spring is asked to move smoke and heat every night. Eucalyptus, palm, and pine debris blow into caps and screens during Santa Ana wind events, and animals build nests in flues that are not capped or screened properly. A very common Ontario call comes in March or April: the fireplace smoked all winter, the homeowner assumes creosote buildup, and we open the cap to find a spark arrestor packed solid with wind-driven grit and needle debris. It is a ventilation problem, not a sweeping problem, but it presents the same way.

Our Main Ontario Services
Most Ontario homeowners reach out for one of two reasons: a chimney that has not been cleaned in years, or a dryer vent that an inspector or appliance tech flagged. Both are fire-safety visits.
Chimney Sweep in Ontario
An Ontario chimney sweep is not the same job as a sweep in a coastal city. Here, we are dealing with fireplaces that sat unused for a decade, then ran hard through a cold winter. That produces a dense, glazed creosote that a basic brush pass will not remove, and it means we often spend as much time diagnosing airflow and cap blockage as we do sweeping the flue itself. If your Ontario home has a wood-burning fireplace that has not been cleaned in three or more years, start with a full inspection. Chimney Sweep in Ontario covers what to expect, what it costs, and how we handle heavy creosote in older tract homes.
Dryer Vent Cleaning in Ontario
Dryer vent cleaning is the other half of household fire-safety ventilation, and Ontario’s dry air makes lint buildup especially combustible. A clogged dryer vent is the leading cause of appliance fires in the United States, and in Ontario’s older homes, many vents are original to the house: long runs, tight bends, and screens that have never been cleaned. We treat this as a safety visit, not a chore. Each appointment includes a full pull of the dryer, a brush and vacuum pass through the full vent run, and a screen and termination check. Dryer Vent Cleaning in Ontario explains the process and typical pricing for local homes.

Chimney Repair in Ontario
Chimney repair in Ontario is less about dramatic failures and more about slow, weather-driven degradation. The original clay tile liners in 1950s and 60s ranch homes crack under decades of thermal cycling, and once they crack, the flue is no longer safely containing heat and combustion gases. The dry Santa Ana season accelerates crown and mortar damage, because wind-driven grit sands away the surface, then winter moisture gets into the hairline cracks. When we repair a chimney here, we are usually correcting problems that started years ago and were never caught because the chimney went uninspected. If you have not had your flue looked at in years, Chimney Repair from Limestone Chimney Sweep covers everything from caps to full liner rehabilitation.
Chimney Cap Installation
Signs you need it
Birds, squirrels, or roof rats nesting in the flue, water staining on the firebox walls, or a persistent musty smell coming from the fireplace are all signs your Ontario chimney is open to the elements.
What it costs in Ontario
Chimney cap installation in Ontario typically runs between $250 and $550 depending on flue size and access, with the cap itself accounting for roughly half that figure.
How we do it
We measure the flue dimensions, match the cap to the existing crown profile, mechanically fasten it rather than relying on friction fit, and verify the spark arrestor mesh is Santa Ana-wind rated.
Chimney Cap Replacement
Signs you need it
Rust perforation on the cap body, a spark arrestor screen that has blown loose, or visible daylight through the mesh means the cap has reached the end of its service life.
What it costs in Ontario
Replacing an existing cap in Ontario usually runs $220 to $480 installed, though custom sizes or oversized flues can push the material cost higher.
How we do it
We pull the old cap, inspect the crown and flue lip for hidden damage, install a new Famco or Copperfield cap sized to the flue, and secure it so Santa Ana gusts cannot lift it.
Chimney Liner Installation
Signs you need it
Cracked clay tiles visible during a camera inspection, deteriorating mortar joints between flue sections, or a fireplace that smokes into adjacent rooms signal that the liner is no longer safely containing exhaust.
What it costs in Ontario
Chimney liner installation in Ontario typically lands between $2,800 and $5,200 for a standard single-flue ranch home, with the liner material and insulation accounting for most of that range.
How we do it
We run a camera inspection first to document the existing flue, then size and install a DuraFlex stainless liner with proper insulation, and finish by verifying draft with the appliance actually running.
Chimney Flashing Repair
Signs you need it
Water staining on ceilings near the fireplace, peeling paint on the chimney chase, or visible gaps where the chimney meets the roof line mean the flashing has failed.
What it costs in Ontario
Chimney flashing repair in Ontario generally costs $380 to $800 depending on whether we are resealing the existing flashing or cutting out and replacing a section.
How we do it
We remove the failed sealant or flashing section, inspect the roof deck underneath for rot, install new step flashing and counterflashing, and seal it with a high-temperature, weather-grade sealant.
Chimney Crown Repair
Signs you need it
A spalled or crumbling crown surface, standing water pooling on the crown after rain, or cracks wider than a dime across the crown mean water is getting into the masonry.
What it costs in Ontario
Crown repair in Ontario typically runs $340 to $900, with full crown rebuilds on larger chimneys landing at the higher end of that range.
How we do it
We grind out the cracked surface, rebuild the crown with the proper overhang and drip edge, and seal it so water sheds away from the flue instead of soaking into the brickwork.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Chimney cap installation | $250 – $550 |
| Chimney cap replacement | $220 – $480 |
| Chimney liner installation | $2,800 – $5,200 |
| Chimney flashing repair | $380 – $800 |
| Chimney crown repair | $340 – $900 |
What pushes a repair higher in Ontario is usually access. A two-story chimney on a steep roof pitch is harder to work, and it adds labor. A single-story ranch with a walkable roof keeps things at the lower end. We quote a fixed price before any work starts, and nothing is recommended unless you can see the damage with your own eyes.
Do I need a camera inspection before a liner or repair quote?
Yes. A camera inspection is the only way to see inside the flue and know exactly what needs work, and we do not quote liner work without one. It documents cracked tiles, gaps, and blockages in a way no visual check can.
Can a cracked clay flue tile be patched, or does it need a liner?
Patching a cracked tile is not a reliable repair. Heat cycles will open the crack again, and the patch creates a restriction inside the flue. A stainless liner or a HeatShield restoration is the only way to create a continuous, sealed flue surface that will hold up.
Brands We Service in Ontario
We stock and install parts from Famco, Copperfield, Gelco, and Olympia Chimney in our Ontario service vehicles, which means caps, dampers, and ventilation components are warrantied and matched to the existing masonry, not whatever the hardware store had on the shelf. Our brands page shows the full line.

Service Area – Cities Near Ontario
Our work from Ontario regularly takes us into the neighboring Inland Empire cities with the same mid-century housing stock and Santa Ana wind exposure. We serve homeowners in Montclair, CA, Chino, CA, Los Serranos, CA, and Jurupa Valley, CA. Each has its own mix of tract ranches, newer builds, and chimney-age profiles, but the underlying issues are the same: old flue tiles, wind-driven debris, and fireplaces that sat idle too long.

FAQs About Chimney Company in Ontario
Most Ontario appointments are scheduled within three to five business days. During the fall, before the cold-snap season starts, we are busiest and lead times stretch. Call (855) 341-5439 to check current availability, and we will fit you in where the route allows.
Most standard chimney repairs, cap replacements, and liner installations do not require a separate city permit in Ontario. If the work involves structural masonry or a rebuild, the scope usually triggers a permit requirement, and we will tell you before anything is scheduled.
We handle both. The sweep, the inspection, the repair, and the material supply all come from one company, which means you never wait for a second contractor to show up before a fix moves forward. What we find during a sweep, we can usually repair on the same visit or schedule immediately after with a fixed price.

What Ontario Customers Say
"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
— Rachel Rhodes"Liner was cracked in two places. He walked me through the repair options honestly, including the one that was cheaper for him and better for me."
— Kurt Sutton"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."
