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 dealing with a 50-year-old masonry fireplace that hasn’t been opened since last winter. San Bernardino Chimney Sweep handles that first call: we inspect the flue, the damper, the crown, and the cap, then tell you straight whether it needs a sweep, a repair, or nothing at all. Ontario’s dry, dusty summers and occasional Santa Ana winds mean flues collect fine soot and debris even when the fireplace sits idle. Call (877) 516-7159 when you’re ready to have it looked at.
Why Ontario Homes Are Different
Ontario is an Inland Empire city where a large share of homes were built in the postwar boom and now have original masonry fireplaces that see only occasional winter use but sit in dry, dusty, wind-prone air. The real work here is less about heavy creosote and more about clearing years of dust, soot, and occasional bird nests before the first cold snap, plus confirming the flue is sound after decades of little use.
Much of Ontario’s housing is mid-century tract construction from the 1950s through the 1970s. That means single-story stucco homes with fireplaces built the old way: clay flue tiles, cast-iron dampers, and masonry crowns that have baked under 50 summers of Inland Empire heat. Many of those damper assemblies are original to the house. Some are stuck open, some are stuck closed, and plenty have hairline cracks in the flue tiles that nobody has ever looked at.
In the older neighborhoods near downtown and along the Euclid Avenue corridor, it’s common to find original 1950s fireplaces with no chimney cap. Birds and squirrels nest in the flue during spring and summer. The first fall cleaning often turns up a nest, and the cap should always be recommended. A missing cap in Ontario also means winter rains and Santa Ana-driven debris get straight into the flue, which accelerates deterioration of those older clay liners.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us first about a fireplace that hasn’t been cleaned in years, or a dryer vent that hasn’t been cleared since the house was bought. Both are covered below.
Chimney Sweep in Ontario
An Ontario chimney sweep here starts with the reality that most flues are underused but full of dust, soot, and sometimes a nest from a spring bird. We inspect before we sweep, then run rotary and hand brushes sized to the flue, clearing the full path from firebox to cap. If the damper is stuck or the flue shows cracks, we’ll document it and explain what’s urgent and what can wait. Since San Bernardino Chimney Sweep is a repair company, not just a cleaning service, we can fix what the inspection finds. The full detail is on our Chimney Sweep in Ontario page.
Dryer Vent Cleaning in Ontario
Your dryer vent is a fire risk too. Lint builds up in the duct behind the dryer and along the run to the exterior, and in Ontario’s dry air that lint is tinder-dry. We disconnect the dryer, brush and vacuum the full duct run, and confirm proper airflow at the outside termination. Homes along the Euclid Avenue corridor often have long horizontal vent runs through the slab or attic that trap more lint than shorter side-wall vents. We cover this in detail on our Dryer Vent Cleaning in Ontario page.

Chimney Repair in Ontario
Chimney repair in Ontario is often a direct result of the housing era. Homes built in the 1950s and 1960s have fireplaces with original clay flue tiles that have been through decades of Inland Empire heat, occasional rain, and long dry spells. The most common call is for a crumbling crown, a missing cap, or a flue liner with spider-web cracks that leak heat and gas into the home. We inspect with a camera, show you what we see, and only recommend work the photos support. That’s the whole point of our Chimney Repair service: we find it and we fix it, and nothing gets recommended without evidence you can look at yourself.
Chimney Cap Installation
Signs you need it
The flue is open to the sky, you hear birds or scratching from the fireplace, or you’ve found twigs and nesting material behind the damper.
What it costs in Ontario
Chimney cap installation in Ontario generally runs $260 – $540, with the higher end for multi-flue or custom masonry crowns.
How we do it
We measure the flue, select a stainless cap sized to the existing tile or chase, secure it to the flue or crown, and verify the draw before we leave.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, the mesh is torn, or the cap has blown off entirely and left the flue exposed.
What it costs in Ontario
Replacing an existing cap here falls between $270 – $550, depending on flue size and whether we need a standard or custom-fit cap.
How we do it
We pull the old cap, check the exposed flue tile for damage, install the new cap to fit the current flue dimensions, and seal any gaps.
Chimney Liner Installation
Signs you need it
Camera inspection shows cracked or separated clay tiles, you smell smoke inside the home, or a repair path won’t bring the flue to safe condition.
What it costs in Ontario
A new chimney liner in Ontario typically runs $3,950 – $6,850, with the higher end for long or difficult runs common in older single-story tract homes.
How we do it
We size the liner to the flue, install it through the existing chimney, insulate where required, connect it to the appliance or fireplace, and document the full run.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the chimney, damp attic insulation around the stack, or visible gaps and pulled flashing at the roofline.
What it costs in Ontario
Flashing repair around an Ontario chimney is mostly $380 – $735, less if it’s a simple caulk-and-seal and more if the step flashing needs replacement.
How we do it
We strip the failed sealant, inspect the step and counter flashing, reset or replace what’s needed, and seal the transition with proper masonry-rated sealant.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Chimney cap installation | $260 – $540 |
| Chimney cap replacement | $270 – $550 |
| Chimney liner installation | $3,950 – $6,850 |
| Chimney flashing repair | $380 – $735 |
What pushes a repair higher in Ontario is access and age. A chimney on a single-story stucco home with an easy ladder path is one price; a steep roofline or a flue with deep tile damage is another. We quote a flat price before we start, after the inspection, so you know the number before any work is authorized.
Do I really need a new liner, or can it be resurfaced?
Many Ontario liners can be resurfaced with HeatShield instead of fully replaced. If the clay tiles are cracked but the structure is sound, HeatShield’s Cerfractory material seals and restores the flue surface for less than a new liner. We only recommend full replacement when resurfacing won’t restore safe clearances. Call (877) 516-7159 and we’ll camera the flue and show you.
Can you fix this the same day you find it?
For caps, flashing, and crown work, the answer is usually yes once we have the part on the truck. Liner work takes longer because the liner is often sized to the flue and ordered specifically for the home. We’ll tell you which one you’re looking at before you pay anything.
Brands We Service in Ontario
San Bernardino Chimney Sweep works with DuraFlex, HeatShield, and Copperfield components. We stock common cap sizes and repair materials, so most cap and crown work in Ontario isn’t waiting on a shipment. See our brands for the full lineup we install and the repair methods we use with them.

FAQs About Chimney Company in Ontario
Most Ontario calls are scheduled within 2 to 3 days. During the fall, when everyone is lighting the first fire of the season, our calendar fills further out, so calling in September or early October gets you ahead of the rush.
Most cap, crown, flashing, and liner resurfacing work does not require a permit because it’s repair, not structural replacement. For full liner installation or any masonry rebuilding, we’ll tell you if the scope crosses into permit territory before work starts.
Yes. Older homes near downtown have fireplaces with thicker masonry and narrower flues, and we size our brushes and inspection cameras to those dimensions. We’ve worked on enough 1920s and 1930s chimneys in Ontario to know what to expect when we open the damper.
