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 comes down to two things: cracked clay tile liners in 1950s – 1970s tract homes, and wind-driven grit packed into flues along the 60 freeway corridor. We see it every fall when homeowners fire up fireplaces for the first time after months of 100°F heat. Chimney Sweep Jurupa Valley has served Ontario since 2015, and we handle the full repair scope most sweeps won’t touch: liner replacement, crown rebuilds, flashing, and cap work. Call (866) 285-4905 when you need someone who can actually fix what the inspection finds.
Why Ontario Homes Are Different
Ontario’s housing stock runs heavily to single-story tract homes built between the 1950s and 1970s. That matters because most of those original masonry fireplaces have clay tile liners, and clay tiles do not flex. The expansive soils in this part of the Inland Empire shift with moisture cycles, and over decades that movement transfers straight up through the chimney structure. Hairline cracks in flue tiles are common in ZIPs like 91761, 91762, and 91764, and those cracks are exactly where heat and creosote find their way into places they shouldn’t be.
Climate does its own damage here. Ontario sits in a semi-arid pocket where summers regularly push past 100°F and winter nights drop into the 30s. That temperature swing is brutal on masonry. The short, intense burn season means chimneys sit dormant for eight or nine months, then get asked to handle nightly fires for a few cold weeks. Add the Santa Ana winds pushing fine dust off the Cajon Pass and you get a distinctive problem: reddish windblown grit mixed with creosote inside uncapped flues, especially on the east side of town. Cleaning here often means removing more than just ash. It means clearing what the wind put there first.

Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a chimney that hasn’t been cleaned in years, or a dryer vent that’s slowly becoming a fire hazard. Both are maintenance items people tend to forget about until something smells wrong.
Chimney Sweep in Ontario
A proper sweep in Ontario starts with understanding what’s actually inside your flue. In older tract homes, that often means creosote buildup from years of burning whatever was cheap and available. In homes near the foothills, it’s often bird nests and windblown debris packed in during the dry months. We clean with professional-grade brushes and vacuums sized for your flue, then tell you what we found, with photos when something needs attention. If you’re due for a cleaning, start with the Chimney Sweep in Ontario page.

Dryer Vent Cleaning in Ontario
Dryer vents collect lint the same way chimneys collect creosote, and in Ontario’s dry climate that lint can become a fire hazard faster than people expect. Homes with long vent runs, especially in older single-story layouts where the dryer sits far from an exterior wall, are the worst offenders. We clean the full run, not just the first few feet behind the dryer, and we check for crushed or disconnected sections. If your dryer takes two cycles to dry a load, read the Dryer Vent Cleaning in Ontario page before you call.

Chimney Repair in Ontario
Chimney repair in Ontario is a different job than it is in coastal cities. The combination of expansive soil, extreme summer heat, and wind-driven grit means we’re not just patching mortar. We’re rebuilding crowns, replacing cracked clay liners with proper flex systems, and fixing flashing that the Santa Anas have worked loose over the years. When we inspect a chimney here, we’re looking for the specific failure patterns this housing stock is known for. That’s the difference between a repair that holds and one that fails again in two years. For a complete picture of our repair scope, see the Chimney Repair hub.
Chimney Cap Installation
Signs you need it
You see rust flakes on the hearth, smell a campfire odor when the fireplace isn’t in use, or hear birds inside the flue.
What it costs in Ontario
A new cap for an Ontario home typically runs $180 to $310 depending on the flue size and material.
How we do it
We measure the flue opening, set a stainless or copper cap that locks onto the tile with mechanical fasteners, not just caulk, and check that the mesh size won’t restrict draft.
Chimney Cap Replacement
Signs you need it
The existing cap has rusted through, the mesh is torn open, or a strong windstorm has shifted it off-center.
What it costs in Ontario
Replacement runs $200 to $340 in Ontario, more if the old cap was mortared in and the crown needs cleanup first.
How we do it
We remove the old cap, wire-brush the crown surface, and install a new cap sized correctly for the flue tile, then verify the spark arrestor mesh is secure.
Chimney Liner Installation
Signs you need it
An inspection shows cracked or spalled clay tile, or you see sand-like mortar debris accumulating at the bottom of your firebox.
What it costs in Ontario
Liner installation in Ontario usually falls between $3,400 and $6,400 for a full flex liner system including insulation where needed.
How we do it
We remove what’s left of the failed liner, size a proper flex system for the appliance and flue dimensions, insulate if the home requires it, and connect it to a properly sized connector at the appliance.
Chimney Flashing Repair
Signs you need it
Brown water stains on the ceiling near the chimney, wet insulation in the attic around the chase, or tar that’s cracked and pulling away from the masonry.
What it costs in Ontario
Flashing repair in Ontario ranges from $280 to $545 for typical repairs, more if the roof decking underneath has rotted.
How we do it
We cut back the old flashing, install step flashing and counter-flashing correctly layered into the mortar joints, and seal with a high-temperature masonry sealant rated for Inland Empire sun.
Chimney Crown Repair
Signs you need it
The concrete crown on top of your chimney has visible cracks, missing chunks, or water pooling on top after rain.
What it costs in Ontario
Crown repair runs $260 to $550 for a standard rebuild, depending on whether the old crown needs full removal.
How we do it
We chip out the deteriorated crown, form an overhang that sheds water past the brick faces, and pour new crown material that can handle Ontario’s temperature swings.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Chimney cap installation | $180 – $310 |
| Chimney cap replacement | $200 – $340 |
| Chimney liner installation | $3,400 – $6,400 |
| Chimney flashing repair | $280 – $545 |
| Chimney crown repair | $260 – $550 |
What pushes repair costs higher in Ontario is clay-tile flue damage that’s gone unnoticed through several burn seasons, and older single-story homes where chimney access from the roof requires more setup than a simple walk-up. Whatever the scope, the price is agreed before we start.
How long does a chimney liner last in Ontario?
A properly installed flex liner typically lasts 20 – 30 years in Ontario’s climate, though clay tile liners in 1950s – 1970s homes here often fail sooner due to soil movement and extreme temperature cycling. Annual inspections catch cracking early.
Do most Ontario chimneys need a liner replacement?
Not most, but a meaningful share do. Homes built before 1980 with original clay tile and years of hot fires are the highest-risk group. If an inspection shows spalled tile or missing mortar joints, a liner is the safest fix.
Brands We Service in Ontario
We stock and install parts from our brands including Olympia Chimney, Copperfield, and Gelco components. Because we source from trade supply networks, we’re not waiting on hardware-store substitutes when your Ontario repair needs a specific flue component or cap size. Most common parts are on the truck the day we arrive.

| Service | Typical range in Ontario |

| Chimney sweep (standard cleaning) | $160 – $260 |
| Chimney sweep with bird nest removal | $190 – $350 |

Ontario pricing tends to run toward the higher end of those ranges when homes have long-neglected flues, uncapped chimneys full of windblown grit, or original clay liners that need more than a basic sweep. No matter what we find, the price is set before the work starts, and nothing gets added without you seeing the evidence first.
Neighborhoods We Serve in Ontario
We work throughout Ontario, from the older neighborhoods near downtown where fireboxes run narrow and shallow, to the 1950s and 1960s tract home subdivisions spread across 91762 and 91764 where clay tile flues have been doing the same job for sixty-plus years. The east side near the 60 freeway and the foothills gets the worst of the Santa Ana dust load, so those homes tend to need more thorough cleanings and more frequent cap checks.
- Downtown Ontario (91762)
- North Ontario (91761, 91764)
- East Ontario near the 60 corridor (91761, 91762)
- Ontario Ranch area (91762, 91764)
- Creekside and West Ontario (91758, 91762)

What Ontario Customers Say
"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."
- Kevin Kim"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
- Veronica Vargas"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
- Amanda Sullivan
