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 starts with an inspection, because this city’s older homes hide problems that a basic sweep won’t catch. We’re seeing cracked crowns, missing caps, and original clay liners in 1950s fireplaces near Euclid Avenue that have never been touched. If your chimney hasn’t been opened up and looked at in years, call (855) 341-8132 and we’ll tell you exactly what’s happening inside.
Why Ontario Homes Are Different
Ontario’s housing stock matters more than most homeowners realize when it comes to chimney work. We work in post-WWII tract homes and mid-century ranches throughout 91762 and 91764 where the fireplaces are original to the house. That means clay flue tiles installed when Eisenhower was president, mortar joints that have been baking in Inland Empire summers for 60-plus years, and in plenty of cases, no chimney cap at all. The original builders often skipped caps to save money, and those chimneys have been catching rain, leaves, and birds for decades since.
The climate creates a second layer of risk. Ontario gets mild winters, so fireplaces sit dormant for months at a time, then fire up during cold snaps. Creosote builds during those bursts of use, and when Santa Ana winds push down through the passes, the downdraft can force smoke and embers back toward the flue walls. Homes in 91758 and 91798 near the foothills get this more than others. We’ve also found that many Ontario owners assume their chimney is fine because they don’t use it much, but sporadic use with no inspection means small problems become big ones quietly. A cracked crown leaks, water freezes and thaws in the masonry, and by the time smoke starts backing up, the liner is already compromised.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a chimney sweep they’ve been putting off, or a dryer vent that’s stopped moving air properly. Here’s what each one looks like in this city.
Chimney Sweep in Ontario
In Ontario’s older homes, a sweep isn’t just brushing out soot. We’re checking the condition of the flue, looking for the creosote that builds from sporadic use, and making sure a Santa Ana gust won’t push smoke back into the living room. Homes with original fireplaces and no cap are the ones where a routine sweep turns up debris, nests, or early liner damage. Our Chimney Sweep in Ontario page covers what to expect, including how long it takes and what we photograph for you during the job.
Dryer Vent Cleaning in Ontario
Ontario’s dry climate means a lot of lint, and a lot of homeowners who run laundry year-round and never think about the vent behind the machine. A clogged dryer vent is a serious fire hazard, and in older tract homes the vent runs are often longer than they should be, with bends that collect lint faster. We clean the full run and check for the kinks and gaps that make the problem worse. Details are on our Dryer Vent Cleaning in Ontario page, including signs that your vent needs attention this year.

Chimney Repair in Ontario
Most of the chimney repairs we handle in Ontario trace back to two things: the age of the original masonry, and years of deferred maintenance that seemed fine because the fireplace wasn’t used often. A 1950s brick chimney near Euclid Avenue with an original clay liner and no cap has been absorbing rain and debris for decades. When the liner cracks, or the crown breaks down, the damage accelerates fast. In Ontario’s dry heat, masonry stays rigid, and when the rains finally come, water moves into every hairline crack and makes it worse. The fix isn’t always a full rebuild. Many of these repairs come down to replacing a cap, repairing flashing, or resurfacing a damaged liner with HeatShield ceramic rather than tearing out the old one. Our full Chimney Repair hub explains the range of work we handle.
Chimney Cap Installation
Signs you need it
Your chimney has open flue tiles with no cover and you’ve had rain, birds, or debris get inside.
What it costs in Ontario
Chimney cap installation in Ontario typically runs from $250 to $600, depending on the flue size and the cap material.
How we do it
We measure the flue, confirm the correct cap size, place a manufacturer-grade Gelco cap over the flue, and secure it so it stays put through Ontario’s Santa Ana winds.
Chimney Cap Replacement
Signs you need it
Your existing cap is rusted through, bent, missing mesh, or no longer sealed against water.
What it costs in Ontario
Chimney cap replacement in Ontario usually runs from $300 to $650 when we’re pulling off an old cap and setting a new one.
How we do it
We remove the old cap, inspect the flue crown underneath, set a new cap sized for the flue, and seal the connection so water can’t find a path through.
Chimney Liner Installation
Signs you need it
Your flue tiles are cracked, missing, or sized wrong for the appliance, and your inspector or we have documented smoke or gas leakage.
What it costs in Ontario
Chimney liner installation in Ontario ranges from $1,800 to $4,500, depending on the length and the liner system required.
How we do it
We size the liner to the appliance, drop a professional-grade DuraFlex liner through the flue, connect it properly, and verify the draft before we finish.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling or walls near the chimney after rain, or the metal around the chimney base is pulling away.
What it costs in Ontario
Chimney flashing repair in Ontario typically costs from $400 to $900, depending on how much of the flashing needs replacing.
How we do it
We remove the damaged flashing, inspect the roofline joint, replace the flashing with proper step and counter flashing, and seal it against the masonry.
Chimney Crown Repair
Signs you need it
The concrete crown at the top of the chimney is cracked, spalling, or holding water, which is a frequent issue on Ontario’s older masonry chimneys.
What it costs in Ontario
Chimney crown repair in Ontario ranges from $600 to $1,500, depending on how much of the crown needs rebuilding.
How we do it
We chip out the damaged crown, build a proper form, and pour or set a new crown sloped to shed water away from the flue.

How much does chimney repair cost in Ontario?
Most chimney repairs in Ontario fall between $250 and $4,500 depending on the job. A basic cap install starts around $250, while a full liner replacement with professional-grade materials runs higher. We quote before work begins so there are no surprises.
Do I need a new liner, or can mine be repaired?
Not every cracked liner means a full replacement. In many Ontario homes we use HeatShield ceramic resurfacing to seal the damaged sections, which avoids a tear-out. We only recommend a new liner when the old one can’t be safely resurfaced, and we show you camera photos either way.
Brands We Service in Ontario
We specify trade-supply parts from brands like Gelco, Olympia Chimney, and Copperfield, which means the caps, liners, and components we install in Ontario homes aren’t off-the-shelf hardware store stock. We carry common sizes locally, which speeds up turnaround on most Ontario repair jobs. Our our brands page lists the full lineup.

What pushes repair prices up in Ontario is usually the age of the original structure. A 1950s chimney that’s never had a cap or crown repair tends to cost more than a newer home with a clean flue, because there’s more damage to address before the new part goes on. We give an upfront price before any work begins, so you know what the Ontario job costs before we start.

We schedule most Ontario appointments within a few days, and since we’re based in nearby Pomona, the drive is short. If you’ve got water coming in around the chimney or smoke backing up, call (855) 341-8132 and we’ll prioritize the inspection.
Most chimney repairs, including cap replacement, flashing, and liner resurfacing, don’t require a city permit in Ontario. Larger structural rebuilds sometimes do. We’ll tell you before work starts if your specific job requires any paperwork.
Even sporadic use builds creosote, and an unused chimney still takes on water and debris if it isn’t capped. We recommend at least an inspection every couple of years for Ontario homes, especially older ones with original masonry. Call (855) 341-8132 for an honest assessment and a free estimate.

What Ontario Customers Say
"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Adam Pruitt"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
— Elena Rodriguez"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."
