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 two things: a prefab metal flue from the 1960s or 70s that’s finally rusted through, or a damper and firebox that need replacement after decades of idle summers and Santa Ana wind-driven dust. We’re Chimney Sweep Chino, and we’ve served Ontario since 2011 with a focus on the factory-built systems that dominate this city’s postwar tract housing. Call (866) 321-6641 when you need a straight answer about whether your flue is safe to burn.
Why Ontario Homes Are Different
Ontario sits in the Inland Empire’s hot, smoggy basin where fireplaces are used rarely and lightly. That changes what we find. Most chimney work here is not heavy creosote removal. It’s inspection, sweep-and-certify for real estate transactions, and clearing the wind-blown dust, grit, and pest debris that accumulate in flues left idle for years. Because so many Ontario homes were built as postwar tract housing without masonry chimneys, the trade skews toward prefab metal firebox-and-flue systems and manufactured inserts rather than traditional brick stacks.
The housing stock tells the story. Ontario’s core is mid-century tract and ranch housing from the 1940s through 1970s, much of it built with factory-built chimneys. Add newer infill in the 91761 and 91762 corridor, and you get a mix of aging prefab flues, rusted dampers, and inserts retrofitted into original fireboxes. The hot, dry Santa Ana conditions mean flues sit idle for months collecting dust, leaves, and bird nests. Those dry winds drive debris and downdrafts back down uncapped chimneys. A technician working Ontario’s older tract streets learns to check for birds, squirrels, and wind-packed debris in idle, uncapped flues far more often than for creosote. And those same idle flues are what get flagged in pre-sale inspections.

Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: a chimney that needs cleaning and certification before a sale, or a dryer vent that’s gone too long without attention. Both are fire-safety work, and both are handled by the same crew.
Chimney Sweep in Ontario
An Ontario chimney sweep is often less about creosote and more about clearing what the wind left behind. We remove dust, leaves, nesting material, and the fine grit that blows in during Santa Ana events. We also inspect the flue, damper, and cap, then document everything for your records. If you’re selling a home in Ontario, the inspection report matters. Chimney Sweep in Ontario covers the full sweep-and-certify process, including what gets checked on prefab versus masonry systems.

Dryer Vent Cleaning in Ontario
Lint buildup is a leading cause of residential fires, and Ontario’s dry, windy climate doesn’t help. A vent that’s packed with lint makes your dryer run hotter and longer, and a dryer taking two cycles to dry a load is usually the first sign. We treat dryer vent cleaning as safety-critical work, not an upsell. Dryer Vent Cleaning in Ontario explains what we find in Ontario homes and why annual cleaning matters here.

Chimney Repair in Ontario
Chimney repair in Ontario often comes down to the age of the prefab metal flue. Homes built in the 1950s and 60s frequently have factory-built chimneys that were never designed to last 60 years. When the inner liner rusts through or the damper seizes, the repair is usually a liner installation or a cap and crown job rather than a masonry rebuild. The idle seasons don’t help: a flue that sits unused for months in dry heat and wind collects debris, and that debris holds moisture against the metal. Chimney Repair is our core service, and in Ontario it’s mostly about restoring prefab systems to safe working condition.
Chimney Cap Installation
Signs you need it
You hear birds or squirrels in the flue, or you see leaves and debris falling into the firebox.
What it costs in Ontario
Chimney cap installation in Ontario typically runs $190 – $390 depending on the cap size and flue configuration.
How we do it
We measure the flue, select a stainless or copper cap sized for the termination, and secure it to the crown with mechanical fasteners and a weatherproof seal.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, missing, or so warped that rain and embers get past it.
What it costs in Ontario
Replacement caps run $190 – $390 in Ontario, plus a bit more if the old cap’s fasteners have damaged the crown and need patching.
How we do it
We remove the old cap, clean the termination, inspect the flue opening, and install a correctly sized replacement from our stocked supply lines.
Chimney Liner Installation
Signs you need it
The flue shows rust-through, flaking metal, or gaps at the seams on a camera inspection, or the home inspector flagged the liner before a sale.
What it costs in Ontario
Chimney liner installation in Ontario ranges $1,500 – $3,400 depending on flue height, diameter, and whether it’s a flexible stainless or rigid system.
How we do it
We run a camera inspection first, then size and install a DuraFlex stainless liner, connect it to the appliance or insert, and re-crown the termination if needed.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the chimney, or visible gaps and lifted flashing at the roofline.
What it costs in Ontario
Flashing repair in Ontario typically runs $300 – $650 depending on how much of the flashing needs replacement.
How we do it
We remove the old flashing, install new step and counter flashing, and seal the joints with a high-temperature roofing sealant.
Chimney Crown Repair
Signs you need it
The concrete crown is cracked, spalling, or has gaps where the flue meets the crown, letting water into the chimney structure.
What it costs in Ontario
Crown repair in Ontario runs $300 – $700 depending on the extent of the cracking and whether we need to rebuild or just resurface.
How we do it
We clean and prep the crown, fill cracks with a flexible sealant, and resurface with a proper crown coat that sheds water away from the flue.

| Chimney cap installation | $190 – $390 |
| Chimney cap replacement | $190 – $390 |
| Chimney liner installation | $1,500 – $3,400 |
| Chimney flashing repair | $300 – $650 |

Do I need a new liner, or can the old one be repaired?
If the liner has rust holes or separated seams, patching is not safe. We recommend a full liner replacement because a compromised flue can leak heat and combustion gases into the home. A camera inspection shows you exactly what we see before any work is approved. Call (866) 321-6641 for a free estimate.
How long does a chimney repair job take in Ontario?
Most cap and crown jobs are done in a single visit. Liner installations take a half day to a full day depending on flue height and access. We schedule repairs around your availability and give you a firm price before work starts. Call (866) 321-6641 to schedule.
Brands We Service in Ontario
We specify products by name because materials matter. Our Ontario jobs use DuraFlex stainless liners, Olympia Chimney caps and terminations, Famco dampers, and Copperfield supply lines for repair and replacement work. Most common parts are stocked in our Chino shop, so a typical cap or damper job in Ontario doesn’t wait on a backorder. Our brands page lists the full product lines we work with.
