Worth knowing

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, CA most often comes down to two jobs: relining older single-wall metal flues in 1950s – 1970s tract homes, and repairing crowns and flashing that the Santa Ana winds and dry alluvial dust have worked loose over the years. Ontario straddles the wind corridor at the foot of the Cajon Pass, so our techs regularly find smoke backing up through cracked flues and downdraft-blown soot in fireboxes after a strong wind event. Prestige Chimney has served Ontario since 2017. Call (833) 407-0587 for a repair evaluation.

Why Ontario Homes Are Different

Ontario’s housing stock is overwhelmingly postwar tract and ranch-style, built between the 1950s and 1970s. Many of those original brick masonry fireplaces are still in service, paired with single-wall metal flues that were never designed to handle 50-plus years of hot, dry summers followed by cold Santa Ana winter evenings. The thermal swing matters here. Flue liners expand and contract through Ontario’s seasonal extremes, and after a long dormant summer, a first fire in November can crack a liner that looked fine in April.

The wind is the second factor. Ontario sits directly in the Santa Ana River wind corridor below the Cajon Pass. When those dry winds push down through the foothills, they carry fine alluvial dust and drive it back down chimneys, especially on north-facing slopes. We routinely see soot and ash blown into fireboxes and smoke backing up through flues after strong Santa Ana events, a downdraft pattern that does not show up in the calmer Inland Empire basins to the south. The 91758 and 91798 rural-edge parcels add older wood-burning stoves on larger lots into the mix, and those setups often have older metal flue systems that need inspection and retrofit before they are safe to burn again.

Our Main Ontario Services

The two calls Ontario homeowners make most often are for chimney sweeping before the burning season, and for dryer vent cleaning after noticing longer dry cycles or a burning smell. Both are covered by the same team.

Chimney Sweep in Ontario

An Ontario chimney sweep is creosote removal plus dust and debris extraction from a flue that has sat dormant through a hot, dry summer. Because this city sits in a wind corridor, our techs also check for downdraft-blown soot settling into the firebox and damper assembly. The sweep includes a full Level 1 inspection, and anything found during the sweep can move directly into repair, keeping your chimney safe before the first fire. Full details are on the Chimney Sweep in Ontario page.

Dryer Vent Cleaning in Ontario

Dryer vent cleaning in Ontario is about lint accumulation inside the vent run, which is the leading appliance-related fire cause cited by the U.S. Fire Administration. Ontario’s dry climate and hard water can make lint especially fine and prone to compacting in longer vent runs common to postwar floor plans. We clean the full vent length from dryer to exterior termination and check for crushed or disconnected sections. Full details are on the Dryer Vent Cleaning in Ontario page.

Chimney Repair in Ontario

Chimney repair in Ontario is heavily driven by the age of the housing stock and the local wind patterns. Homes built in the 1950s through 1970s across ZIPs 91762 and 91764 often have original clay tile liners or single-wall metal flues that have cracked from decades of thermal cycling between hot summers and cold Santa Ana winter nights. When a strong wind event pushes down through the Cajon Pass corridor, smoke backs up through those compromised liners and into the home. Prestige Chimney handles Chimney Repair as a primary service, and because we also sweep, a problem spotted during cleaning can be quoted and fixed in the same visit.

Chimney Liner Installation

Signs you need it

Smoke backing into the living room on windy nights, flaking clay shards in the firebox, or visible gaps in an older metal flue indicate the liner has failed and is no longer containing combustion gases.

What it costs in Ontario

Chimney liner installation in Ontario typically runs $150 to $250 per foot of flue, plus materials, depending on liner diameter and access from the roof.

How we do it

We camera-scan the flue to confirm condition, then size and drop a professional-grade liner, commonly DuraFlex or HeatShield-specified materials, and finish with a proper cap and crown seal off.

Chimney Crown Repair

Signs you need it

Cracks in the cement crown, water staining on the ceiling near the chimney, or spalling brick at the top mean water has been getting through the crown and into the masonry below.

What it costs in Ontario

Crown repair in Ontario typically runs $150 to $300, depending on whether we reseal surface cracks or build and reform the crown with fresh cement.

How we do it

We remove loose or deteriorated crown material, apply a proper expansion joint sealant, and resurface with fresh mortar or a prefabricated crown cap, so water sheds away from the flue.

Chimney Cap Installation

Signs you need it

Water entering the flue after rain, birds or rodents in the firebox, or downdraft smoke blowing into the room during Santa Ana events all point to a missing or undersized cap.

What it costs in Ontario

Chimney cap installation in Ontario typically runs $150 to $500, depending on cap material, flue size, and whether custom sizing is needed for older masonry flues.

How we do it

We measure the flue opening, install a stainless or copper cap sized to the flue with a proper draft hood, and secure it to the crown with mechanical fasteners.

Chimney Flashing Repair

Signs you need it

Water staining along the ceiling where the chimney meets the roofline, or curling and separated flashing metal, means the seal between chimney and roof has failed.

What it costs in Ontario

Flashing repair in Ontario typically runs $150 to $400, depending on whether we reseal existing flashing or cut and fit new step flashing and counter-flashing.

How we do it

We remove old sealant and damaged flashing, and install new step flashing with Copperfield or Famco materials where replacement is warranted, sealed and counter-flashed to shed water correctly.

Chimney liner installation (per foot) $150 – $250

How quickly can you repair a chimney in Ontario?

What Ontario Customers Say

★★★★★ 4.8 from 12+ reviews

"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."

— Dustin Parker

"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."

— Beatriz Hernandez

"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."

— Rafael Castillo
