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 missing cap after a Santa Ana wind event, or a cracked clay flue tile in a 1960s tract home that hasn’t been inspected in decades. We’re Santa Ana Chimney Sweep, and we’ve served Ontario since 2016. Most of the chimneys we work on here sit idle for most of the year, so the real problems are wind damage, UV-baked mortar crowns, dust-packed flues, and pest nests, not heavy creosote buildup. Call us at (855) 341-9658 when you need a repair rather than just a cleaning.
Why Ontario Homes Are Different
Ontario’s chimney work is dominated by the Inland Empire’s hot, dry, wind-scoured climate rather than by heavy wood-burning. Fireplaces here mostly sit idle, so the real job is clearing out years of desert dust, tumbleweed debris, soot and pest nests, plus dry-rot and cracked masonry from intense UV and summer heat before the Santa Ana wind season. It’s a defensible-chimney and dust-debris market, not a creosote-heavy cold-climate one.
The housing stock tells the same story. Ontario is largely mid-century to late-20th-century tract housing across ZIP codes 91762 and 91764, with 1950s-70s single-story stucco homes plus newer 1980s-2000s subdivisions, many with masonry fireplaces and older clay flue tile that cracks with age and heat cycling. In the older tracts off the 91762/91764 core, chimney caps go missing in Santa Ana wind events and dry summer heat cracks mortar crowns. We routinely find birds’ nests and years of windblown dust packed in flues of fireplaces that haven’t seen a fire in seasons. That changes what we look for and how we repair it.
Styles & brands we work with





Our Main Ontario Services
Ontario homeowners call us most about two things: getting a chimney swept and inspected after years of disuse, and clearing dryer vents that have accumulated lint in homes where the dryer runs constantly through long, hot summers. Both are combustion-vent safety work.
Chimney Sweep in Ontario
A sweep in Ontario often means removing dust, debris, and nesting material more than creosote. We sweep the flue, check the cap and crown, and flag any cracks in the clay tile liner so small problems don’t become rebuilds. The dry climate means dust settles everywhere, and a fireplace that hasn’t been used in years can still be blocked. See our full Chimney Sweep in Ontario page for pricing and what to expect.

Dryer Vent Cleaning in Ontario
Dryer vents in Ontario fill with fine dust and lint faster than homeowners expect, especially in homes where the dryer shares a wall with the garage or runs daily. A clogged vent makes the dryer work harder and increases fire risk. We clean the full run from dryer to exterior termination. Details are on our Dryer Vent Cleaning in Ontario page.

Chimney Repair in Ontario
Chimney repair in Ontario comes down to two recurring problems we see across the 1950s-70s tracts and newer subdivisions: cracked clay flue tiles and damaged caps or crowns. The hot, arid summers bake mortar until it crumbles, and Santa Ana winds rip caps off or send debris down open flues. When we inspect a chimney in Ontario, we’re looking for UV-damaged mortar joints, missing spark arrestors, and hairline cracks in the clay liner that widen with every heat cycle. Repairing these issues early is always less expensive than a full rebuild. For a complete look at our repair scope, see Chimney Repair.
Chimney Cap Installation
Signs you need it
You hear birds or animals in the flue, find nesting material or debris at the fireplace base, or see water stains on the ceiling near the chimney chase.
What it costs in Ontario
A basic galvanized cap install around Ontario typically runs $260 to $480, with stainless steel caps adding $100 to $200 more depending on flue size.
How we do it
We measure the flue opening, source the correct cap from Olympia Chimney or Famco, secure it to the crown, and verify the mesh and hood are seated against wind uplift.
Chimney Crown Repair
Signs you need it
The concrete crown over your chimney has visible cracks, spalling, or missing chunks, and water is getting behind the brick face.
What it costs in Ontario
Crown repair in Ontario typically falls between $150 and $500, depending on whether we’re sealing hairline cracks or rebuilding the crown from scratch.
How we do it
We remove loose concrete, build a slight slope so water drains away from the flue, apply an acrylic bond coat, and set the new crown with an expansion gap around the tile.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Chimney cap replacement | $260 – $480 |
| Crown repair (seal or rebuild) | $150 – $500 |
| Flashing repair | $300 – $1,500 |
Prices move up when a chimney is tall or steep, when access requires a longer ladder setup, or when the crown is badly deteriorated and needs full reconstruction. We give you a flat price before we start so there’s no surprise at the end of the job.
Do I need a new liner, or can my chimney be repaired?
Most clay tile liners in Ontario can be repaired without a full replacement. HeatShield resurfacing seals hairline cracks and restores the flue surface without tearing out the chimney. Call (855) 341-9658 for an exact assessment.
How do I know if my chimney crown is failing?
Look for hairline cracks running across the concrete surface, pieces of mortar or concrete on the roof, or water in the firebox after rain. These are all signs we see regularly in Ontario’s older tracts. Estimates are free.

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."
— Scott Meyer"New to Santa Ana and had no idea who to call. A neighbor gave me their number and I've since passed it on to two other people on the street."
— Luis Guzman"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."
— Dev Rao
