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 San Antonio Heights, CA
Chimney repair in San Antonio Heights usually means one of two things: a cracked clay flue from decades of heating-season use, or a chimney cap and spark arrestor that no longer meet the county’s wildland-urban interface rules. Homes here sit at 1,500 to 2,000 feet in the chaparral above the San Gabriel Valley, where Santa Ana winds turn a stray ember into a hillside fire faster than anywhere on the valley floor. Ontario Chimney has served San Antonio Heights since 2014, and we handle the full repair scope from a cracked crown to a complete DuraFlex reline. Call (833) 467-7685 for a free estimate.
Why San Antonio Heights Homes Are Different
The housing stock above the 210 freeway separates into two groups, and each one creates its own set of chimney problems. Mid-century ranch homes and custom hillside houses from the 1950s through the 1980s were built with masonry fireplaces and clay tile flues. Those original flues are now 40 to 70 years old. Repeated heating cycles from cold foothill winters cause hairline cracks that widen over time, and a cracked flue sends heat and combustion gases into the chimney chase instead of up and out.
The second group is older cabins, some still fitted with the original “Muslin” style clay flues. These liners are fragile enough that an aggressive sweep can crack them, so they need a slower, lower-torque approach. Add the chaparral that surrounds nearly every street here and the fire-safety stakes get higher. A chimney that would be a routine repair down in Upland becomes a defensible-space issue at this elevation. The county expects spark arrestors on any chimney serving a solid-fuel fireplace, and we verify that on every job. Many homes also sit at the end of long private driveways off narrow, unmarked roads that standard GPS doesn’t handle well, so our technicians plan routes before dispatch rather than relying on a phone screen.
Styles & brands we work with





Our Main San Antonio Heights Services
Repair work usually starts with one of the two services below. Both matter in San Antonio Heights for different reasons: one protects the flue itself, the other protects the whole house from a vent fire.
Chimney Sweep in San Antonio Heights
A chimney sweep here is part fire-safety check, part preventive inspection. We remove creosote buildup from November-through-March fireplace use, but we also verify the spark arrestor and cap are in place and intact, which matters more in the wildland-urban interface than almost anywhere else in the Inland Empire. Older clay tile flues in San Antonio Heights cabins get swept with a gentler method to avoid cracking the liner. Once we’re done, we’ll tell you what we found, show you the photos, and let you know if anything needs repair now or can wait. See the full scope on our Chimney Sweep in San Antonio Heights page.

Dryer Vent Cleaning in San Antonio Heights
Dryer vents clog with lint over time regardless of where you live, but in San Antonio Heights the nearest fire hydrant might be a quarter mile down a private road. The CPSC has documented dryer-vent fires as a persistent cause of house fires, and a clogged vent makes your dryer run hotter and longer. We clean the full vent run from the dryer connection to the exterior termination, clear blockages from bird or rodent nesting, and verify airflow at the cap. It’s a standalone service here, not a throwaway add-on. Details are on our Dryer Vent Cleaning in San Antonio Heights page.

Chimney Repair in San Antonio Heights

Chimney repair in San Antonio Heights spans everything from replacing a rusted rain cap to jackhammering out a failed clay flue and installing a new stainless steel liner. The homes here, built between the 1950s and 1980s, are now at the age where chimney crowns, flashings, and liners all start to fail around the same time. Cold foothill winters put the system through severe thermal cycling, and a cracked clay tile flue is not something to let ride, especially with wildfire season stretching longer each year. Ontario Chimney carries the full repair scope, which means you deal with one company from inspection through completion instead of coordinating a sweep service, a mason, and a liner installer. Our full service overview lives on the Chimney Repair page.
Chimney Cap Installation
Signs you need it
You have no cap, or the existing cap has rusted through, bent, or lost its spark arrestor screen.
What it costs in San Antonio Heights
Chimney cap installation in San Antonio Heights typically runs $200 – $600 depending on the flue size and cap type.
How we do it
We measure the flue opening, match a Gelco or Famco cap to the tile or pipe, secure it with mechanical fasteners, and verify the spark arrestor mesh meets county WUI screening requirements.
Chimney Cap Replacement
Signs you need it
The old cap is rusted through, missing sections of mesh, or the wind has torn it loose from the flue.
What it costs in San Antonio Heights
Replacing a damaged cap runs $250 – $700 in San Antonio Heights when a new mounting base or flue adapter is needed.
How we do it
We remove the failed cap, clean the flue lip, install the replacement with a proper mechanical connection, and test the spark arrestor screen before we leave.
Chimney Liner Installation
Signs you need it
You have a cracked clay tile flue, missing mortar joints between tiles, or your chimney is drafting poorly and a camera inspection shows flue gas leakage.
What it costs in San Antonio Heights
Liner installation in San Antonio Heights runs $2,500 – $5,500 depending on flue height, offset, and whether the old clay tiles need breakout.
How we do it
We run a camera inspection, remove or prep the old flue, pull a DuraFlex stainless liner through the chase, connect it to the appliance or fireplace, and pour an insulated seal to lock it in.
Chimney Flashing Repair
Signs you need it
You have water staining on the ceiling near the chimney, damp drywall in the firebox area, or visible gaps and rust at the roof line.
What it costs in San Antonio Heights
Flashing repair runs $350 – $900 depending on how much of the existing flashing can be salvaged and the roof pitch.
How we do it
We remove the failed flashing, install new step and counter flashing sealed to the chimney and roof deck, and test the repair with a hose before leaving.
Chimney Crown Repair
Signs you need it
The concrete crown on top of the chimney is cracked, spalling, or pooling water, or you can see exposed brick shoulders below the crown line.
What it costs in San Antonio Heights
Crown repair or recast runs $400 – $1,200 in San Antonio Heights depending on flue count, crown size, and whether a full removal is needed.
How we do it
We form and pour a new reinforced crown with an overhang and drip edge that sheds water away from the chimney, or we resurface a sound-but-cracked crown with a waterproof bonding compound.

| Chimney cap installation | $200 – $600 |
| Chimney cap replacement | $250 – $700 |
| Chimney liner installation | $2,500 – $5,500 |
| Chimney flashing repair | $350 – $900 |

Do I need to replace my clay tile liner if only one tile is cracked?
Not always. We run a camera inspection and show you the footage. If the crack is isolated and the rest of the flue is sound, sometimes a HeatShield ceramic resurfacing handles it at a lower cost than a full tear-out. You only replace when the inspection shows the cracks compromise the flue’s ability to contain heat. Call (833) 467-7685 and we’ll show you exactly what we see.
Can you repair the crown without rebuilding the whole chimney?
Yes, in most cases. We remove loose material, build forms, and pour a new reinforced crown with a proper drip edge. If the brick shoulders below the crown are still solid, the repair is isolated to the top few inches. We’ll tell you plainly if the masonry below needs more work.
Brands We Service in San Antonio Heights
We work with Copperfield and Olympia Chimney components for caps, dampers, and chase covers, and we install DuraFlex stainless steel liners on every reline job that requires a flexible system. We stock common cap sizes and flashing materials for San Antonio Heights homes, so most replacements don’t need a second trip. See our brands for the full list of what we stock and service.

Steep roofs, double-wall pipe, or a long private driveway don’t change the labor rate, but a multi-story flue and extensive masonry damage will push a liner job toward the top of that range. You get a flat price before we start, and the price we quote is the price you pay unless we find something structural that changes the scope, which we’ll show you before doing anything.

FAQs About Chimney Company in San Antonio Heights
We typically reach San Antonio Heights within one to three business days. Chimney and vent work here often runs in clusters, so residents on the same side of the 210 sometimes share a dispatch day, which helps with tight schedules. Call (833) 467-7685 and we’ll find the earliest available slot.
Most liner replacements are inside the existing flue and don’t require a permit. If we find structural masonry damage that means rebuilding part of the chimney, that may trigger county review since the area is unincorporated and wildland-urban interface rules apply. We’ll tell you before any work starts if a permit is needed and handle the paperwork.
Yes. We do pre-purchase chimney inspections for buyers and sellers throughout 91784. We camera-scan the flue, check the crown and flashing, and verify the spark arrestor and cap. You get a written report and photos same day, which most escrow timelines can easily accommodate. Call (833) 467-7685 to book the inspection, and we’ll work directly with your agent on scheduling.
