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 Commerce, CA
Chimney repair in Commerce usually means restoring older masonry flues and gas-appliance vents in homes built between the 1940s and 1960s, not sweeping romantic wood fires. Most of the chimneys we see here vent gas furnaces, wall heaters, and water heaters, and many original brick fireplaces have been capped or bricked over for decades. That changes the work: we spend more time on leak sealing, crown repair, vent inspections, and carbon monoxide safety than anywhere else in our service area. If you have a chimney or vent that needs a professional look, call Ontario Chimney at (833) 467-7685. We have served Commerce since 2014.
Why Commerce Homes Are Different
Commerce sits flat on the LA basin floor, just above sea level, surrounded by freeways and industrial corridors. The housing stock is largely small stucco single-story homes from the post-war tract buildout, with original brick fireplaces and interior masonry flues. Winters are mild, so there is no frost heave cracking crowns the way you see in colder climates. What we do see constantly is deferred maintenance on rental properties and a lot of chimneys that were sealed off years ago when owners switched to wall furnaces or gas inserts. Those abandoned flues still leak rainwater into the attic and can downdraft carbon monoxide into tight, weatherized homes. The basin’s winter inversions trap CO and smoke near ground level, which makes vent tightness a year-round safety concern in Commerce, not a cold-weather one. A technician walking any block of 1950s tract homes here will find the same pattern repeating: original brick fireplace, capped decades ago, with a flue that has never been inspected.

Our Main Commerce Services
Commerce homeowners call us most about two things: chimney sweeping for the fireplaces still in use and dryer vent cleaning for fire safety in older laundries. Both are handled by the same trained technicians.
Chimney Sweep in Commerce
For the homes that still use their original brick fireplaces, a proper sweep removes creosote, soot, and debris before it becomes a fire hazard inside the flue. In Commerce, we also check gas log sets and gas inserts that sit inside older masonry chimneys, since those are the more common heat source here. A sweep includes a visual check of the flue, smoke chamber, damper, and cap, and we photograph what we find so you can see it. Full details are on our Chimney Sweep in Commerce page.
Dryer Vent Cleaning in Commerce
Dryer vents are a leading cause of house fires, and cleaning them is maintenance, not optional. In Commerce’s older single-story homes, dryer ducts often run long horizontal distances through attics or crawlspaces, collecting lint at bends and joints. Our dryer vent cleaning is a standalone fire-safety service, not a throwaway add-on, and we document the before and after with photos. That is covered fully on the Dryer Vent Cleaning in Commerce page.
Chimney Repair in Commerce
Chimney repair in Commerce is dominated by two patterns: water damage from decades of exposed crowns and flashings, and venting failures in gas flues that were never designed for modern high-efficiency appliances. The mid-century masonry here is nearly all original, and in a city built this tightly, a cracked crown or rusted flashing is not cosmetic: water gets into the flue, erodes mortar joints, and shortens the life of the whole chimney. We are the Chimney Repair company that handles the full scope, from sweep to structural repair, so you work with one company from inspection through completion.
Chimney Cap Installation
Signs you need it
Rainwater or bird nesting material inside the flue, or a visible gap where the old cap used to sit.
What it costs in Commerce
Chimney cap installation in Commerce typically runs $285 to $685 depending on flue size and access.
How we do it
We measure the flue opening, fit a Galvanized or Copperfield cap to the existing crown, and mechanically fasten it so it stays put through basin wind and rain.
Chimney Crown Repair
Signs you need it
Cracked, spalled, or missing concrete on the top surface of the chimney, often with water staining on ceilings below.
What it costs in Commerce
Crown repair in Commerce ranges from $395 to $1,425 depending on crown size, crack depth, and whether we seal or rebuild.
How we do it
We chip out deteriorated material, form and pour a new crown with a slight slope to shed water, and add a flexible sealant so it can move with LA basin temperature swings.
What Chimney Repair Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Chimney cap installation | $285 – $685 |
| Chimney crown repair | $395 – $1,425 |
| Chimney flashing repair | $495 – $1,200 |
Do I really need a new liner if my chimney is only used for a gas furnace?
Sometimes no, but often yes. Older clay tile liners crack under years of heat cycling, and gas furnace exhaust is acidic enough to eat at mortar joints. We camera-inspect before recommending anything, and we will show you the footage. Call (833) 467-7685 for a straight answer.
How often should a chimney be swept in Commerce?
For gas appliance venting, an annual inspection is the right cadence, with sweeping as needed based on what we find. Wood-burning fireplaces should be swept after every 40 to 50 fires. Call (833) 467-7685 to schedule a check.
Brands We Service in Commerce
We install and service DuraFlex stainless steel liner systems, Famco caps and dampers, and we stock Copperfield components locally for faster turnaround on Commerce jobs. You can see the full list on our brands page. If a repair calls for a part, we keep the common ones on the truck and can usually handle it in one visit.

What pushes a Commerce job higher is usually access: a two-story roof line on a zero-lot-line tract home, a flue that runs through a tough attic chase, or masonry that needs rebuilding rather than patching. You will get a flat price before we start, and we will not recommend work you do not need.
