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 Downey, CA
Chimney repair in Downey usually comes down to one pattern we see constantly: a 1950s or 60s ranch home with an original clay-tile flue that has never been touched. The fireplace works, so nobody thinks about it until a winter cold snap hits and the family actually lights a fire. That’s when cracked flue tiles, missing caps, and years of hardened creosote surface. Ontario Chimney has served Downey since 2014, and we handle the full scope from inspection through structural repair, so you’re not juggling a sweep company and a mason. Call (833) 467-7685 for a free estimate.
Why Downey Homes Are Different
Downey’s housing stock is dominated by single-story stucco ranch homes and postwar tract houses built between the 1950s and 1970s. In the 90240 and 90241 ZIP codes especially, those homes still carry their original brick masonry fireplaces with clay-tile flues. Most were built before modern stainless liners and chimney caps were standard. That means a lot of Downey chimneys are running on 60-plus-year-old materials that were never designed for today’s gas appliances or the accumulated stress of Santa Ana wind cycles.
The bigger issue is Downey’s climate. Hot, dry summers and mild winters mean fireplaces sit idle for eight or nine months a year. During that stretch, creosote left over from the last fire hardens into a glaze that a basic brush will not remove. Birds and squirrels move into uncapped flues. By the time a cold snap or holiday fire rolls around, the chimney is blocked or the creosote is a fire risk. The safety gap is real: mild-weather neglect meets an aging stock of unlined masonry flues. In spring, we get a steady stream of calls about chimney swifts and squirrel nests in flues that were never capped.
Styles & brands we work with
Our Main Downey Services
Most Downey homeowners call us for one of two things: the routine chimney sweep they’ve been putting off, or the dryer vent cleaning that their lint trap situation has made urgent. Both are fire-safety services, and both run through the same trained team.
Chimney Sweep in Downey
A chimney sweep in Downey means more than brushing out ash. On these 1950s-era flues, we’re looking for cracked clay tiles, hidden blockages from nesting animals, and creosote levels that have built up over years of occasional use. Since many Downey chimneys go months between fires, the creosote has time to harden, which makes it harder to remove and more flammable if it ignites. We document everything with camera inspection so you can see the condition yourself. Learn more about Chimney Sweep in Downey.
Dryer Vent Cleaning in Downey
Dryer vents in Downey’s older ranch homes often run long horizontal distances from the laundry room to an exterior wall, sometimes 15 to 25 feet. Every foot of that run collects lint, and in Downey’s dry air that lint is as flammable as kindling. We clean the full run, check for proper termination, and verify airflow. It’s a standalone service with us, not an upsell. See the full scope on Dryer Vent Cleaning in Downey.

Chimney Repair in Downey
Chimney repair in Downey almost always starts with the same discovery: a clay flue liner that has cracked invisibly. Homes built in the 1950s and 60s used clay tiles that expand and contract at different rates than the surrounding masonry. After decades of Santa Ana heat and rare winter fires, those tiles split. The cracks let heat and combustion gases reach the brick and framing, and nobody knows until a sweep finds it. Our repair work ranges from caps and flashing to full relining and crown rebuilds. Ontario Chimney handles all of it, from camera-documented inspection to the final repair, so you deal with one company instead of coordinating a cleaner and a contractor. The full scope is covered under Chimney Repair.
Chimney Cap Installation
Signs you need it
You hear animals in the chimney, see water staining near the fireplace, or notice debris falling into the firebox.
What it costs in Downey
Chimney cap installation in Downey typically runs $250 to $450, depending on the flue size and cap material.
How we do it
We measure the flue, recommend a cap sized for Downey’s bird and squirrel pressure, and secure it to the crown with mechanical fasteners, not adhesive.
Chimney Liner Installation
Signs you need it
Your sweep finds cracked or missing clay tiles, or you’re switching to a modern gas appliance that requires a correctly sized liner.
What it costs in Downey
A DuraFlex stainless liner installation in Downey typically runs $2,200 to $4,800, depending on flue length and access.
How we do it
We run a camera inspection first, measure the flue precisely, then install a DuraFlex liner sized to the appliance and the home’s original masons.
Chimney Flashing Repair
Signs you need it
You see water staining on the ceiling near the chimney, or the flashing is visibly separated from the roof line.
What it costs in Downey
Flashing repair in Downey typically runs $400 to $850, depending on how much of the existing flashing is salvageable.
How we do it
We remove the old flashing, inspect the roof joint, and install new step and counter flashing that actually follows the roofline, then seal it with high-temp caulk.
Chimney Crown Repair
Signs you need it
The concrete crown on top of the chimney is cracked, spalling, or missing chunks, letting water into the masonry.
What it costs in Downey
Crown repair in Downey typically runs $500 to $950, depending on whether it needs patching or a full recast.
How we do it
We clean the existing crown, assess the damage, and either patch with a masonry sealant rated for exterior use or recast and taper the crown so water sheds properly.
What Chimney Repair Costs in Downey
| Item | Typical range in Downey |
|---|---|
| Chimney cap installation | $250 – $450 |
| Chimney flashing repair | $400 – $850 |
| Chimney crown repair | $500 – $950 |
Can you repair a chimney liner without tearing down the brick?
Yes. In most Downey homes, we install a DuraFlex stainless liner through the existing flue, so no masonry demolition is needed. For thinner-walled clay flues that are still structurally sound, HeatShield ceramic resurfacing is another option that restores the flue surface without a full tear-out.
Do I really need a new liner, or can it wait?
If the liner is cracked, it can’t wait once you’re using the fireplace or a gas appliance. The gaps let heat and gases reach combustible framing. Call us for a camera inspection, and we’ll show you exactly what we’re seeing before any work is recommended.
Brands We Service in Downey
We work with professional-grade materials only: DuraFlex for stainless liners, Famco caps and dampers, and Copperfield and HeatShield systems for repairs and resurfacing. Parts are stocked in our service vehicles, not ordered after the fact. For larger relining jobs, that means the work in Downey can start the same visit. See the full list on our brands.

In Downey, the biggest price drivers are access and flue length. A single-story ranch is easier to work on than a two-story addition, but a long flue run with offset sections pushes liner and sweep costs up. We give a upfront price before work begins, so what we quote is what you pay.

We cover all four Downey ZIP codes: 90239, 90240, 90241, and 90242. That includes the older tract-home pockets where chimneys still carry original clay liners, plus the newer construction where gas logs and direct-vent units are more common.

FAQs About Chimney Company in Downey
Most Downey inspections are scheduled within two to four business days. During the holiday fire-season rush in December and January, it can stretch to a week. We recommend booking your pre-season sweep in September or October, before the first cold snap hits.
For standard maintenance like sweeping, cap installation, and liner replacement, the city of Downey does not require a separate permit. Structural work like a full chimney rebuild may trigger permit requirements, but we handle that paperwork and let you know upfront if it applies to your job.
Yes. For landlords and property managers in Downey with multiple rental units or multi-flue chimneys, we can inspect all flues in one visit with a single service call charge. Each flue gets its own camera report, so you have documentation for each unit.
