Chimney Company in Los Serranos, CA
Chimney repair in Los Serranos is different from a few miles down the hill in Chino or Ontario. The 1980s and 1990s tract and semi-custom homes here were largely built around prefab metal fireboxes and stucco-clad chases, not brick-and-mortar stacks. That means the work we do most often is on factory-built flue components, chase covers, spark arrestors, and the flashing where the chase meets the roofline. Ontario Chimney has served Los Serranos since 2014, and we approach every job by starting at the roofline, because that is where this neighborhood’s problems actually live. Call (833) 467-7685 when you need a straight answer about what your chimney needs.
Why Los Serranos Homes Are Different
Los Serranos sits in the foothills of the Chino Hills, elevated enough that the Santa Ana winds hit harder here than on the flat basin below. Those winds drive ember-laden debris, dry eucalyptus leaves, and seed pods into chimney caps and spark arrestors with real force. A chimney can look perfectly clean at the firebox while the cap and spark screen are packed solid after a single wind event. That is why inspections in Los Serranos have to start at the roofline, not the hearth.
The housing stock compounds this. Most homes in the 91709 ZIP were built between the 1980s and early 2000s, and a large share use prefabricated metal chimneys with stucco-covered wooden chase structures. The parts that actually fail here are chase covers that rust through, spark arrestors that clog with wind-blown debris, and flashing that pulls away from the stucco. It is less about crumbling mortar and more about factory-built components reaching the end of their service life. We stock the parts these systems need, and we know which failures are urgent and which can safely wait until spring.
Styles & brands we work with





Our Main Los Serranos Services
Most Los Serranos homeowners call us for one of two reasons: a chimney that needs cleaning and inspection, or a dryer vent that has become a fire hazard. Both are handled by the same trained technicians.
Chimney Sweep in Los Serranos
A sweep here is not just brushing the flue. Because of the Santa Ana winds, we check the cap and spark arrestor for packed eucalyptus leaves and seed pods before we even light a test fire. On ridgeline streets, clogged spark screens are the single most common cause of smoky fireplace calls. After the sweep, we photograph what we found so you can see it yourself. Chimney Sweep in Los Serranos is a full write-up of what the job includes and how we price it.

Dryer Vent Cleaning in Los Serranos
Dryer vent cleaning is a core fire-safety service for us, not an add-on. Lint builds up in the vent run, restricts airflow, and can ignite. The NFPA has identified dryer vents as a leading cause of house fires, and the dry inland summers in Los Serranos mean lint dries out fast and becomes a fuel source. Dryer Vent Cleaning in Los Serranos is its own dedicated page with the full breakdown of what we inspect and how often it needs doing.

Chimney Repair in Los Serranos

Chimney repair in Los Serranos usually comes down to components wearing out. The metal chase covers on 1980s and 1990s tract homes rust through after decades of hot, dry summers and occasional rain, and once rust perforates the cover, water gets into the chase and damages the flue inside. The Santa Ana winds accelerate the damage by wedging debris into caps and spark arrestors, which then trap moisture against the metal. The good news is that most of these repairs are direct, code-compliant, and do not require tearing apart the wall. We handle everything from dampers to flashing and full liner work, and our Chimney Repair hub page covers the full scope of what our technicians can handle.
Chimney Cap Installation
Signs you need it
You see water stains on the ceiling near the chimney chase, or you can see daylight through a rusted or missing cap from the ground.
What it costs in Los Serranos
Chimney cap installation in Los Serranos typically runs $200 to $650 depending on cap size, material, and roof access.
How we do it
We measure the flue opening, select a cap sized for the chase or liner, and secure it to the chase top with mechanical fasteners and a weather seal.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, the spark arrestor mesh is torn or blocked beyond cleaning, or the cap has blown off entirely during a Santa Ana event.
What it costs in Los Serranos
Chimney cap replacement in Los Serranos typically costs $250 to $700, with the higher end covering custom sizing for odd chase dimensions.
How we do it
We remove the old cap, inspect the chase top and flue outlet for hidden damage, then install a new cap with a secure mechanical fit and intact spark screen.
Chimney Crown Repair
Signs you need it
Hairline cracks in the crown, spalling concrete at the top of the chimney, or water pooling at the base of a stucco chase after rain.
What it costs in Los Serranos
Chimney crown repair in Los Serranos typically runs $300 to $800 depending on the extent of cracking and whether a full recoat is needed.
How we do it
We clean and prep the crown surface, fill cracks with a weather-resistant sealant, and apply a crown coat that sheds water instead of absorbing it.
What Chimney Repair Costs in Los Serranos
| Item | Typical range in Los Serranos |
|---|---|
| Chimney cap installation | $200 – $650 |
| Chimney cap replacement | $250 – $700 |
| Chimney crown repair | $300 – $800 |
How do I know if my chimney repair is urgent?
If you see water stains, rust, or hear debris dropping inside the chase during wind events, call us. A rusted-through chase cover lets water reach the flue and the surrounding framing, and that damage compounds quickly. We will tell you plainly what can wait and what cannot, with photos to back it up.
Do you have to tear out the stucco to fix a chimney in Los Serranos?
Usually not. Most repairs on prefab systems here are done at the chase top or through the firebox opening. The stucco is a chase covering, not the chimney itself, so we can often fix the cap, crown, and liner without removing any wall material.
Brands We Service in Los Serranos
We install and service components from Famco, Copperfield, and DuraFlex. These are the brands chimney professionals actually specify, and we keep common Los Serranos sizes in local stock, so cap and crown replacements do not wait on long lead times. See our brands for the full list and why we standardize on them.
