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 Altadena, CA
Chimney repair in Altadena means working on homes built between 1910 and 1955, most with original clay-tile flues now 70 to 110 years old. Those flues crack under the Santa Ana heat-and-cool cycles that define foothill weather, and many have never been relined for modern use. Ontario Chimney has served Altadena since 2014. We’re the company homeowners call when a camera inspection shows spalling clay tiles, a rusted-out damper, or a crown that’s no longer shedding water. Call us at (833) 467-7685 when you need a straight answer about whether your fireplace is safe to burn.
Why Altadena Homes Are Different
Altadena’s chimney stock is dominated by the original masonry fireplaces of its 1910s through 1930s Arts-and-Crafts and Spanish Revival bungalows. Many were built when the foothill canyons were still lined with deodar cedar and oak groves, and that era left a specific legacy: unlined or clay-tile-lined flues that were never designed for continuous modern use. The clay tiles crack. The mortar joints erode. Fifty years of heat cycling plus the dry, hot Santa Ana winds of autumn create exactly the conditions that turn a hairline flue crack into a fire hazard. Add in the acorn woodpeckers and chimney swifts that nest in these older flues, and a standard sweep often turns into a repair call once we put a camera up there.
The county’s no-burn and abatement rules after canyon fires add another layer. When hillside vegetation burns, the smoke and ash settle into chimney caps and screens, and that debris restricts draft. We see a lot of Altadena callouts that start as “the fireplace is smoking” and end with a screen full of ash and pine needles. Knowing which canyons burned, and when, changes how we triage those calls. This is not generic chimney work. It’s foothill chimney work.

Our Main Altadena Services
Two services carry most of the calls we get from Altadena homeowners: chimney sweeping and dryer vent cleaning. Both are fire-safety maintenance, and both behave differently in this city’s housing stock than they do down in the flatlands.
Chimney Sweep in Altadena
A chimney sweep in Altadena is not a quick brush-and-go on a modern prefab unit. Most homes here have masonry fireplaces with clay-tile flues that need hands-on condition assessment, not just creosote removal. Our camera inspection is part of every sweep, because an older flue can look clean from the top and still have cracked tiles behind the surface. We also remove what foothill chimneys collect: acorn woodpecker nests, chimney swift colonies, and layered ash from wildfire season. Full details on what a sweep includes, what it costs, and how we handle older chimneys are on our Chimney Sweep in Altadena page.

Dryer Vent Cleaning in Altadena
Altadena’s ranch houses and bungalows often have long dryer vent runs through crawl spaces or across enclosed patios, and those runs collect lint faster than shorter direct vents. The NFPA identifies dryer vents as a leading cause of house fires, and a vent that’s never been cleaned in a 1940s or 1950s home is a real hazard. We treat dryer vent cleaning as its own service, not a tack-on to a sweep. Our technicians inspect the full run, report blockages, and document the before and after. For the full breakdown, visit Dryer Vent Cleaning in Altadena.

Chimney Repair in Altadena

Chimney repair in Altadena almost always comes back to the age of the flue. Homes built between 1910 and 1955 were constructed with clay-tile liners, and those tiles crack under decades of heat cycling. The Santa Ana winds accelerate the problem: hot, dry air pulls moisture out of brick and mortar, causing spalling and crown fractures. When a fireplace smokes or a chimney leaks, the cause is rarely one isolated issue. It’s usually a flue tile that’s shifted, a crown that’s let water in, and flashing that’s pulled away from the roofline. We start every repair with a camera inspection before recommending anything. If you want to understand the full scope of what we repair and how we price it, see our Chimney Repair hub.
Chimney Cap Installation
Signs you need it
Water in the firebox after rain, animal noise from the flue, or visible rust on an existing cap all point to a missing or failed chimney cap.
What it costs in Altadena
A new chimney cap installation in Altadena typically runs $400 to $700 depending on flue size and roofing access.
How we do it
We measure the flue outlet, select a Famco or Copperfield cap rated for the fireplace or appliance, secure it to the crown with mechanical fasteners, and seal the attachment points against water entry.
Chimney Liner Installation
Signs you need it
Cracked or missing clay flue tiles visible during inspection, persistent smoky fires, or a fireplace that cannot pass a level II inspection for a sale or insurance requirement.
What it costs in Altadena
Chimney liner installation in Altadena typically runs $2,500 to $6,000 depending on flue length, liner material, and whether the flue is straight or offset.
How we do it
We run a camera through the existing flue, size a DuraFlex stainless liner to the appliance, and pull it through the chimney from the top, insulating and connecting it at the appliance collar.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the chimney, damp drywall in the attic, or visible gaps between the roof and chimney masonry.
What it costs in Altadena
Chimney flashing repair in Altadena typically runs $600 to $1,500 depending on the number of chimney sides and roofline complexity.
How we do it
We remove the old flashing, inspect the roof decking for rot, install new step and counter flashing cut to fit the masonry, and seal the termination with a professional-grade sealant.
Chimney Crown Repair
Signs you need it
Cracks across the crown surface, standing water after rain, or spalling brick on the top courses of the chimney.
What it costs in Altadena
Chimney crown repair in Altadena typically runs $600 to $1,400 depending on crown size and whether we need to rebuild or just resurface.
How we do it
We chip away the damaged crown material, build a new concrete crown with proper overhang and wash slope, and trowel a crown sealer over the finished surface.

Yes. A camera inspection with a written report gives you documentation for the buyer or their inspector. We tell you what’s safe, what can wait, and what needs repair before closing.
