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 Sherman Oaks, CA
Chimney repair in Sherman Oaks usually means one of three things: a cracked crown from decades of Valley sun, a clay tile liner that’s spalled after sixty years of heat cycling, or flashing that’s separated from the roofline after minor seismic settling. Ontario Chimney handles all of it, from camera inspection to structural repair, so you’re not juggling a sweep company and a mason. Call (833) 467-7685 and we’ll tell you what we found, show you the evidence, and give you options.
Why Sherman Oaks Homes Are Different
Sherman Oaks sits in the San Fernando Valley basin, where wintertime temperature inversions trap smoke and particulate matter against the foothills. South Coast AQMD’s no-burn days hit Sherman Oaks hard because so many homes here were built with wood-burning fireplaces that are still in regular use. The result is a chimney culture where creosote accumulates faster than in coastal neighborhoods, and where homeowners often need education about burn-ban compliance as much as they need a sweep.
The hillside tracts south of Ventura Boulevard have some of the highest concentrations of original postwar masonry fireplaces in the Valley. These are 1940s-to-1960s ranch homes and tract builds with brick-and-mortar fireplaces and clay flue tiles now 50 to 70 years old. On hillside lots, chimney stacks are taller and more complex, subject to steeper pitch and the cumulative effects of earthquake-era masonry. When we inspect a Sherman Oaks chimney, we’re usually looking at decades of thermal stress, not a single season of neglect.
Styles & brands we work with
Our Main Sherman Oaks Services
Most Sherman Oaks homeowners call us for one of two reasons: a chimney that hasn’t been swept in years, or a dryer vent that’s never been cleaned. Both are fire-safety issues, and both get the same camera-verified, evidence-based treatment.
Chimney Sweep in Sherman Oaks
A sweep in Sherman Oaks often starts with a conversation about no-burn days and what the homeowner can legally burn. Santa Ana winds push debris into caps and spark arrestors from September through November, and creosote that hardened during the idle summer months is more difficult to remove than the soft, flaky residue you’d find after a single season. We inspect first, sweep second, and show you the before-and-after photos. For the full scope of sweep work in Sherman Oaks, see our dedicated Chimney Sweep in Sherman Oaks page.
Dryer Vent Cleaning in Sherman Oaks
Dryer vent cleaning is a core service here, not an add-on. Sherman Oaks laundry rooms are often interior closets with long vent runs through walls and out the roof, which means lint accumulates faster and is harder to reach. The NFPA identifies dryer vents as a leading cause of house fires, and those long Valley vent runs make this a maintenance item, not a nice-to-have. For details on how we clean vents in Sherman Oaks, visit our Dryer Vent Cleaning in Sherman Oaks page.

Chimney Repair in Sherman Oaks
Sherman Oaks homes from the 1940s through the 1960s still have their original clay flue tiles, and those tiles are now cracking, spalling, and separating under decades of heat and minor seismic activity. Add San Fernando Valley summers where fireplaces sit unused and untreated, and you get a repair category that’s as much about deferred maintenance as it is about sudden damage. Our Chimney Repair work starts with a camera inspection because the real problem is often invisible from the ground.
Chimney Cap Installation
Signs you need it
Water stains near the firebox, rust on the damper, or debris falling into the firebox usually mean your existing cap is missing, damaged, or not keeping rain and pests out.
What it costs in Sherman Oaks
Cap installation in Sherman Oaks typically runs $180 to $440 depending on the cap size, material, and whether we need to fabricate a custom fit for an odd flue dimension.
How we do it
We measure the flue, select a professional-grade cap (Famco or Gelco components), fasten it with mechanical hardware rather than adhesive, and verify the fit with the camera before we leave.
Chimney Liner Installation
Signs you need it
If your camera inspection shows cracked clay tiles, gaps between tile sections, or missing mortar joints, your flue liner is no longer containing combustion gases, and that’s a fire and carbon monoxide risk.
What it costs in Sherman Oaks
Liner installation in Sherman Oaks runs $1,200 to $4,000 depending on flue length, diameter, and whether we’re relining a masonry chimney or installing a full stainless system.
How we do it
We run a DuraFlex flexible liner system down the existing flue, connect it to the appliance collar, insulate where required, and seal the top with a proper cap and crown setup.
Chimney Flashing Repair
Signs you need it
Water staining on ceilings near the chimney chase or efflorescence on the chimney’s interior wall usually indicates flashing that’s separated from the roofline, common after Sherman Oaks’ minor seismic events.
What it costs in Sherman Oaks
Flashing repair in Sherman Oaks typically runs $250 to $700 depending on how much flashing is compromised and whether we need to work on a steep hillside roof.
How we do it
We remove the old flashing, inspect the roof deck and chimney chase for water damage, install new step and counter flashing with proper overlap, and seal every seam with a roofing-grade sealant that can handle Valley heat.
Chimney Crown Repair
Signs you need it
A cracked or crumbling crown lets water into the masonry itself, causing spalling brick and flue tile damage that spreads silently, especially after a wet Valley winter.
What it costs in Sherman Oaks
Crown repair in Sherman Oaks runs $300 to $900 depending on crown size and whether we’re doing a full recast or a surface repair with a bonding agent.
How we do it
We remove the damaged crown material, build a form that overhangs the chimney edge with a drip lip, pour a proper concrete crown, and seal it so water sheds away from the flue.
What Chimney Repair Costs in Sherman Oaks
| Item | Typical range in Sherman Oaks |
|---|---|
| Chimney cap installation | $180 – $440 |
| Chimney flashing repair | $250 – $700 |
| Chimney crown repair | $300 – $900 |
Sherman Oaks prices run slightly higher than flatland Valley neighborhoods because hillside access and steeper roofs add labor time, and because so many homes need custom fabrication for oddly sized postwar flues. We quote upfront, and the price we give you before we start is the price you pay.
How much does chimney repair cost in Sherman Oaks?
Your total depends on what the camera finds. A simple cap replacement starts around $180, while a full liner install with crown work can reach $4,000 on a complex hillside home. We give you a written estimate before any work begins.
Can you repair my chimney the same day you inspect it?
Simple repairs like cap replacement or flashing sealing can often be done same-day. Larger work like liner installation or a full crown recast requires a follow-up visit. We’ll schedule it while we’re on site.
Brands We Service in Sherman Oaks
We work with materials from Copperfield and Olympia Chimney, the two largest professional chimney supply distributors in the trade, plus DuraFlex stainless liners, HeatShield ceramic resurfacing, and Famco components for caps and dampers. Professional-grade materials, not hardware-store substitutes. Common parts are stocked locally, so most Sherman Oaks repairs start immediately. See our brands for the full list.
