Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Sherman Oaks
A chimney sweep in Sherman Oaks typically costs $189 – $329, and most jobs are completed in under two hours. The real question in this part of the San Fernando Valley is rarely whether the flue needs brushing. It’s whether anyone has looked inside the stack since the last remodel, gas conversion, or decade of disuse. We’re Ashford Chimney Sweep, and we’ve been working on Sherman Oaks chimneys since 2012, from the older tracts near Ventura Boulevard to the hillside streets off Mulholland. Call (833) 589-9860 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Sherman Oaks Homeowners Call Ashford Chimney Sweep for Chimney Sweep
Most Sherman Oaks chimneys were built decades before anyone thought about gas logs, high-efficiency appliances, or the 1972 Clean Air Act. That changes the job. A sweep here is often less about creosote and more about figuring out what a prior owner left behind: an uncapped flue, a rusted damper, a smoke chamber glazed from years of misuse, or an appliance vented into a clay tile flue that was never sized for it. Homeowners on our chimney sweep route tell us the same thing: they want someone who can clean the stack and actually repair what the camera finds, without handing the job to another contractor.
That’s the difference our Sherman Oaks customers come back for. We don’t end the visit with an inspection report and a referral list. When we find a cracked crown, a seized damper, or a spalling clay tile, we can fix it in the same visit using the same professional-grade parts we stock in our vans: DuraFlex liner systems, HeatShield ceramic restorative, and Olympia Chimney components. We clean the flue, show you the camera footage, and if a repair is actually needed, we do the work ourselves. No mystery, no handoff, no upselling theater. Dennis Duran built the company around that standard, and it’s why homeowners from Van Nuys to Studio City keep our number saved.

Gas Fireplace Cleaning in Sherman Oaks
Gas Fireplace Cleaning in Sherman Oaks usually costs $149 – $249, and it’s one of the most common calls we take in the 91403 and 91423 ZIP codes. Many of the 1950s ranches here were converted from wood to gas logs decades ago, and the fireplaces were never properly recommissioned for gas. The logs look fine from the living room, but the flue above them may still be original clay tile, the damper may be rusted open, and the gas log set may be venting into a chamber that was never designed for it. We clean the firebox, inspect the log set and burner, verify the damper functions, and run a camera up the flue to confirm the venting is actually moving combustion gases out of the house.
What We Check in a Gas Conversion
On a gas-converted fireplace, we pay close attention to the damper position. A damper that was left fully open for wood burning should be adjusted for gas, so heat and exhaust don’t disappear up the stack. We also look for rust on the damper plate and any sign that the gas log set has been burning with incomplete combustion, which leaves a distinctive powdery residue.
Prefab Mediterranean-Style Units
Some newer Sherman Oaks homes have prefab metal fireplaces, and those require a different cleaning method from the original brick and clay tile stacks. We use brushes and vacuums designed for factory-built metal flues, and we never run a steel chimney brush down a prefab pipe, because it can tear the thin metal liner. If you’re not sure which type you have, tell us the year your home was built when you call.
Chimney Maintenance in Sherman Oaks
Chimney Maintenance in Sherman Oaks is a $149 – $189 annual service that catches the slow failures before they become expensive ones. The Valley’s dry summer heat cracks stucco-clad crowns and mortar joints, and the Santa Ana winds that come through in the fall pack leaves and debris into uncapped flues. A maintenance visit is a visual inspection, a flue brushing if creosote or soot is present, a crown and damper check, and a camera run if anything looks off. The goal is a stack that drafts correctly and doesn’t surprise you with smoke on the first cold night.
Crown and Damper Care
The crown is the concrete or mortar cap at the top of the chimney. In Sherman Oaks, where stucco chimneys bake in direct sun all summer, crown cracking is common. A cracked crown lets water into the masonry, and once water gets in, the mortar joints start to spall. We check the crown, seal small cracks when that’s all that’s needed, and tell you plainly when a crown rebuild is the right call rather than a patch that won’t hold.
Pre-Season Flue Check
Chimney swifts and other birds nest in uncapped Sherman Oaks flues, especially in the hillside streets off Mulholland. A pre-season check in October is a common call here, and it’s the cheapest way to avoid the moment when smoke backs up into the living room because a nest is sitting on the smoke shelf. We remove nests, install Gelco caps when needed, and show you the footage of what came out.
Trusted Brands We Service in Sherman Oaks
We stock and install DuraFlex flexible liner systems, the same professional-grade product that certified chimney contractors order through distributors like Copperfield and Olympia Chimney. That matters because big-box retail shelf liners and caps are not the same thing. A DuraFlex liner is code-listed for the job it does, and we can install one in a Sherman Oaks brick chimney without tearing apart the masonry. For flues that don’t need a full reline, we use HeatShield ceramic restorative to resurface and seal the existing clay tile. It’s a repair option most basic sweeps can’t offer, and it’s often a fraction of the cost of a full reline.
Common Chimney Sweep Problems We See in Sherman Oaks Homes
- Dormant gas-converted flues with sound tile. Many homes here haven’t burned wood since the 1980s, and their clay tile flues are still solid. We see upsellers recommend full relines on flues like these every year, even when the only real issue is a cracked crown or a rusted damper. We won’t recommend a reline unless the camera shows the tile actually failing.
- Cracked stucco crowns from Valley summer heat. The direct sun on Sherman Oaks rooftops bakes stucco crowns until the mortar cracks and water gets into the chimney structure. A brush-only sweep misses this, because the brush cleans the inside of the flue and never touches the crown at the top.
- Bird nests in uncapped hillside flues. The streets off Mulholland have older chimneys with no caps, and chimney swifts build in them all spring and summer. The first fall fire sends smoke pouring back into the house. We pull the nest, show you the smoke shelf on camera, and install a properly sized cap.
- Appliances vented into undersized clay tile. I’ve seen remodels along Ventura Boulevard where a furnace or water heater was rerouted into the original fireplace flue without resizing. The flue wasn’t built for that appliance’s exhaust, and it creates a drafting problem that no amount of brushing will fix. The camera run is how we identify it.

FAQs About Chimney Sweep in Sherman Oaks
Yes, and the reason is the gas conversion itself. Your chimney was built to move wood smoke up a clay tile flue, and the gas log set that replaced the wood burner produces exhaust at a different temperature and volume. If the damper was never adjusted correctly, or if the flue has been uncapped and collecting debris for thirty years, the system may not be venting properly. The inspection checks for rusted dampers, blocked flues, and cracked crowns, all of which happen on dormant chimneys. It does not mean the flue needs a reline, which is exactly what the camera will tell us before anyone tries to sell you one.
You’ll watch the camera footage with us, on the monitor, before any repair is recommended. We run a camera up the flue and show you exactly what’s there. If the clay tile is sound and only the crown needs sealing, that’s what we tell you and that’s all we recommend. HeatShield is a real product we use when the tile is genuinely failing, because it resurfaces the flue without a teardown. But the standard in this company, set by Dennis Duran, is that no one recommends a reline without camera evidence the homeowner can see for themselves. That rule is how we’ve kept Sherman Oaks customers since 2012.
The most common cause we see in the Mulholland hills is a bird nest or a heavy debris pack sitting on the smoke shelf. Chimney swifts nest in uncapped flues all spring, and the dry Santa Ana winds add leaves on top. When you light the first fire, the smoke hits that blockage and spills back into the room instead of rising. The fix is a sweep to remove the nest and debris, then a Gelco or Olympia Chimney cap to keep it from happening again. It’s a fast job, and it’s the reason October is our busiest month in Sherman Oaks.
Yes, and getting this wrong causes damage. A prefab fireplace has a thin metal flue, not clay tile or masonry. The brushes we use on a prefab are sized and designed for prefab pipe, and we never run a brick-chimney brush up a metal flue because it can tear the liner. We also check the firebox panels and the termination cap at the roofline, since prefab terminations in Sherman Oaks sun and wind tend to fail earlier than the masonry stacks.
Creosote comes in three stages. First-stage is a flaky, dusty residue that a standard chimney brush removes cleanly. Second-stage is a sticky, tar-like glaze that builds up on clay tile after repeated slow, cool fires. Third-stage is hardened, shiny residue that a brush won’t remove, and that’s where a chemical treatment or mechanical removal is needed. In Sherman Oaks, where many homes don’t burn wood often, most creosote we see is first or early second stage. But gas-converted flues that were never cleaned after years of wood burning before the conversion can have hardened glaze hiding behind the log set. The brushwork depends on what the camera shows.
