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 North Hollywood
Chimney sweeping in North Hollywood typically costs $189 – $329, and because our crews are already working the San Fernando Valley every week, we can usually get to most 91601 and 91602 homes within a few business days. If you live in a 1920s – 1950s bungalow or Spanish Colonial in North Hollywood, your chimney is likely original masonry with decades of creosote, cracked mortar, and possibly post-Northridge structural damage you can’t see from the ground. Al Vickers and the Ontario Chimney crew know exactly what to look for on these older Valley stacks. Call (833) 467-7685 for a straight answer on what your chimney actually needs.
Why Ontario Chimney Is North Hollywood’s Preferred Chimney Sweep Company
North Hollywood homeowners call us because we work on old masonry chimneys every day, not as a side gig. Most of the chimneys we inspect in the NoHo Arts District and the bungalow blocks off Magnolia and Burbank Boulevard were built before modern seismic codes existed, which means a basic brush sweep isn’t enough. We document what we find with camera photos and show you the evidence before any repair is recommended. No pressure, no mystery pricing.
Our reputation in North Hollywood comes from telling homeowners the truth about their flues. That sometimes means saying “this can wait another season” or “your chimney is fine, but your neighbor’s venting is the problem.” That kind of honesty is rare in this trade, and it’s why property managers along the Red Line corridor keep our number for their rental units. When you call, you get Al’s team, not a rotating cast of subcontractors.
North Hollywood response time matters because the Valley fire season doesn’t wait. We stock common parts for older brick fireboxes and clay flue liners locally, so we’re not waiting on a warehouse in another county to start your repair. Call (833) 467-7685 and we’ll give you a real arrival window, not a four-hour spread.

Chimney Sweep Certified in North Hollywood
A Chimney Sweep Certified job in North Hollywood means more than running a brush up the flue: it’s a full inspection of the firebox, throat, damper, flue tiles, and crown, with written documentation of creosote levels and any masonry cracks or separated clay tile. Homeowners in North Hollywood’s older housing stock should get this level of service, not a quick brush-and-go, because a 1928 bungalow chimney has had 95 years to develop problems a basic sweep will never catch. A certified sweep in North Hollywood runs $189 – $329 depending on flue height and creosote condition.
Inspecting the Shared Stack
In North Hollywood duplexes and attached bungalows, one masonry stack often holds two or more flues. We check for cross-contamination between adjacent flues, where a neighbor’s gas appliance vent can push exhaust through a cracked liner into your firebox opening. That’s a real danger a basic one-flue sweep misses entirely.
Documentation and Photo Evidence
We photograph every creosote glaze, spalled brick, and hairline crack we find. You see exactly what we see, before anyone quotes a repair. For the post-1994 Northridge homes across 91601 and 91602, that photo file becomes your chimney’s medical record going forward.
Gas Fireplace Cleaning in North Hollywood
Gas fireplace cleaning in North Hollywood addresses a different set of problems than wood-burning sweeps: soot buildup on ceramic logs, mineral scale on glass doors, clogged burner ports, and venting blockages in the gas flue. Many mid-century stucco tract homes in North Hollywood converted from wood to gas decades ago, and those converted units rarely get the annual service they need. Gas fireplace cleaning in North Hollywood typically runs $149 – $249 depending on unit type and access.
Soot, Scale, and Venting
A gas fireplace that hasn’t been cleaned in a few seasons shows white mineral buildup on the glass and black soot film on the logs, signs the burn is running rich or the vent is restricted. We disassemble, clean, and inspect the entire log set and burner assembly in place.
The Gas Flue Check
Converted wood-burning chimneys venting gas appliances need a different inspection than open fireplaces, since gas exhaust is cooler and holds moisture longer. We check for condensation damage to clay tile and confirm the flue is correctly sized for the appliance, not just for the fireplace that used to be there.
Trusted Brands We Service in North Hollywood
When a North Hollywood chimney needs more than a sweep, we use the same materials certified chimney professionals specify. We install and service DuraFlex stainless steel liner systems, which handle the offset flues common in older Valley chimneys where rigid liners can’t navigate the angles. For flue damage, applicator-level familiarity with HeatShield ceramic resurfacing often repairs a deteriorated clay liner without a full tear-out. And we source components through Copperfield and Olympia Chimney, the two largest professional chimney supply distributors in the trade. That means the cap, damper, or liner we install in your North Hollywood home is the same part a CSIA contractor in Chicago would spec, not a big-box substitute.

AfterCommon Chimney Sweep Problems We See in North Hollywood Homes
- Shared-stack cross-contamination: In attached bungalows and duplexes across 91601, a neighbor’s gas water heater venting into an adjacent flue can push exhaust through a hairline crack into your chimney. A single-flue sweep never sees it.
- Hidden crown failure behind stucco: Many North Hollywood chimneys are wrapped in stucco, which hides a cracked concrete crown and spalling mortar. The exterior looks smooth; the interior tells a different story once we get on the roof.
- Post-Northridge hairline cracks at the roofline: The 1994 quake shifted thousands of Valley chimneys, and many 91601 and 91602 stacks now have separated flue tiles that still draft fine on a mild day. A Level 2 inspection is the only way to confirm they’re safe.
- Third-degree creosote glaze: Older fireboxes with restricted airflow produce a hard, shiny creosote glaze that a standard brush can’t remove. This is where chimney fires start, and we see it regularly in pre-1950s North Hollywood homes.

FAQs About Chimney Sweep in North Hollywood
Yes, and this is exactly what our Level 2 inspection covers. We camera both flues in the shared stack, confirm the wythe between them is intact, and look for cross-contamination where exhaust from one flue migrates into the other. On a bungalow block near the NoHo Arts District in 91601, we found a neighbor’s gas water heater vent tied into an adjacent flue of the same stack, with separated clay tiles letting exhaust move sideways through a hairline crack at the roofline. We documented it, flagged it, and set the owner up with a relining plan before anyone lit a fire. Call (833) 467-7685 to schedule a shared-stack inspection.
A basic brush sweep clears creosote from one flue and stops there. Your 1920s bungalow chimney in North Hollywood has original clay tile, single-wythe brick, no seismic bracing, and nearly a century of thermal cycling plus one major earthquake. A Level 2 inspection with a camera shows us what the brush can’t: hairline cracks at the roofline, separated flue tiles, and whether the crown is still doing its job. In a 95-year-old chimney, running a brush without a camera is guesswork. Call (833) 467-7685 and we’ll quote the Level 2 before we touch the roof.
Yes, and it does regularly across North Hollywood. Stucco cladding wraps the masonry stack and hides the concrete crown, the mortar joints, and any spalling brick behind a smooth facade. A cracked crown lets water into the masonry core, and in the Valley’s dry heat, that water expands and contracts the mortar until the crown fails further. The only way to know is to get on the roof and look, which we do on every sweep. Call (833) 467-7685 to have your stucco-clad chimney inspected.
Third-degree creosote is a hard, shiny, tar-like glaze that forms when flue temperatures are low and airflow is restricted, conditions common in North Hollywood’s mild winters when fires burn low and slow. A standard brush won’t remove it. We use mechanical removal methods and in some cases a chemical treatment, then re-inspect to confirm the flue surface is clean. If we find third-degree glaze, you’ll see it in our photos before we quote the removal. Call (833) 467-7685 to have your creosote levels checked.
Yes, and the reason is less about creosote and more about structural movement and pest intrusion. North Hollywood’s dry Valley heat and Santa Ana winds dry out mortar crowns and joints, and seismic micro-movement keeps working old masonry. Squirrels, birds, and bees move into idle flues during the warm months. A quick annual inspection finds a small problem before it becomes a chimney fire or a carbon monoxide leak. It’s cheaper than a liner replacement. Call (833) 467-7685 to book your annual check.
