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 Hills
A chimney sweep in North Hills typically costs between $189 and $329 for a standard fireplace cleaning with a Level 1 inspection. That range covers most of the mid-century ranch homes around Sepulveda Boulevard and Nordhoff Street. We’re Ontario Chimney, and we work throughout the 91343 and 91393 ZIP codes year-round. North Hills chimneys carry a specific history, and we know what to look for before we ever run a brush up the flue. Call (833) 467-7685 and we’ll walk you through what your fireplace actually needs.
Why Ontario Chimney Is North Hills’s Preferred Chimney Sweep Company
North Hills homeowners call us because we treat a chimney sweep as an inspection first. The neighborhoods east of Bull Creek and west of Sepulveda were built when clay-tile liners were standard, and most of those liners are now sixty or seventy years old. Al Vickers built this company around the idea that homeowners deserve to see what’s inside their flue before they’re asked to pay for repairs. When our technicians arrive in North Hills, they carry a camera system that goes through the entire stack, not just the firebox.
We’ve worked on fireplaces along Parthenia Street, in the blocks around Plummer Street, and up through the residential streets that dead-end near the Hansen Dam foothills. That local repetition matters. We know which North Hills homes tend to have offset flues, which ones were retrofitted with gas logs during the eighties, and which ones still vent into original clay tile that should have been lined decades ago. Our Chimney Sweep team shows up prepared for what your specific house is likely to contain.

Chimney Sweep Certified in North Hills
Chimney Sweep Certified in North Hills means we don’t just vacuum out the firebox and call it done. A certified sweep here starts with the assumption that a 1950s ranch home near the old aerospace corridors has a clay-tile flue that may have been compromised by the 1994 Northridge quake. The sweeping itself removes creosote, soot, and any debris blocking the stack. In North Hills, $189 to $249 covers that basic sweep with a visual Level 1 inspection for a typical masonry fireplace.
Creosote and Soot Removal
Creosote builds up differently depending on how you burn. North Hills fireplaces that burn mostly during December and January, then sit unused through the hundred-degree summer, develop a hard, glazed creosote that a wire brush alone won’t remove. We use rotary loop systems and chemical treatments when that hardened buildup is present. Expect first-degree creosote removal to be included in the standard sweep price; heavy third-degree glazing usually adds $80 to $140 and requires a longer appointment.
Annual Sweep and Fireplace Cleaning
An annual sweep is the baseline service we recommend for any North Hills home that burns wood at least once a week during winter. It takes about an hour for a standard single-story ranch, longer for two-story homes or fireplaces with engineered offsets. We lay drop cloths, run a HEPA-filtered vacuum, and leave the hearth cleaner than we found it. You’ll get a written condition report with photos of anything we found inside the flue.
Gas Fireplace Cleaning in North Hills
Gas Fireplace Cleaning in North Hills often uncovers problems that have nothing to do with soot. Many of the gas inserts and log sets installed in the eighties and nineties were vented into original clay-tile flues that were never sized or lined for gas exhaust. A gas cleaning here usually runs $149 to $199, which includes removing the glass, cleaning the burner and logs, checking the pilot assembly, and inspecting the vent connection. But the real value is the camera run we do through that vent path.
Gas Insert and Log Set Service
Gas appliances produce acidic moisture as a byproduct of combustion. Run that through a fifty-year-old clay flue and you get accelerated deterioration of the mortar joints between tiles. We see it regularly in North Hills homes off Woodley Avenue. The cleaning itself is straightforward, but we’ll always show you the vent condition on camera so you know whether the flue is doing its job or slowly venting into the attic chase.
When Gas Fireplace Cleaning Reveals Bigger Problems
If the camera shows cracked tile, missing mortar, or a flue that was never properly sized for the gas appliance, we’ll stop and explain it in plain terms. You’re not under any pressure to fix it that day. We’ll email the footage to you and give you a written quote. If a repair makes sense, our team handles it with HeatShield ceramic resurfacing or a DuraFlex liner, depending on what the specific flue requires.
Trusted Brands We Service in North Hills
The materials we install in North Hills homes come from the same distributors that supply certified chimney professionals nationwide. We use HeatShield for ceramic flue resurfacing when the clay tiles are cracked but the structure is sound, and DuraFlex flexible liners when an offset flue or a gas appliance needs a properly sized vent. Components like caps and dampers come from Famco and Copperfield, which carry professional-spec hardware you won’t find on a hardware store shelf. When we quote a repair for a North Hills chimney, we’re quoting materials we’d put in our own homes.

AfterCommon Chimney Sweep Problems We See in North Hills Homes
- Earthquake-cracked clay flue tiles. The 1994 Northridge quake epicenter was only a few miles from North Hills, and thousands of ranch homes absorbed that shaking. Hairline cracks in the terra cotta liner often don’t show from the hearth, but a camera sees them clearly.
- Gas inserts vented into unlined or cracked clay flues. This is the most common configuration we encounter in 91343. It was code-compliant enough at the time, but decades of acidic gas exhaust have eaten at the mortar joints.
- Chimney swifts nesting in uncapped flues. North Hills sits in the east San Fernando Valley, where chimney swifts arrive every spring. They’re protected under the Migratory Bird Treaty Act, so if they’re nesting, the sweep legally has to wait until the young have fledged.
- Hardened creosote from seasonal burning with long idle periods. A fireplace that burns hard through winter and then sits through triple-digit valley summers develops a glazed, tar-like creosote. It’s the most difficult to remove and the most fire-dangerous.
Pricing for Chimney Sweep in North Hills, CA
A standard chimney sweep in North Hills runs $189 to $249 for a wood-burning fireplace with a Level 1 visual inspection. Gas fireplace cleaning lands between $149 and $199. Most of the cost difference comes down to flue height, how heavy the creosote buildup is, and whether there’s a cap or damper that needs removal and reinstallation. If we find third-degree glazed creosote, expect $80 to $140 added for the chemical treatment and extra labor. You’ll always get a written flat price before any work starts, and we email you the camera footage from your inspection. Call (833) 467-7685 and we’ll give you a free estimate over the phone and a firm price before we arrive.

FAQs About Chimney Sweep in North Hills
The 1994 Northridge earthquake, with its epicenter just a few miles from North Hills, cracked clay-tile flue liners throughout 91343. Those hairline cracks are invisible from the firebox and can vent smoke and carbon monoxide into attic spaces. That’s why every sweep we perform in North Hills includes a camera run through the full flue, not just a brush-and-vac.
Our techs have seen enough post-quake chimneys to know where to look. If the camera catches a crack, we’ll show you the footage. Then we’ll talk about HeatShield resurfacing or a DuraFlex liner. Call (833) 467-7685 for an estimate with camera documentation.
No, and it’s not a choice we get to make. Chimney swifts are a federally protected species under the Migratory Bird Treaty Act, and in North Hills they typically nest from April through August. Any sweep who runs a brush through an active nest is breaking federal law, and we won’t do it. We’ll schedule a return visit after the young have fledged, usually in late summer or early fall.
We see swift nests most often in North Hills homes with uncapped flues. If you want to prevent the problem entirely, ask us about installing a proper chimney cap. Call (833) 467-7685 and we’ll check your flue for nesting before any cleaning is booked.
It depends almost entirely on the condition of that clay flue and whether it’s properly sized for the gas appliance. Many North Hills homes had gas inserts dropped into fireplaces originally built for wood, with the old clay liner left in place. Gas exhaust is acidic and attacks mortar joints, so a flue that was fine in 1995 may be deteriorating now. The only way to know is a camera inspection.
If the flue is cracked or the joints are failing, we’ll recommend relining with DuraFlex or resurfacing with HeatShield. If the camera shows a sound flue, we’ll tell you that too. Call (833) 467-7685 and we’ll show you exactly what your vent path looks like.
First-degree creosote is a light, powdery soot that brushes off easily and is included in any standard sweep. Third-degree creosote is a hard, glazed, tar-like coating that forms when a fireplace is burned hot and then left dormant through a long San Fernando Valley summer, which is exactly the pattern we see in North Hills homes. Third-degree creosote can’t be removed with a standard wire brush and requires chemical treatments or rotary tools.
It matters because glazed creosote is the type most associated with chimney fires. We’ll show you on camera which degree you have, then quote the removal accordingly. Call (833) 467-7685 for a sweep that separates real creosote from guesswork.
We provide a camera-assisted inspection with every sweep, but a formal Level 2 inspection, which includes attic and crawlspace access points and video documentation of the entire flue, is a separate service we recommend for any North Hills home that has never had one, especially after the 1994 quake or after any chimney fire or appliance change. A Level 2 inspection runs $249 to $399 depending on access complexity.
In North Hills, where earthquake damage is a real variable, a Level 2 is the standard we suggest before any liner work or major appliance venting change. Call (833) 467-7685 and we’ll help you decide whether a Level 1 or Level 2 is the right call for your chimney.
