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 Lennox
A chimney sweep in Lennox typically runs $160 – $290 for a standard cleaning with a Level 1 inspection, and most jobs are completed in under two hours. We service every block of the 90304 zip code, from the duplexes off Hawthorne Boulevard to the bungalows near Lennox Park.

Our Chimney Sweep crews know this area because they work it constantly. Tight lot spacing, low-pitch roofs, and mid-century masonry fireplaces all shape how we approach a job here. We carry the right ladders, the right brushes, and the right repair materials for Lennox housing stock, not for some generic Southern California average.
Why Corona Chimney Sweep Is Lennox’s Preferred Chimney Sweep Company
Lennox is a small, densely built unincorporated pocket of LA County. That creates a specific set of chimney conditions, and we’ve learned them the only way you can: by working hundreds of jobs here. Most homes are 1940s – 1960s stucco bungalows and small duplexes with original clay tile flues. Many of those flues have never been relined. Many are capped and sealed because a previous tenant or landlord decided the fireplace was more trouble than it was worth. We know how to sort all of that out without wasting your time or billing for work that isn’t needed.
A lot of our Lennox work comes from referrals. Neighbors tell neighbors when a crew shows up on time, explains what they found in plain English, and doesn’t invent problems to pad an invoice. Nolan Ferris built this company around that principle: we repair what we find, nothing more, and we show you the evidence before we ask you to spend a dollar on repair work.
Styles & brands we work with





Chimney Sweep Certified in Lennox
Chimney Sweep Certified in Lennox means the technician knows what to look for in a 1950s clay-tile flue that has spent decades absorbing marine-layer dampness and intermittent winter rain. The job involves removing creosote and soot from the flue walls, clearing debris from the smoke shelf and firebox, checking the damper for operation, and inspecting the flue liner, mortar joints, crown, and flashing for damage. Every sweep we do includes a Level 1 inspection. If conditions point to a deeper problem, we’ll recommend a Level 2 inspection, which uses camera equipment to look inside the flue.
A standard sweep with Level 1 inspection in Lennox runs $160 – $290 depending on flue height, accessibility, and how long it’s been since the last cleaning. First-time cleanings on a fireplace that hasn’t been touched in years often land at the higher end because of debris volume.
Creosote and Soot Removal
Creosote forms when wood smoke cools and condenses on flue walls. Even light seasonal burning produces first-degree creosote, a fine, dusty film that can still ignite under the right conditions. We remove it with rotary brushes and hand tools sized to your flue tile.
Annual Sweep Maintenance
If you burn even a dozen fires a year, an annual sweep is the simplest way to catch problems before they become structural. Lennox homeowners who follow an annual schedule rarely deal with mid-winter smoke backup or the kind of damage that requires a five-figure rebuild.
Gas Fireplace Cleaning in Lennox
Gas Fireplace Cleaning in Lennox gets overlooked constantly because people assume a gas fire is inherently safe and clean. It’s true that gas produces no creosote, but it does produce soot, mineral deposits on the glass, debris in the burner ports, and dust that settles inside the firebox during the long dry season. A clogged burner or a vent that’s partially blocked is a carbon monoxide risk, not just an aesthetic complaint.
We clean gas logs, fireboxes, blowers, and venting on gas inserts and freestanding gas stoves throughout Lennox. Expect to pay $140 – $240 for a thorough gas fireplace cleaning that includes burner inspection and vent verification. If your gas fireplace hasn’t been serviced in two or more years, it’s due.
Vent Verification for Lennox Homes
Because so many Lennox fireplaces were converted or sealed when gas appliances took over, we always verify the venting path before cleaning. A chimney that used to serve wood can vent a gas insert, but a flue that’s been capped or drywalled over needs to be addressed first. Skipping this step is how you end up with carbon monoxide backing into a living room.
Burner and Log Cleaning
Gas logs collect dust and soot that alter the flame pattern and can clog ports. We remove the logs, clean the burners with compressed air and soft brushes, clear the pilot assembly, and polish the glass. You’ll notice the difference in flame quality on the next burn.
Trusted Brands We Service in Lennox
We install and service venting components from DuraFlex, HeatShield, and Olympia Chimney. DuraFlex stainless flexible liners handle retrofit applications on older Lennox chimneys where rigid systems can’t make the bends. HeatShield resurfacing restores deteriorated flue interiors without a full liner replacement when conditions qualify, which matters on a 1950s clay-tile flue that’s losing mortar joints. We keep common repair parts stocked for faster turnaround, and anything we don’t have on the truck we can usually source within days, not weeks.

AfterCommon Chimney Sweep Problems We See in Lennox Homes
- Sealed or drywalled-over fireplaces. A surprising number of Lennox fireplaces were capped by previous owners or landlords. Before any cleaning, we verify that the flue actually vents somewhere and that no gas appliance has been routed into a dead chimney.
- Spalling brick and eroding crowns. The marine layer that rolls through Lennox keeps exterior masonry damp for months at a time. That moisture soaks into brick and concrete, then expands during heat cycles. The result is flaking brick faces and crumbling mortar crowns that let water straight into the flue.
- Leaf litter and bird nests. Tight lot spacing puts chimneys under a canopy of mature trees, and Lennox rooftops catch a lot of debris. We pull nests, leaves, and tennis balls out of flues regularly, sometimes two or three years’ worth.
- Hidden creosote in the smoke chamber. Even fireplaces that only get used on holidays accumulate first-degree creosote in the smoke chamber, where it’s invisible from below. That’s the stuff that ignites in a chimney fire. A visual firebox check never catches it, which is why a proper sweep includes getting up on the roof and working the full flue length.

FAQs About Chimney Sweep in Lennox
Once a year, even with light use. First-degree creosote accumulates from every wood fire regardless of how few you burn, and a single season of intermittent burning is enough to leave a combustible film in the smoke chamber. For gas-only fireplaces, an annual cleaning plus a vent check is enough for most Lennox homes. Call (855) 382-6159 to schedule a sweep and we’ll tell you honestly whether you even needed it yet.
Usually yes, but it starts with verification, not sweeping. We need to confirm the flue is intact, uncapped at the top, and not being used to vent a furnace or water heater. That’s a step we take on every sealed Lennox fireplace before touching a brush to the flue. If the flue is sound, we’ll clear it, inspect the liner, and get you burning again. On a 1950s stucco bungalow near the corner of 104th and Firmona, we found a drywalled-over firebox with a capped clay flue liner. After verifying no gas appliance vented into the flue, we removed the cap, swept out years of leaf litter and a bird nest, and installed a new stainless cap with a spark arrestor. The homeowner could finally use the fireplace without smoke backup. Call (855) 382-6159 and we’ll do the same for yours.
That’s efflorescence, and it’s the first visible sign of moisture moving through the masonry. The marine layer that settles over Lennox keeps chimney blocks damp for much of the year, and when water evaporates out of the brick, it leaves mineral salts on the surface. The fix isn’t scrubbing it off, it’s addressing the water entry, usually at the crown or flashing. Left alone, efflorescence turns into spalling, and spalling turns into structural repair. Call (855) 382-6159 and we’ll tell you what’s actually going on.
Yes. We clean gas fireplaces, gas inserts, and freestanding gas stoves throughout Lennox, including the 90304 zip code and the duplex-heavy blocks off Hawthorne Boulevard. Gas fireplace cleaning runs $140 – $240 and includes burner inspection, log cleaning, glass polishing, and vent verification. If your flame is yellow and lazy or the glass is filmed over, it’s time. Call (855) 382-6159 for a fixed quote.
First-degree creosote is a fine, dusty film that brushes off easily with standard sweeping tools. Third-degree creosote is a hard, tar-like glaze that has baked onto the flue walls and can’t be removed with brushes alone. It’s the most combustible form and the one most likely to support a chimney fire. On older Lennox chimneys that haven’t seen a sweep in years, third-degree creosote is common, and we use mechanical rotary tools to break it down, then assess whether liner repair is needed. Call (855) 382-6159 and we’ll tell you which degree you’re dealing with.
