Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Chimney Sweep Chino Hills Is Diamond Bar’s Preferred Chimney Sweep Company
Diamond Bar homeowners don’t need a sweeper from across the county. They need someone who understands what’s actually inside the walls and chases of 1970s and 1980s tract homes. That’s us. We’re based in Chino Hills, a short drive from Diamond Bar, and a good portion of our weekly routes run through 91789 and 91765.
Noel Strickland built this company around one principle: show the homeowner what we find before recommending anything. That means camera footage of the flue, photos of the firebox, and a plain explanation of what can wait and what can’t. Diamond Bar customers tell us that’s why they call back and refer us to neighbors. We don’t upsell liners and caps that aren’t needed. But when a prefab firebox is cracked behind the facade, we’ll show you the image on the spot, then talk through options using materials from brands like HeatShield and DuraFlex.
We keep our Diamond Bar route tight, which means if you call us on a weekday, we can usually get someone out within a week, often sooner. During Santa Ana season, we prioritize homes near canyon edges and steep brush-covered slopes along the 57 and 60.

Gas Fireplace Cleaning in Diamond Bar
Gas Fireplace Cleaning in Diamond Bar is one of the most requested services we handle, and far too many homeowners assume it’s unnecessary. It’s not just about soot. A gas log set produces acidic combustion byproducts that corrode burners, cloud glass, and leave a fine white residue in the flue. In Diamond Bar’s dry off-season, dust and insects also collect inside the firebox and pilot assembly. A thorough cleaning includes removing the logs, brushing the burner, cleaning the glass, vacuuming the firebox, and inspecting the vent for obstructions. Most gas fireplace cleanings in Diamond Bar run $149 – $219 depending on condition and access.
Vent Inspection and Carbon Monoxide Check
Gas fireplaces vent carbon monoxide outside, and a partially blocked flue or damaged vent cap changes that equation. We check the entire vent path, test for proper draft, and look at the termination cap on the roof or exterior wall. Chimneys on stucco-clad chases in Diamond Bar commonly develop cap rust and screen damage after heavy Santa Ana wind seasons, and that’s exactly the sort of thing we catch during a routine cleaning.
Burner and Pilot Service
If your gas fireplace lights slowly, flames unevenly, or produces a sulfur-like smell, the burner and pilot need attention. Spider webs inside the burner tube are a common culprit in Diamond Bar garages and living rooms, especially in homes near open hillside where insects are plentiful in summer. We clear the burner ports, clean the thermocouple and thermopile, and get the flame pattern back to normal.
Chimney Maintenance in Diamond Bar
Chimney Maintenance in Diamond Bar is the difference between replacing a $40 spark arrestor screen and replacing a $4,000 liner system. Every chimney we clean gets a visual inspection of the cap, crown, flue, and firebox, because the failure we see most in this city is not creosote buildup. It’s component deterioration on aging prefabricated systems that homeowners assume are masonry.
Level 2 Camera Inspection
When we find signs of damage during routine cleaning, or when you’ve just purchased a Diamond Bar home and have no service history, a Level 2 inspection is the right call. We run a camera up the flue and record what we see. Cracks in clay-tile liners, gaps in factory-built flue sections, a disconnected vent pipe, hidden nests: these all show up clearly. You see the footage. We explain it. Then you decide.
Spark Arrestor and Cap Replacement
Diamond Bar sits in a high brush-fire zone, and the county enforces spark arrestor requirements for homes near wildland-urban interface areas. Santa Ana winds routinely crack or tear old screens and displace caps. During maintenance we check the cap and screen on every visit and replace damaged components with products from Olympia Chimney, Gelco, or Famco. Not the thin stamped steel from a hardware store that rusts within two winters.
Trusted Brands We Service in Diamond Bar
We install and service liners, caps, and repair systems from DuraFlex, HeatShield, Gelco, and Copperfield, all recognized throughout the professional chimney supply industry. When a Diamond Bar flue needs relining or resurfacing, we’re not experimenting with import parts. HeatShield-certified resurfacing restores a damaged flue without a full teardown, and it’s a repair most sweep-only companies in this area can’t offer. DuraFlex flexible liners handle the crooked flue paths common in short factory-built stacks on sloped lots. Because we stock these product lines and keep common component sizes on hand, many Diamond Bar repairs happen in a single visit.

AfterCommon Chimney Sweep Problems We See in Diamond Bar Homes
- Prefab fireboxes mistaken for masonry: The 1970s – 80s tract homes in 91789 and 91765 were mostly built with factory-made metal fireplaces behind brick or stone facings. Homeowners skip inspections assuming they have a traditional fireplace, and cracks in the metal panels go unseen until heat or smoke leaks into the wall chase.
- Nests in uncapped flues: Birds and squirrels find their way into open flue tops on hillside streets off Diamond Bar Blvd during the long dry summer. A nest blocks draft, stretches out smoke, and dries into a fire hazard by fall.
- Cracked spark arrestors after Santa Ana events: The strong winds that rake through the 60 corridor each fall snap cheap screens and crack caps. A damaged arrestor stops doing its job, and nobody notices until embers threaten or a backdraft pushes smoke through the firebox.
- Hardened soot in seasonal fireplaces: When fireplaces sit unused from March to November in Diamond Bar’s heat, soot and creosote bake onto flue walls and turn crusty. A standard sweep still removes it, but it takes more labor and the right brush for the flue type, which is why pricing ranges slightly with condition.

FAQs About Chimney Sweep in Diamond Bar
Every year. Prefabricated metal fireplaces from the 1970s – 80s have a service life, and the components closest to heat degrade even if the flue is clean. An annual Level 1 inspection with your sweep, plus a Level 2 camera inspection every two to three years, is the minimum we recommend for Diamond Bar homes of this era. Call (877) 358-0941 to schedule yours.
Because most caps in Diamond Bar were installed decades ago with light-gauge steel screens that flex and crack under sustained wind load. The Santa Anas funnel through the 57 and 60 corridors and hit hillside homes hard. We replace damaged caps with heavier components from Gelco, Olympia Chimney, or Famco, sized for the wind exposure specific to your street.
Yes, we clean gas fireplaces regularly, and it is necessary. Gas logs produce corrosive residues, and spiders plug burner tubes, and dust builds up over the dry summer. A gas fireplace cleaning in Diamond Bar runs $149 – $219, and it’s also a chance to check the vent path for carbon monoxide safety. Call (877) 358-0941 to book.
Don’t try to burn it out or push it down the flue. Both are fire hazards. Call us. We remove nests during a standard sweep, show you the camera view of the flue afterward, and install a properly fitted cap with a spark arrestor screen so it doesn’t happen again. This is one of the most common calls we get from hillside Diamond Bar streets every fall.
Yes, but the reason in Diamond Bar is often different from colder regions. It’s not heavy creosote from daily burning. It’s the long off-season that lets nests form, soot harden, and components corrode unseen. A sweep plus a visual inspection once a year catches those issues before they become repair bills. Estimates are free; call (877) 358-0941.
