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 Walnut Chimney Is Pomona’s Preferred Chimney Sweep Company
Most Pomona homes were built between 1900 and 1970, which means original masonry fireplaces, clay flue tiles that have baked through decades of inland heat, and dampers that have not moved freely in years. We see these conditions every week. When we service a Pomona chimney, we’re not doing a generic sweep, we’re checking for the specific failure patterns this city produces: spalled clay tiles, glaze creosote from short hot burns, and dampers that need repair rather than replacement. That local knowledge changes what we look for and how thoroughly we clean.
We also treat chimney and dryer vent safety as one job. Walnut Chimney handles chimney sweeping, Chimney Sweep repairs, and dryer vent cleaning under a single call. If your dryer vent has not been cleaned in years, that’s a fire hazard sitting next to the chimney you’re already having serviced. We’ll catch both.
Every job, we work with professional-grade materials from brands like DuraFlex, HeatShield, and Copperfield, and if we find damage during the sweep, we can repair it with the right material for your specific flue, not whatever product happens to be in the truck. That’s the difference between a brush-and-go visit and a company that actually fixes what it finds.
Styles & brands we work with
Chimney Sweep Certified in Pomona
A Chimney Sweep Certified in Pomona means a full mechanical brushing of your flue from the firebox to the cap, plus removal of soot, ash, and creosote buildup, and a visual check of the damper, flue tiles, and cap. In Pomona, most wood-burning fireplaces need this yearly, and wood stoves used as primary heat need it more often. A typical sweep in Pomona runs $150 to $280 depending on flue height, creosote stage, and whether you have an insert. This includes basic cleanup and a Level 1 inspection.
Level 1 and Level 2 Inspection
Every sweep we do in Pomona includes a Level 1 inspection: a visual check of the accessible portions of your chimney from the firebox to the cap. We look for creosote stage, cracked flue tiles, damper function, and any obstruction. When a Pomona home has had water intrusion, a chimney fire, or when the dry inland heat has caused visible spalling, we recommend a Level 2 inspection, which includes a camera scan of the entire flue interior. You’ll see the photos. That’s the point: nothing gets replaced without you seeing the evidence.
Creosote and Soot Removal
Creosote is the real fire risk, not soot. Soot is dusty and gray; creosote is sticky, shiny, or glaze-hard, and it ignites at under 500 degrees Fahrenheit. In Pomona’s hot, dry summers, the clay flue tiles expand and crack, creating pockets where creosote collects. Then winter burn season glazes it. We remove first and second-degree creosote with mechanical brushing. Third-degree glaze, common on wood stoves used as primary heat in Pomona’s rural edges, requires chemical treatment followed by brushing, and cannot be scraped off without damaging the liner. We handle that too.
Gas Fireplace Cleaning in Pomona
Gas Fireplace Cleaning in Pomona is a different job from wood chimney sweeping, and we treat it that way. Gas fireplaces still need annual service: burner cleaning, log set removal and cleaning, glass cleaning, and venting check. In Pomona’s newer tract homes across 91767 and 91768, gas inserts and gas log sets are common, many of them never serviced since installation. A gas fireplace cleaning typically runs $120 to $200. It’s fast, and it matters: clogged burner ports cause uneven flame, soot on the glass, and in vented setups, incomplete combustion that a carbon monoxide detector may never catch.
Burner and Log Set Service
We pull the log set, clean the burner ports, remove accumulated dust and pet hair, and check that the pilot light assembly works. In Pomona’s dry season, dust from the foothills settles into burner trays and causes yellow flame and carbon buildup. A clean burner burns blue and even. That’s a measurable thing, and we show you before and after photos.
Venting and Draft Check
Gas fireplaces still vent, either through a B-vent, a direct vent, or in older homes, a converted masonry flue. In Pomona’s older 1920s Craftsman homes where a wood fireplace was converted to gas, the original clay flue liner was rarely replaced. We check for cracked tiles, blocked vent termination, and proper draft. If the vent is compromised, carbon monoxide can back into the living space, even if the fireplace looks clean. That’s why gas fireplace cleaning includes a draft check, not just glass polish.
Trusted Brands We Service in Pomona
We work with six professional-grade industry brands, and for Pomona customers, that means we can match the right material to your specific flue rather than forcing one product into every chimney. For liner jobs we use DuraFlex; for ceramic resurfacing we use HeatShield; for caps, dampers, and venting components we source from Copperfield, Gelco, Olympia Chimney, and Famco. When a Pomona chimney needs a cap replacement after rain intrusion, we’re not waiting on a mystery part. We stock common sizes and materials so the repair happens in one visit. That matters in a city where one winter rainstorm can push water into a cracked crown and stain your ceiling by the next morning.

AfterCommon Chimney Sweep Problems We See in Pomona Homes
- Third-degree creosote glaze in wood stoves. Pomona’s rural edges and older canyon properties still use wood stoves as real heat, not ambiance. Short, hot burn cycles produce a hard, shiny creosote glaze that brushes cannot remove. This requires chemical treatment, and skipping it leaves a fuel source primed for a chimney fire.
- Clay flue tile spalling. Pomona’s summers run hot and dry, and decades of thermal expansion and contraction crack the terra cotta liners in older masonry chimneys. We find spalled tiles in 91766 bungalows and 91768 ranchers constantly. Once the liner is compromised, the chimney is no longer safe to burn until repaired.
- Cold chimney downdrafts mistaken for blockages. The classic Pomona 91766 bungalow issue: you open a fire on a cool rainy night and smoke pours into the living room. It feels like a blockage, but it’s often just a cold flue and a chimney on an exterior wall that never warms up. We fix it with draft improvements, not an unnecessary cleaning.
- Unlined or under-lined gas conversions. Many older Pomona homes had wood fireplaces converted to gas decades ago without updating the flue. The original clay liner was built for wood heat, not gas venting. Corrosion and condensation from gas combustion accelerate liner decay. We see it often, and it’s why we recommend a camera inspection on every converted unit.

FAQs About Chimney Sweep in Pomona
In Pomona, if you burn wood more than twice a week during winter, schedule a sweep every 6 to 12 months. Pomona’s smog-basin location means burn bans interrupt regular burning, and when burning does happen, it’s often in short, hot windows that produce more creosote per burn than steady coastal burning. If you use a wood stove as primary heat on a rural Pomona property, plan on two sweeps per year, one after the first quarter of heavy use and one before the burn season starts. Call (855) 341-3461 and we’ll set a schedule that fits your burn pattern.
In Pomona’s older 91766 bungalows, smoky downdrafts usually come from a cold chimney, not a blockage. The flue sits on an exterior wall, cools overnight, and when you light a fire on a rainy evening, the cold air pushes smoke back into the room. It can also be caused by a chimney that’s not tall enough relative to the roofline, or a damper that’s stuck partially closed. We inspect first and sweep if needed; but we don’t sell you a cleaning for a cold chimney problem. We fix the draft and tell you the difference.
Yes, third-degree creosote glaze requires chemical treatment followed by a mechanical sweep, and we do both. It cannot be brushed off with a wire brush alone; the glaze is too hard and too flammable to leave. On Pomona wood stoves used as primary heat, this is the most common thing we find. We’ll apply the chemical treatment, return to sweep, and then show you the inside of your flue on camera so you know it’s clean. Call (855) 341-3461 to schedule.
Yes, we service gas fireplaces throughout Pomona, including the 91767 and 91768 tract homes where gas log sets and inserts are standard. That includes burner cleaning, log set removal, glass cleaning, and venting checks. Many of these units have never been serviced since they were installed, and in Pomona’s dry, dusty climate, that means clogged burners and uneven flame. A gas fireplace cleaning typically runs $120 to $200, and we show you the flame before and after.
We work with DuraFlex, HeatShield, Copperfield, Gelco, Olympia Chimney, and Famco. For Pomona homes, that means liner repairs use DuraFlex flexible liner systems, cracked flue interiors get HeatShield ceramic resurfacing, and chimney caps, dampers, and venting components come from Copperfield, Gelco, and Olympia Chimney. If we find damage during your sweep, we can repair it on the same visit with the right material for your specific chimney instead of referring you to another contractor.
