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 Pomona
A chimney sweep in Pomona typically runs $169 – $279 for a standard wood-burning fireplace, with Level 2 inspections adding $150 – $250 when the flue needs a camera look. Most sweeps take 45 – 90 minutes. If you’re in a 1920s bungalow near Lincoln Park or a 1960s ranch off Garey Avenue, the flue inside your chimney was built long before modern liner standards, and that changes what a proper cleaning involves. Ashwood Chimney Sweep works throughout Pomona, and we know these houses because we’ve been inside enough of them to recognize the difference between routine creosote and a flue that’s quietly falling apart. Call (833) 805-3229 for a free estimate.
Why Ashwood Chimney Sweep Is Pomona’s Preferred Chimney Sweep Company
Norm Castillo leads our crew, and he’s built the company around a simple position: a sweep should be able to actually fix what the inspection finds, not just document it and hand you a referral. That’s why our trucks carry DuraFlex liner components, HeatShield restoration material, and Copperfield-sourced repair parts rather than whatever’s on the shelf at a hardware store. Pomona homeowners with older clay-tile flues need a company that can move from cleaning to repair without a second crew and a second estimate. We’re stocked for that.
Our reputation in Pomona comes from repeat customers in neighborhoods like Westmont and Phillips Ranch who’ve had us back year after year, and from the fact that we treat dryer vent cleaning as an equal fire-safety service, not a footnote on the invoice. When a Pomona homeowner books a sweep, they’re getting an assessment of the whole ventilation picture: flue condition, chimney crown, cap, smoke chamber, and the dryer exhaust that runs through the same wall cavities. One call, one visit, and a clear report on everything we found.
Our service radius includes all four Pomona ZIP codes: 91768, 91769, 91797, and 91766. We know which streets have tight driveway access in historic districts and which east-side tracts have roof pitches that make ladder setup straightforward. That local familiarity means we arrive prepared, not figuring it out on your front walk.

Fireplace Cleaning in Pomona
Fireplace Cleaning in Pomona means removing creosote from the smoke chamber and flue walls, clearing out ash and debris from the firebox, and checking that the damper opens and seals the way it should. In Pomona’s housing stock, much of it built between the 1920s and the 1970s, that cleaning almost always uncovers something the homeowner hasn’t seen in years: a cracked firebrick, a rusted damper, or first-degree creosote that’s been sitting since last winter. Our Chimney Sweep team handles all of it in a single visit, and a standard cleaning here runs $169 – $279 depending on flue height and creosote volume.
How Creosote Behaves in Pomona’s Dry Climate
Pomona’s hot, dry summers bake creosote into a hard, glassy layer that’s harder to remove than the flaky buildup you’d find in a coastal climate. When Santa Ana winds pick up in the fall, that glazed creosote becomes exactly the kind of fuel a chimney fire needs. We see this every October on the east side, off streets like Towne Avenue and Reservoir Street, where fireplaces sat unused through a long dry spell and the creosote cured into something a standard brush struggles to break loose.
Gas-Converted Fireplaces Still Need Sweeping
A gas log set doesn’t produce wood smoke, but the flue behind it is still open to the outside. Birds nest in the clay tile, leaves drop through a missing cap, and debris collects until the vent stops drafting properly. Before first fall use, that flue needs to be cleared. We clean gas-converted fireplaces in Pomona regularly, including many in the Lincoln Park historic district where the original 1920s brick fireplaces now have gas inserts venting through the same unlined flue they’ve used for a century.
Chimney Services in Pomona
Chimney Services in Pomona go beyond sweeping to cover the structural and safety issues that older masonry chimneys develop: deteriorating mortar crowns, cracked clay liners, missing chimney caps, and spalled brick. In Pomona, where so many homes have original chimneys dating to the 1920s – 1950s, these aren’t rare problems. They’re the normal condition of a flue that’s been exposed to summer heat, seismic movement, and Santa Ana winds for seven or eight decades. A Level 2 camera inspection costs $150 – $250 and gives us a clear view of what’s happening inside the flue, not just what’s visible from the roof.
Masonry Crowns and Seismic Cracks
The mortar crown at the top of a brick chimney takes the worst of Pomona’s weather. Summer heat expands it, winter nights contract it, and any crack that opens lets water seep into the brick below. Over time, the crown spalls and the bricks loosen. We inspect every crown during a sweep and repair those that are actively letting water in. On older Pomona bungalows near downtown, cracked crowns are the most common defect we flag.

HeatShield Restoration for Failing Liners
When a clay flue liner cracks, the old fix was a full liner replacement at thousands of dollars. HeatShield gives us a different option: a cerfractory sealant that restores the liner’s integrity without tearing out the chimney. It’s a repair method most sweep-only companies can’t offer because they don’t carry the product or the training. For Pomona homeowners whose older flues are still structurally sound but showing minor cracking, it’s often the difference between a $1,000 repair and a $6,000 rebuild.

Trusted Brands We Service in Pomona
We don’t install bargain-bin parts. Our repair materials come from Copperfield and Olympia Chimney, two of the most established professional chimney supply houses in the trade, and we use Famco components for dryer vent work. When a Pomona homeowner needs a liner repair, we’re installing a DuraFlex system, the same flexible liner specified by certified chimney contractors nationwide. We keep common components stocked so a Pomona repair doesn’t wait on a parts shipment, and our crews are trained on these specific products. If you already have a DuraFlex or HeatShield system, we’re familiar with how they wear and how to service them.
Common Chimney Sweep Problems We See in Pomona Homes
- Shared-stack cross-contamination: On Pomona’s older attached blocks around downtown and Lincoln Park, two homes often share one masonry chimney. When one neighbor burns wood and the other has converted to gas, smoke and creosote odor can push through cracks in the shared flue wall and into the adjacent home. Sweeping one side without inspecting the other is how cross-contamination stays in place.
- Baked-on first-degree creosote: Pomona’s dry summer heat cures creosote into a hard glaze rather than leaving it flaky and easy to remove. By the time Santa Ana season starts, that glaze is fuel-ready. A standard single-pass brushing won’t get it all; our crews use rotary tools and chemical treatments when needed.
- Crumbling mortar crowns on 1920s – 1940s chimneys: The original brick chimneys in Pomona’s Craftsman and Spanish Revival homes are nearing the end of their service life. Summer heat cycles crack the crown, water gets in, and the brick face starts spalling. This is a structural issue that a sweep alone won’t fix, and it’s one we flag in nearly half of the older homes we inspect near Garey Avenue and Holt Boulevard.
- Gas-converted fireplaces with unlined flues: Many Pomona fireplaces were converted to gas decades ago while still venting through the original unlined clay-tile flue. No wood smoke doesn’t mean no buildup: animal nests, leaves, and old creosote from decades of wood burning are still in there. The flue needs cleaning and a Level 2 inspection before the gas set runs in the fall.

FAQs About Chimney Sweep in Pomona
Yes. A shared masonry stack is one structure with two flues, and creosote, debris, and odors travel through any crack or gap between them. If one side gets swept and the other side doesn’t, the unswept flue keeps pushing creosote odor and smoke through the shared wall and back into the clean home. In Pomona’s attached bungalows around Lincoln Park and downtown, we recommend both sides be swept at the same time, and we’ll inspect both fireboxes in one visit. If your neighbor isn’t sure, call (833) 805-3229 and we’ll walk through what a shared-stack inspection actually involves.
Yes. Gas log sets produce no wood smoke, but they also produce no draft strong enough to clear out what accumulates in the flue: bird nests, leaves, old creosote from decades of wood burning, and falling mortar. In Pomona’s older homes, the flue behind a gas-converted fireplace is almost always the original unlined clay tile, which means debris collects faster and is harder to see. We clear the flue, inspect the tile, and check that the damper is set correctly for gas venting before you light the logs in the fall.
Third-degree creosote is a hard, glassy layer that forms when creosote goes through repeated heating and cooling cycles. It’s concentrated fuel, and it’s the form most likely to sustain a chimney fire. Pomona’s Santa Ana winds drop humidity into the single digits and turn any spark or elevated flue temperature into a serious risk. While first- and second-degree creosote can often be removed with standard rotary brushing, third-degree buildup may require chemical treatment or, in some cases, a liner restoration. We’ll show you exactly what’s in your flue on the camera. Most Pomona homes we see have first-degree creosote; the glazed stuff shows up when a chimney hasn’t been swept in five-plus years or when someone burned wet or resin-heavy wood.
This is one of the most common challenges on Pomona’s historic blocks around downtown and Lincoln Park, where homes sit close together and side yards are narrow enough that a standard ladder won’t set up cleanly. Our crews use adjustable extension ladders, roof stand-offs, and sectioned access equipment that can be carried through a side gate. We also work from the roof surface directly when the pitch allows it. Before we book a sweep on a tight lot, we ask about access and plan the setup, so we’re not improvising when we arrive. If a homeowner knows the neighboring lot is fenced or the side yard is blocked, we’ll bring what we need to work from the front elevation instead.
Yes. A cracked or spalled crown changes the airflow at the top of the flue, letting wind push down instead of drawing up. In a shared or adjacent flue, that backpressure can force the neighboring home’s exhaust into your fireplace, which is exactly the kind of cross-contamination we see on Pomona’s older attached blocks. We repair crowns with a proper bonded mortar mix, not a quick patch, and we’ll cap the flue to keep debris and animals out. Call (833) 805-3229 and we’ll assess the crown while we’re on the roof for the sweep.
The Shared-Stack Problem Pomona Homeowners Don’t Know They Have
Pomona’s dense older blocks, especially around Lincoln Park and downtown, pack attached and closely spaced homes whose fireplaces often share or abut a single masonry stack. That’s a structural arrangement that most chimney sweep pages never mention, because most cities don’t have Pomona’s concentration of pre-war attached housing. Here’s what it means in practice: a neighbor’s gas conversion or wood-burning appliance can vent smoke and creosote odor back through your flue, even when your damper is closed. The masonry between two flues in a shared stack is often only a single brick thick, and after 80 to 100 years of thermal cycling, hairline cracks open in the mortar. Sweeping one side of a shared stack without inspecting the other is how cross-contamination starts, and it’s also how a sweep gets blamed for a problem that was never actually solved.
On a tight Lincoln Park block, our tech answered a call about a kerosene-like odor backing into a 1920s Spanish Revival living room whenever the next-door fireplace was lit. Pulling the damper and running a Level 2 inspection on the shared masonry stack, we found a crumbling mortar chimney crown and a missing chimney cap letting debris and cross-draft into both flues, plus first-degree creosote glazing the smoke chamber. We swept both sides of the stack, capped it, and the neighbor’s smoke stopped migrating into the house. That’s not a job a single-firebox sweep would have caught, and it’s the kind of local knowledge that matters when you’re deciding who to call in Pomona.
