Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Pomona, CA
Chimney repair in Pomona is different from what you’d find in coastal or mountain towns. The city’s early-1900s Craftsman bungalows and mid-century stucco tract homes hold original masonry chimneys with clay flue tiles that have spent decades in the San Gabriel Valley’s dry inland heat. That heat accelerates flue spalling, and when winter burn season hits, the same chimneys take on dense creosote in short windows. Walnut Chimney has served Pomona since 2017, and we repair what we find using the right materials for each job. Call (855) 341-3461 for a free estimate.
Why Pomona Homes Are Different
Pomona sits in the San Gabriel Valley’s smoggy inland basin, and that changes what builds up inside a chimney. Wood-burning fireplaces in the city’s older Craftsman and mid-century homes accumulate not just creosote but dense soot-and-ash fallout from frequent burn bans and the region’s trapped particulate air. The result is a buildup pattern distinct from what sweeps see in coastal or mountain towns: finer, stickier, and more likely to coat the flue walls unevenly. Many homes in the 91766 and 91767 ZIP codes still burn real wood during winter Spare the Air exemptions, giving Pomona a genuine, if episodic, wood-smoke season that neighboring foothill cities have largely lost.
The housing stock compounds the work. Downtown Pomona’s Craftsman bungalows carry original masonry fireplaces, often with clay flue tiles that cracked years ago and dampers that no longer seat properly. The 1940s-60s stucco tract homes across 91767 and 91768 were built with the same clay-tile flues, and many were later fitted with inserts that changed how the chimney drafts. Inland Pomona runs hotter and drier than the LA coast. The long dry season accelerates spalling on those old clay tiles, and the cool winter burn season concentrates creosote in a handful of burning weekends. Homeowners in the 91766 bungalow blocks also know the rainy-season downdraft problem: a smoky fireplace on a damp evening is often not a blockage but the classic Pomona cold chimney issue, where a cold masonry flue refuses to draft until it warms. We check for that specifically before recommending any repair.
Styles & brands we work with





Our Main Pomona Services
Most Pomona homeowners call Walnut Chimney for two reasons: a chimney that needs cleaning or a dryer vent that has quietly become a fire hazard. Both are safety work, and both are covered by one company.
Chimney Sweep in Pomona
A chimney sweep in Pomona means removing the creosote and soot-and-ash mix that builds up in this basin’s burn-season homes. We clean from the firebox to the cap, and we inspect every flue we sweep. In these older masonry chimneys, that inspection often turns up hairline clay-tile cracks or a damper that is stuck partially open. We document what we find with photos so you see it too. See Chimney Sweep in Pomona for a full rundown of what the job involves here.

Dryer Vent Cleaning in Pomona
Dryer vent cleaning in Pomona is a fire-safety service, not an add-on. The NFPA cites dryers as a leading cause of home fires, and the long dry season in this climate means lint dries out and becomes fuel quickly. Many Pomona homes have short interior vent runs, but we regularly find vents packed enough to restrict airflow. We clean the full run and confirm the exterior vent is clear. See Dryer Vent Cleaning in Pomona for details on our process in this area.

Chimney Repair in Pomona
Chimney repair in Pomona usually starts with one of two findings: a cracked clay flue tile spotted during a sweep, or a leaky chimney crown that has let water into the masonry. Both are common across the city’s early-1900s bungalows and mid-century tract homes, where original clay tiles have spalled under decades of inland heat and cool winter burns. The dry heat accelerates tile breakdown, and the short burn season concentrates creosote, so a small crack becomes a flue problem faster here than in coastal cities. Walnut Chimney repairs what we find, using professional-grade materials from brands like DuraFlex and Olympia Chimney, and we never recommend work without camera evidence you can see. Our Chimney Repair process is built around that transparency.
Chimney Cap Replacement
Signs you need it
You see rust flakes around the firebox, hear animal noise in the flue, or the old cap is visibly bent, rusted through, or missing entirely.
What it costs in Pomona
Chimney cap replacement in Pomona typically runs $280 to $530, pushed up when the existing cap is rusted onto a deteriorated crown that also needs work.
How we do it
We inspect why the old cap failed, source the right replacement from Famco or Olympia Chimney, remove the old unit, and mount the new cap to the crown with fresh fastening and a proper fit for your flue size.
Chimney Flashing Repair
Signs you need it
You notice water staining on the ceiling near the fireplace, damp brick around the roofline, or visible gaps and lifted sections in the metal flashing where the chimney meets the roof.
What it costs in Pomona
Chimney flashing repair in Pomona typically runs $390 to $780, with the price influenced by access difficulty on steep or multi-story roof lines.
How we do it
We remove the failed flashing, prep the joint, install new step and counter flashing sealed properly, and test the area to confirm water moves away from the chimney instead of into it.
Chimney Crown Repair
Signs you need it
You see cracking or spalling on the concrete crown at the top of the chimney, water pooling in its center, or brick erosion just below the crown line.
What it costs in Pomona
Chimney crown repair in Pomona typically runs $500 to $1,300, with full crown replacement on the higher end when the existing concrete has broken apart.
How we do it
We clean the crown, fill cracks and voids with a professional-grade repair compound, rebuild the surface with proper slope for water runoff, and seal the repair so rain and dry-season heat don’t reopen it.
What Chimney Repair Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Chimney cap replacement | $280 – $530 |
| Chimney flashing repair | $390 – $780 |
| Chimney crown repair | $500 – $1,300 |
How do I know my Pomona chimney actually needs repair?
A cracked flue tile or failed flashing is a measurable thing, not a judgment call. We show you camera footage before any repair recommendation, so you see the exact crack, gap, or spalled surface we’re proposing to fix.
Can a leaky chimney in Pomona wait until spring?
Water entry never improves with time. Inland heat and rain cycles widen cracks, and a small flashing gap in November becomes a ceiling stain by February. If you see damp brick or staining, call us before the rainy season does more work.
Brands We Service in Pomona

What Pomona Customers Say
"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Elena Salazar"Liner was cracked in two places. He walked me through the repair options honestly, including the one that was cheaper for him and better for me."
— Megan Ackerman"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
— Beatriz Vargas
