We’ve been driving to Pomona since 1984, long before the 10 and 60 freeways were the routes they are today. The inland valley climate here is different from coastal Los Angeles, and the chimneys show it. Winter nights in the 91766 and 91767 zip codes drop into the upper 30s and low 40s, cold enough that residents actually light fires - not just for atmosphere, but for warmth. Those fires put real demand on masonry that was built in the 1950s, 1960s, and 1970s and has rarely seen Chimney Cleaning & Sweep - Pomona professionals since. We know the tract homes along Mission Boulevard, the ranch-style neighborhoods south of Holt Avenue, and the postwar pockets near Ganesha Park where the original terra-cotta flue tile is now sixty years old and showing it.

Our Chimney Repair Services in Pomona
Mortar Repointing
The postwar ranch homes that dominate south and east Pomona were built with single-wythe brick masonry fireplaces and mortar joints that were never designed to last seventy years. In the 91766 zip code especially, we regularly find mortar that has turned to sand between bricks, letting water penetrate straight to the flue. Repointing removes the deteriorated material and packs fresh, properly matched mortar into the joints. A typical mortar repointing job in Pomona runs $850-$1,800 depending on access and how many courses need attention. Done right, it restores the structural integrity of the chimney and stops water intrusion before it reaches the flue liner and makes Chimney Liner & Rebuild in Pomona necessary.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is accelerated in Pomona by the inland valley’s wide temperature swings. Morning frost in January followed by afternoon sun in the 70s forces moisture trapped in bricks to expand and contract repeatedly. We see this most on valley-facing exposures where Santa Ana winds drive rain against the masonry. Spalling brick repair in Pomona typically costs $1,200-$2,800, including removal of damaged units, installation of matching replacement brick, and sealing to slow future deterioration. We source professional-grade materials from Olympia Chimney and Copperfield to ensure the repair blends and performs.
Chimney Waterproofing
Pomona’s combination of Santa Ana wind-driven rain and summer sun beating on south-facing chimneys makes waterproofing a practical investment, not an upsell. Our waterproofing treatment uses vapor-permeable sealers that allow the masonry to breathe while blocking liquid water - critical in a climate where trapped moisture would otherwise freeze and expand in winter. A standard chimney waterproofing in Pomona runs $400-$750 and carries the same 90-Day Done Right Promise as our rebuilds. We apply it after any needed repointing so the sealant bonds to sound masonry, not crumbling joints.
Flashing Repair
The junction where the chimney meets the roof is the most common leak point we find in Pomona’s older homes. Original flashing in 1960s tract construction was often galvanized steel that has rusted through, or was installed without proper step flashing behind the brick. Our flashing repair uses professional-grade materials from Famco and DuraFlex, custom-fitted to the roof pitch and chimney configuration. Typical flashing repair in Pomona costs $600-$1,400, and we complete most in a single visit with no return trip needed.

Trusted Brands We Service in Pomona
We do not substitute builder-grade materials to hit a price point. Our trucks carry professional-grade products from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - the brands that other chimney professionals specify for their own homes. For Pomona customers, this means faster turnaround because we are not waiting on special orders, and repairs that last because the materials were engineered for the thermal stress that inland valley chimneys endure. When we rebuild a crown or install a cap on a home near Ganesha Park or along Foothill Boulevard, we know the product will handle the Santa Ana exposure and the temperature cycling that comes with it.
Common Chimney Repair Problems We See in Pomona Homes
- Cracked terra-cotta flue tiles from thermal shock. The original flue liners in Pomona’s 1950s-1970s housing stock were never designed for decades of heating and cooling. Inland valley temperature swings cause these tiles to crack vertically, creating a path for heat and combustion gases to reach the surrounding masonry.
- Deteriorated mortar joints from decades of deferred maintenance. Many Pomona homeowners have never had a chimney inspection. By the time we arrive, the mortar has eroded to a depth of an inch or more, and individual bricks are loose in the wythe.
- Bird nests and debris blockages from Santa Ana wind exposure. Technicians working in Pomona consistently find bird nests and wind-driven debris packed into uncapped chimneys on valley-facing exposures - a direct result of the strong Santa Ana funneling effect specific to this inland basin. This problem is far less common in the shielded neighborhoods of neighboring Claremont or La Verne just a few miles away.
- Rusted or inoperable dampers in original fireplaces. The throat dampers installed in Pomona’s postwar homes were steel castings that rust solid after fifty years of moisture exposure. A stuck-open damper wastes conditioned air year-round; stuck-closed, it prevents fireplace use entirely.
