Fast, Reliable Chimney Repair Across Los Gatos
Chimney repair in Los Gatos typically runs $280-$1,800 depending on whether you need mortar repointing, brick replacement, or partial rebuilding, and most of our Chimney Repair jobs are scheduled within 48 hours and completed in a single visit. We’re familiar with the split character of Los Gatos housing, from the pre-1940 masonry fireplaces along Tait Avenue and University Avenue near downtown to the hillside zero-clearance units off Black Road and Alma Bridge Road in the 95033 ZIP. The mountain microclimate out there runs cooler and wetter from October through April than flatland Saratoga or San Jose just a few miles north, which means more burn days per season and faster deterioration of mortar joints and crown seals.

Our Chimney Repair Services in Los Gatos
Mortar Repointing
The 1989 Loma Prieta earthquake cracked and shifted masonry chimneys across Los Gatos, and the repointing jobs done in the early 1990s are now 30-plus years old. We’re seeing widespread mortar joint failure in the downtown flatlands, especially in the Craftsman homes near Main Street and the Victorians along Broadway. Our repointing removes failed mortar to proper depth, matches the original joint profile, and uses professional-grade refractory mortar rated for the thermal cycling these chimneys endure. Typical repointing in Los Gatos runs $380-$650 for a standard single-flue chimney.

Spalling Brick Repair
Spalling, where the brick face flakes off from freeze-thaw moisture penetration, is common in Los Gatos hillside homes where the 95033 microclimate delivers more wet-cold cycles than the flatlands below. The Lexington Hills and Black Road corridor see this earlier and more severely. We cut out spalled bricks, install matching replacements, and address the water source, usually crown cracks or failed flashing, so the repair lasts. Single-area spalling repair in Los Gatos typically costs $450-$780; multiple courses or structural rebuilding runs higher.

Chimney Waterproofing
Los Gatos gets enough winter rain, particularly in the hills, that unprotected masonry absorbs moisture all season. We apply vapor-permeable waterproofing sealers from professional-grade lines that let the chimney breathe while shedding water. This is preventive work that pays off most on chimneys already showing early efflorescence or minor cracking. Waterproofing a standard Los Gatos chimney runs $280-$420, and we recommend it after any repointing or spalling repair to protect the investment.

Flashing Repair
Step flashing and counterflashing around chimney penetrations fail faster in Los Gatos when roof pitch and hillside exposure combine to drive rain uphill. We’ve replaced rusted and improperly lapped flashing on homes from the Communications Hill-adjacent lower slopes to the steep pitches off Old Santa Cruz Highway. Our flashing work uses copper or galvanized steel from Famco and Copperfield, lapped and sealed to current code. Typical flashing repair in Los Gatos costs $320-$580, with complex rooflines or multiple penetrations at the higher end.
We also handle Chimney Cap & Crown in Los Gatos and full chimney rebuilding when the damage has gone past spot repair. And if your fireplace itself needs attention, our Fireplace Services in Los Gatos cover everything from firebox refractory panel replacement to gas log troubleshooting.

Trusted Brands We Service in Los Gatos
We stock and install professional-grade materials from Olympia Chimney, Famco, and Copperfield, with DuraFlex stainless liner sections and HeatShield refractory mortar carried on every service truck. This matters in Los Gatos because many hillside homes in the 95033 ZIP sit within CAL FIRE State Responsibility Areas, where spark arrestor specifications and liner integrity are subject to inspection. Using builder-grade or incorrect-gauge materials can leave a homeowner with a citation, an insurance problem, or worse. We document every installation with photos and a written verdict, and we source parts that meet or exceed California code so there’s no question when the inspector or adjuster asks.
Common Chimney Repair Problems We See in Los Gatos Homes
- Post-Loma Prieta mortar joint failure. The earthquake repairs of 1989-1992 used whatever materials and crews were available, and many of those mortar beds are now crumbling. We inspect for this specifically in pre-1940 homes near downtown Los Gatos.
- Zero-clearance unit end-of-life in 1970s-1990s hillside homes. Factory-built fireplaces in the Lexington Hills and along Alma Bridge Road are hitting or exceeding their 20-25 year rated service life, with refractory panel cracking and metal fatigue that looks like a masonry problem but isn’t.
- Corroded spark arrestors in CAL FIRE hazard zones. The 95033 hillside areas require 12-gauge wire with no opening larger than ½ inch. We regularly find older installations with wrong-gauge or rusted-through screens that fail both code and common sense.
- Crown cracks accelerated by wet-cold cycling. The mountain microclimate in Los Gatos hills produces more freeze-thaw stress on concrete and mortar crowns than flatland San Jose or Campbell, leading to water intrusion that destroys chimneys from the top down.
