Chimney Sweep in Los Gatos, CA

Frequently Asked Questions

The glass doors on our old firebox are warped and the gasket is shot — repair or replace?

It depends mostly on the frame. On the older Craftsman and Victorian fireboxes around town, a lot of the doors we see are aftermarket units added decades after the house was built, and if the frame is still square and the mounting is sound, we can usually rebuild them: new gasket rope, new glass, new latch hardware, sometimes new hinge pins. Once the frame itself has warped from heat or the masonry behind it has shifted, repair stops being worth it, because the door won't seal against an out-of-plane opening no matter what gasket goes in. Wood insert and stove doors are a different call — those are model-specific, and whether parts still exist for a stove that's been in a Los Gatos living room since the 80s decides it. We'll tell you which situation you're in before touching anything.

What tends to be wrong with chimneys in older Los Gatos homes?

Three things dominate. First, unlined brick flues — plenty of the pre-1940 stock here was built with no clay liner at all, just brick and mortar, and after a century the joints have opened up. Second, seismic cracking; we regularly find stepped cracks in stacks and separation where the chimney meets the roofline. Third, real creosote. Because it's cooler and wetter up here than down on the valley floor, people actually burn, and a tall unlined stack with regular use builds glazed deposits that a once-a-decade look-over won't catch. Hillside and canyon homes toward Kennedy Road add a fourth: crowns and caps buried in leaf litter and needles from the tree canopy.

How fast can you get out here, and do you ever do same-day?

Same-day happens, usually when we already have a crew on the west side of town and your issue is straightforward — a smoke problem, a cap that blew loose, a sweep on a flue we've seen before. Standard scheduling is normally within a few days. Two things stretch that. One is the first stretch of real rain, when everybody discovers their flashing leaks at once. The other is access: canyon driveways and steep hillside roofs above town take longer to set up on safely, and if the roof pitch means we're bringing extra fall protection, we'd rather book it properly than rush it. If it's an active leak or you smelled something burning that wasn't the fire, say so when you call and we'll triage it.

Why do we keep getting water stains near the chimney after storms?

Almost always flashing, and Los Gatos gets more rain and more wind than the flats a few miles east, so the water arrives sideways. On older homes the flashing was often bedded into mortar joints that have since eroded, or it's been reroofed around two or three times and the last layer was caulked instead of properly stepped in. The other common source is the crown — a cracked crown lets water into the brick, and it shows up on the ceiling well away from the actual entry point. Debris from overhanging oaks and redwoods holds moisture right on the crown and makes it worse. We look at crown, cap, flashing and the top few feet of masonry together, because fixing one and ignoring the others just moves the stain.

What drives the cost up or down on a Los Gatos chimney?

Height and access, more than anything. The tall stacks on the older homes in the flats near downtown mean more rod length and more time, and hillside properties often mean a harder roof setup or a long carry from where we can park. Usage matters too: a flue that gets burned in all winter with an insert has genuine creosote to remove, and glazed deposits take longer than light soot. And an unlined century-old flue changes the conversation entirely, because at that point we're talking about what it needs to be safe, not just cleaning it. A straightforward sweep and inspection on a maintained flue sits at the low end. We look first, then tell you what we found and what it takes.
