Spark Arrestor Installation in Alamo Heights, TX

Think of them as two different jobs. The spark arrestor is the mesh screen that traps burning embers inside the flue so they can't drift out and land on your roof or nearby brush. The cap is the lid overhead that keeps rain and animals from dropping in. So the arrestor guards the outside world from the fire within, while the cap guards the flue from the weather without. Manufacturers often build both into a single fitting, which is where the mix-up comes from, but the arrestor is specifically the code-sized screen — and our crew can add one to a cap you already own during the same visit.

A few clear signals: there's no screen across the flue even though a weather cap sits on top; you've watched embers or sparks drift off the chimney; or the arrestor you have is rusted through, torn, or clogged solid with soot. In fire-prone areas a local burn code or your insurer may require one outright. The homes with the most to gain sit near trees, dry brush, or wildfire terrain — and anyone who burns wood benefits from a sound screen on every flue.

NFPA 211 sets the spec: corrosion-resistant material with openings no smaller than 3/8 inch and no larger than 1/2 inch. That 3/8-inch floor keeps soot from clogging the mesh and choking your draft, while the 1/2-inch ceiling keeps embers from slipping through. Those two limits together are what turn a screen into an engineered fire component rather than a plain cap collar. Some wildfire jurisdictions go tighter, and where the local rule is stricter, it governs.

Very likely yes, and frequently to a tougher bar than the NFPA baseline. Inside a designated fire-hazard zone or wildland-urban-interface area, a single escaped ember is a genuine wildfire risk, so local code and many insurers mandate a compliant arrestor on every solid-fuel flue. Our team confirms the mesh-and-material rule that applies where you live, installs to match it, and records the screen size for your inspection or insurance file — one company handling the work and the paperwork together.

Live embers can ride up the flue and settle on your roof or in the brush around the house; over a combustible roof or near dry vegetation, that's an ignition point for a roof fire or a wildland fire. A modest screen heads off a very costly blaze. And if your flue is wide open with no cap either, you're also letting in the rain and animals a cap keeps out — which is exactly why we usually add the screen and the cap on the same trip.

Bolt-on and clamp-on screens, along with arrestor-caps, are out there, but the job happens up at the flue top on the roof, the mesh has to fall within the code size range, and the screen must seat firmly to the tile or pipe and hold in gusting wind. A loose or wrong-gauge mesh fails at its one purpose — keeping embers contained — so both the fit and the opening size have to be checked against the code that governs your address. That's rooftop work our crew handles on the same visit as the rest of your chimney service.

That's the whole design of it. Older homes interconnect in ways separate contractors miss — the chase that carries your original flue often carries duct runs and wiring too, and an uninsulated attic changes how the entire house breathes. We inspect chimney, ducts, dryer vent, and insulation in one pass and write it up as one prioritized report, so you're not reconciling four different opinions.

Maybe — many pre-war flues here are unlined or have cracked clay tiles, and you can't tell from the hearth. A camera inspection settles it in about twenty minutes. If it's sound, we document that and sweep it. If it needs a liner, we price it plainly and tell you what's safe in the meantime, which is sometimes nothing until it's fixed.

Inspection first, always — it sets the sequence. Typically: chimney safety items before burn season, attic air-sealing and insulation in spring or summer when it pairs naturally with duct sealing, and the dryer vent the same day as everything else since it takes the least time. Masonry repairs cure best in warm, dry months, so we slot those accordingly.
