Spark Arrestor Installation in Austin, TX

A spark arrestor is the mesh screen that keeps burning embers in — stopping them from escaping the flue and igniting the roof or brush. A cap is the lid that keeps rain and animals out. The arrestor protects the outside world from the fire inside; the cap protects the flue from the weather outside. They're frequently built into one fitting, which is why people confuse them, but the arrestor is specifically the code-sized screen, and we'll fit one to a cap you already have.

No screen over the flue even if a weather cap is present, embers or sparks seen leaving the chimney top, or an existing arrestor that's rusted through, torn, or sooted solid. A local burn code or insurer in a fire-prone area may also require one. Homes near trees, dry brush, or wildfire terrain, and anyone burning wood, have the most to gain from a working screen on every flue.

Under NFPA 211, the screen must be corrosion-resistant material with openings no smaller than 3/8 inch and no larger than 1/2 inch. The 3/8-inch minimum keeps the screen from sooting shut and choking the draft; the 1/2-inch maximum stops embers from escaping. That dual limit is what makes an arrestor an engineered fire part rather than just a cap collar. Some wildfire jurisdictions are stricter, so the local requirement governs if it's tighter.

Almost certainly, and often to a stricter standard than the NFPA baseline. In a designated fire-hazard 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. We confirm the local mesh-and-material rule, install to it, and document the screen size for your inspection or insurance file.

Burning embers can leave the flue and land on the roof or in surrounding brush, which over a combustible roof or near dry vegetation is a roof-fire or wildland-fire ignition source. It's an inexpensive screen that prevents an expensive fire — and if your top is open with no cap either, you're also taking in the rain and animals a cap would stop, which is why the two are often installed together.

Bolt-on and clamp-on screens and arrestor-caps exist, but the work is at the flue top on the roof, the mesh has to fall within the code size range, and the screen must seat to the tile or pipe and stay put in wind. A loose or wrong-mesh screen fails on the one thing it's there for — containing embers — so the fit and the mesh size both need verifying against the code that applies to you.

Almost certainly a mortar mismatch. Older central-Austin masonry uses soft lime mortar by design; if someone repointed it with modern hard Portland mortar, the joint is now stronger than the limestone around it, so the stone face spalls instead of the joint. We assess the original mortar, document the damage with photos, and repoint with a matched soft mix — the craftsmanship fix, not the fast one.

Yes. For a Travis County sale we run a full articulating-camera Level 2 scan of the flue and deliver a time-stamped video record with a signed certification report formatted for buyers, agents, and underwriters. It's the same protocol our technicians run nationally, so the report carries weight on either side of the transaction.

Precisely *because* the flue sits idle most of the year. Ten months of disuse is when debris, nests, and moisture accumulate; then you light it hard for a short, intense season. The annual pre-season sweep and inspection catch the slipped tile or clogged cap before the first fire fills the house with smoke. On a premium home, the documented report is the value, not just the brushing.

In Austin it's most often one or both, exposed by a flash-flood-grade downpour after months of dry weather. We diagnose the actual entry point with a leak inspection — crown cracks, a failed flashing seal, or porous masonry wicking water — and give you the photographed evidence before recommending crown repair, re-flashing, or waterproofing. We don't sell waterproofing to a problem that's actually a flashing gap.
