Spark Arrestor Installation in Round Rock, 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.

Age doesn't exempt a flue; use pattern does. A twelve-year-old prefab that's burned every winter has accumulated creosote and, after ten idle months a year, debris and possible nests. The annual sweep verifies it's clear and the written report documents the firebox, liner, and cap condition. On a newer system the value is early-catch maintenance that keeps a good system out of the expensive-repair column.

Yes, and it's most of what we do in Round Rock. Factory-built (prefab) systems need a specific touch: poly brush heads on stainless liners, attention to the air-cooled chimney sections and firestops, and the manufacturer's clearance specs. We service all three fuel types — wood, gas, pellet — to the same documented standard.

Method selection, full-path cleaning, HEPA capture, and a photographed written report. The cheap special brushes the easy reach and leaves. We assess creosote stage, choose the correct head for your liner type, capture every particle so your home stays clean, and hand you documentation you can keep on file. You're paying for a verified-safe, recorded system.
