Spark Arrestor Installation in Katy, TX

A spark arrestor is the mesh screen that holds burning embers in, keeping them from escaping the flue and setting the roof or nearby brush alight. A cap is the lid that keeps rain and animals out. The arrestor shields the outside world from the fire within; the cap shields the flue from the weather outside. The two are often combined in a single fitting, which is where the confusion comes from, but the arrestor is specifically the code-sized screen, and we can fit one onto a cap you already own.

No screen over the flue even where a weather cap is present, embers or sparks spotted leaving the chimney top, or an existing arrestor that has rusted through, torn, or sooted solid. A local burn code or an insurer in a fire-prone area can require one as well. Homes near trees, dry brush, or wildfire terrain, and anyone burning wood, stand to gain the most from a functioning screen on every flue.

NFPA 211 requires the screen to be a corrosion-resistant material with openings no smaller than 3/8 inch and no larger than 1/2 inch. The 3/8-inch floor keeps the screen from sooting shut and strangling the draft; the 1/2-inch ceiling keeps embers from getting out. That two-sided limit is what makes an arrestor an engineered fire component rather than a plain cap collar. Some wildfire jurisdictions set stricter rules, so the local requirement controls whenever it's tighter.

Yes — and in these zones the requirement usually runs tighter than the NFPA baseline. Inside a designated fire-hazard or wildland-urban-interface area, one ember that escapes the flue can start a wildfire, which is why local code and a lot of insurers require a compliant arrestor on every solid-fuel flue. Our CSIA-certified techs verify the mesh-and-material rule your jurisdiction enforces, install to that spec, and record the screen size so it's on file for your inspection or insurer.

Embers that clear the flue can drop onto the roof or into nearby brush; over a combustible roof or beside dry vegetation, that's a live ignition point for a roof or wildland fire. The screen is cheap insurance against a costly fire. And an open top with no cap is also letting in the rain and animals a cap is designed to stop, which is why we frequently fit the arrestor and cap together.

Bolt-on and clamp-on screens and arrestor-caps are both available, but the work happens at the flue top on the roof, the mesh has to land inside the code-required size range, and the screen has to seat firmly to the tile or pipe and hold in wind. A screen that's loose or sized wrong fails at the one job it exists for — holding embers in — so we verify both the fit and the mesh size against the code that applies to your property.

Three things, top down: the cap, since gusts rack them loose; the chase cover or crown, for ponding and fresh seam leaks; and the flashing where chimney meets roof, because wind-driven rain enters sideways in ways ordinary weather never does. Interior staining can lag the storm by weeks, so don't wait for a ceiling spot. We photograph all three points, which gives you a record for insurance if it's needed.

Annual sweeping, usually no — gas burns clean. A regular inspection, yes, and here's the honest reason: gas flues still take on water, mud daubers still block vents, and a blocked or corroded gas vent is a carbon monoxide problem, which is quieter and more serious than creosote. It's a shorter, cheaper visit than a wood-burner's. We'll set the interval to match how you actually use it.

New shingles don't fix old chimney metal. On framed chases the usual culprit is the chase cover — builder-grade covers pond water, rust at seams and screw points, and drip down the flue pipe onto framing below. The stain sometimes shows up rooms away from the leak itself. A properly fabricated cover with a cross-break and drip edge ends it. We check the flashing too, since reroofing disturbs it.
