Spark Arrestor Installation in Boerne, TX

NFPA 211 is specific: the arrestor's openings must not allow a sphere larger than 1/2 inch to pass, and must not block a sphere smaller than 3/8 inch. That window keeps the screen tight enough to catch embers while still letting the chimney breathe. A screen with oversized holes lets sparks escape onto the roof; one that's too fine clogs with soot and chokes draft. We install arrestors built to that 3/8-to-1/2-inch standard rather than generic hardware cloth.

Only if it's the wrong screen or it's left dirty. NFPA 211 requires the arrestor to have a net free area at least three times the chimney outlet, specifically so it doesn't strangle the flow of gases. A properly sized arrestor maintains draft; the real risk is neglect — soot and creosote accumulating on the mesh can blind it over a season. We size to that 3x rule and recommend the screen be checked at your annual inspection so it stays open.

For chimneys serving solid-fuel appliances, a spark arrestor is required under NFPA 211, and many local fire codes mandate them outright — particularly in wildfire-prone and wildland-urban-interface areas where an escaping ember can ignite a roof or brush. Beyond code, it's simply sound fire practice. We install corrosion- and heat-resistant arrestors that meet the material and opening requirements, because a rusted or undersized screen defeats the purpose it was put there for.

Yes, and it usually should be. Many quality caps integrate a code-compliant arrestor screen, so a single component sheds rain off the flue, blocks animals, and arrests sparks at once. The key is that the integrated screen still meets the 3/8-to-1/2-inch opening rule and the 3x net-free-area requirement — some decorative caps don't. We verify the arrestor specification on any combined cap so you get genuine ember protection, not just a lid.

Boerne's Hill Country setting and German limestone heritage produce two distinct inspection profiles: the historic masonry chimneys along Main Street and the large custom stone fireplaces of Cordillera Ranch and Esperanza. Our CSIA-certified inspectors run Level 2 video on the older Historic Main Street stacks, where original limestone and unlined flues predate modern code, and on the tall exposed chimneys of Cordillera Ranch, where wind-driven weather attacks crowns and flashing. Across Hill Country Village's wood-burning homes, we measure creosote against NFPA 211's removal threshold before it glazes. Spark Arrestor Installation is part of keeping that local housing stock safe, efficient, and up to code.
