Deck Materials That Can Handle the Lehigh Valley

Built for Wind, Rain & Freezing Temps

Pennsylvania weather can be rough. That’s why we use trusted materials like Trex and TimberTech for composites, and pressure-treated or cedar lumber for natural builds. Every deck we install is made to breathe, drain, and hold up—through winter freeze, summer heat, and everything in between.

Not Just a Deck—A Better Backyard

Screened Porches, Roof Covers & Outdoor Additions

We design more than decks. From shade structures and grilling zones to bug-free screened-in porches, we build outdoor features that make your space more livable. Every project is customized to your layout, use, and comfort—whether you’re in downtown Bethlehem or outside city limits.
