Our Decks, Porches & Outdoor Builds
From steep hillside decks in Pittsburgh to modern backyard retreats in Lancaster, our portfolio showcases the craftsmanship and creativity we bring to every outdoor living project. Each space is designed to meet the unique challenges of Pennsylvania properties — whether it’s handling heavy snow loads, maximizing tight urban spaces, or integrating with historic architecture.
Decks Built for Northeast Weather
Materials & Craftsmanship That Endure
From icy winters to humid summers, Pennsylvania’s climate demands smart building practices and high-performance materials. We use moisture-resistant lumber, stainless steel fasteners, and composite boards that won’t crack, warp, or rot. Every project is engineered for snow loads, drainage, and long-term durability — and our finishes are chosen to withstand the elements, not just look good on day one.

We Know Pennsylvania’s Building Rules
Every city in Pennsylvania has its own deck rules — and we know them well.

Our team works directly with zoning offices, inspectors, and HOAs to keep your project moving. You get peace of mind, clear communication, and a finished product that’s up to code.
Made to Handle Snow, Sun & Time
Weather-Resistant Materials That Last
We use materials built to withstand Pennsylvania’s extremes — freezing winters, humid summers, and rapid spring thaws. That means pressure-treated framing, snow-rated fasteners, and low-maintenance composite decking that won’t crack, fade, or rot. Every project is built with seasonal durability in mind — so you can enjoy your deck year after year without costly repairs.
