If you're tired of staining, sealing, or replacing warped boards, composite decking is the solution. At Alliance Deck Builders of Pennsylvania, we specialize in composite deck installation that looks great, stays safe, and cuts down on upkeep. We install top brands like Trex, TimberTech, and Fiberon with framing designed to support their weight and perform in Pennsylvania’s freeze-thaw cycles. Every deck is custom-fit, code-compliant, and finished with matching rails, stairs, and trims for a polished final product.

Why Homeowners Choose Composite Over Wood

Less Work, No Splinters, and Lasts Decades

Composite decks don’t just look clean—they stay that way. These boards won’t warp, rot, or crack like wood, and they require no sanding, staining, or sealing. That means more time enjoying your space and less time working on it. If you want a deck that stays cooler, resists moisture, and looks sharp for 20+ years, composite is the way to go. We’ll walk you through brands, textures, colors, and cost comparisons.

Moisture, Heat, and Freeze-Ready Materials

Pennsylvania weather can be hard on decks. Composite decking is built to handle it all—rain, snow, UV rays, and humidity. The boards resist swelling, cracking, and fading, while hidden fasteners and drainage-focused framing keep water away from your foundation. We build every deck with airflow, slope, and material spacing in mind to prevent long-term wear. You get a clean, strong structure that performs for decades—no annual upkeep required.

Composite Decks for New Builds or Upgrades

Start Fresh or Replace Your Old Deck Boards

Whether you're building from scratch or replacing old wood decking, we can install composite boards on new or existing frames. We’ll inspect your current structure for integrity and advise whether it’s a full rebuild or a surface-only update.If your framing is solid, we’ll prep and resurface with composite boards. If not, we’ll design and build a brand-new structure made to last. Either way, you get a flawless finish and warranty-backed materials.
