What we do

Our Decking Services in Brentwood, PA

Custom Deck Design & Installation

Every deck project begins with a design tailored to your home and yard. Whether you need a ground-level platform or an elevated deck, we engineer each structure for safety, longevity, and everyday use.

Composite Decks

Composite decking is ideal for homeowners who want minimal maintenance and long-term performance. It resists moisture, fading, and splintering, making it a strong choice for Western Pennsylvania’s seasonal weather.

Deck Repairs and Restoration

If your existing deck shows signs of wear or structural issues, we provide professional repair and restoration services. We handle:
    • Replacement of rotted or damaged boards
    • Railing and stair repairs
    • Structural reinforcement and support repairs
    • Resurfacing and resealing

Pressure-Treated Wood Decks

For a traditional appearance and cost-effective option, pressure-treated wood decks provide natural warmth and versatility. We build sturdy wood decks that can be stained or sealed to match your home’s exterior.

Railings, Lighting, and Custom Features

Enhance the function and appearance of your deck with optional upgrades such as:
    • Composite or aluminum railings
    • Built-in seating or storage
    • Low-voltage lighting systems
    • Privacy screens or pergola additions

Not only were Sam, Calvin and their crew reliable, responsive, professional, and extremely talented craftsman, they were also a joy to have around. We had a vision, and they nailed it, and quite honestly, they were better than we could have ever hoped. We are already discussing future projects.”

Sam was very knowledgeable about products and made great recommendations regarding our back deck replacement.
