Decks in Derry need to do more than look good—they need to survive four seasons of wear. We build with frost-rated footings, moisture-resistant framing, and rot-proof surfacing to prevent premature failure. From snow load calculations to proper drainage, every detail is handled by local pros who understand this region.

Want more than just a deck? We design full outdoor environments with grilling stations, patio roofs, storage zones, and screened enclosures that blend seamlessly into your home. From compact backyards to spacious properties, every structure is customized to suit your needs.
Derry has a wide range of home styles, from new subdivisions to historic properties with tight setbacks. We’re skilled at maximizing function and flow—even when space is limited. Our designers create layouts that work with your landscape, lifestyle, and budget, while keeping the build 100% code compliant.


Beaver Lake Area: Lakeside properties require slip-resistant surfacing, storm drainage, and strong footings—we design for both safety and scenery.

East Derry: Sloped terrain is common—we build terraced platforms and safe stair systems to navigate elevation changes without sacrificing space.

Hood Commons Area: Newer homes often call for modern designs—our composite builds here include built-in lighting, metal railings, and sleek covered roofs.
