Custom Composite Decks
Built for NH Living

Most composite deck projects in southern NH run between $85 and $100 per square foot installed. A typical 400 sq ft deck falls somewhere between $34,000 and $40,000 depending on materials, height, stairs, and railing. Premium boards from Eva Last or Deckorators cost more than entry-level options, but they carry longer warranties and hold up better over time. We give you a free written estimate so you know the full number before anything starts.

Composite is made from wood fibers and recycled plastic. It doesn't need staining, sealing, or painting and it holds up against rot, mold, and moisture. Pressure-treated wood is cheaper upfront but needs maintenance every year or two and will warp and splinter over time. Once you factor in the upkeep costs, composite usually comes out ahead after 10 to 15 years.

The brands we install, Eva Last, Deckorators, and Wear Decking, carry warranties ranging from 25 to 50 years on materials, fading, and staining. The boards are built for cold climates and handle freeze-thaw cycles without absorbing water the way wood does. Warranties are also transferable, which adds resale value when you sell your home.

Yes, in most NH towns you need a permit for any deck attached to the house or more than 30 inches off the ground. Requirements vary by town. We handle all of that for you. We pull the permits, submit the drawings, and make sure everything meets local code. You don't have to deal with the town office.

We install Eva Last, Deckorators, and Wear Decking by Owens Corning. Eva Last is a bamboo fiberglass PVC composite, Deckorators uses a mineral-based board, and Wear Decking is a marine-grade option. Each has different price points and looks. We'll walk you through the options during the estimate. We are also a certified pro or listed installer for Eva Last, Deckorators, and Fortress, which means we are held to higher installation standards.

Once we have the permit approved, most builds take 1 to 3 weeks depending on size. From your first call to the day we start, plan for 2 to 6 weeks to cover the estimate, permitting, and material lead times. We build April through November mostly, but off-season jobs are possible depending on the scope and weather.

We cover all of southern NH including Nashua, Manchester, Concord, Derry, Londonderry, Merrimack, Bedford, Hudson, Milford, Amherst, Windham, Salem, Pelham, Hollis, Goffstown, Hooksett, Bow, Weare, and the towns around them.
