Why Composite?
Why Composite Decking?
NH winters are rough. Wood warps, splinters, and needs work every year. Composite holds up without the upkeep.
Get Free Estimate- No Maintenance
No staining, sealing, or painting. Ever. Hose it off once in a while and it looks the same as day one.
- Handles NH Winters
Composite boards go through freeze-thaw cycles without warping, cracking, or soaking up water the way wood does.
- 25 to 50 Year Warranties
The brands we install carry 25 to 50 year warranties on materials, color, and stain resistance. They are transferable, so your home's resale value goes up too.
- Made from Recycled Material
Built from recycled wood fibers and plastic. Good for the environment and better than cutting new lumber.
- Adds Resale Value
A composite deck returns 65 to 75 percent of its cost when you sell. A beat-up wood deck does the opposite.

What Homeowners Say
Trusted Across Southern NH
Don't take our word for it. Here's what customers are saying on Google.
★★★★★
I hired Jim to update and expand an existing deck on my house. Jim was very professional and came to take a look at the existing deck he found a few structural problems that if not found could have been extremely dangerous. He was able to give me an affordable and fair quote and we proceeded with the project. Jim's work is great, his attention to detail exceeded all expectations and the final product was amazing!! He was clean and helpful with questions I had during the renovation.
★★★★★
Jim was a professional and did a great job. My wife and I are perfectionist and we couldn't be more satisfied for the work he did. This is a before and after pic. He took down our wooden deck and replaced it with composite wood and added lights on the poles. We will def be recommending him to anyone who's up for an upgraded deck. Thanks Jim.
★★★★★
I had the pleasure of hiring Jim to do a massive renovation to our back deck that we could enjoy throughout the year. The initial consultation with Jim was extremely thorough and he made sure we were comfortable with all the design choices and options that were available to us. Before we made our deposit, Jim had a highly detailed rendering of what new outdoor space would look like so we truly understood what the end result would be.

Questions We Hear All the Time
Straight answers about composite decking, cost, and how we work.
How much does a composite deck cost in New Hampshire?
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.
What is the difference between composite and pressure-treated wood decking?
Composite decking lasts longer, needs zero maintenance, and will not rot, warp, or splinter. It is made from wood fibers and recycled plastic. Pressure-treated wood is cheaper upfront but needs staining and sealing every one to two years and breaks down faster in NH weather. Once you factor in upkeep costs, composite usually comes out ahead after 10 to 15 years.
How long does composite decking last in New Hampshire?
25 to 50 years depending on the brand. Eva Last, Deckorators, and Wear Decking all carry manufacturer warranties 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.
Do I need a permit to build a deck in New Hampshire?
Yes, most NH towns require a permit for any deck attached to the house or more than 30 inches off the ground. We handle all permitting for you. We pull the permits, submit the drawings, and make sure everything meets local building code. Requirements vary by town but you do not have to deal with the town office.
What composite deck brands do you install?
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.
How long does it take to build a composite deck?
1 to 3 weeks on site for most builds once the permit is approved. From your first call to the day we start, plan for 2 to 6 weeks total 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.
What areas of southern New Hampshire do you serve?
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.
