Alliance Deck Builders of Concord creates tailored outdoor living solutions built to handle Central New Hampshire’s mix of seasons. From icy winters to humid summers, we use the right materials and methods for long-term durability. Whether you’re near Penacook or closer to downtown, our decks are built to fit your space—and last for years.

How Can We Help?
Concord homes come in all styles—from new construction to historic colonials. That’s why every deck we build is custom-fit to your layout, lifestyle, and local zoning. We’ll help you navigate HOA rules, city permits, and material choices that work well in our region’s changing conditions.

Cedar, composite, or pressure-treated builds
Designed for snow, ice, and water runoff

Central NH decks face snow, heat, and high humidity. We build to IRC standards with frost-rated footings, galvanized hardware, and low-maintenance surfaces that won’t warp or rot. Our Concord crews work year-round when conditions allow, keeping timelines efficient without sacrificing build quality.

We go beyond basic decks. Whether you want a fully screened-in porch for bug-free evenings or an outdoor kitchen for weekend grilling, we offer custom upgrades that extend your home’s functionality. Each feature is tailored to your layout and your daily life—no prefab shortcuts.
Tight lots, older framing, and historic overlays don’t scare us. In Concord’s South End and other older neighborhoods, we design decks that respect your home’s aesthetic while meeting modern safety standards. Whether it’s a narrow side-yard build or a rooftop lounge, we get it done.


Penacook: Larger yards allow for multi-zone builds with covered grilling areas and seating nooks—perfect for families who entertain.

South End: Historic homes require low-profile decks with traditional railings—our designs meet code while matching existing architecture.

Heights: Elevated decks are common here due to slope—our crews build strong supports, safe stairs, and non-slip surfacing for safety year-round.
Don't worry, we can help!
Our Concord-based crews bring decades of experience to every job site. We’re licensed, insured, and known for clean builds, honest timelines, and high-grade craftsmanship.

We handle permitting, site prep, and construction without outsourcing, so you get consistent quality from start to finish.
From rooftop lounges to ground-level patios, we build commercial decks that make the most of your property.

We handle stamped plans, railing specs, and permits—so you don’t have to.
Planning a new deck raises good questions—especially when it comes to timing, materials, and local permits. Here are some answers from our Concord team.
Yes. We take care of the permitting process and ensure full compliance with Concord’s zoning, height, and safety codes.
Composite. It resists moisture, fading, and warping—ideal for Concord’s changing seasons.
