What to Know Before Building a Deck in Coastal Maine (or Southeast NH)
Straight Talk From a Builder Who’s Seen It All
So you’re thinking about building a deck—maybe a spot to grill, entertain, or just sit outside with a cup of coffee on a quiet morning. That’s a great idea.
But before you start measuring lumber or calling around for quotes, let me walk you through what you really need to know first. As someone who’s been building decks in Southern Maine and Southeast New Hampshire for nearly two decades, I’ve seen how good planning leads to great outcomes—and how bad planning leads to sagging, splitting, or permits that never clear.
Here’s what to consider before you start that deck project.

1. Deck Size and Use: What’s the Mission?
Every good build starts with a mission. Ask yourself:
• Is this deck for dining or just relaxing?
• How many people do you need to fit comfortably?
• Will this be uncovered, partially covered, or screened-in?
• Is this the primary entrance or just a backyard hangout?
Size matters—not just for space, but for permits, posts, and budget. Bigger decks require more support, stricter code compliance, and higher materials cost. That’s not a problem—but it needs to be planned for.

2. Permits Are Not Optional (Even for a “Small” Deck)
Here’s the deal:
In New Hampshire and Maine, almost every deck project requires a permit—especially if the deck is more than 30 inches off the ground or attached to the home.
And trust me: if you skip this step, town inspectors will find it. It could cost you fines, forced removal, or delays when you go to sell your home.
At Veterans Builders, we handle all permitting. We’ve worked with town offices in York, Kittery, Berwick, Portsmouth, Dover, and more. We know what paperwork they want—and how to get it passed.

3. Materials: Composite vs. Pressure-Treated
There’s no one-size-fits-all answer here. It depends on your priorities.
Pressure-Treated Wood
• Lower cost upfront
• Classic wood look
• Needs sealing and upkeep every 1–2 years
• May warp or crack over time if not maintained
Composite Decking (like Trex or TimberTech)
• Higher cost upfront
• Very low maintenance
• No splinters, rot, or resealing
• Holds color and shape for 20+ years
If you want something that looks great without constant upkeep, composite is the way to go. If you’re handy and want to save money, pressure-treated is still a solid option—we just build it right and give you maintenance tips to make it last.
4. Foundations and Framing Matter More Than You Think
What you see—the decking, the rails, the stairs—is only half the story. A strong deck starts with posts, footings, and framing that won’t shift with the first frost or downpour.
We pour footings below frost depth and use proper hardware for code-compliant framing. No shortcuts. No DIY YouTube solutions. Just clean, solid work that holds up to a New England winter.

5. Budget Range: What Does a Deck Actually Cost?
Here’s a ballpark breakdown based on what we build in the region:
• Basic 12x12 pressure-treated deck: $10,000–$15,000
• Mid-size 16x20 composite deck with rails: $18,000–$28,000
• Wraparound or multi-level decks, screened-in porches, or custom features: $30,000+
Your price will depend on size, height, material, design, and local requirements. We’ll walk your yard, take measurements, and give you a straight number—no runaround.

Frequently Asked Questions
Q: How long does it take to build a deck?
Most decks take 1–3 weeks depending on size, weather, and material availability.
Q: Can you build decks year-round?
Yes—but spring through fall is ideal. Winter builds are possible with planning, but frost and ground conditions can affect digging and concrete curing.
Q: What kind of maintenance does a deck need?
Wood decks need annual sealing or staining. Composite decks just need seasonal cleaning with soap and water.
Q: Do you do custom designs?
Absolutely. We build around your yard, your view, and your lifestyle—not a box from a catalog.
