Building a deck is one of the best ways to add outdoor living space and value to your home. In New Hampshire, decks are especially popular because they provide a great spot for enjoying the short summers and mild fall evenings. However, before starting a project, most homeowners have one big question — how much does it cost to build a deck in NH?
The answer depends on several factors such as the size, materials, design, and labor involved. Let’s break down what influences deck construction costs so you can plan your project wisely.
1. Average Deck Building Costs in New Hampshire
In New Hampshire, the average cost to build a deck ranges from $4,000 to $20,000, depending on the type of materials and size. On average, homeowners spend around $25 to $45 per square foot for a professionally built deck.
For a small 10×10 deck, you might spend between $3,500 and $6,000, while a larger 16×20 deck can cost $10,000 to $18,000 or more. If you add premium materials, built-in seating, or railings, the total may increase.
2. Factors That Affect the Cost
Several elements play a role in how much you’ll pay for deck construction in New Hampshire:
-
Material Type: Pressure-treated wood is the most affordable, while composite and PVC materials are more expensive but require less maintenance.
-
Deck Size: Naturally, larger decks cost more to build due to additional materials and labor.
-
Design Complexity: Multi-level decks, curved railings, or built-in benches will raise the total cost.
-
Labor Rates: Labor prices in NH generally range from $40 to $60 per hour, depending on the contractor’s experience and location.
-
Permits and Site Preparation: Some towns in NH require building permits, which can add $100 to $500. If your yard needs leveling or special foundation work, this adds to the total price.

3. Material Options and Price Breakdown
Choosing the right material will make a big difference in both appearance and cost. Here’s what most homeowners in New Hampshire choose:
-
Pressure-Treated Wood: The most common option, costing around $15 to $25 per square foot. It’s durable but needs regular sealing.
-
Cedar or Redwood: More visually appealing and naturally resistant to decay. Expect $25 to $35 per square foot.
-
Composite Decking: Low-maintenance and long-lasting, usually priced between $35 and $55 per square foot.
-
PVC Decking: Premium option resistant to rot, mold, and moisture, costing $45 to $60 per square foot.
When selecting materials, it’s best to consider long-term value rather than only the initial cost. Composite and PVC decks last much longer with less upkeep, saving time and money over the years.
4. Hidden Costs to Keep in Mind
Apart from materials and labor, there are some hidden expenses that can affect your total deck cost:
-
Demolition of old deck (if replacing one) – around $300 to $1,000
-
Railings and stairs – $20 to $40 per linear foot
-
Lighting and electrical work – $150 to $500
-
Staining or sealing – $200 to $600 depending on deck size
Keeping these in mind helps you avoid surprises once construction begins.

5. DIY vs. Professional Deck Building
Some homeowners consider building a deck themselves to save money. A DIY deck may cost around $10 to $20 per square foot, mainly depending on materials. However, this option requires tools, time, and skill. Mistakes can lead to costly repairs later.
Professional builders not only ensure the structure meets local codes but also guarantee long-lasting results. For most people, hiring a licensed contractor is a better investment in safety and quality.
6. Tips to Save Money on Deck Construction
If you’re planning to build a deck on a budget, here are some tips that can help:
-
Choose a simple design: Avoid curves and multi-levels if cost is a concern.
-
Use pressure-treated wood: It’s budget-friendly and readily available in NH.
-
Plan during off-season: Contractors may offer discounts in late fall or early spring.
-
Maintain regularly: Cleaning and sealing every few years can extend the life of your deck.
These small choices can make a big difference in total expenses without compromising the final look.
7. Average Cost by Deck Size
| Deck Size (feet) | Average Cost Range |
|---|---|
| 10×10 | $3,500 – $6,000 |
| 12×16 | $6,000 – $9,000 |
| 16×20 | $10,000 – $18,000 |
| 20×20 | $14,000 – $22,000 |
Keep in mind these are general estimates. The actual price can vary depending on your local area, the complexity of design, and labor availability.
8. Maintenance and Long-Term Value
A deck isn’t just an addition; it’s an investment in your home’s outdoor comfort. Regular cleaning, inspection, and sealing (if it’s a wood deck) will help prevent damage and extend its life. Composite decks, while more expensive upfront, often prove to be more economical in the long run because they need minimal care and can last over 25 years.
