Question 1

How do I know if I need to replace my deck or just repair it?

Accepted Answer

Replace your deck if the structural framing shows rot or damage, if more than 25% of boards need replacing, or if the deck is over 20 years old with multiple issues. Minor surface problems like a few split boards or loose railings can often be repaired. We're happy to assess your deck and give an honest recommendation during a consultation.

Question 2

What should I look for when choosing a deck builder?

Accepted Answer

Look for proper licensing and insurance, experience with your specific project type (replacement, multi-level, pool deck), willingness to handle permits, clear written contracts, and references from local projects. Avoid contractors who require large upfront deposits or pressure quick decisions.

Question 3

How much does a deck cost in New Hampshire?

Accepted Answer

A deck in New Hampshire typically costs $15,000 to $75,000 depending on size, materials, and complexity. A basic 12x16 pressure-treated wood deck starts around $15,000-$20,000. Premium composite decks with features like lighting and cable railings often exceed $50,000. Every project is different—we provide detailed quotes after understanding your specific needs.

Question 4

Is composite decking worth the extra cost over wood?

Accepted Answer

Composite is worth the extra cost if you want minimal maintenance and plan to stay in your home 10+ years. The higher upfront investment typically breaks even around year 12-15 when wood maintenance costs accumulate. If you enjoy maintaining outdoor spaces or have a tight initial budget, wood remains a valid choice.

Question 5

Do I need a permit to build a deck in NH?

Accepted Answer

Yes, most deck projects in New Hampshire require permits. Generally, any deck over 200 square feet or more than 30 inches above grade requires a building permit. Deck Pros handles all permit applications, drawings, and inspections as part of our service.

Question 6

What are the railing height requirements for decks in New England?

Accepted Answer

Residential deck railings must be at least 36 inches tall in most jurisdictions, with some requiring 42 inches. Pool barriers require a minimum of 48 inches. Stair handrails must be 34-38 inches measured from the stair nosing. Baluster spacing cannot exceed 4 inches.

Question 7

How long does it take to build a deck?

Accepted Answer

Most deck projects take 1-3 weeks from start to finish. A simple single-level deck typically completes in 5-7 working days. Large multi-level decks with custom features can take 3-4 weeks. This includes permits, construction, and final inspection.

Question 8

What is the best time of year to build a deck in New England?

Accepted Answer

Late spring through early fall (May-October) is ideal for deck construction in New England. However, we can build in colder months as long as the ground isn't frozen and conditions are safe. Planning during winter for spring construction often means better scheduling availability.

Question 9

What is the best decking material for New England weather?

Accepted Answer

Capped composite decking (like Trex Transcend or TimberTech Pro) offers the best balance of durability and low maintenance for most New England homes. For pool decks or coastal properties, 100% PVC synthetic decking provides superior moisture resistance. Learn more in our complete materials guide.

Question 10

How do I maintain a composite deck?

Accepted Answer

Composite decks require minimal maintenance—sweep debris regularly and rinse occasionally with a garden hose. Every 2-3 years, a deeper clean with a composite-safe cleaner or low-pressure wash keeps the surface looking new. No staining, sealing, or sanding is needed.

Question 11

How do I maintain a wood deck in New England?

Accepted Answer

Wood decks require consistent maintenance to perform well in our climate. Apply penetrating stain or sealer every 2-3 years, sweep debris regularly to prevent moisture trapping, and inspect annually for signs of rot, loose fasteners, or damaged boards. Pressure wash before refinishing.

Question 12

Does New England weather damage decks faster than other regions?

Accepted Answer

Yes, our combination of freeze-thaw cycles, heavy snow loads, and humidity is harder on decks than most U.S. climates. Materials that absorb water suffer most—water expands when frozen, causing checking, splitting, and accelerated decay. Proper material selection and drainage design mitigate these effects.
