Frequently Asked Questions
How long does it take to build a deck?
A standard backyard deck typically takes 1 to 2 weeks from footings to final walkthrough. Larger multi-level builds run longer. We give you an exact timeline in your free estimate.
Do I need a permit for my deck in New Hampshire?
Most New Hampshire towns require a building permit for decks above a certain height or square footage. We handle the permit conversation and pull what your town requires.
Composite or pressure-treated wood?
Both work. Composite costs more upfront but needs almost no maintenance. Pressure-treated costs less and looks great if you re-stain every 2-3 years. We help you choose based on your budget and how you want to use the deck.
