Deck Builder in Framingham, MA

In most cases, yes. Under the Massachusetts State Building Code, 780 CMR, a deck that is attached to the house or whose surface sits more than 30 inches above the ground requires a building permit from the town, and replacing an existing deck is treated as new work. A small freestanding deck that is low to the ground may be exempt, though zoning rules can still apply. The application typically includes a site plan and structural drawings, and when a contractor performs the work the town asks for the name of a licensed construction supervisor. Ask any deck builder how the permit will be handled before work begins.

Look at the structure first and the surface second. If the boards are solid, the railings are firm, and the ledger, posts and footings show no rot or movement, the deck usually needs refinishing rather than replacement: a prep cleaning, sanding, and a fresh coat of stain and sealer. A few gray or cracked boards can be swapped individually. Replacement becomes the honest recommendation when the framing is rotted, the fasteners are corroded, or the deck was built without proper footings or a flashed ledger. Stain is the standard choice for deck boards because it penetrates and wears rather than peels; paint is usually limited to railings and trim.

Because pressure-treated lumber leaves the mill saturated with the preservative solution, and stain cannot penetrate wood that is still holding that moisture. Applied too early, it sits on the surface, dries unevenly and peels within a season. The trade practice is to let the boards dry until water sprinkled on them soaks in instead of beading up, which in New England can take anywhere from several weeks to a few months depending on sun, airflow and the time of year the deck was built. Kiln-dried treated lumber is the exception and can be finished sooner. The water test, not the calendar, decides when the deck is ready.

For a one- or two-family home, the Massachusetts State Building Code requires a guard, the railing that keeps people from falling off the edge, on any deck whose walking surface is more than 30 inches above the ground. That guard must be at least 36 inches high, measured from the deck surface, and its balusters must be spaced so that a 4-inch sphere cannot pass through. Deck stairs generally need a graspable handrail as well. Older decks across MetroWest were often built with lower or wider railings, so a railing that looks fine may still fall short of code, which matters when a home is sold or inspected.
