Custom deck and porch construction for homes in Charlestown, New Hampshire.
You step out your back door onto grass or gravel when you should have a level surface that connects your home to the yard. A properly built deck or porch gives you a place to set furniture, grill without moving across uneven ground, or sit outside without tracking mud indoors. If your home in Charlestown lacks usable outdoor space or your existing deck shows rot, sagging joists, or loose railings, you are dealing with either a missing feature or a failing structure that needs replacement.
T2B Carpentry, LLC builds decks, front porches, covered porches, and accessory structures that attach to your home or stand independently. The process includes designing the layout to match how you plan to use the space, pulling permits, setting footings below frost line, and framing with materials suited to New Hampshire weather. You choose between pressure-treated lumber, composite decking, or cedar based on maintenance preferences and budget.

Build the Outdoor Space You Actually Use
How the Structure Gets Built and Finished
Construction in Charlestown begins with marking footing locations, digging to frost depth, and pouring concrete piers that support the posts. T2B Carpentry, LLC frames the deck or porch with joists spaced to code, installs blocking for stability, and attaches the ledger board to your home with flashing that prevents water from reaching the siding. Decking goes down with proper spacing for drainage, and railings get installed at the height required by local code.
Once the structure is complete, you will have a level surface that does not shift or bounce when you walk across it. Railings feel solid when you grip them, and the deck sheds water instead of trapping it against the joists. If you chose composite decking, the surface resists splintering and does not require annual staining.
The work includes excavation, footings, framing, decking, railings, and stairs if the elevation requires them. It does not include electrical for lighting or plumbing for outdoor kitchens unless specified during planning. If you want a roof over the porch or a pergola attached to the deck, those elements get priced separately and built after the main structure passes inspection.
What material lasts longest in New Hampshire weather?
Composite decking resists moisture and insect damage better than wood and does not require staining, but pressure-treated lumber costs less upfront and performs well if maintained every few years. Cedar offers a middle option with natural rot resistance and a cleaner appearance.
How deep do footings need to go?
Footings in Charlestown must extend at least four feet below grade to sit below the frost line. This prevents the structure from shifting during freeze-thaw cycles that happen throughout winter and early spring.
When do I need a permit for a deck?
Most decks in New Hampshire require a building permit, especially if they attach to the home or stand more than thirty inches above grade. T2B Carpentry, LLC handles the permit application and schedules inspections as part of the project.
How long does it take to build a deck?
A typical deck takes one to two weeks from excavation to final inspection, depending on size, complexity, and weather. Covered porches take longer because they involve roofing and additional framing for posts and beams.
What happens if the ground slopes away from the house?
T2B Carpentry, LLC adjusts footing depths and post heights to create a level deck surface regardless of slope. Stairs or a stepped design can connect the deck to grade if the elevation difference is significant.
T2B Carpentry, LLC builds decks and porches for homes throughout Charlestown, and every project starts with a site visit to confirm measurements, drainage, and access.

Questions That Come Up During Planning
Homeowners in Charlestown usually ask about material longevity, permitting timelines, and whether a deck can be built onto an existing foundation. These questions shape the project scope and help you understand what gets included in the build versus what requires additional planning.
