Everlast Construction

Everlast Construction is a family-owned general contracting company based in Amherst, New Hampshire, founded in 1986 by owner Joe Serpa. The company describes itself as a major builder across Southern New Hampshire and the Boston area, taking on custom homes, additions, remodels, decks, excavation work and accessory dwelling units (ADUs). Homeowners who have hired Everlast consistently point to sound craftsmanship on deck, porch and sunroom projects. A 2022 review described a planned screened-in deck off a kitchen that turned into a well-built sunroom, praised for solid construction and craftsmanship throughout. A later review, from 2024, described a back-porch renovation where Joe Serpa visited the property twice to plan the work, two carpenters converted old screens and plastic sheeting into eight new windows, and Serpa checked on progress daily until the job wrapped up. A third review, from 2025, called the crew's recent work stellar and said they went above and beyond. Before booking, it's worth knowing how small the public review record is — just three written reviews span 2022 through 2025, all five stars, so there isn't a long history to draw patterns from beyond consistent satisfaction on the specific jobs that were reviewed. Ask about current crew size and timelines for a project your size, since the reviewed work has centered on additions to existing structures — decks, porches, window conversions — rather than the full custom-home builds the company also advertises. Everlast is a reasonable call for homeowners in the Amherst and Southern New Hampshire area looking for a small, owner-involved contractor for additions, decks, sunrooms or window-focused renovation work, where the reviewed jobs have consistently pleased customers. Confirm current licensing, insurance and a written scope before signing, and ask for references from a project similar in scale to yours.
