TH Finish Carpentry

TH Finish Carpentry is a small carpentry crew based at 2 Putnam St in Nashua, New Hampshire, run by an owner named Thales who is named personally in almost every review the business has collected. Homeowners hire the team for finish and trim work first — Azek trim around windows and doors, staircases, interior carpentry — and then call it back for bigger jobs. The reviews on file run from May 2024 to July 2026 and describe distinct, checkable projects rather than generic praise. One homeowner had an upper deck replaced and, when demolition showed both deck structures were compromised, had the whole thing rebuilt with proper posts, flashing to keep rain off the house cladding and composite boards. Another had a leaking tiled shower floor and the structure beneath it replaced, the ceiling below repaired, and a garage storage staircase rebuilt. A third watched the crew swap a neighbour's window trim from wood to Azek on a Boston-area house, liked the result and hired them for their own doors and windows. The praise is as consistent about how the crew works as about what it builds: arriving when they said they would, putting in full days, cleaning up, and staying polite around a family and its property. Several reviewers raise price directly — one says the deck quote came in better than the general contractors they had contacted, others call the rates reasonable across a wide range of work. Repeat customers show up more than once, including one who used the team at two different houses, and one review is written in Portuguese. Two things are worth raising before booking. Scope can move: that deck job grew from a partial replacement to a full rebuild once demolition exposed the structure, so agree up front how change orders and pricing are handled if a demo turns up more than expected. And the written record is narrow — thirteen ratings, all on one Google profile, all five stars — so ask for references on a job the size of yours and photos of comparable work. New Hampshire does not register home-improvement or general contractors, so there is no state carpentry registration to check here; if your project includes plumbing, gas or electrical work, those trades are licensed through the state's Office of Professional Licensure and Certification and should be handled by a licensed tradesperson. TH Finish Carpentry looks like the right call for trim, decks, stairs and bathroom carpentry around Nashua and across the Massachusetts line, particularly for homeowners who value a crew that shows up on schedule and leaves the site clean. Confirm insurance, a written scope and change-order terms before work starts.
