Sandown is in Rockingham County, New Hampshire, established in 1756 and home to roughly 6,500 people. It was settled well before the Republic, which usually means a core of Federal and Greek Revival homes surrounded by later infill — plenty of hand-framed structure, and rooflines never meant to carry today's insulation. For a contractor that makes it a small town, which usually means a mix of older centre-of-town housing and newer subdivisions on the edges. It sits in Southern New Hampshire. It is about 60 miles from our Northborough shop — about an hour in normal traffic. Being close keeps estimates and site visits quick.
A additions & remodeling project touches several trades, and the gaps between them are where problems hide. We coordinate all of them under one contract for Sandown homeowners — one schedule, one standard, and nobody pointing at anybody else when a question comes up.
Call and you get a person, usually the owner. Message us and you get an answer within one business day. On a additions & remodeling project in Sandown that responsiveness isn't a courtesy — it's what keeps the job moving.

In New Hampshire, permit rules are set locally — not by the state.
New Hampshire’s State Building Code (RSA 155-A) adopts the 2021 IRC, but there is no statewide residential enforcement office: each municipality adopts and enforces it through its own building department. That means work exempt in one town may need a permit in the next. We confirm the requirement with your building department before we start, and we file whatever it asks for.
For additions & remodeling work in the Town of Sandown, the filing goes to Sandown's building department. As a Massachusetts Registered Home Improvement Contractor (HIC #196540) we pull the permit in our name, book the inspections and meet the inspector on site — you never have to take a day off for it. Requirements do change, so we confirm the current position with Sandown's office before any work starts.
