Londonderry is in Rockingham County, New Hampshire, established in 1722 and home to roughly 26,000 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 mid-sized town with a genuinely varied housing stock, from the oldest streets to recent construction. It sits in Southern New Hampshire. It is about 50 miles from our Northborough shop — about an hour in normal traffic. Being close keeps estimates and site visits quick.
Because we're based nearby in Northborough, getting to Londonderry is quick for us — which means faster estimates, easier site visits and a team that's genuinely responsive when you have a question. You're working with a local contractor who answers the phone, not a distant call center.
The job isn't finished when the work is. We haul away the debris, protect and clean everything we touched, and walk the whole additions & remodeling project with you in Londonderry before we ask for the final payment.

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 Londonderry, the filing goes to Londonderry'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 Londonderry's office before any work starts.
