Your local windows & doors contractor in Londonderry
Good windows & doors in Londonderry is mostly invisible: the preparation underneath, the flashing you never see, the measurement taken twice. Waterfront Construction builds that way because the owner signs off on every job personally — and because a callback costs us far more than doing it right the first time.
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.
We treat your Londonderry home the way we'd want our own treated: clean job sites, clear daily communication, and respect for your time and property. When the windows & doors project wraps, the only thing we leave behind is work you'll be proud to show off.
We stand behind what we build. If something isn't right after we've gone, you call and we come back — that's the point of being licensed, insured and easy to find in Londonderry, rather than a number that stops answering.

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 windows & doors 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.
