Your local additions & remodeling contractor in Nashua
Hiring anyone for additions & remodeling in Nashua comes down to one question: will they finish what they started, the way they said they would? Waterfront Construction is a Massachusetts Registered Home Improvement Contractor (HIC #196540), fully insured, and small enough that the owner is on your job rather than running six others across the state.
Nashua is in Hillsborough County, New Hampshire, established in 1746 and home to roughly 91,500 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. We know the town well — from French Hill, downtown Nashua and the North End to the quieter streets — and our additions & remodeling crews reach Nashua quickly from nearby Northborough. It is about 40 miles from our Northborough shop — about an hour in normal traffic.
Every Nashua project starts with listening. We walk the space with you, understand how you actually live in your home, and give you straight answers about what's possible, what it will cost and how long it will take — before any work begins.
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 Nashua before we ask for the final payment.
For the full detail on how we approach this work — materials, process and what to expect — see our additions & remodeling page.

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 City of Nashua, the filing goes to Nashua's building and inspectional services 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 Nashua's office before any work starts.
