Your local windows & doors contractor in Nashua
Waterfront Construction has been building and remodelling for Nashua and the rest of Southern New Hampshire since 2018. We are licensed, insured, and deliberately small: enough crew to keep a schedule, few enough jobs at once that your windows & doors project never becomes the one that gets squeezed.
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 windows & doors crews reach Nashua quickly from nearby Northborough. It is about 40 miles from our Northborough shop — about an hour in normal traffic.
If you may sell within a few years, what you choose matters as much as what you spend. We're straight with Nashua homeowners about which parts of a windows & doors project tend to return at resale in Southern New Hampshire and which are purely for your own enjoyment. Both are good reasons to build.
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 Nashua, rather than a number that stops answering.
For the full detail on how we approach this work — materials, process and what to expect — see our windows & doors page.

Do I need a permit for windows & doors in Nashua, NH?+
It depends on your town. New Hampshire has no statewide residential enforcement — each municipality sets and enforces its own permit rules under RSA 155-A. We confirm the requirement with your building department before we start, then file whatever it asks for. We file it with Nashua's building and inspectional services department as a Registered Home Improvement Contractor (MA HIC #196540).
Do new windows really save energy?+
Absolutely. Modern double- or triple-pane windows with low-E coatings dramatically cut heat loss in winter and heat gain in summer, lowering your bills and eliminating cold drafts.
How long does a window replacement take?+
Most window replacements are completed in 1–3 days depending on the number of openings. We protect your home and clean up fully when we're done.

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 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.
