Your local additions & remodeling contractor in Derry
If you're planning additions & remodeling in Derry, NH, you want a contractor who shows up, communicates, and delivers. That's exactly what Waterfront Construction has built its reputation on across Eastern Massachusetts and Southern New Hampshire since 2018 — owner-led work, fair and itemized pricing, and a finished result that holds up to New England's seasons.
Derry is in Rockingham County, New Hampshire, established in 1827 and home to roughly 34,500 people. Its growth came with the mills and the railroads, so much of the older housing is mid-1800s worker and merchant stock — balloon framing, deep sash windows, and porches that have usually been rebuilt at least once. 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.
If you may sell within a few years, what you choose matters as much as what you spend. We're straight with Derry homeowners about which parts of a additions & remodeling project tend to return at resale in Southern New Hampshire and which are purely for your own enjoyment. Both are good reasons to build.
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 Derry 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 Town of Derry, the filing goes to Derry'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 Derry's office before any work starts.
