Your local additions & remodeling contractor in Merrimack
If you have been putting off additions & remodeling in Merrimack because you dread the process, that is usually a communication problem rather than a construction one. We give Merrimack homeowners an itemised estimate, a start date we can hold, and one person to call — then we keep to it.
Merrimack is in Hillsborough County, New Hampshire, established in 1746 and home to roughly 26,500 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. 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.
Homes around Merrimack range from classic New England colonials and capes to newer construction, and each one calls for a slightly different approach. We tailor every additions & remodeling project to the age, style and condition of your home — never a one-size-fits-all template — so the finished work looks like it was always meant to be there.
From permits and materials to the final finish and clean-up, you work directly with the owner from start to finish — one accountable point of contact for your whole additions & remodeling project in Merrimack.
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 Merrimack, the filing goes to Merrimack'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 Merrimack's office before any work starts.
