Your local additions & remodeling contractor in Chelsea
Waterfront Construction provides professional additions & remodeling for homeowners throughout Chelsea and nearby towns. From our base in Northborough we keep response times short and standards high — fully licensed and insured, owner-supervised on every job, and committed to leaving your Chelsea home better than we found it.
Chelsea is in Suffolk County, Massachusetts, established in 1739 and home to roughly 41,000 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 large community, so the housing runs the full range of eras and budgets. It sits in Greater Boston. It is about 40 miles from our Northborough shop — about 45 minutes to an hour in normal traffic. Being close keeps estimates and site visits quick.
Material choice drives most of the cost difference on a additions & remodeling project. Rather than quote one option, we walk Chelsea homeowners through what each tier actually buys in durability, upkeep and appearance — so the budget goes where it matters to you, not where it matters to us.
No surprises and no runaround: you get an itemized estimate up front, a realistic schedule, and honest updates if anything changes. That's how we've earned repeat business and referrals across Chelsea and the wider region.

An addition always needs a permit, and usually more than one.
780 CMR only exempts minor finish work and small detached structures. Anything that changes the footprint, cuts into a load-bearing wall, alters a means of egress or touches the mechanical systems requires a building permit — typically alongside electrical, plumbing and gas permits. As your licensed contractor we file all of them and book the inspections.
For additions & remodeling work in the City of Chelsea, the filing goes to Chelsea's building and inspectional services department.
