Duffy Development LLC

Duffy Development LLC is a Needham-based general contractor and carpentry outfit run by Ian Duffy, holding an active Massachusetts home improvement contractor registration the state has verified (license #196191). Its Houzz profile describes work spanning custom home construction, additions, and remodeling across roughly 20 towns west of Boston, and BuildZoom's profile lists six permitted projects through the company. Across five different platforms, the one constant is the string of five-star reviews — eleven in all, dated 2020 through 2025, several from clients who came back for more than one project. In a 2025 Google review, a homeowner singled out the attention to detail on a kitchen remodel and how clear and responsive the team stayed throughout; a 2024 reviewer said they had worked with Ian for more than five years across multiple jobs. The scope of that work runs a wide range: a 2020 BuildZoom review describes a full house renovation costing about $252,000, with Ian credited for keeping several phases on schedule and on budget, while a separate 2020 Houzz review describes a deck and basement redo at what the client called reasonable pricing. Another 2020 BuildZoom review covers a kitchen redo bundled with painting the whole house, new carpet, and a roof fix, and a 2021 Google review praises a renovation that also added HVAC. A 2022 Houzz review, describing years of carpentry, insulation, and painting work on an older Victorian home, calls the crew responsive and skilled. Both Houzz and BuildZoom list the same Massachusetts license number the state registry independently verifies as active, and Houzz has also given the company a badge and an award. Given how much project size varies here — from a basement redo to a quarter-million-dollar whole-house renovation — it's worth pinning down early where a given job is likely to land on that range before getting a quote. Duffy Development reads like the right call for homeowners west of Boston tackling a real renovation or addition rather than a single quick fix — the reviews consistently describe multi-trade projects, kitchens, additions, decks, basements, handled by one team from planning through completion.
