Home Addition Contractor in Greater Boston
Room additions, second-story additions, and master suite bump-outs — Schlickmann manages the structural, mechanical, and finish work under a single contract.
Adding square footage to a Greater Boston home is often more financially sound than moving — especially in a market where transaction costs, closing fees, and the delta to a larger home can exceed $150,000. A well-designed addition adds livable space, improves function, and increases appraised value. Schlickmann handles the complete addition scope from foundation work through finished interior.
Home additions in Massachusetts require careful structural coordination. Our process begins with a feasibility assessment: we evaluate setback requirements with your municipality, review lot coverage limits, and engage a structural engineer for foundation design and beam specifications. This pre-construction phase prevents the costly surprises that derail projects managed by contractors who skip the engineering step.
The most common addition types we build in Greater Boston: first-floor room additions (family room, bedroom, home office) extending off the rear or side of the home; second-story additions over existing living space; and master suite additions incorporating a bathroom, walk-in closet, and sometimes a deck or balcony. Each type has distinct structural and mechanical requirements — we've built all of them.
Matching the addition to the existing home is where general contractor expertise matters most. Roofline integration, siding matching, window style consistency, and interior trim continuity are the details that separate an addition that looks like it was always there from one that clearly wasn't. Our carpenters take pride in this work — it's visible in every project in our portfolio.
Home Additions — FAQ
How much does a home addition cost in Massachusetts?
Home additions in Massachusetts typically range from $120,000 for a single-room first-floor addition to $350,000+ for a full second-story addition over the existing footprint. Master suite additions with bathroom, closet, and deck access typically run $150,000–$250,000. Schlickmann provides fixed-price proposals covering all permits, structural engineering, and finish work.
Do I need a permit for a home addition in Massachusetts?
Yes — all home additions in Massachusetts require a building permit, and typically electrical and plumbing permits as well. Schlickmann handles all permit applications with your local building department. Permit fees are included in our fixed-price proposals. Most Greater Boston municipalities process addition permits in 4–8 weeks.
Can Schlickmann add a second story to my home?
Yes. Second-story additions are among our more complex projects — they require careful structural assessment of the existing first-floor walls and foundation, engineer-stamped framing plans, and precise exterior matching. We've built second-story additions over 1950s Capes in Reading, Ranches in Burlington, and split-levels in Woburn. The result looks like the home was built that way.
How long does a home addition take to build?
Most home additions take 12–20 weeks from permit issuance to completion. A single-room first-floor addition typically runs 12–14 weeks. A second-story addition runs 16–20 weeks. Timeline includes foundation, framing, mechanical rough-in, insulation, drywall, and all finish work. We build a project schedule before breaking ground.
