Home Addition Contractors in Glastonbury, CT

Every addition we build starts with a question about daily life. Maybe the kitchen needs room for a real table, the kids need their own bedrooms, or a parent is moving in and needs a suite on the first floor. Once we know what the space is for, we can work out where it goes, how big it needs to be, and how it connects to the rest of the house.

From there, the work follows a set order. We pour the foundation, frame the walls and floor, and tie the new roof into the existing one so the joint stays tight through winter. Windows and insulation come before the interior, and electrical and plumbing are coordinated with the framing instead of added at the end. Keeping one team on every phase is how affordable home additions stay realistic: fewer handoffs, fewer surprises, and a clear scope you approve up front.
