Interior Finishing, Flooring Installation, Drywall, Painting and Trim
Interior finishing is the difference between a renovation that looks built and one that looks crafted. Our general contractor team in Cornwall installs and repairs drywall, applies Level 5 finishes where needed, and frames non-structural walls for layout changes. We install hardwood, LVP, laminate, ceramic tile, and carpet across all room types, including stairs and transitions. See our interior renovation Cornwall services for the full scope.
Interior painting, trim carpentry, baseboards, casing, crown moulding, and built-in millwork all fall within our scope. We work to a clean finish that requires no touch-ups before you move back in. Whether it is a single room repaint or a whole-house refresh after a renovation, we leave your property ready to photograph and list.
