| Service | Price | Details |
|---|---|---|
| Wood Rot & Dry Rot Repair | From $650 | Coastal moisture and hard winters make wood rot a fact of life in Boston. The city's triple-deckers and Victorian rowhouses suffer worst. We cut out decayed framing, siding and trim, treat the surrounding wood, and rebuild with rot-resistant lumber. That is a permanent repair, not a cosmetic patch. |
| Termite Damage Repair | From $1,200 | Boston's humid summers bring real termite pressure to the region's older homes. After the exterminator leaves, the damaged wood stays. We replace termite-eaten studs, sills, trim and subfloor sections, working from your pest inspection report and restoring full structural integrity. |
| Floor Joist & Subfloor Repair | From $1,800 | Sagging, bouncy or soft floors are common in Boston's older housing stock. In triple-deckers and rowhouses the cause is usually damaged joists or subfloor, or foundations shifting with the region's severe freeze-thaw cycle. We sister or replace compromised joists and rebuild subfloor sections, leveling floors before finishes go back down. |
| Beam Replacement & Load-Bearing Wall Removal | From $3,500 | Open-concept conversions and failing beams call for real structural carpentry. In Boston's triple-deckers and rowhouses that usually means a new beam where a wall used to be. We install engineered beams, replace sagging headers and remove load-bearing walls, always built to the engineer's specs and the permit requirements of your local building department. |
| Framing & Structural Carpentry | From $2,500 | Remodel framing done right, straight and plumb in century-old Boston homes. New interior walls, garage and basement build-outs, wall openings, and repairs to storm- or water-damaged framing. The bones your finish work deserves. |
| Finish & Trim Carpentry | From $550 | The details that separate a real finish carpenter from a handyman. Tight miters, scribed fits, consistent reveals. Casing, paneling, wainscoting and custom trim work throughout Boston homes, old and new. |
| Crown Molding & Baseboard Installation | From $450 | Crown molding and baseboards fitted to the period rooms of Boston homes. We cut coped joints and clean caulk lines for Back Bay and Beacon Hill interiors, matching existing profiles or keeping them crisp and modern. Chair rail and window trim as well. |
| Custom Built-Ins & Shelving | From $1,900 | Built-ins designed for Boston's triple-deckers and Victorian rowhouses. Bookshelves, window seats, media walls, closet systems and Murphy beds, custom-fitted to bay windows, sloped ceilings and every awkward alcove. |
| Interior Door Installation & Repair | From $350 | Doors that stick or never latched right are common in old Boston homes. Foundations shift with the region's severe freeze-thaw cycle and frames go out of true. We hang, adjust and replace interior doors, repair jambs and frames, and install pocket and barn doors. |
| Exterior & Entry Door Installation | From $850 | Entry, back and French doors installed weather-tight against nor'easters. Boston Harbor's coastal moisture finds every gap, so units are properly flashed, insulated and secured. We repair rotted door frames and thresholds, or replace the full unit. |
| Cabinet & Vanity Installation | From $1,100 | Kitchen cabinets and vanities set level on Boston's out-of-level floors. Older homes rarely give you a square wall, so runs are scribed to fit, with hardware aligned and doors adjusted. Laundry storage as well. |
| Stair & Railing Repair | From $600 | Squeaky treads and loose banisters on stairs that are climbed every day. We repair and rebuild the staircases of Boston's triple-deckers and rowhouses, restore period railings, and install code-compliant handrails and attic ladders. |
| Deck & Porch Repair | From $900 | Nor'easters, snow load and coastal humidity are hard on Boston decks. The region's iconic triple-decker porches take the same beating. We replace rotted boards, posts and railings, repair stairs and structural framing, and get outdoor spaces safe before winter. Repair first, and honest about when replacement wins. |
| Fascia, Soffit & Exterior Trim Repair | From $700 | Peeling paint and soft fascia are the first sign of ice-dam moisture. After a heavy Boston winter it works in behind the roofline. We replace fascia, soffits and exterior trim with primed, rot-resistant material, closing the gaps that let moisture and pests into the roofline. |
