Somerville, MA Carpentry Services
Somerville is one of the most densely built cities in New England, with two-families and triple-deckers packed onto small lots around Davis, Union, Ball and Teele Squares and up the slopes of Winter Hill, Spring Hill and Prospect Hill. Many have been converted to condos. CB Carpentry provides rough carpentry, finish trim, cabinetry and built-ins, exterior carpentry, doors and windows and flooring for Somerville homeowners and condo owners. We are comfortable working on tight lots and narrow streets and plan deliveries and parking so the job runs smoothly.
What we build in Somerville
Rough Carpentry
Somerville homes are mostly older wood-frame buildings, and renovations frequently uncover tired joists, rotted sills and porch framing that needs replacement. We install beams, sister joists, frame new layouts in condo conversions and renovations and replace rotted framing. Permits from the city are required for structural work, and we plan around inspections.
Attic and basement conversions are common in Somerville as owners look for more space, and both need new framing, stairs and ceilings that fit into an older building. We plan the work with your designer and the city so inspections go smoothly. Work areas are sealed to limit dust for neighbors.
Rough Carpentry detailsFinish Carpentry
We install crown, baseboards, wainscoting, panel molding and casing, match original trim in older homes, and rebuild stairs and railings in shared stairways and private units. Accent walls with panel molding, like the one in our photos, add character to condo living rooms and bedrooms.
Many Somerville units lost their original trim in past renovations. We can put back character with taller baseboards, wider casings, crown molding and wainscoting, or match the original profiles that remain elsewhere in the building. Shared stairways get new treads, tightened railings and balusters spaced to code. All trim is primed and ready for your painter.
Finish Carpentry detailsCabinetry & Storage
Small Somerville kitchens and bedrooms need smart storage. We install kitchen and bath cabinets, build built-in bookshelves, window seats and wardrobes, and add storage under stairs and in eaves. Built-ins can give a room without a closet the storage it needs.
Kitchens in two-family and triple-decker units are often narrow, so cabinet layouts and installation have to be precise. We set cabinets level on floors that slope and scribe fillers to uneven walls. In bedrooms without closets, built-in wardrobes give real storage without taking much floor space. Window seats with drawers add storage in small living rooms without using closet space.
Cabinetry & Storage detailsExterior Carpentry
Front and back porches define Somerville's triple-deckers and two-families. We rebuild porch framing, decking, stairs and railings to code, replace rotted trim, soffits and fascia, and build fences and small decks for tight backyards.
Stacked rear porches on Somerville triple-deckers are often the second way out of each unit, so they have to be built solidly. We rebuild posts, beams, joists, decking, stairs and railings, and use pressure-treated framing and corrosion-resistant hardware. We also replace rotted trim, soffits and fascia before water reaches the framing behind them. On tight lots, we plan material staging and deliveries so neighbors are not blocked in.
Exterior Carpentry detailsDoors & Windows
We hang interior doors, install entry and back doors with proper flashing and secure hardware, and repair rotted window sills and jambs. Older Somerville buildings often need doors scribed to fit openings that have shifted over time.
In multi-family homes, unit entry doors and back porch doors take heavy use. We install solid doors with good locks, repair rotted thresholds and frames, and rehang interior doors that no longer close because the building has shifted. New windows get extension jambs and interior trim so they look finished inside. Exterior doors get sill pans and flashing so thresholds stay dry year-round.
Doors & Windows detailsFlooring
We install solid and engineered hardwood flooring, level old subfloors and weave new boards into original floors. Engineered hardwood is a practical choice for condo units.
Many Somerville homes have old strip oak that has been patched over the years. When new flooring goes in, we refasten and level the subfloor, replace damaged sections and install solid or engineered hardwood. Condo buildings may have rules for sound-control underlayment, which we follow. We finish thresholds and stair nosing so each unit looks complete. Stair treads and nosing are matched to new floors, and thresholds are installed where hardwood meets tile in kitchens and baths.
Flooring detailsResidential Carpentry Contractor in Somerville, MA
Most of Somerville's homes were built in a short span around the turn of the 20th century, when streetcar lines made the city a convenient place for working families to live. The result is block after block of two-families and triple-deckers on small lots, many with front and back porches. These buildings have been renovated many times, and carpentry in Somerville often means correcting past shortcuts, rebuilding porches and stairs, and adding storage in tight floor plans.
Many Somerville owners are renovating condos or the units in a two-family they live in, and every square foot counts. We help make tight floor plans more usable with built-in storage, better closets and well-planned kitchens, and we restore the trim and stair details that give older Somerville homes their character.
