Carpentry & Wood Rot Repair in Boston, MA · Fully Insured Professionals

Carpenter in Boston, MA: Wood Rot, Structure & Finish Work

Boston Carpentry is a residential carpentry shop serving homeowners across Boston and the surrounding areas, including Cambridge, Somerville, Brookline, and Newton. We work on the full range of carpentry: structural repairs to rotted framing and damaged floor joists, beam replacement and load-bearing wall removal, and the finish carpentry and custom built-ins that make an old house livable. The building stock here is unlike anywhere else in the country. Victorian brownstones line Back Bay and the South End. Colonial-era wood-frame homes fill the North End and Charlestown. Triple-deckers by the thousands rise across Dorchester, Roxbury, and Jamaica Plain. Many of these homes have original framing and sills that have been fighting New England weather for well over a century, and they have settled, shifted, and absorbed the moisture that comes with nor'easters, freeze-thaw cycles, and hot humid summers.

When homeowners search for a carpenter near me in Boston, they are often calling because they have found wood rot advancing into a sill or fascia, discovered termite damage after a pest inspection, or noticed a floor that has gone soft or bouncy underfoot. We read the damage honestly, explain what caused it and what it will cost to fix, and propose repair over replacement whenever the wood justifies it. The same carpenters who diagnose the problem do the work, and we know this building stock. Call (857) 353-6607 to schedule a free wood rot inspection, or learn more about our Wood Rot & Dry Rot Repair services.

Why Wood Fails in Boston, and How We Read It

Wood fails in Boston for reasons rooted in the local climate and the age of the housing stock. Dry rot is a fungus that thrives in sustained moisture without standing water, which is exactly what New England winters and humid summers provide to wood sills, window frames, deck ledgers, and fascia boards. The freeze-thaw cycle works water into joints and grain, and the fungus colonizes the damp wood over months or years. Wet rot appears at the base of walls where water pools or where a sill plate meets the foundation. Termites and wood-boring beetles hollow a joist or beam from the inside while the painted surface still looks sound, and by the time the damage is visible, the structural section has often been substantially compromised. All three pathologies share one thing in common: they are fed by water, and if the water source is not closed, the repair fails again.

We assess rot by probing to find where sound wood begins, checking the framing behind the visible surface, and tracing the water path that fed the decay. A member with cosmetic surface rot over sound wood can be cut out and rebuilt with new material, sistered, or capped. A member that has lost its structural section must be replaced. Filler applied over active rot is not a repair. On termite and beetle damage, we work from your pest inspection report. We repair and replace the damaged wood. We do not treat, fumigate, or perform pest control, which is a separate regulated trade. The distinction matters. A homeowner who has found termite damage should have a licensed pest control professional assess the infestation and recommend treatment. We then repair the wood that was damaged. Call (857) 353-6607 to discuss what you have found, or request a free wood rot inspection to understand the scope and the cost of repair.

The honest call is this: if the water source can be closed and the sound wood is enough to rebuild, repair is the answer. If the member has lost too much section, or if the water problem cannot be solved, replacement is the answer. We quote both when both are real options, and we explain why one makes more sense than the other. A repair that does not address the water will cost you twice.

Structural Carpentry in Boston: Joists, Beams and Settling

A century-old building that has settled slowly is the normal condition in Boston. Sloping floors, sticking doors, and walls that are slightly out of plumb are the signature of a house that has been standing for a hundred years and will stand for a hundred more. What matters is not whether something has settled, but whether it is still moving, and how the structural member is doing where it bears weight. A floor joist that is sound but undersized can be sistered, running a new joist alongside the old one and tying them together. A subfloor section that has rotted or been damaged by insects gets replaced. A sill plate or rim joist that has lost its bearing can be rebuilt or reinforced. We assess each member in place, understand what it is doing, and propose the repair that will last. Floor Joist & Subfloor Repair is often the most visible structural work, but it is also some of the most straightforward: a sound repair here means a solid floor that will not move or creak for decades.

Larger structural changes, such as removing a load-bearing wall to open a room or replacing a beam, commonly require engineered drawings and a permit from the local building department. We build to those drawings and work within the permit process, but we do not produce structural engineering drawings or load calculations. A licensed structural engineer sizes the beam, calculates the loads, and produces the drawings that the building department requires. We then install the work according to those specifications. Beam Replacement & Load-Bearing Wall Removal is work we do regularly, and we understand the sequencing and the temporary support required. The engineering and the permit are separate conversations with the building department, and they are essential to getting the job right.

Finish Carpentry and Built-Ins in Boston Homes

Finish carpentry in Boston's older housing stock is about matching what is already there and respecting the constraints of a building that was not drawn on a computer. Bay windows, narrow hallways, out-of-square openings, and compact floor plans are the reality of Victorian brownstones and triple-deckers. Original millwork, casing, baseboard, crown molding, and wainscoting, was built to fit the rooms as they are, not to some perfect standard. When we install new trim or Crown Molding & Baseboard Installation, we match the profile and the reveal of what is already there. We use coped joints instead of caulked corners, we scribe to walls that are neither flat nor plumb, and we keep the reveals consistent so the eye reads the work as original. Custom Built-Ins & Shelving, Cabinet & Vanity Installation, and Interior Door Installation & Repair follow the same logic: measure carefully, fit to the space you have, and make the joint tight and invisible.

Stairs, railings, exterior doors, and deck framing are finish carpentry in the structural sense. A stair stringer that is worn or cracked can be repaired or replaced depending on what is sound. A railing that is loose gets tightened or rebuilt. An entry door that is warped or rotted gets replaced with something that matches the style and the opening. A deck frame that has rotted fascia or ledger board gets repaired or rebuilt, and the water path that caused the rot gets closed. These are the details that make a house feel solid and safe, and they are worth doing right.

Permits, Repair-or-Replace & What We Do Not Do

Permits are required for many types of structural work, though requirements vary by jurisdiction. A permit is commonly required for work such as removing or altering a load-bearing wall, replacing beams or floor joists, and modifying stairs or exterior decks. The threshold for when a permit is required, and what the permit process involves, depends on the local building department and the scope of the work. We can help you understand what is likely to need a permit and what the process will involve, but the decision and the application belong to you and the building department. Before starting any structural project, contact your local building department to verify what permits are required for your specific work.

On the question of repair versus replacement, the decision turns on a few simple facts: how much sound section is left in the member, whether the water source that caused the damage can be closed, and what the two options cost. When both are real possibilities, we quote both and explain the trade-off. We are fully insured, and we can help you document damage for an insurance claim, but the decision about whether a claim will be approved and what will be covered is between you and your insurance company. Requirements vary, and building codes and permit thresholds change. Always verify with the Boston building department before starting your project.
