Beam Replacement & Load-Bearing Wall Removal in Boston, MA · EPA Lead-Safe Certified Firm

Boston's oldest neighborhoods, from the Victorian brownstones of Back Bay and the South End to the colonial-era wood-frame homes of Charlestown and the iconic triple-deckers of Dorchester and Jamaica Plain, were built with framing designed for a different era. When you want to open up a kitchen, remove a wall to create an open floor plan, or address a beam replacement and load-bearing wall removal project, you're working with structural wood that has stood for over a century. Freeze-thaw cycles, humidity swings, and the settling that comes with age all take their toll on original beams and headers. We remove and replace failing beams, install engineered headers to carry the load, and remove load-bearing walls to spec, always working from a structural engineer's design and your local building department's permit requirements.

Why Beam Replacement and Load-Bearing Wall Removal Matters in Historic Boston Homes

Boston's housing stock is older and more densely built than most American cities. Original framing in these homes relied on solid wood beams and bearing walls that have shifted, settled, and weakened over generations. A sagging beam over a kitchen or living room isn't just cosmetic; it signals that the structure is losing its ability to carry the load above it. Removing a load-bearing wall to create open space requires that load to go somewhere else, typically onto an engineered beam that is sized and installed to handle it safely. This is structural work and commonly requires both a licensed structural engineer's design and a permit from your local building department.

• We install engineered beams (steel, engineered lumber, or solid dimension lumber) sized to the loads and spans calculated by a structural engineer.
• We remove load-bearing walls once the beam is in place and properly supported, transferring the load safely to the new structure.
• We replace sagging headers and failing beams that have lost capacity due to wood rot, settlement, or undersizing for modern use.
• We frame temporary support walls during the work to protect the structure and the occupants above while the new beam is installed and the old one is removed.
• We work to the structural engineer's specifications and your building department's permit, ensuring the work meets code and is inspected at each stage.

Structural work done right protects your home's integrity and your family's safety for decades to come.

Key info: In Boston's triple-deckers and older frame houses, sagging floors and cracked plaster ceilings often point to a failing beam or settling foundation. A structural engineer can assess whether repair, sistering, or full replacement is the right move. We handle the carpentry; the engineer handles the design. Boston's Inspectional Services Department oversees permits for structural alterations.

How We Handle Beam Replacement and Load-Bearing Wall Removal in Boston

Structural carpentry requires planning, sequencing, and precision. We start with your structural engineer's design (or help you understand why you need one), then work with your local building department to secure the necessary permits. The work itself follows a careful sequence to keep your home safe and the structure stable throughout the process.

1. We schedule a site visit to review the engineer's plans, assess the existing structure, and plan how we'll support the load during the work.
2. We frame temporary support walls (called shores) to carry the load above while we remove the old beam or wall and install the new one.
3. We install the new engineered beam on permanent support posts or bearing walls, ensuring it sits on solid bearing and is properly fastened.
4. We remove the old beam or wall once the new structure is in place and the load has safely transferred.
5. We remove the temporary support and finish the framing, casing, and any trim that was affected by the work.
6. We coordinate with your local building inspector for sign-offs at framing, beam installation, and final completion.

The whole process, from shoring to final trim, typically takes one to three weeks depending on the complexity of the job and whether the work is visible or hidden in the walls.

Local example: A Somerville Victorian needed its first-floor wall removed to open the kitchen to the living room. A structural engineer designed a steel beam to carry the second-floor load. We built temporary shores, removed the wall stud by stud, installed the beam on new support posts, and finished the ceiling and sides with new drywall and trim. The work took two weeks and required two building inspections. See our framing and structural carpentry page for more on how we approach these projects.

Beam Replacement and Load-Bearing Wall Removal Methods

The right method depends on the span, the load above, the available space, and whether the goal is repair or removal. A structural engineer's assessment determines which approach makes sense for your specific situation.

Beam Replacement and Load-Bearing Wall Removal Cost in Boston: What to Expect

Structural carpentry pricing depends on several factors: the size and type of beam, the span it must cover, the loads it must carry, whether the work is in a basement or within finished living space, and how much temporary shoring is needed. A simple beam replacement in a basement might start at $3,500 to $5,000. A load-bearing wall removal in a kitchen or living area, with engineered design and permit, typically ranges from $8,000 to $15,000 or more. Complex jobs, long spans, or work that requires significant temporary bracing and coordination with other trades will cost more.

What moves the price up: the span of the beam (longer beams and heavier loads require larger, more expensive beams), the type of beam (steel costs more than engineered lumber), the depth of the space available (shallow spaces may require special beam types), the location (basement work is generally simpler than work within finished rooms), and the amount of finish work needed after the structural change (new drywall, trim, flooring, or casing adds cost). Permits and structural engineering fees are separate from carpentry and should be budgeted independently.

We recommend getting two or three estimates from qualified carpenters who understand structural work and can review the engineer's plans with you. Our estimate is free and comes with a realistic timeline and breakdown of what's included.

Beam Replacement and Load-Bearing Wall Removal Near Me: What to Look for When Hiring a Contractor in Boston

Structural carpentry is not a job for a generalist or a handyman franchise. You need a carpenter or carpentry shop that understands load paths, building code, and how to work safely with temporary shoring and engineered designs. When you're evaluating contractors, look for these markers of competence and professionalism.

• Verify that the contractor is fully insured with general liability and workers' compensation coverage, and ask to see the certificate.
• Ask for references from recent structural jobs, especially load-bearing wall removals or beam replacements, and call them to ask about the quality of work and the contractor's communication.
• Confirm that the contractor understands permits and will work with your local building department, including coordinating inspections at framing, beam installation, and completion.
• Ask whether the contractor works with a structural engineer or expects you to hire one independently (either is fine, but you should know who is responsible for the design).
• Get a detailed estimate that breaks down labor, materials, temporary shoring, and any other costs, so you understand where your money is going.
• Check whether the contractor is familiar with Boston's building stock and the specific challenges of your neighborhood (triple-deckers, brownstones, colonial-era frame houses, etc.).

Don't choose a contractor based on price alone. Structural work done incorrectly can be dangerous and expensive to fix. Choose someone who can explain the work clearly, has done similar jobs, and will coordinate with your engineer and building department throughout the process.
