General contractor in Boston, MA

Boston is a dense, historic city where the housing stock spans centuries. Neighborhoods like Dorchester, South Boston, Jamaica Plain, and Charlestown hold row houses, triple-deckers, and brick brownstones built from the mid-1800s through the early 1900s. Flat and low-slope roofs are common on attached buildings, and aging wood-frame construction means fire and water damage can spread fast between units. Harsh New England winters, with freeze-thaw cycles and heavy snow loads, accelerate wear on roofing, siding, and windows across the city.

Boston's Dense Housing Stock Demands a Full-Service GC

Boston's attached housing creates a specific roofing challenge. Flat and low-slope roofs on triple-deckers and row houses trap water and ice in ways that pitched suburban roofs do not. A failed membrane or cracked flashing in February can mean interior water damage across multiple floors before the snow even melts. We work on these roof types regularly and know where they fail first.

Fire restoration in Boston moves fast because the buildings do not. When a fire touches one unit in a wood-frame triple-decker, smoke, soot, and water from suppression efforts can reach adjacent units through shared walls and floor systems. We coordinate directly with insurance carriers to document scope, stabilize the structure, and rebuild from the inside out. That process requires a licensed general contractor who can handle every trade, not a patchwork of subcontractors.

Siding on Boston's older wood-frame buildings is not a cosmetic project. Decades of freeze-thaw cycling crack and cup original clapboard, and moisture gets behind it before most owners notice. We replace siding on buildings across Dorchester, South Boston, and Jamaica Plain, and we tie the work into window and trim details so the envelope is sealed when we leave.

Every service, available in Boston, MA

Roofing is a constant need in Boston, where flat and low-slope roofs on attached buildings collect ice and standing water every winter. Siding replacement is in high demand on wood-frame triple-deckers where moisture infiltration and rot set in over decades. Insurance-based fire and flood restoration is critical here because fires in dense row house blocks can affect multiple units at once. We also handle window replacement on older buildings where single-pane and storm window setups no longer meet energy or weatherproofing demands.

Contracted K&B as our general contractor to renovate our home. I strongly recommend this company. Reaching them was easy, professional from the initial pricing, through to final completion. Even with the many surprises that were encountered, the work they delivered exceeded our expectations. Excellent workmanship, site was cleaned daily and they provided a clear daily schedule.

After extensive research, I came across K&B contracting. They went above and beyond to make sure my project was on schedule and even saved me money on some materials with their suggestions. Would definitely recommend!

Charles Cuellar Google review · March 2026

We worked with Kevin to rebuild our townhouse after fire damage, and we couldn’t be happier with the experience. He is hardworking, responsive, efficient and very easy to communicate with throughout the entire process. He kept things on track and made a difficult situation much easier for us. We are so grateful to have him. It was a great pleasure working with him, and we highly recommend him and his team.

General Contractor FAQ for Boston, MA

Common questions from Boston, MA customers about our services, process, and coverage.

Yes. Multi-unit fire restoration in Boston's wood-frame buildings requires a licensed general contractor who can manage structural repairs, smoke and soot remediation, and interior rebuilds across separate units. We work with insurance carriers and coordinate the full scope from stabilization through finished reconstruction.

Modified bitumen and TPO membrane systems are the most common and durable choices for flat and low-slope roofs on Boston's attached housing. These materials handle standing water and ice better than older built-up roofing. Proper drainage and flashing details at parapet walls are just as important as the membrane itself.

Yes. Siding replacement on attached or semi-attached buildings in dense Boston neighborhoods requires careful sequencing to protect adjacent properties and maintain access on narrow lots. We work on wood-frame and masonry-clad buildings across the city's older residential neighborhoods.

Original wood windows in Boston's older housing stock are often single-pane and no longer seal well against winter cold or summer humidity. Replacement with insulated units stops drafts and reduces heating costs. In some historic districts, window style and profile matter, and we can discuss options that fit the building's character.
