Complete Home Renovation Services

A house renovation goes beyond updating a single room. It addresses how the entire home functions, and that requires a contractor who understands structural systems, permitting requirements, and the particular challenges that come with Greater Boston’s housing stock. Bastos Construction has spent years renovating triple-deckers in Somerville, Colonial-style homes in Medford, and Victorian-era properties in Cambridge, which means the surprises common to older construction rarely slow our projects down. Browse our completed projects to see the range of residential renovation work we have done across the region.

Renovation work at Bastos encompasses the full range of residential scope:

• Interior layout changes. Removing load-bearing walls, relocating doorways, and reconfiguring room arrangements that no longer match how a household operates. These structural changes require engineering knowledge and permit coordination, both of which Bastos handles directly.
• Whole-floor renovations. Updating an entire level of the home through new flooring, fresh framing, updated electrical, and ceiling work that brings the space in line with modern standards without affecting the character of the property.
• Mudroom and entryway construction. Adding functional transitional spaces that manage daily foot traffic, winter gear, and household storage without cluttering living areas.
• Sunroom and enclosed porch conversions. Transforming existing three-season structures into year-round living spaces through proper insulation, window upgrades, and heating integration.

Home Addition Construction in Somerville and Surrounding Communities

A home addition increases your square footage without requiring a move, and in Greater Boston’s competitive real estate market, that added space carries real value. Bastos Construction designs and builds additions that connect cleanly to the existing structure, match the exterior aesthetic, and meet all local building code requirements from the start.

Common addition types we complete include:

• Room additions. Adding a bedroom, home office, or family room to the main floor footprint. Site conditions, foundation requirements, and lot coverage regulations all factor into the planning process before a single frame goes up.
• Second-story additions. Building up rather than out when the lot does not allow for horizontal expansion. Second-story additions require careful structural assessment of the existing foundation and first-floor framing before construction begins.
• Bump-out additions. Smaller extensions that expand an existing room by several feet without a full foundation pour. Bump-outs solve specific spatial problems, such as a kitchen that needs more counter space or a bathroom that cannot fit a double vanity, without the full cost of a major addition.
• Attached garage conversions. Converting attached garage space into finished living area while preserving the structural connection and exterior appearance of the original home.

Structural Work and Permit Management

Renovation and addition projects in Massachusetts require building permits, and in many Greater Boston communities, the approval process involves multiple inspections and agency sign-offs. Bastos Construction manages permit applications and coordinates with local building departments so that work proceeds on schedule and passes inspection at each phase.

Structural modifications are handled with the same attention. Opening walls, adding point loads for second-story construction, and tying new framing into existing foundations all require proper engineering to ensure the finished result is sound and code-compliant. We work with licensed engineers as needed and maintain detailed project documentation throughout construction.

Historic districts in Cambridge and certain Somerville neighborhoods carry additional review requirements for exterior changes. Our familiarity with these processes means homeowners avoid the delays that catch less experienced contractors off guard. In cases where renovation work uncovers existing water or moisture damage, our water damage restoration service addresses those issues before new construction proceeds.
