Gerry Dunleavy Construction Corporation is a Winchester, Massachusetts building contractor that says it has been building, remodeling, and repairing homes for nearly four decades. The company offers home remodeling, additions, design-build, new construction, decks, and handyman work, and says it serves the North Shore and Greater Boston. Older Houzz reviews describe substantial residential projects, including basement renovations, additions, kitchens and bathrooms, mud rooms, banisters, historic-home work, porches, and new construction. Homeowners repeatedly mention detailed carpentry, coordination with architects and designers, professional crews, clear communication, and work completed on schedule. The written reviews are from March through July 2015, while the Houzz profile currently lists 4.9 stars from 13 ratings and 39 projects. A BBB profile lists an A+ grade, a Massachusetts Home Improvement Contractors license number 108859, and 45 years in business. The reviews portray a contractor suited to complex renovations and additions that require coordination across design, carpentry, and subcontracted trades. One 2015 reviewer praised competitive pricing but said cleanup around a garage could have been better; that is a concrete point to clarify when discussing site protection and closeout. The company states that it handles carpentry in-house and subcontracts plumbing, electrical, plastering, and pointing, so confirm which portions of a proposed project will be performed by its own staff. Dunleavy appears suited to homeowners planning a major remodel, addition, or custom home project who want a managed design-and-build process. Before booking, confirm current availability, scope, schedule, subcontractor responsibilities, cleanup expectations, and the status of the listed license.

“Gerry Dunleavy is a leading construction company which provides home construction and remodeling services in Boston.”
Gerry and his team renovated our basement. It was an ambitious project made easier by the professionalism, expertise and dependability team Dunleavy provided us. Extremely detailed oriented, they worked with our architect and designer flawlessly. We were impressed by the precision of timing, the transparency with the subcontractors and their effectiveness in minimizing the hassles for the owners by taking care of it all. We particularly liked the carpentry, they took great care incorporating elements of the existing woodwork in the house. They were flexible and prompt at responding to inquiries and accepting changes.
As a design professional I have worked with many building professionals over the past 30 years on a national level. Dunleavy Construction is the real deal. From the moment you call their office to the final item to be completed on the project Gerry Dunleavy attention to detail and management is priority number one.
Gerry and his team were outstanding...from the initial follow-up to my first inquiry to the final walk-thru of the finished project. Embarking on a major addition....a kitchen and three bathrooms...is a daunting process...and living through it adds another layer of stress. But the Dunleavy crew made it all bearable.
I have hired Gerry Dunleavy for several projects including a major renovation of my home several years ago. I have also hired them for smaller jobs through their handyman division. When a heating pipe burst in our finished basement, I contacted several contractors, but hired the Dunleavy firm. They were very responsive, professional, reliable and offered good advice.
Gerry and his team were professional, courteous, and the work was beautiful. We did a design build of a mud room with his team - so went from concept to plans to build to finish/paint. The team kept the space neat, communicated well and were sensitive to having 3 kids and a dog living in the house while they worked.
