Sanford Custom Builders is a Wellesley-based custom-home builder and renovation firm. Its own website places the office at 310 Washington Street, and Houzz identifies Marc Kaplan as owner and president; the company presents itself around custom homes, renovations, and general contracting. The dated written reviews are consistently positive. In October and November 2014, homeowners described substantial custom-home projects, including an 11,500-square-foot house with a barn and in-law home, and praised careful attention to detail, budgeting, supervision, finish quality, availability, and prompt resolution of issues. An architect also described repeated high-end residential collaborations and Sanford’s work with subcontractors and artisans. The business has current third-party licensing evidence: the Massachusetts registry lists license 195128 as active, while BuildZoom also lists 146769 as active. BBB gives the company an A+ grade and identifies it as a non-accredited home builder. BuildZoom reports 10 permitted projects and a score of 100; Houzz shows 16 projects and a 5.0 rating from five reviews, all dated 2014. The review history is detailed but old, so ask for current references, schedule expectations, and the exact scope and licensing basis for a new project. Sanford is a strong fit for clients planning high-end custom construction or major residential renovation who want an involved general contractor; confirm the present project team, active license details, and recent comparable work before booking.

I have worked with Marc and his team on several high-end residential projects and am extremely pleased with the results. Marc is very efficient, a good communicator and very client-oriented. He respects the process and the design professionals involved and he works diligently to realize the project intent. Sanford works, on a regular basis, with the region’s best sub-contractors and artisans to bring a level of finish uncommon in the industry. I look forward to my next collaboration with Sanford Custom Builders and know that our clients best interests will be in the capable hands of a quality general contractor
The project we undertook was extremely complex and took much longer than we had anticipated. We relied on Marc to help us work with the architect to achieve the result that we wanted, helping us balance the cost of the design elements that we were creating with the ultimate old-world charm that we were striving to achieve. Sanford has very high standards and Marc delivered to us a superior home of the utmost quality.
I am writing to thank Marc Kaplan and Sanford Homes for a job well done! When we first began this project I don't think I truly realized the enormity of developing a highly detailed 11,500 square foot stone and shingle house, a large barn with a greenhouse and a home for my in-laws. However, Marc and his staff handled our project magnificently and professionally at every turn. The pre-construction value engineering and budgeting was constructive and accurate. The scheduling, sub-contractors and supervision was professional. The timing, delivery, and pricing was excellent. We were always treated fairly and respectfully.
This is the fifth time we had have built a home, and it is definitely the best built of them all. The finish work is of uniformly high quality, and the bones are rock-solid. We were also delighted with the enthusiasm, attention to detail and care brought to the job by our project supervisor. Finally, whenever issues did arise, Sanford was quick to resolve them to our satisfaction.
I appreciated Marc’s guidance and thoughtfulness throughout what turned into a substantial home construction project. Marc and his foreman were bright, articulate, and flexible yet firm in making sure that there was careful attention to detail. These attributes were shared with our architect and his associate to form a successful working relationship. Marc’s consistent availability and honesty were, and remain, important to us.
