The SBS OneSource Story

Always find a way to Say Yes.

President and Owner Chris Dias started Specialty Builders' Supply in 2001 in Brewster, MA as a supplier of exterior products for the home building industry on Cape Cod and Martha’s Vineyard. Chris was the only employee. Fast forward 24 years later to 2025, where from the original office and warehouse space in Brewster, SBS OneSource has expanded to include two full-service Contractor Lumber Yards in Harwich and Vineyard Haven, an extremely unique Window and Door Showroom in Pembroke, and to a brand new headquarters and Window and Door Showroom in Harwich.

SBS OneSource is a locally owned and operated Cape-based company born out of a focus of providing architects with industry leading products to specify and providing builders the flexibility and support that they need from a building materials supplier. From the original office and warehouse space in Brewster, SBS has expanded to include extremely unique Window and Door Showrooms in Pembroke and Harwich, full-service Lumber Yards in Harwich and Vineyard Haven and new headquarters in Harwich. Architectural products that builders appreciate all supported by a team of over 50 gifted professionals who cover not only the Cape and the Vineyard but most of MA with a wide range of home building products that include many exclusive window and door lines.

The strength of SBS is the unique personnel who execute the "Say Yes" mantra. In the Window and Door Division, Marc Lima is one of the most detail oriented fenestration experts you could find. He has intimate knowledge of the Martha’s Vineyard market and wears his total commitment to customer satisfaction on his sleeve. Freddy Maguire is a well-seasoned 25+ year window & door salesperson who can properly identify the correct product for any type of project and make it happen. Narcisa Lazic has broken all SBS records for success in a short time frame. Her easy and friendly demeanor with her keen sense of understanding products and projects helps her to quickly develop trust and confidence and then she delivers. Add to this Christine Ayotte, who's experience in the housing sector and attention to detail is invaluable, industry veteran Craig Fischer, who brings a wealth of experience specifying windows and doors for over 20 years for a national brand, and Ken Michaels, whose experience as a builder allows him to speak and understand the lingo with ease.

The OneSource Architectural Windows and Door sales team of fenestration pros work with architects and builders to specify the right product for the job. Regardless of where the work is being done, it is always executed with Dias’ “Customer First” mentality: Say Yes!
