Regardless of the type, style and size house being built or renovated, nothing accents a home’s exterior appearance quite like quality windows and doors.

DBS offers a vast assortment of quality windows, doors and stylish hardware from name brand manufacturers to accommodate your every need. Our Product Specialists also provide technical guidance and recommendations as to the highest quality and most attractive windows and doors that best suit your home’s architecture and allotted budget.

Given the importance of conserving energy, DBS emphasizes windows and doors that meet or surpass Energy Star® performance rating standards and qualify for Federal Energy Tax Credits. Energy efficient doors and windows significantly lower utility bills by protecting against New England’s freezing winters, summer heat, and coastal moisture. They also help maintain consistent room temperatures, improve indoor air quality and make your home noticeably more peaceful due to their noise reduction characteristics.
