From Dartmouth to Duxbury, Wareham to Wellesley, architects, builders, and homeowners know that Dartmouth Building Supply is the preferred choice for millwork and molding, because we offer unequaled quality, competitive pricing, and exceptional customer service.

Details transform a space from ordinary into extraordinary. This is especially true in a room. Revive a room by replacing the casings and baseboards or add a “wow” factor with a crown or chair rail. Moldings can take a room or an entire home from flat to fabulous in no time at all.

Dartmouth Building Supply is very particular about the moldings we offer. After all, unique, premium-quality, custom moldings are an easy way to create a high-end look, and we want your home to be special.

For over 25 years, A&B Wood Design has provided a line of Architectural Mouldings that offer a more custom approach to the traditional “commodity” profiles available. All products are stocked in Gesso Primed Finger-Jointed Pine and Poplar. Some of our profiles are available in MDF, and 8 of our most popular crowns are available in extruded PVC for exterior use.
