Ron Dulmaine and Sons is an independently owned garage door installation and repair business established in Sandwich, MA in 1987 by Ron Junior to service all of Cape Cod and Martha's Vineyard. As the business grew, Ron Senior (Pops) retired to the Cape after 43 years as the manager of Fimbel Door Company in Worcester, MA to assist with sales and installations. After growing up "in the business", Jason went off to college, entered the computer field, but decided he missed the construction aspects of installation. Ron's second son, Sean, also enjoys working in the family business. Ron Dulmaine and Sons is known throughout Cape Cod and Martha’s Vineyard for the high quality products and exceptional service provided. Pops, Ron, Jason, and Sean pride themselves on prompt, courteous service. Phone calls are returned in a timely manner. We are fully insured and licensed.

Ron Dulmaine and Sons buys only from well-established, highly reputable suppliers and manufacturers. We offer a wide range of garage doors from Haas Door, Fimbel Architectural Door Specialties, Clopay, and C.H.I. as well as electric garage door openers and accessories from Marantec and Liftmaster.
