About New England Gypsum & Karpp
Your New England construction products supplier



Construction professionals in MA, ME, CT, and NH have known for decades that when it comes to sourcing New England’s best selection of building materials and construction supplies, they have two great choices:
New England Gypsum (NEG) – Founded in 2018, New England Gypsum (NEG) has grown quickly, becoming a trusted partner for local residential and commercial construction customers. NEG serves clients through its building supply yards across new England. (Hartford, CT; Milford, CT; South Portland, ME; and Manchester, NH)
Karpp – a mainstay in New England building supply since 1979, serves commercial and residential customers through its construction materials yards across Massachusetts. (Abington, Attleboro, South Boston, Woburn)
