There are many reasons why Haverhill homeowners pick Pella for their replacement window and door needs. Founded in 1925, Pella is privately-held. Our success depends upon customer satisfaction, not stock prices. All of our high quality windows and doors are produced with care and serviced by Pella’s unique Direct Sales Network. Unlike most other window and door companies who sell exclusively through third-party channels, Pella has dedicated window and entry door showrooms the U.S. and Canada. This unique way of operating our business gives Pella clients in Haverhill a highly personal experience with the support of a local to Haverhill, Pella-certified team. Whether you are looking for the beauty of wood, the strength of fiberglass, or the low maintenance of vinyl—Pella has a high quality, energy efficient and durable solution.
