Our philosophy is to provide our customers with the best product at the lowest price possible. Please read our recent article in Plymouth’s Old Colony Memorial to see how we do business.

Coastal Window and Door L.L.C was established in 2003 by co-owners David and Lynda Whyte. For 10 years prior to that, Dave worked for Thermal Industries as a manufacturers representative. With over 40 years experience in the vinyl window industry, Thermal Industries in Pittsburgh, PA is the oldest replacement window manufacturer in the country. Dave learned their products well and saw how other window dealers treated customers with pricing and service. He knew he could do better and decided to go into business for himself.

Coastal Window and Door started in our home and then moved to the current showroom on State Road in Manomet in 2005. We are a small company that takes pride in providing quality products and service at affordable prices. 

Our experienced installation team does high quality work.

No subcontractors are used. We install what we sell and we know our products well. Our team is honest and hardworking, and we guarantee our work and prices.
