Thompson Creek Window Company is the mid-Atlantic’s premier home improvement replacement products company, and the 2012 #11 home remodeling company in the United States, according to Qualified Remodeler magazine’s annual Top 500. We have been manufacturing and customizing replacement windows, doors, gutters and siding specifically for the mid-Atlantic region for over 30 years. We are part of this community and proud to help our friends and neighbors improve their homes’ appearance and value. Our products deliver time and again – energy-efficiency (which can easily translate into savings on energy bills), increased home values and curb appeal, less maintenance and sheer comfort – throughout the year. Thompson Creek is not just selling windows, doors, gutters and siding. We are selling our family, our reputation, and our commitment to excellence. We are your neighbors, your friends, and your family. And we are committed to these relationships. Our windows and gutter systems are custom-manufactured, installed and serviced from our family-owned and operated factory in Landover, MD - eliminating any middlemen. This level of control over product design and lead times helps to ensure we maintain our competitive edge. And best of all - we back everything up with a transferable double lifetime guarantee.
