Thompson Creek Window Company is the mid-Atlantic’s premier home improvement replacement products company. We have been manufacturing and customizing replacement windows, doors, gutters and siding specifically for the mid-Atlantic region for over 30 years. Our products deliver time and again – energy-efficiency (which can easily translate into savings on energy bills), increased home values, less maintenance and sheer comfort – throughout the year.

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.
