At Thompson Creek, we take pride knowing that we offer you the best products, made with the best materials, all for the best value. After all, we've been custom-building windows in the mid-Atlantic for over 30 years.

Our experience has helped us engineer the best window available for our specific climate. We start by hand-picking only the finest suppliers in the U.S. in order to get the best available materials. We then custom-craft our windows right here in our Landover, Maryland, factory to your exact specifications.

Our attention to detail and precision building during the manufacturing process is what sets us apart from the rest. We pay close attention to your specific windows until your job is complete, scanning, checking and inspecting for quality along the way.

As technology has advanced, so have our manufacturing processes. Over the years, we've refined our building process to create the perfect blend of advanced machinery that is free of human-error with the attention to detail that is only possible with custom handwork. No window leaves our factory until it passes our strict Quality Assurance checklist. Once all of your windows have been constructed, we safely keep them in our warehouse until your personally scheduled installation day.
