Thompson Creek® Window Company offers homeowners an alternative to the middleman experience…a better way to get more for your money.

Homeowners want more than well designed windows and doors, including benefits like comfort, beauty, and energy efficiency. The best window or door in the world serves no purpose until it becomes part of your home. To provide you with this, we’ve made expert installation a part of every product we sell.

Product durability is extremely important to our customers. Every product that we design, build, and install must stand up to the rigorous weather conditions of the mid-Atlantic, as well as the test of time. That’s why we invest more money in higher quality parts and installation materials than other companies. Thompson Creek products are backed by our No-Hassle Warranty and Buyer Protection Guarantee. We do this because homeowners see value in quality and durability, while a middleman is only interested in low cost so he can make a larger profit.

You get more for your money at Thompson Creek.

Excellent windows

Thompson Creek Window is simply an amazing company. From beginning to end of our job, every person we dealt with was professional, courteous, and competent. They followed through on every detail during each step in the process. They replaced all the windows in our two story home in one day, despite terrible winter weather. Their custom made replacement windows are a perfect fit. No more leaks or broken slides. Every business could take a lesson from their playbook from customer relations to delivering a quality product.
