See Why West Mifflin Residents Love Window World

Window World of Pittsburgh has been truly outstanding to work with. The quality of their product and the craftsmanship of the installers was on par with quotes double and triple the price. Their sales are professional, informative and in no way pushy. Mark helped my family make the right choices for us and backed it up with pricing and service that has been top tier. Window World should be one of your first stops for a quote!

This is my second time working with Window World. I really enjoyed the customer service and assistance of transitioning my old windows to new. James Leslie was great to work with by answering all my questions and guiding me through the process. The installer was fantastic. His craftsmanship was excellent and very professional. His attention to detail and cleanup was terrific.
Josh B.
We had 19 windows installed. After measuring, the windows were made and installed in a timely manner. We love the new windows and their awesome guarantee. Everyone made sure we were happy and also gave us instructions for cleaning. I highly recommend Window World.
