These windows are the same quality as all the other vinyl replacement window companies that I got quotes from. (Others claim theirs are unique/superior, but it looks like the only difference is the logo on the locks/latches.). Window World was much less expensive than the others, and the install was done on schedule (except for a delay due to rain) with professional results, and they left everything as clean as they found it.

What a wonderful company to deal with. I used window world for another rehab project 2 years ago, they did such a wonderful job there I used them on this most recent rehab project. The technicians are knowledgeable, polite, and efficient. For this latest project, for installing 13 windows, I received a quote of $22,000 from Thompson Creek. My quote from window world Frederick, was 1/3 of that price. I would definitely use window world again, and I refer them whenever I get the chance. Thank you so much for a job very well done

I’ve used Frederick Window World several times. Once for a whole house window replacement, and three more times for smaller one window replacements and a repair.
Always thorough and quality of service just what I would hope for. I really appreciate having contractors that I can count on and Ryan and his team are my “go to” for anything window related.

My new windows and door were installed with great care and precision. The workers were very friendly and cleaned up after themselves. I’m very happy with the windows and door!

Had all new windows and patio door replaced. Crew was on time and extra careful that our cats didn't get out. For the first time in 20 yrs. I can see out our windows. Our window seals started to fail 6 yrs after house was finished. Great Job.

Window world did a great job on our home. Replaced all the original wood windows that were rotting and drafty with new vinyl windows. After 4 years, they still all look amd work great.

This is the 2nd time we have used them. We used them at our old house we just sold and then our new house we just bought. Both times they have been great and the crews are very respectful. They are very efficient and get the job done right. Window world’s pricing is also very good with good quality windows. We wouldn’t hesitate to use them again or recommend them!
