Window Installation Specialists were referred to us from friends, and they didn't disappoint! Had a really great experience with Melissa, Bill, and the rest of the crew. Melissa and Bill did a comprehensive job of going through options and staying in touch throughout the process. On installation day, everything went without a hitch. Tim even custom-cut the trim from one of the newly installed windows where there was a tight fit between the window and a perpendicular wall.
Overall, highly recommend and I can't wait to use them for our next window project.

We had a very good experience with Window Installation Specialists. Melissa came to the house to give us our options for replacement windows. We are dividing our whole home replacement into phases. Phase 1 is complete and we couldn’t be happier. Bill came out on the first day to make sure all was going well. The installation crew is great! They’re professional and go beyond expectations to make sure the job is done satisfactorily. Definitely recommend!
Phase 2…Complete! We love our new windows and doors! We’ve had a continued great experience with Windows Installation Specialists. I can’t say enough about the crew, Matt, Tim, and Steve.

They work very hard with the prep, installation and clean up. I wouldn’t want anyone else doing a whole house window installation. Thanks guys! Highly recommend!

OMG I absolutely love my new windows!!!!!! We went from being the ugliest house on the block to the best looking house!!!!! And our installer Tim Lucas did the best job from taking out the windows to putting on the finishing touches. The finish too is as about as professional looking as it gets! Not a mess or globs of caulk anywhere. Smooth and neat. We have a few more windows that we’ve decided need to be done because they don't look as nice as our new windows and Tim is who I’m going to have them do it.

I can’t say enough about my new 13 Pella brand windows. Melissa guided me to choose the best styles. Her expert installers were proficient, neat, and tailored the window trim to blend with the outdoor stone house structure. So glad my friend recommended Window Installation Specialists. Incidentally, they replaced 2 doors also! The total price was much less than competitors. Trust this review!
