Has been to my house twice to install windows and will be bringing him back to swap out the remaining old windows. Already feels warmer in my house with the quality windows he recommended. Justin is super professional and hard working. We had a bay window replacement and are very satisfied with the quality and how clean he kept his work space!

Justin is the kind of professional contractor you want to work on your home. He was fine with replacing just one window for us. No pressure, and the price was fair and the work was quality. Justin and Kevin came when they said they would, and we couldn't help noticing their attention to detail. They cleaned up as if they hadn't been here. Nice work, gentlemen. I would recommend them to anyone needing windows or doors replaced.

From estimate through to installation the experience working with Justin was excellent. He was responsive, fairly priced and did an excellent job on installation, would definitely recommend him to anyone looking. I always prefer working with a person rather than a company and will definitely call Justin for any future window/door needs.

Justin and team just completed my second window project. In 2020 they replaced the 1970 vintage windows on my ranch home with new replacement windows. The entire project went smoothly from measuring the old windows and openings, evaluating and selecting the various replacement options, removing the old windows and then finally installing the new windows. All steps were completed professionally with attention to detail along the way. This year Justin and team were out at my place again to replace the old glass patio door in the master bedroom and install a new screen/storm door for the front door

My husband and I hired Justin and his team to replace 10 windows and a storm door for us. They were prompt, professional, and efficient from the first phone call. We are thrilled with the quality of the work and the attention to detail. The time and care they took to ensure that we had a flawless finished product did not go unnoticed. The finished product has exceeded our expectations, and we highly recommend JWM!

Justin installed 23 windows in my moms new house. Couldn't be happier! He is an honest, kind and skilled craftsman! Everything is perfect and the price was very reasonable. Communication is fantastic. The windows were perfectly installed and work flawlessly. His trim work both inside and outside is meticulous. They worked fast and efficiently and cleaned up everything so well! I would highly recommend Justin and JWM windows for your project!

I've worked with Justin on two separate occasions, once to replace 17 windows, with new interior and exterior trim, throughout my house and the other for two storm doors and an entry door. Justin and his crew were excellent on both occasions. They got the job done quickly but more importantly they did great quality work and were highly professional. Justin was also very personable and took the time to answer any questions and concerns I had about the projects. I have absolutely no hesitation recommending him to my own family and friends, and if I end up with any more projects of my own Justin will

Great working with Justin! Excellent customer service--very attentive to our needs and our feedback. Worked around our schedule and was extremely responsive when we had questions during the estimating and planning phase. Superior attention to detail. Really cares about his craftsmanship. JWM replaced every window in our house--31 of them. I wish they did more than windows because we'd hire them back for more jobs if we could. I strongly recommend them for your next window job.
