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

They showed up with a smile and left with a smile… they took time to make sure we were happy and everything was perfect! Will definitely use his service again!!

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!

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.
