Incredible work, Incredible value, incredibly professional in every way. We had 13 windows and sliders replaced and the entire process was amazing. We started the process by getting 6 competitive bids by all of the highly advertised, EXTREMELY overpriced companies. Miller Window was highly recommended to us by a neighbor and we definitely want the pay forward that recommendation. Every step of the process was painless and pleasant. The crew worked clean, professional in every way and were a pleasure to have in our home. 100% recommend this company to anyone looking to replace window in their home.

Miller Window replaced every single window in our home for a total of 13 windows. I could not have been more satisfied with every step of the process. The initial consultation, thorough measurements, and quote was great. We got good and honest advice by Brian. The quote was very competitive. The installation went smoothly and was done by professionals who knew what they were doing even for a challenging bay window that required a bit of creativity. My family loves our new windows! I can't recommend Miller Window enough. I certainly recommend them to friends and family and will use them in the future.

Brian and Matt run a top quality window businesses. They don’t give you the run around or try to sell you there product. What you see is what you get, professional quality work. We had 8 different quotes when we were looking for windows. Some got back to us, some didn’t, some were way over priced and pushy, and some were just eh. We’re glad we chose millers window and are very satisfied with the install and professionalism of the crew.

Miller window is a top notch quality group of people. They came out as soon as I called them. Gave me a great estimate and followed through from start to finish keeping me informed of the progress.It was a custom 4 piece 8 foot sliding door. The work was professionally installed, excellent clean up and made sure I was 100% satisfied. No other company is that efficient. I've tried other companies and trust me, don't waste your time. The results I received were amazing!

We selected Miller Window as the contractor to replace the original windows of our 1987 home. The windows were ordered and arrive on the date specified. We had 15 window and all work with 100% complete within 3 days, which included replacing the wood trim on 8 of the windows. They were ontime, courteous and have had no issues. They handled getting the permits and arranging the inspector. We had a great experience with Miller Window, I would highly recommend them.

Outstanding company! The window installation crew was incredibly professional, and conscientious. They arrived on time and did nothing but work. I understand window replacement is messy, well, the only evidence left was new, beautifully installed windows. We also needed stucco work, and the crew was just as conscientious, and professional. I would absolutely recommend Miller Window. Thank you, Brian, Matt, and the crew.

Last month Miller Windows replaced 13 windows for us. We have high ceilings and eleven of the windows replaced line the upper walls of the living room and bathroom. Also replaced was a large arched window above our bed. These windows were difficult to get to and to remove. They were able to complete the job in a day and a half (would have only taken 1 day if not for the rain) and they did an outstanding job. The installers were very polite and professional as are the owners of Miller Windows. I love my new windows and recommend Miller without hesitation.

At my age, I never thought I'd fall in love again, but I am absolutely over the moon about my new energy-efficient windows. When it comes to investing in any relationship, good things come to those with patience. It was almost four months from getting Matt and Brian's quote to completion, but it was well worth the wait. The installers were like ninjas... so quiet that my three large dogs didn't bark once during the installation. They left everything nice and tidy and took away my old windows. Miller will also do the paperwork for any available rebates, but I opted to do it myself. I didn't want to bother them with that and I knew it might take a little longer for them to fit my rebate into their busy schedule. I highly recommend this company, but remember quality takes time.

I just had 9 original aluminum windows replaced on a 1970’s vintage house. Matt and Brian are easy to work with. The windows did take some time to arrive which was not a surprise because I was duly informed. The installation team was prompt and professional. I highly recommend Miller Window for your window replacement needs.

I called Brian and his team based on the recommendation of a family member and I'm so glad I did! The whole process was very easy and they were on time for every appointment. The windows were reasonably priced, good quality, and have really improved the curb appeal of my home! Installation only took a day for the whole house and the team of installers was very nice and polite! They cleaned up after the installation. One of the latches on a window stopped working in the first week of use, but after one call, they came out and replaced it with no problems. I'm super happy with the level of workmanship and service received and would highly recommend Brian and his team!
