Testimonials
M3 Window & Doors was great to work with and did a fantastic job! We love our new windows and we have noticed a big difference in our house already. It’s a family company and they treat you like that as well!
Andy Killpack
Great crew!! I got a friend’s a family quote from a buddy of mine but they have a lot of overhead. I looked around for a mom and pop shop and stumbled upon M3 Window & Doors. Bonnie came by to give us a quote and explained their products in understanding detail.
Johnny Le
Worked with Bonnie, Nick, Andrew, and her father Kevin. Windows took less than a month to order and install. They are nice, pricing is fair (hard to find that), locally owned, and quality work. Even took to the time to give me tips on a few other projects.
They even worked with me on some modifications to resize a few windows, and they had no issues letting me complete the modifications to save some money.
No complaints, only good things to say.
Christian Tekiela
Kevin is a very responsive and accommodating owner. Nick, and Andrew were both great and professional with what they do. Exceptional customer service and quality all the way around. Brook & Bonnie know their craft and do it well. I’ll be talking with you all again in the future about doors for my house. Exceptionally rated, recommended to all, and will use again.

Pete Mittanck
We have been building a new mountain home above Heber (8000 Feet). This required special glass and the ability to work during a very snowy winter. We had issues with the weather, workers and framing problems that Kevin, Bonnie and crew worked around. They have been nothing but great to work with. I recommend them for any of your glass needs.
Nick Kryger
It was so nice having Bonnie come to my home and explain all the window options and which style would be best for me. I don’t know much about windows so her helping me make those decisions made it way less stressful. The installation was faster than I expected and everyone that works here is so nice!
