New Window installation

It’s no secret that the best windows are only as good as the installation behind them. For this reason, our team is dedicated to making your next window replacement or installation project the greatest home improvement project your family’s ever taken on. In our years of service, we’ve come to realize that the best quality experience lies in the small details. All of our hard work and craftsmanship that we put into our projects would mean little without the proper tools and know-how. Luckily, our experienced technicians have tackled big and small home renovation projects throughout the Wasatch Front, ensuring you’re only working with the best in the business.

You can rest assured that your new windows will boost your home’s curb appeal, keep debris out, let natural light in, and ensure that your home is insulated to keep your family warm in the cold months. If your energy bills are skyrocketing, then replacing your windows with our high-quality ones is the solution. We proudly serve Salt Lake City, Murray, Orem, Provo, and surrounding cities. Reach out to us below to learn more.

Upgrade with new windows

Maybe you’re considering a new renovation project but don’t know where to start. Our suggestion to you is to prioritize getting new windows for your home to reap the numerous benefits they can bring to the rest of your home and family. We know that window replacement may not sound like the most exciting project, but it’s a worthwhile one—especially if you want to increase your property’s value. Maybe you’ve worked with other renovation companies in the past and felt like you couldn’t speak up about your preferences, and as a result, you’re too nervous to try it again. We understand. In our years of work, we’ve heard all different types of stories from homeowners who are just like you.

The difference between Mountain States and those other companies, however, is that we will always put you, the customer, first. This means that your ideas will always be at the forefront of our projects, and our job isn’t complete unless you’re satisfied. We’ll walk you through every step of the project to ensure we’re all on the same page, and we’re open to answering any questions you may have. We invite you to reach out to our professionals below.

I had my windows installed about 18 months ago. The first winter that happened I started to get water coming through just a little. Later, I started getting full on leaking. I can never get anyone to call me back to address the issue. I don't feel at all that I got a good value.Update: I was contacted by the company, and they came out and resealed a lot of the windows. They were nice and attentive. I'm still not sure how great these windows are as I'm not a window person, but the company itself is very good.

We are very pleased with our windows! Dave did a good job of sharing all of the information and what to expect. The install was quick and seamless and done in one day. Overall, we had a great experience and would recommend Dave’s friendly service to anyone.

I am completely impressed with Mountain States Windows and Siding. We needed to replace a very small section of vinyl siding on our house. Most companies weren't willing to help me find a match or sell me such a small amount. But Mountain States was so helpful! They were responsive, knowledgable, and generous. They really bent over backwards to help me get the couple pieces I needed (and quickly, too!). There really is no job too small for these guys! I highly recommend this professional, accommodating, honest company.
