windows - the eyes of your home

There’s no denying it: home windows truly are the eyes of your home, allowing you to see the outdoors and letting natural light in. Windows say a lot about the quality, design, and feel of your home. But they often go unnoticed until they become filthy or broken. We’d like to change that.

Windows can enhance the feel of your home. Natural light can change a room’s mood. Opening a window for fresh breeze to come in can change the trajectory of your day for the better. Secure windows can help you feel safer. Accent windows can update an older structure. Clean windows can make your whole world brighter.

Let’s not forget about the extras! Shutters and other forms of window updates and treatments can be transformative, enhancing your property value. Some are purely cosmetic to add curb appeal, but others are designed to protect your windows from inclement weather and to fight direct glare. The windows you’re “stuck with” are still open for interpretation with the extras that we have to offer. If you live in West Valley City, Taylorsville, Pleasant Grove, or the surrounding area, please reach out to us below.


Are you concerned about your home’s energy efficiency? Worried about a rising utility bill? Well, let’s talk about your windows. Did you know that ill fitting and older windows can be harming your home’s air conditioning and energy expenditure? It’s true. Heat transfer is a real problem with thin, damaged, or older windows. On the other hand, newer windows are designed to better insulate your home and keep your expensive air conditioning within your rooms. Reflective films are effective at preventing direct sunlight from penetrating your windows and heating your home during the long Utah summer months.

Don’t fall into the thousands of homeowners who put windows on the back burner, only noticing them when spring cleaning rolls around. Windows are an integral part of your home that can make life bright, beautiful, and even more energy-efficient. Let us help you take your windows to the next level for maximum satisfaction.


We can help you plan, design, and build your dream!


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.
