Hear from our co-founder Levi as he introduces the Performance Windows mission and reads a few of our 5-star reviews.
Just had our new windows and sliding door installed today and they look amazing! Really nice and professional crew showed up on time and got right to work. Six windows and a sliding door (removal, install and cleanup) took them about 3 1/2 hours to finish. Matt was awesome and walked me through all the features and details about our cool new gear. Everything looks great and I will recommend PW to everyone I know.

The windows looks amazing and I was amazed by the quickness and attention to detail the instalation team had for the window even when it ment redoing curtain parts of the job and the end result looks amazing 10/10
Colorado Springs, CO
The windows look great, clean bright finish,, excellent look and feel. Noise control is good, our street is not too bad. Temperature control in this hot summer also very good. Looking forward to comparing cooling (and heating bills) as the year goes by.
All in all, and excellent decision, great quality product and work. Well worth the investment!

The first picture is how the house looked before and those windows were all the way around the house. The middle picture is the front of the house and the last picture is the single window that is shown in the first picture. During installation, they were very friendly courteous, and they did an excellent job at removal and taking away all debris Since installation Since installation the air conditioner does as much either

I had 3 large windows and a sliding door installed, and had a great experience throughout! The whole process was easy and the installation went smoothly. Josh was a huge help- he walked me through different products, explained the benefits, and made sure I had all the info I needed. Everything looks great!

We recently had our windows replaced and Performance Windows did a great job. They arrived as scheduled, completed the work as promised and left my house cleaner than when they arrived. I noticed an immediate improvement in the sound level and can’t wait to see the improvement in our utility bills. I would definitely recommend them for both quality of product and quality of service.
Seattle, WA
Everyone at Performance Windows were professional. The salesman answer all our questions. The guy who came and measured the window was very thorough and measured inside and outside and on occasion double checked his measurements. The installation crew was very well organized and skilled. It only took a few hours to install our windows. They cleaned up well afterwards. I would recommend Performance windows. Oh, by the way the windows are high quality and very functional and look like they will be easy to clean. To score points with the wife I think I will volunteer to clean windows!! Again I recommend Performance Windows.
Kaysville, UT
We unfortunately did not have the funds to buy the windows at the time offered but were impressed by the quality of the product and can not say enough good things about the sales person Bryan. It was incredibly refreshing to have someone in sales that really seemed to have our best interest in mind and his approach was the only reason we even considered making the large investment in new window. If we ever decided to get new windows definitely calling Bryan and the company to purchase them.
Las Vegas, NV
I love our new windows! Our house feels like a brand new home. From the presentation to the install, Performance Windows was transparent, professional and just plain nice. The crew was great and very careful not to leave any debris from our old windows. The best part, it only took ONE day!! Thank you, Performance Windows for giving our home new life! 🙂
Dallas, TX
I just got beautiful new windows installed by Performance Windows. This was a great experience from start to finish. Everyone we dealt with were incredibly polite and professional. The installers were very courteous and respectful of our home, and they completed the project quicker than expected. And did I mention that the windows are beautiful? They are, and they have a bunch of amazing features that I didn’t even know were available. And I should also mention the excellent lifetime warranty on parts and service. I highly recommend this company.

Super professional. Josh, Cody and their crews are top notch. I’d recommend them next time I need to get windows repaired.

Dylan did a great job on the install! It was quick and easy. The windows look great and came in a month earlier than expected. Cody and Wadson were great and so communicative throughout the process. The lifetime warranty is icing on the cake. I highly recommend them.

We just had all of our original 23 year old windows replaced by Performance Windows. They were installed beautifully inside and out! We went with the bronze frame on the outside to match our iron front door and almond frame on the inside. The crew was amazing—professional and courteous! We highly recommend Performance Windows! Very satisfied!

Boise, ID
We just had our windows installed today. Hayden is the salesman we worked with to start and Hiram was the installer. Hiram and his team were professional, respectful of our space as they installed, and cleaned up everything. They even arrived earlier than the time slot scheduled which was cool. Hayden has also been very personable and professional with solid communication during the timeline from purchase to install. The finished product looks great! Quality windows and a much needed upgrade to the house.

Performance Windows did an excellent job from start to finish. They completed the entire installation in just one day, working efficiently and professionally the whole time. The team took the time to walk us through each step, making sure we understood the process and were happy with the progress. We are especially pleased with our new sliding glass door—it looks fantastic and works perfectly. Overall, they did a great job, and we couldn’t be happier with the results. Highly recommend!

I am so glad I had Performance Windows replace my windows. Matthew and his amazing crew were efficient, knowledgeable and very customer oriented- they all made sure I was satisfied with their work. It is refreshing these days to see people that truly have a high work ethic and take personal pride in their work. The windows are beautiful and I can already tell they will be energy efficient. I would highly recommend this company.

Performance windows did a great job installing our new windows. The windows look great and are very high quality. The installers worked fast and efficient and did a great job. Some of our old windows were very challenging to get out and they handled like pros.
Dallas, TX
We have had our windows installed approximately a month ago and are happy with the results. The experience from start to finish has been great. Everybody has been available and willing to answer questions when we reached out. The Techs are very professional. They arrived and completed our house the same day. The windows look good and we have already noticed the difference with heat and noise levels.
Tucson, AZ
Overall, I would definitely recommend performance windows to anyone. Our windows were original with the home (1969) and we’ve noticed a HUGE difference in noise and bugs since they’ve been replaced. They enhance the entire look of the house as well. We can’t wait to open them up in the fall!

FAQ
Got questions? We’ve got answers. And we think you’re going to like them.

How long does the process take?
From your first quote to your final install, the whole process takes about 10–14 weeks. Here’s how it works:
- We measure your windows 1–3 weeks after you give us the green light.
- Then your custom windows are built.
- Once they arrive, our install team gets them in—usually in one day, maybe two for big jobs.
How do you compare to brands like Pella?
Our premium, energy-efficient windows are often a fraction of the cost of Pella and other brands. Why? You’re not paying for showroom overhead, just great windows and great service.
What are the potential downsides?
Replacement windows slightly reduce your visible glass area by an inch or two. But you’ll get back better insulation, quieter rooms, and a house that feels and looks better. The trade’s well worth it!
When should you consider replacing your windows?
Tell tale signs that it may be time for new windows? When they’re hard to open, drafty, look old, or don’t regulate the temperature of your home well. Or anytime you want to improve your energy bills, comfort or curb appeal!
How long does the warranty last?
As a national supplier for Alside, our windows are covered by Alside’s Limited Lifetime Warranty. Most standard windows have a lifetime warranty, including glass breakage!
