My home was cosmetically remodeled, so it has lots of issues. But windows are one of the biggest. Two basement sliders were improperly installed, with one leaking badly during heavy rains. Then there was a garden window in the kitchen that was so poorly sealed, it was covered in mold and was unusable.
Randall drove almost two hours to take a look at them and give me an estimate. We discussed what I wanted done, and he never once pressured me to into something I didn't want. Even when I asked him what it would cost to replace all the windows or a door, he didn't bite. He asked me how long I planned to live in this house, and advised me against projects that weren't critical.
After locking in a discounted price, I waited for the windows to get shipped. They came in much earlier than expected, and Zach got me scheduled for install within a couple days. It took a full day to install all three, mainly because the poorly-installed windows were difficult to remove. But they got it done carefully and without any damage to the walls or foundation.
The whole team was very professional, polite, and down-to-earth. Randall was responsive and helpful, and Zach was friendly and engaging with my very curious kids (and cats).
Highly recommend. My windows don't leak anymore, and my experience with the team was exceptional.

I absolutely love my new windows! This has been a great experience. Sammy's knowledge and understanding of E.E.R's products in service, made my decision easy. He was professional and friendly. I left the consultation with a complete confidence that my windows were going to be exactly what I. The price I could afford. Zach and the guy's showed up to install my windows. They were also professional, courteous and friendly. They took care to make sure that my house was kept clean and put back in order. They gave me full understanding of how to use and enjoy my new windows. I definitely recommend this locally owned company. Thanks so much Guy's!

Had a door replaced, Zach the installer, took his time to make sure it was perfect. Randall helped us pick out the door and made sure the price was good too.

Sammy was very professional, knowledgeable & punctual. He answered all of our question (which I'm sure wasn't easy given the circumstances) and didn't rush us. Zach & his crew were absolutely fantastic!! I especially loved the text Zach sent me after installation, stating that it was nice to work for Vern. That made Vern's day & made my heart beam.
Thanks to all of them
