The crew arrived on time. They knew what they were doing. The Okna windows are wonderful and have some great features. I love that they open into the room so you can easily wash them without having to climb a ladder, lock on partially opened window and half screen. The job done by the crew was excellent and they cleaned after themselves and took away the old windows.

Young and his team did an Outstanding job!! They were courteous and very professional. As a retired military guy, I appreciated their attention to details. It's also nice to support a veteran owned business... When my wife came home from work and said, "The windows are beautiful and I LOVE the sliding glass door!!" Husbands know... MISSION ACCOMPLISHED!!

Joon and his crew replaced all the windows and a door in our house. They showed up on time all three days of the project, were efficient, and the window and door installation looks professional inside and outside. I will happily recommend them to other people I know who are looking for replacement window company recommendations.

Description of Work: They put in new windows for us. Our experience was fine. They provided great quality but were a little expensive.

Thanks for the feedback. We hope that you feel that the Quality product and installation you got was still a value at the price for your project. The windows that you did get in this case are the best vinyl windows on the market and had quite a few expensive options (Simulated divided lite, custom color) that do add to the overall price of the unit.
