Check out these comments from a local homeowner!

This team and company is so great to work with! They made everything easy and were transparent about the process the entire time. We replaced 15 windows in our house with them. Because of supply chain challenges installation was delayed but they were transparent about it up front and kept us updated as we waiting for our order to come in. During installation the crew was very professional, they worked well together, and they kept things very clean and neat as they went along. They covered our furniture from dust, vacuumed, and repaired/touched up everything they worked with to make it look great with our paint and exterior. The installer was meticulous, walked us through how to maintain and clean them, and we were very grateful for the whole experience. The sound difference and visibility are incredibly noticeable in the vinyl windows we selected too. We were very happy with this company’s professionalism and integrity.”

  • Avatar Elaine Werner ★★★★★ in the last week
    Top notch company - install of entire home's windows went perfectly and the price was … More very reasonable compared to other companies.
    Installers were very respectful of our home and did an excellent job. Just went through a hurricane of 64 mph winds and the windows did just fine.
    Loved how they cleaned up so well after the install - no trash or debris left lying around.
    Just all around great experience dealing with these guys!

    Buying windows from Aimee at Replacement Windows of Katy has been a great experience! We have … More had other windows replaced in the past, and I sure wish I had known about Aimee and RWOK back then. The windows are beautiful and the time it took to get them was very reasonable. Their installation crew was also fantastic, very professional, and did a beautiful job. 100% satisfied!

    I worked with 4 different vendors before selection RWOK. Why did I choose RWOK? They were by … More far the most responsive. I got quick quotes and answers to my questions over email, and they used SMS to schedule the install and ensure we were all well informed of the project (which I managed remotely to boot - I live in a different city than my mom). Their prices were good, and they installed 11 windows and 2 sliding doors in just one day (they had a 5 person crew) and my mom was happy with their service and work.
