    Eric did an outstanding job on the windows and siding on both of my houses! Everything turned out fantastic. What impressed me most was the quality of his work and how thoroughly he cleaned up when the job was finished. Everything looks great, and you can tell he takes pride in what he does. I couldn't be happier and would highly recommend window World of Delmarva to anyone looking for excellent workmanship! Tom, the supervisor was great on handling the whole project very professional. Everything went that’s planned couldn’t be happier. Thank You Norman Bechtel

    We are so happy with Window World of Delmarva. Everything went extremely smoothly with the reasonable estimate from Joe Bay, the installation of Windows and patio door from Tiago and Gavin, and the stain application on the windowsill from Robert Bay. They are the best!

    Window world did an amazing job with our warranty, the technician Robert was amazing. He made sure everything was working properly that I didn’t even know had issues. He called while on way, was prompt and efficient taking care of the replacement windows.

    I’ve had a great experience with Window World. First, they supported me with a warranty transfer when an issue came up with my windows (as a new homeowner, I hadn’t realized I could transfer the warranty and thought we’d have to pay to replace them). Then Robert, one of Window World’s service technicians, was fantastic. He called ahead to let me know when he’d be here, he was kind and respectful, replaced the two windows quickly, and went above and beyond — checking all the other windows under our warranty to make sure the same issue wasn’t on those as well. He showed me how to use the window block levers when I told him my concerns about my toddler unlocking/opening our second floor windows (I feel silly that I didn’t know they were there but so grateful that I do now!), and even fixed one window that was off-alignment. I’m very happy with Window World’s service, and I will definitely be keeping them in mind when the time comes to buy new windows for our home.

    I had Window World replace 7 of my windows. Amazing customer service keeping you updated on the status of the order. It took exactly the time they said and called when the windows came in and then were placed the next day. Tim and Kevin came and were amazing. They were very courteous and took great care in my house. The results were beautiful and I would highly recommend. My neighbors asked about how much I paid and were very surprised as they paid double with another competitor with one less window than I purchased. I’m very happy and already notice the improvement in noise. Looking forward to being cozy this winter!
