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!
Frequently Asked Questions About Window World of Delmarva
What types of payment methods and financing do you offer?
We offer a variety of payment methods and financing options (subject to approved credit) depending on promotional period. Please contact us for more information regarding available options.
Will the replacement windows be installed from the inside or outside?
The majority of our replacement windows are installed from the outside. In some situations it may be necessary to install from the inside. On the day of installation, your installation expert will assess your unique situation and explain the process that will best suit your home.
Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?
Window World installs replacement windows year-round. An average installation will take only one day. Our crews install one window at a time and are trained to do what they can to minimize heating/cooling loss. The energy savings from your new windows will recover any incremental energy costs incurred during their installation many times over during their lifetime.
How can I prepare my house for my replacement windows?
Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company. Please provide our installation expert with a clear path to the window(s) being replaced by moving anything that may be in the way. It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
How long will it take to get my replacement windows? How much time should I allow for the installation?
Since every window ordered is custom-built to fit your home and design choices, manufacturing times vary. Once delivered, the type of window being installed and the type being removed help determine the amount of time needed to complete the job. On average, each window takes about 30 minutes. Trim work and cleanup will require additional time to complete. An average job will take a single day.
What type of warranty is available for my windows?
All windows and patio doors we sell come with a manufacturer’s lifetime limited warranty and a repair labor guarantee, good for as long as you own your home! Contact us or see our warranties page for more details.
What happens to my old windows?
After installing your new replacement windows we remove all old windows from your property and dispose of them properly. If you wish to keep your old windows or storm windows, please notify the installation crew as soon as it arrives for your installation.
What do I do if there is a problem with the windows?
Most of the issues encountered by our customers are easily corrected and don't necessarily mean that there is a problem with your window. You are always welcome to contact us for help.
