- RKR Keplinger4 days ago5.0Needed a window dealt with under warranty claim. Warranty was easily honored - no hassle at all. Very knowledgeable tech came to the house dealt with the issue. Exactly how you'd expect a Warranty claim to go. Thanks Robert!
- ESEmily Scott6 days ago5.0David and Rob from Window World just fixed and adjusted windows in my condo that were installed in March. Initial installation was a mess. This dream team patiently listened to my concerns and addressed each one. They also guaranteed to come back and readdress any issues that were not fixed to my satisfaction. Excellent job, David and Rob!!!
- JPjohn pintoJun 29, 20265.0Robert came to my house to fix the squeak in my sliding glass door and went above and beyond the door is perfect, and he even tightened a door knob for me, such a friendly and professional young man.
- MWMarji WestJun 25, 20265.0Robert is the best, he replaced 2 windows that had lost the seal. What a wonderful gentleman, punctual and checked all the other windows to make all good! Could not be happier, makes me happy we chose Window World ðð»
- BMBeverly MumfordJun 12, 20265.0We had to replace a long window in our living room that took a little more time than just popping in a new one. Robert the serviceman did a fantastic job of replacing it. He explained what he would do and how long it would probably take. He was very courteous and he cleaned up everything. Due to the warranty it didn't cost us. Thanks Window World.
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 manufacturerâs 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.
