- ONOlivia Northcraft5 days ago5.0Adam is wonderful! Whenever we have needed a sash replaced it has always been easy and we are always fully satisfied. We are reassured that our windows are always covered!
- CCChristine CApr 1, 20265.0Excellent service follow up!! Had an issue with the lock on our sliding glass door and they came right out and fixed it. Easy fix but I never would have figured it out. Nice guys!
- CHChes HillMar 23, 20265.0Adam, the Service Tech is great! One of my new windows was not locking and when I called the Frederick office I was able to speak with him right away. We are at least a half hour drive away and he was here in about an hour! A minor issue we had getting our install setup was quickly resolved by Caprice, the Frederick office Manager. Would recommend Window World to anyone! Lawrence
- TBTanya BeardenMar 19, 20265.0Excellent experience with Window World of Frederick County replacing our old windows which we have had for 13 years. I called and spoke with Caprice regarding a service inspection and she had the Service Inspector Adam respond same day. The Service inspector Adam, was professional, arrived on time, and took great care to ensure everything was properly inspected. Our Windows and doors still look amazing over the years. Adam, will be taking care of replacing a few windows and will look forward to the install. Highly recommend! Thank you!
- TFTerry FawleyMar 17, 20265.0Great company to do business with. Cordial, accommodating and excellent at what they do. I had all my windows replaced by Window World of Frederick in 2017 and they are still in business and still honoring their warranty. The person they sent was very professional and took care of the problem (a problem caused by me when cleaning the windows). I would highly recommend using their services.
Frequently Asked Questions About Window World of Frederick County
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?
