- RFRyan Fitzpatrick4 days ago5.0So far we have had over 10 windows replaced and 6 more coming up. We also had a faulty top sash that needed replaced. All happened without any issues or concerned. Very simple process working with window world and have had a great experience so far! Planning for more windows in 2027.

- GAghazala aliOct 18, 20264.0Be careful how your contract with finance company is set up—not as clear as the salesperson makes it sound. Be sure to check the duration of the interest-free financing agreement.
- DSDan SmithOct 13, 20265.0Adam came out to address a warranty issue and was on time, very professional, and as an added bonus he fixed my issue in one short visit. Very happy with Window world today.
Frequently Asked Questions About Window World of Frederick County

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.

It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
