I purchased a home with the stipulation of 2 windows to be replaced. The windows and services have been paid for. I have been waiting now for 3 weeks to have them installed. They keep canceling the appointments or they are scheduled and have just not shown up!!! So it's getting closer to winter and here we sit!!! Very disappointed and frustrated!!! I keep reaching out to Jeff the GM. Mailbox is full on his voicemail and not answering my text message. Today they were supposed to be here at 10am to install and nobody here, nobody has reached out to me!!! I am beyond dissatisfied!!!

We had the best experience . From sales to installation, everything was smooth, fast, efficient and extremely professional. James and Jacob did a marvelous job installing our windows while we both worked from home. We will recommend this company to anyone.

Frequently Asked Questions About Window World of Sioux Falls

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.
