- TPTroy PostlerJan 14, 20261.0Do not buy from window world. They said 4 to 6 weeks to get the window. It showed up 4 months later, with caulk on the inside of the window and I can't get them to replace it. Said they were going to replace it made a appointment and they never showed. So now iam stuck with a picture window full of caulk.
- PMpaul missettDec 15, 20255.0The workers were friendly and courteous. It was great to get to know them .They took care of each window as if it were their own .we would definitely hire them again and recommend them highly .Paul and Sue
- SKShelley KageSep 11, 20255.0We are super happy with Window World and highly recommend and we will use again also!!
- CRCari ReynoldsAug 10, 20255.0Window World has been great to work with. After getting estimates from several companies, I had them replace 7 windows last summer. They did such an amazing job, I had them come back to replace 4 more this year. The entire process was smooth with great communication from start to finish. Very professional installation and the windows look amazing. I would definitely recommend them for any home exterior projects!
- BKBill KubisiakJun 16, 20213.0We hired them to complete a job for us Windows are fine. The cleanup was horrible. We paid for lead paint cleanup. Lead safe practices were not done. Paint chips everywhere. I don't think plastic was even used inside or out. We had to clean up after them with wet wipes and HEPA vacuum. This company will get some one sick from lead!!!!! We have to pass a lead clearance test on each window. We did pass. Only after hours of cleaning up their mess. If you don't care if you or your kids get sick, go ahead and give them a call.
Frequently Asked Questions About Window World of Wausau
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.
