- RKroger kellerJul 6, 20265.0We recently ontracted Window World to replace the windows and sliding door in our home, and the entire experience was outstanding. Brent met with us to go over our needs and made several suggestions that we had not considered that made the selection process easy and resulted in the look we were trying to achieve. The replacement windows are very high quality, look durable, and visually made a real difference in the overall look of our house The crew, Earl, Jett and Scott, demonstrated excellent workmanship, fitting each window with precision and great care. The crew showed up promptly each day, worked efficiently and completed the quick installation ahead of schedule. Every technician was polite, respectful, and highly professional throughout the day.The crew maintained a neat work area and left absolutely no mess behind during cleanup. The lead installer conducted a thorough job-ending walk-through to ensure our complete satisfaction.I highly recommend Window World to anyone looking for stress-free home improvements and top-tier products.

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?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken.
