- BMBob MullenAug 6, 20265.0Mike Roy, from Window World met at my home to discuss replacement windows. Mike’s presentation was professional, friendly, and very relaxed! MIKE made it a point to make sure we knew every detail about the benefits of the windows and how to operate the Windows as well! Mike’s visit was professional and informative, and we appreciate the time you spent with us today. What was the special nice is that MIC did not require us to make a decision while he was at our home! Thank you, Mike Bob

- ELEdward LaVallieJul 6, 20265.0We met with a few different replacement window company sales representatives. Marco Ruiz and Window World won our business. Marco gave an informed and persuasive presentation, and demonstrated the quality and value of their products. He was a pleasure to interact with. I’ll update the review once the installation is completed.

What types of Payment methods & 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?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken. The type of window being installed and type being removed helps determine the amount of time needed to complete the job. On average each window takes about 30-60 minutes. Trim work and cleanup will require additional time to complete. An average job will take a single day.
