Absolutely the worst customer service I have ever experienced. I have spent over a year and a half trying to get them to fix a defect. Avoid at all cost.

Very displeased. I this makes 15 windows i have had installed from window world. They call the day before to see if they can come they had called like 3 different times to come out but due to i pick my grandkids up i couldnt do it. They called dec 15 and wanted to come. I felt obligated to change my schedule so they could come. I told the guy it had to be in the morning. He said u can have any time nothing is scheduled. I called you first. I cancelled my granddaughters dr appointment and missed a funeral i should have been at. The installers decided to go to a different one before me and to do mine last that day. At 230pm we left and we passed them on the road bc we had to leave to pick up my granddaughters which i told them i had to do. The owner called me 3 weeks later to only tell me yep it was our fault but i have no intentions in compensating you for being charged for cancelling a dr appointment you need to pay what the contract says. I have 3 more windows and a french door needing replaced but it will not be by window world. Not worried about loyal customers just want ur money dont care if they r in the wrong or not. Jason dont know how to deal with people apparently. Told me my dad dont know how to do business bc he had a business for 49 yrs and if he was in the wrong he compensated them he said i am not in business to do that even if we are in the wrong.

Frequently Asked Questions About Window World of London
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.
What type of warranty is available for my windows?
All windows and patio doors we sell come with a manufacturer’s lifetime limited warranty and a repair labor guarantee, good for as long as you own your home! Contact us or see our warranties page for more details.
What happens to my old windows?
After installing your new replacement windows we remove all old windows from your property and dispose of them properly. If you wish to keep your old windows or storm windows, please notify the installation crew as soon as it arrives for your installation.
What do I do if there is a problem with the windows?
Most of the issues encountered by our customers are easily corrected and don't necessarily mean that there is a problem with your window. You are always welcome to contact us for help.

Window World of London accepts cash, check, and financing options (subject to approved credit). Contact them for current financing promotions.

Are replacement windows available year-round, and will installation affect my home's temperature?
Yes, installation is done year-round. Crews work window by window to minimize heat/cooling loss, and energy savings from new windows outweigh any temporary costs.
How should I prepare my home for window installation?
Remove curtains, blinds, window treatments, and wall decorations near windows. Security sensors should be turned off by your security company, and pathways cleared for installers.
