We had 19 windows replaced today. The professionalism was beyond amazing. They introduced themselves when they got here, told me the plan and got to it. They completed it in 1 day! Absolutely amazing. They cleaned up after and made sure everything was perfect. I cannot recommend Window World enough. From the start of getting a quote to the finished product. Highly highly recommend.

Yesterday we had 4 windows and a sliding patio door installed. After introducing themselves, they spread drop cloths through the whole house which we were impressed with. Their workmanship is impeccable. They were very professional and very courteous. They explained the operation of the windows and door. They completely cleaned their work area. Before leaving, they asked if we had any questions. We would highly recommend Window World. You will not be disappointed. Thank you.

We had 17 windows replaced, 9 of which were on the second floor. The crew that came out was incredible. They showed up at 8:30 and worked until 6:30 to get the job done in 1 day. Top quality windows, great price, awesome service. Cannot say enough good things about this company.

I would like to comment on my experience so far. The initial consultation was good, but needed to have a few things cleared up by the owner. I made an appointment with (Bill) the owner and got all the questions clearly answered. We asked about installation dates and were informed that December would most likely be the install time. I called on 12/13/24 and was informed that the install would be around the end of February or March. The person I talked to on the phone said they would put the file on top and let (Bill) the owner know. I have yet to hear from them. If I would have known that it would be almost 6 months to have my windows replaced, I probably would have second guessed my order/purchase at the time. I was looking forward to having my windows in December as was stated. Now it's too late for me to do a proper winter covering for my current windows. This is very disappointing as a customer that put 1/2 down on my order. I am now re-considering using Window World as an installer and canceling due to not getting answers in a timely fashion.
Frequently Asked Questions About Window World of Northwest Indiana
What does "Any Size, Installed" mean?
The term "Any Size" refers to any size replacement Double-Hung window our manufacturer will construct. Currently this is a minimum width and height of 15" X 26" and a maximum of 48" X 78". "Installed" refers to the removal of a basic Double-Hung wooden window and installing your new Window World replacement window, using the existing wooden stops.
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.
