- SLSteph LoveMar 3, 20265.0I had my front and back entry doors replaced in December, as well as two windows in my sunroom. The entire process, from getting a quote, to the installation, was seamless. The Window World team is easy to work with, answered all of my questions, and did a phenomenal job with the install. The windows and doors are high quality, and look amazing. There were tons of choices for customization, and the doors and windows fit the character and time period of my 1922 house. They were also affordable, with a number of financing options to make it even easier. I'm looking forward to having them back when I need additional work done at my cabin. I cannot recommend Matt and his incredible team at Window World enough!
- RHRich HoughtonFeb 17, 20265.0We had 4 windows replaced and new 6000 series insulated vinyl siding in harbor blue. They were fast, efficient and took care to replace rotten board areas. They were great with communication on any issues or to answer questions. Would highly recommend Window World!
- TET EJan 12, 20265.0Matt and the Window World crew did a great job! I had windows, an entry door, and sliding door replaced. Their price was very competitive! The final job looks fantastic, came in at the quoted price, and they completed the job in a timely manner. I would highly recommend Window World Twin Ports!
- PDpam dearbornJan 6, 20265.0It was a smooth process from start to finish. The installers were very professional. The windows arrived quickly once ordered. I highly recommend Matt and Window World.
- NPNathan PetersonDec 19, 20255.0I had a great experience with window world! I have an older house with older windows. I needed 2 replaced. Matt came out and told me that it would be no big deal to change the windows. The technician Jeff came out and removed the old windows and installed the new windows in a couple hours. Matt was great to work with and Jeff was a master at installing the windows. I am so happy about how the whole project turned out. I would recommend window world to anyone looking for window replacement.
Frequently Asked Questions About Window World Twin Ports Region
What types of payment methods and financing do you offer?
We offer a variety of payment methods and financing options depending on promotional period. Please contact us for more information regarding available options. Financing is subject to credit approval.
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.
