- JOJames Ohliger4 days ago5.0Matt at Window World Twin Ports was fantastic to work with. At every step of the process, he went above and beyond to make sure we understood our options and ensured we were going to be delighted with the finished product. Communication throughout the project was top notch, which is rare to find these days. The slider doors on our home look great and Matt personally came by to clean and shine each one when all of the work was done! I can't recommend Window World Twin Ports enough.
- JHJoni HemmingJun 1, 20265.0We recently had new front picture windows installed by Window World, with double-hung windows on either side, and we are absolutely delighted with the results. What stood out most to me was how well cared for I felt throughout every phase of the process. From the initial consultation to the final installation, everyone was friendly, professional, and genuinely interested in making sure we were happy. Questions were answered promptly, communication was excellent, and everything went smoothly from start to finish. The new windows have completely changed the appearance of the front of our home. The picture windows bring in so much natural light and provide a beautiful view, while the double-hung windows on either side are both attractive and practical. The installation crew was outstanding. They worked efficiently, paid attention to detail, and left everything neat and clean when the job was finished. Purchasing new windows is a significant investment, and Window World made the entire experience a positive one. We are extremely pleased with the quality of the windows and the service we received. I would not hesitate to recommend Window World to family, friends, and anyone looking to improve their home. Thank you, William

- CLConor LundMay 14, 20265.0Window world has been amazing to work with! We got a quote from them and they replaced all of our windows in only one day! Then because their team was so great to work with we ordered a door from them. I was able to get any color of door I wanted and it is the most beautiful pink door! Would recommend Sarah, Matt, Jeff and their team to anyone.
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.
