- ACanthony corigliano2 days ago5.0Window World of Buffalo did an excellent job for our business. Their team was professional, efficient, and easy to work with from start to finish. Communication was clear, scheduling was smooth, and the installation was done right the first time. The quality of the windows and workmanship exceeded expectations, and the project was completed on time without disrupting our operations. It’s refreshing to work with a company that delivers exactly what they promise. Very satisfied and would gladly work with them again.
- JDJoseph DiBiaseMar 7, 20265.0Window World was fantastic they removed our very old crank windows, put in new frames and had the new windows all installed in one day, and a winter day at that. Windows were custom made exactly how we wanted them. Would 10/10 recommend.
- JHJohn HawkinsMar 5, 20265.0From the quote to the order process to the install went just as advertised and they coordinated with our HOA to obtain approval. The install, in the middle of winter, was executed without delay or issue in about 4 hours at most. And this is not the first time Window World has delivered on time and on budget for us on several of our properties. Well done and thank you!!
- JFJoe FlossMar 4, 20265.0Nick and his team were great to work with. We bought an older house in Newfane and none of the windows worked properly. They installed new windows for the entire house in one day. Great value, great service and the installers were respectful and cleaned up. Extremely happy with the product and the experience in dealing with window world.
- DDDaniel DiPofiMar 2, 20265.0I renently had Window World replace all of the windows at my daughters home. I replaced 30 year old Anderson casement windows with sliders. The windows look fantastic! I was originally worried that "replacement windows" would not look original to the house - I was pleasently suprised. I would recomend Window World to anyone. The process was easy and the whole team was great. From the folks that came to measure and explain the process to the installers. Installation only took one day. The guys were friendly and when they were done, the house was cleaner than when they arrived.
Frequently Asked Questions About Window World of Buffalo
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.
