Legacy installed our windows and we noticed an immediate difference in temperature inside our home. The windows are high quality and easy to use. Their entire team, from sales to admin to the install team were professional and easy to work with. For such a big purchase my wife and I were completely comfortable working with Legacy. We love our windows!

They make the planning and ordering process simple. The day of installation went smoothly and quick! And most importantly, the finished product turned out perfect! We love the way they look, the neat different window features, and we’ve already noticed a big improvement in temperature regulation and sound insulation. We would 100% recommend Legacy Window to anyone looking to improve their window quality, energy efficiency, and curb appeal!

Jessica Warren

Great experience! They kept me informed all the way from order to installation. Their Installation crew quick, had quality work and left everything clean. High recommendation for the whole process and high quality windows. Windows are very easy to clean and drastically reduced the noise from the outside which we were very happy about! Had the majority of the houses replaced in one go and they had arrived and completed the work all in one day.

Thomas Battelberghe

We are VERY HAPPY with the experience we just had with Legacy Windows. From the demo to custom window making, to the installation today, it took about 2 and a half months for everything! Which, if you know anything about window installation is pretty quick! They cleaned up after themselves, they explained the whole process, and even let us know when a problem arose. Which they also took care of as well!

Heather Tiffany

We are super excited with our new windows! The install crew was speedy and professional. The communication that legacy windows provides is clear and concise and never left us wondering what was happening. 10/10 would recommend if you are looking to upgrade the look of your house.

Tanner Buchanan

Legacy Windows did an excellent job from start to finish, we are very happy with our new windows. The Crews showed up promptly and were respectful and friendly, taking care not to track in dirt and snow, cleaning multiple times during the installation. The windows are high quality, beautiful, and functional. I’d recommend Legacy to anyone looking to upgrade windows.

Rosie Erni

Our experience with Legacy has been amazing from the sale to installation. Our sales rep went over everything with us. He was extremely knowledgeable about our options but not pushy at all. He detailed what we should expect throughout the process and was spot on. The installers were extremely professional, fast, and cleaned up after they were finished. Our windows look great and we are very pleased with the outcome.

R. M.

Loved working with the whole team! From our sales rep all the way down to our installers! The process itself we were estimated closer to the end of the year for the custom sizes we needed, but they got them done way sooner! We loved that because it was about time to turn the furnace on and the front of our house is the coldest during fall and winter months! We love our windows!

Katie Heninger

After replacing a majority of the windows in our home, I highly recommend Legacy Windows. They were great to deal with, and I am very impressed with the end result. The install was super quick, and the installers were very friendly and professional. The new windows are very easy to clean and help significantly with noise reduction. I have included a before and after picture of one of our windows and a picture of the front of our home after replacing the windows. Such an improvement!
