We bought our windows about five years ago through LEI in Madison. They are great to work with! Very professional & courteous! They answered any questions we had! We highly recommend LEI to anyone who’s looking for new windows or patio doors! My husband & cat love our bow window that was put in!

LEI offered great pricing and great product. Our sales person, Mark Levandoski, was great, and very on top of things during the whole process. Our installer, Steve, did a great job and explained the process and how to work the windows upon completion, and, no clean up for me after install either! Our cream windows with cream trim look fabulous. What more can you ask for?!

Tiffany Lancaster, - Madison, Wisconsin

Greatly improved my home value and love that warranty was transferable to new owners when I sold. Like the safety features so I could open but still “lock” for my fresh air.

Cheryl Levandoski, - Madison, Wisconsin

Great service!! Would definitely recommend for friends and family!

Tracie Keebler, - Madison, Wisconsin

I typically find any type of home improvement extremely stressful, and I’m particular about the quality of work being received. From first contact I felt confident that the job was going to go great! Communication with LEI Home Enhancements of Madison was amazing. Scheduling, as well as the job itself, went so smoothly leaving me with such peace of mind. I wholeheartedly recommend this company and their services.

Salesperson is a superb agent that does everything he can to meet and far exceed the customer’s expectations. I’m recommending him to all friends and family!

Tex Niedringhaus, - Madison, Wisconsin

My husband and I were referred to LEI from a friend, and I will admit we were skeptical at first. Our friend had the windows installed on his house, and I got to play around with them. From the first intro to the installation, we were really impressed! Our installer answered all of our questions and was so efficient! We’ve had so many compliments on our windows. They’re super easy to use and clean too!

Galina E., - Madison, Wisconsin

When we bought our house the windows were original from the 80’s. We had to put plastic over them and there was still a draft! These windows make a huge difference. We’ve already noticed a decrease in our gas and electric bill for this year.

Sansone J., - Madison, Wisconsin

We did have a little manufacturer defect on one of our sashes, but the customer service representatives were quick to get new ones on order and installed right away. Our windows were original to the house, and let me tell you these are AMAZING! I will definitely refer my friends and family to LEI. Thank you all for being so fabulous!
