Why Your Neighbors Trust Us

Our satisfied customers say it best and keep coming back. Over 50% of our business comes from referrals and returning customers like you.

Gave us great suggestions on window replacements. We love the picture windows and other suggestions he made. He is very knowledgeable and came to our house during the installation to make sure all was going well and we were happy with the windows and installation.

The installers were very skilled and knowledgeable. In my Family Room, the installer even took it upon himself to level the wood shelf under the window he was installing so the wood framing the window would be even and “look nice“ as he said. He didn’t have to put in that extra effort, but he did…he took great pride in his work.

Next Door & Window worked within my schedule and timelines. They are very professional. And Scott the salesperson inspected the installers work to make sure they were doing what they were supposed to. I have nothing bad to say about them.

Very professional, I enjoyed visiting the showroom and being showed around the shop to see how they prepare the windows for installation, and of course meeting those who run the show!

Next Door & Window is a breeze to work with! The sales rep in Madison is very professional and knowledgeable on the product they carry, while not being so pushy like other companies. Would highly recommend this company to anyone searching for quality doors or windows that want the job done right.

Next Door and Window did an excellent job in the delivery and installation of our new sliding glass patio door. It adds an entirely new dimension to our home. The installer was prompt, efficient, courteous, and meticulous. We couldn't have made a better choice in the product or the company. I highly recommend them.

From the salesman to the installers we have had an excellent experience! We had our house windows and doors replaced in three phases. Each time the professional workmanship was outstanding. By the time they were finished each time, everything was clean and as if the doors and windows were always there.
