What Our Clients Say About Us

Kevin P.

Very happy with my windows. I used this company to install replacement windows in my home in early December.

I worked with Steve. He was very clear about pricing and what would be involved in the window installation process.

All the new windows were installed in two days. Very good prices and a good experience. I would recommend this

Sandra K.

I purchased 6 windows and 2 sliding glass doors and the installation was timely and professional. Everything was completed in 1 day. I highly recommend AM Window & Door Solutions.

Josh T.

I didnt know much about windows, but Kevin made it easy for me to understand and select the right options for me.

Jim H.

Great Company, excellent quality product with the best installers in London. Have an older house and had AM replace all the windows in the house which I thought would be a challenge.

The windows were delivered on time, at an affordable price and installed by a professional crew. All the old windows were taken away. Everything was cleaned up.

Thomas C.

I took a ton of time before carefully choosing a window and door company to replace all the windows in my home. Thank you AM Windows for taking the time to explain everything thoroughly with zero pressure to buy. You truly get what you pay for when it comes to windows and doors. Major thanks to everyone at AM.
