“We just wanted to let you know how pleased we are with the work that Keystone Custom Decks did in transforming our outdoor patio. From the initial consultation with Ron Yoder to the final build, the entire process went smoothly. Matt Blank and his crew were the best!”

“Not only did Mahlon help us design exactly what we wanted (with super-helpful 3D renderings), he created exactly what we wanted. He and his 2 teammates were here bright and early and worked SO FAST. They were kind and respectful, which was especially important given that I’m home with my young kids who love to watch and ask questions.”

– Andrea R.

icon – quote

“We had a difficult site with steep slopes and Mahlon and his crew did an amazing job of minimizing the disturbance and working with the grade. The decks (two separate decks) are beautiful and just when I was sure they were done with an area, they added more trim, more detailed finishing work. The final product is just so wonderful!”
