From Our Clients

“The Sanborns were GREAT to work with! They listened to our every need for our porch design and even made suggestions how to make other improvements in our landscaping to tie in with the new porch. Chris and Al have the knowledge, experience, and professionalism we expected from a business but also a warm friendliness that made their visits a much anticipated pleasure.” (M. & J. Pelchat)

“Al and Chris Sanborn were extremely professional and very knowledgeable. They were able to provide us with many creative solutions for our design problems and wishes regardless of some issues’ technical difficulties. We wish more projects could go as smoothly as this did, and we will recommend the Sanborns to anyone without hesitation..” (B. & C. Fessenden)
