John has a business degree and he takes pride in his professionalism, customer service and his overall cost savings approach without sacrificing quality. John personally oversees each and every project.



John Dean built our home in Windham, New Hampshire in a beautiful neighborhood, Winslow Lane. 

In our search for a builder for our first home in nearly 25 years – we were looking for someone that we had confidence in and that had the craftsmanship and technical ability that would translate into a home that we would love and our friends and family would appreciate. 

With John Dean we were so fortunate because we received much more than we had hoped for in the building of this home. The most valuable characteristics of John Dean include the following: 

Attention to detail, Trustworthy, Honest, Hardworking, On Time and Craftsman!

Bottom line, I would recommend John Dean and Spring Mountain Builders without any reservations.
