Why We Should Be Your Custom Home Builder for Green Building

Your Satisfaction is Our Primary Concern

Jon Tuthill Construction is a closely held company which allows us to keep complete control of all aspects of the construction process. We strive to make the building process enjoyable and persona for youl. Our highest concern is your satisfaction with our work. Our personal approach to building stresses constant communication between client and builder from start to finish. This is essential to deliver the best possible product to meet your individual needs and build lasting working relationships.

JTC uses customized software to meet our client’s individual needs. JTC has developed a very effective process for keeping you informed and involved in your project.

Out-of-town owners - Jon Tuthill Construction has constructed many homes for absentee owners and understands the difficulties involved.  We have had owners who never visited the house until it was completed.  Our unique management methods allow clients to stay up to date on the progress of their house from anywhere in the world.  It also allows close communication between client and builder to make timely decisions on elements which require owner input.

We follow the principles of Building Biology (building science)

What is Building Biology? In a nutshell, it is the study of how buildings and people interact. Building Biologists have studied the relationship between the built environment and health and apply this knowledge to create healthy living and work spaces. We approach the building process as a science and understand the physics at work in a building- the way air, water and heat move through a structure and how it ultimately impacts the building's occupants. This understanding is critical to the construction of a well built, comfortable, and healthy building for you.
