I am Joseph Guthrie, owner of 3G Builders and Renovation. I have always been interested in how homes are built. I started working in the residential construction industry doing flooring shortly after high school in 1998. I quickly graduated to more general construction. I started renovating homes for a profit in 2010. Through doing that I found that I also have a passion for business, as well as delivering a beautiful and high-quality finished product that homeowners love.

I decided to get my General Contractor’s license in 2020. Shortly after receiving it, I formed 3G Builders and Renovation. At 3G Builders and Renovation, we are primarily focused on residential remodels and renovations. After hiring so many contractors for my own residential improvement projects, I came to understand what is truly important in hiring a contractor. At 3G Builders we believe in treating every client’s home like it’s our home. Our reputation matters to us!

We believe in the importance of delivering the following to every client and every project:

  • We believe in showing up On-Time
  • We believe in maintaining Tidy Job Sites
  • We believe in taking the time to Do The Job Right
  • We believe in Sticking to Your Budget
  • We believe delivering nothing short of Excellent Quality
  • We believe in providing Frequent and Clear Communication
