I am John Salmons, the host of Takeoff Tech and a residential construction estimator serving home builders and lumber companies since 1994 dba Construction Research Group.
For the ten years prior to becoming a professional estimator, I swung a hammer installing almost everything I estimate today. During this time as a home builder and remodeler, I found myself strapping on the tool belt and framing most of my projects. I also installed my own roofing, drywall, interior trim and just about everything else that I could get my hands on. Having this hands-on field experience allows me to truly understand building materials and how to accurately estimate each of them today.
My mission for this site is simple: To share my passion for estimating, the takeoff software I use to earn a living and my skills that I'm continually improving.
