Building Practices

Quality Construction Features

We want you to know some important facts about a Kathcon-built estate home that make a true difference in the lasting value of your investment. While some builders choose not to disclose their building practices we feel it is important that you have all the necessary information as to what features are inside the walls, floors, and ceilings of your new home, beyond the attractive exteriors.

Kathcon specifies the following in every home:

  • 2×6 wood studs for exterior walls
  • Whole-house plywood wrap
  • 5/8″ drywall for all walls and ceilings throughout, glued and screwed
  • 3/4″ tongue and groove plywood sub-flooring on T.J.I. “silent floor” joist systems

Energy efficient insulation

  • Brand name HVAC equipment and appliances
  • 4″ concrete basement floor slab with fiber mesh reinforcing
  • Structural steel support
  • Continuous drainage tile: Inside and outside foundation
  • R-38 attic insulation

We are a company that demands superior quality and expert construction practices.
Our commitment to you is to build a custom home that will exceed your expectations in every way.

Thomas Miller

Custom Home Specialist, REALTOR®

Tom’s love for building started at age six, riding along with his dad and later cleaning and grading job sites. During college he kept his hands busy working in masonry and carpentry. Three years after graduating with a degree in Finance, he became a full-fledged partner with Kathcon and since has been cited for numerous outstanding sales performances including: 4 top-producer awards, the largest sale in company history, multiple million-dollar years and numerous gator hunter trophies. Recently, Tom has been instrumental in the disposition of non-performing assets, and repositioning Kathcon for today’s challenges.
