Customer Testimonials

“John and his team did an exceptional job renovating the third floor of our home. It turned out exactly as it had been designed and when I had small design changes it was handled perfectly. We would highly recommend his services – especially to anyone with an older home that needs renovation!”

— Shelly R

“John and his team are GREAT to work with! They make sure the job is done with quality and craftsmanship. This particular recent project included the replacement of our aging shed doors, the removal and replacement of our garage doors trim work (original framing was deteriorated at the bottom) as well closing the open space atop our Gazebo. Thanks John!”

Great Deck and great service!

— Noelle S

We have worked with Kauffman builders for more than 10 years. They have finished our basement, done remediation and stucco replacement work, rebuilt our trex deck after the initial contractor did poor work, built a pantry and many small projects such as new closets and painting. They do great quality work, are reasonably priced and always are on time. Any future projects that we have will certainly be done by Kauffman
