Exceptional Craftsmanship and Communication from Start to Finish

We hired Kraft to build a full bathroom in our basement of our 1941 home--and this was the best decision we could have made for the project.

Quality Materials, Skilled Repairs, and a Pergola We Finally Love

We recently had our pergola replaced but unfortunately the company we hired left us with a complete mess of a job. The large columns, which are really the focus point were re-created using flimsy boards which apparently weren't attached properly and within a couple of weeks the boards and panels were coming apart. We called Kraft and worked with...

Exceptional Communication and Craftsmanship from a Seasoned Homeowner’s Perspectiv

Having built 3 houses and remodeled 5 or 6, clear communication and prompt follow up are key to a successful project. Kraft demonstrated these qualities right from the start.
