We hired Mason to help renovate our small bathroom. He helped us by laying new flooring, replacing our toilet / vanity, and installing new fixtures. I have nothing but great things to say about the work he did. Mason was always timely, considerate, and paid close attention to the details. When we discovered that more work needed to be done, he was very transparent on what the additional cost would be & how long it would take. We will be scheduling all home maintenance & repairs with Mason moving forward. Thank you again, Mason!
