"Kyle was punctual, easy to work with, performed all tasks very well, and left each work area spotless when he was finished. This was a great experience!"

"He showed up to assess the job. We agreed on a price. He told me he was busy for a month so I waited. The day before the job he messaged me to send him more than half up front or he wasn?t coming. He never mentioned advanced payment. I said I wasn?t comfortable but would certainly pay him as agreed for the job. He told me he wasn?t coming if I didn?t send him money first. For a handyman? Leave me waiting for a month then demand payment up front before doing one minute of work? Totally unprofessional!!! Time waster!"
