Please, do not make the mistake of thinking that this is a Florida-Only issue. I lived in California for 49 of my 55 years and I can assure you it happens elsewhere all of the time.That is good, I'm happy to hear! I'll be honest, finding honest, hard working, caring contractors is very difficult here in Florida. It's very common for them to have drug and or alcohol problems, no show, like, cut corners, and prey on the elderly. This guy sounds like a good egg and I strongly encourage you to keep him around for you and your mother's sake.
That said, I completely agree, it's wonderful that she's found a reliable handyman. They are as unicorn as humble lead vocalists.
