He started in September 2020, said it would take 7 weeks, and I'm still waiting for him to finish (March 2021). Oak floor refinish was poor, tile backsplash is uneven, nails came up into the inside bottoms of my cabinets causing holes and he damaged new cabinets upon install (would not replace). I am giving 2 stars because I liked his painters.

In December of 2024 I paid $1000.00 to start bathroom project. I picked out my materials twice between then and April.
Corresponded with him maybe five times during that period. Everything he called it was a different reason for the lapse in phone calls. He offered $5000.00 at first then the total only if I would not report him.
That was June of 2024. Still waiting.
He business address is the post office on East Ave. He seems to prey on seniors be they single or couple.
