Robert & Sons just finished painting the inside of our house. Our experience has been great in every respect:
Reasonable pricing, clear on scope of work
Very responsive
Excellent Quality -- incredibly short punch list
Kept house neat -- did a great job removing dust after prep and sanding
This is the second time Robert & Sons has worked on our house -- they painted the outside of our house 22 years ago. That paint job held up particularly well, and we are only now having to repaint it. Robert & Son will do that work too.
