Hard Flooring- 12 Jun 2026
David did a great job at one of our projects. The client was really happy with her new flooring and praised David for how clean and tidy he was, for helping her move the furniture and for the extra hours he spent making sure everything was done in a day. We would definitely recommend and use David's services again.
