Chris and John and crew were hard working and brilliant. They turned up on time and made light work of putting in double steels making sure everything was done. When building control requested added work, they had no problems getting it sorted. Hard working team cleaned up each evening. Great job. Price was reasonable.

Revised review. I originally gave a 1 star review to Bill Osborne(RL Contracts)for the substandard work that he undertook solely. He told me that this review had to be removed for me to receive a partial refund. Which I did. To finish the extension, I have retained the sub contractors that he originally employed as their work has been exemplary. I have spent the past month repeating work that he undertook personally (roofing/plumbing) and am massively out of pocket even with a refund. HENCE THE ONE STAR
