I engaged Simon Randles to fix a leaking roof in June 2013. Of those who quoted he had investigated most thoroughly, and his quote was reasonable. He attended promptly, and sent me photos of what he did, which looked good. However, serious leaks appeared within 6 months. Despite giving a 5 year guarantee on his work, he has been unwilling to return to fix this, with excuses turning to impatience. Disappointed.
