"Excellent service, came when they said they would, very professional and honest, good price, clean and tidy, trustworthy, and above all helpful and knew their stuff. They gave reasons and suggestions for different methods and materials to save time and money where needed and never pretended to fix the unfixable. Would use them again in an instant."
