R&J (Edinburgh Branch) did a basement tanking operation for us in a very timely and efficient manner. Prior to commencement, Malcolm, the surveyor, always made himself available to answer, sometimes complex, questions by email (usually same day to his enormous credit) which would warrant 5 stars alone. The installers (The “Dream Team”) of Jamie and Ryan also deserve a mention. Senior technician Jamie personally got through a mountain of work on the first day under extremely difficult and challenging conditions to ensure the job was finished well within time. Given the extent of the work the price was highly competitive. I would recommend without hesitation.
