We initially called R.A Interior Solutions for what seemed like a simple blocked sink in the basement. It quickly became clear that the issue was much more complex, involving a major blockage in the main stack affecting several sinks and urinals throughout the building. The team responded promptly and worked diligently over two days to identify and address the problem. They used specialist equipment, adapted to each challenge, and kept us informed throughout the process. Despite the complications, they remained professional and determined to restore functionality. We were impressed by their commitment and the thoroughness of their work. We would confidently recommend R.A Interior Solutions for any complex plumbing or drainage issues.
