This was a project a customer had started, but quickly realised it was more than he could do. When this bathroom was installed, it was a poor insulation, not sealed correctly and started leaking after a few weeks, many years later, the damage was done. After pulling up the floor and removing the walls, the evidence was clear to see. Remove all the rotten walls, stud work and flooring. Fit new and start again. This is the end result, another pleased customer.
