Very quick response to my initial post although identifying the probable source of the leak took some time. After I accepted their quotation for remediation there was quite a wait for the bathroom team to become available. When work started the team were knowledgeable, explaining the various issues that they encountered and offering sensible solutions. The work was finished in 2 days and everything was left clean and tidy. I thoroughly recommend this company.

With over 40 years combined experience in the building trade our company has grown and build an amazing portfolio of jobs and customer clientele.
