The majority of our damp proofing work involves dealing with issues in clients’ homes. We guide private and commercial clients through a process of inspection, following a report in which we diagnose and provide timely schedules of repair work where necessary. Our aim this is to provide value to clients through the quality of our work, professional correspondence and workmanship.


Although our sumps and pumps are very robust and reliable, we offer our clients an annual pump service to ensure that our system is working effectively and that this equipment is fully functioning and capable of discharging water when required, which is essential to protect your basement. Our trained pump installation and maintenance technicians will inspect all aspects of your pumping set up, including pump condition for signs of corrosion or damage, the free movement of activation floats, check valves, power supply and alarm panels etc.


All our technicians have been fully trained and certified to offer our clients peace mind when looking to undertake basement cellar conversions, and waterproofing installations. The conversion of any basement into a dry habitable room must be designed by a waterproofing specialist, to take full responsibility for the design and liability of the project and also to be covered by long-term guarantees for total peace of mind.

We are accredited by the Basement Waterproofing Association (BWA), which is a trade body that represents manufacturers, suppliers and installers of below-ground waterproofing products, which are all designed to protect below ground structures from the ingress of water.
