Hannah, Tim, Amber, Rich and the whole team are incredible to work with. Everyone at Guardian Waterproofing is incredibly professional, yet you still experience the warmth and friendliness found with a family-run business such as this. Despite their growth and the scale of projects they work on now, it’s wonderful to see them maintain that personal touch and attention to detail. I couldn’t recommend their services highly enough!

I have been using Guardian for many years for my development companies, excellent to work with, very professional and happy to schedule the work around us. Also very good with aftercare and happy to liaise with properly owners if they perceive there may still be an issue although none of Guardians work has ever resulted in a problem.
