Adam is a fantastic communicator and incredible efficient. He is punctual, true to his word and an expert at what he does. He’s also very trustworthy and honest. I had major leaking issues in my shower which affected the adjoining wall and he pulled back the tiles, removed all cement and waterproofed the area, added original tiles and grouted the area as well as waterproofing the walls of the shower with spray.

I am a plumber and I need a waterproofer for one of my jobs in Springwood will need you to come quote • Waterproofing work in the downstairs bathroom and upstairs bathroom—there’s evidence of failure and water staining beneath both. • Laundry installation—we’re keen to get this sorted as part of the wet area works. • Drainage and subfloor moisture—there’s pooling and staining under the house, especially near the bathroom. We’d love your advice on surface water runoff and plumbing leaks. Don’t have photos I will also go up on Saturday aswell to have a look myself I have done a job for them before in a different house very nice people
