About Seal the Deal Waterproofing
This is a licensed waterproofing outfit covering Western Sydney and greater Sydney. Bathrooms, balconies and rooftops are the core jobs, with planter boxes, retaining walls and podiums in the mix too. They work across renovations, new builds, strata and commercial projects. The operator flags detailed preparation and membrane application as the part they do slowly, which is what keeps a waterproofing job from failing later. They also do remedial work, so they take on jobs where an earlier waterproofing attempt has let water through. Expect a sole trader setup, so you are likely dealing with the same person from quote to finish.
Best for: bathroom and balcony waterproofing in Western Sydney renovations, remedial jobs where an earlier membrane has failed, and strata or commercial waterproofing projects that need a licensed contractor.
