About WaterproofSG

WaterproofSG Pte Ltd holds a perfect 5.0 Google rating across 198 reviews from their Kovan base, one of the strongest combinations of rating and volume in this category. The firm specialises in leak detection and waterproofing for roofs, walls, and bathrooms, with a strong residential focus. Their diagnostic process involves thermal imaging and moisture mapping to locate the exact source of water ingress before recommending a repair path, a step most contractors skip entirely. Reviews consistently highlight the speed of assessments, typically within 2–3 business days of enquiry, and the accuracy of their diagnoses. Services cover simple roof sealant patches through to full polyurethane membrane applications on flat commercial roofs. WaterproofSG's precision-first approach makes them particularly strong for complex or recurring leaks where previous contractors have repeatedly failed to identify the true source.

Customer Review

"WaterproofSG found a leak in our roof within 45 minutes using thermal imaging that three other contractors had missed entirely. The repair was done the next day and they followed up two weeks later to confirm it was holding."
