Frequently Asked Questions
Do I need waterproofing on a new build?
Yes, waterproofing is a critical step in any new build, especially in wet areas like bathrooms, laundries, kitchens, and balconies. Australian building codes require waterproofing to be done to strict standards to ensure long-term protection. Proper installation at the build stage helps avoid future problems like leaks, water damage or mould. Hiring a licensed professional ensures compliance and quality results from day one.
How do I check for waterproofing issues at home?
Some common signs of waterproofing issues include peeling paint, musty smells, visible mould, damp spots on walls or ceilings, and water stains. In bathrooms, you may also notice cracked or missing grout, soft flooring, or swelling skirting boards. If you see any of these signs, it’s worth having a professional assess your space. Early detection can help avoid more serious damage and costly repairs later on.
Is waterproofing permanent or does it need maintenance?
Waterproofing isn't completely permanent, but when done properly, it can last many years—sometimes up to 20 years or more depending on the product and conditions. Over time, joints may need resealing, membranes may wear, and new cracks may appear. Regular inspections and early maintenance can extend the life of your waterproofing and prevent small issues from becoming major problems.
