Waterproofing for every part of your home

Your rights under NSW law

Residential building work in NSW is covered by statutory warranties under the Home Building Act 1989 — generally six years for major defects and two years for other defects. On top of these protections, we provide our own written workmanship warranty and product information on every job.
