Who We Are

Established in 2016, Coastwide Waterproofing was built on a simple principle—do the job right the first time. Based on the Central Coast, we service the region and extend to North Sydney areas such as Hornsby and Narrabeen.

We bring hands-on knowledge and a straightforward approach to every project. Our team works with homeowners, builders and property managers to deliver reliable waterproofing, whether it be internal or external.

We’ve protected everything from bathrooms to rooftops using proven liquid and sheet membrane systems. We value punctuality, clear communication and lasting results. Whether it’s a small repair or a large-scale installation, we take full responsibility for the work.
