Terrigal’s stunning beachfront location is one of its greatest assets—but it also brings unique waterproofing challenges. At Coastwide Waterproofing, we specialise in protecting homes and commercial properties in Terrigal from the constant exposure to coastal moisture, sea spray, and heavy rainfall.

Our external waterproofing services create a strong barrier around your property’s exterior—ideal for safeguarding rooftops, balconies, foundations, and retaining walls. This prevents water from seeping in and causing structural issues, particularly in sloped or elevated coastal blocks.

Within the home, internal waterproofing is just as crucial. We expertly seal bathrooms, laundries, and kitchens to stop water leaks at the source, ensuring a healthier and longer-lasting living space.

Whether you’re building new or renovating in Terrigal, our licensed team delivers compliant, high-quality waterproofing solutions designed to withstand the coastal elements. Coastwide Waterproofing is your trusted partner in keeping your property dry, durable, and ready for the seaside lifestyle.
