Protect Your Property

Living in Killarney Vale means enjoying the benefits of a coastal lifestyle—but it also means facing the challenges of moisture, humidity, and salt air. At Coastwide Waterproofing, we provide expert internal and external waterproofing services designed specifically for properties in Killarney Vale.


Our external waterproofing protects your building’s outer structures—like retaining walls, balconies, and basements—from water penetration. This is especially important in areas close to Tuggerah Lake, where high water tables and heavy rains can compromise foundations.


Inside, we deliver internal waterproofing solutions for bathrooms, laundries, and other wet areas. We use industry-leading membranes and application methods to prevent leaks and moisture build-up that can lead to structural damage or health issues.


With a deep understanding of Killarney Vale’s environment, Coastwide Waterproofing ensures every job is completed with precision, compliance, and long-term durability. We’re here to help your property stay dry, secure, and protected.


Talk to our qualified waterproofers on 02 4306 3524 to book. Our rates are highly competitive.
