My waterproofing co
Endorsed by a 20-year bathroom renovation company as the waterproofer they trust for critical wet area work.
That last reviewer is worth noting because tradespeople rarely put their name to a referral unless they genuinely mean it; waterproofing failures come back on the builder, not the waterproofer. Across the 4 reviews, the consistent specifics are punctuality, clean worksites, and work that's described as done properly — not just fast. The sample is too small to draw firm conclusions, so it's worth asking Mitch directly about his licence class and whether he covers your specific suburb on the Central Coast.

About My waterproofing co
Mitch leads a crew that works across bathrooms, balconies, and multi-bathroom residential projects — covering the full range of wet area waterproofing rather than a narrow niche. What sets them apart, based on how they're described by a fellow trade professional, is the standard of workmanship on work that's inherently invisible once tiling goes over the top — the kind of thing that only becomes obvious years later if it was done wrong. A bathroom renovation company with 20-plus years in the industry specifically called out this team's communication throughout projects, which matters on coordinated builds where delays cascade. Clients working directly with them — not just through builders — describe the same pattern: efficient execution across multiple wet areas in a single visit, work completed on time, and no mess left behind. The crew's cleanliness and punctuality come through independently across both builder-referred and direct-client reviews, suggesting these aren't just one-off impressions. They appear to suit both homeowners organising their own renovation and builders who need a reliable sub to plug into an existing schedule.
Best for: homeowners waterproofing bathrooms and balconies together, builders needing a dependable waterproofing sub-contractor, and multi-bathroom renovation projects where punctuality and clean work are non-negotiable.

What areas does My Waterproofing Co service?+
They're based in West Gosford, NSW, which positions them centrally on the Central Coast. Reviews mention both direct residential clients and builders using them for projects in the area, suggesting reasonable local coverage. However, the reviews don't specify exact suburbs they travel to, so it's worth confirming with Mitch directly whether they'll come to your specific location, particularly if you're at the edges of the Central Coast or in nearby regions.
Do they handle both bathrooms and outdoor areas like balconies?+
Yes — one reviewer specifically mentioned having both a bathroom and a balcony waterproofed in the same engagement, and they were described as professional and thorough across both. Mitch's crew is also noted for completing jobs across three bathrooms in a single visit, suggesting they're comfortable with multi-area scopes. If you have a combination of wet areas to waterproof, that appears to be within their normal workload.
Are they suitable for builders and trade contractors, or just direct homeowners?+
Both, based on the reviews. At least two reviews come from builder or trade contexts — one from a bathroom renovation company with 20-plus years of experience that sub-contracts them regularly, and another from a homeowner whose builder organised them. Their communication and reliability on coordinated builds is specifically praised by the trade reviewer, who noted they're the kind of sub-contractor you can depend on without chasing. Direct homeowners have also hired them independently with equally positive results.
What do customers say about their workmanship quality?+
The standout comment comes from a trade professional who described waterproofing as something that 'has to be done right the first time' and said this team consistently delivers a high standard. Direct clients echo this, describing the work as done properly and on time. Given waterproofing is hidden beneath tiles and only fails years later, the endorsement from someone with 20-plus years in the industry carries more weight than a standard homeowner review — that person sees the consequences of poor waterproofing regularly.
How tidy are they on-site?+
Cleanliness comes up unprompted in multiple reviews, which usually means it genuinely stood out. One homeowner noted they 'didn't make a mess,' and another specifically mentioned Mitch and the crew were clean and on time across a three-bathroom job. For homeowners who are living in the property during a renovation, or builders running a tight schedule with other trades following behind, this appears to be a reliable aspect of how they work.
