Billa Waterproofing
Kurt's waterproofing on a granny flat drew unsolicited praise from both the certifier and the tiler who followed him.
Kurt is named directly in three of those four reviews, and in each case the praise connects to a specific outcome: trades downstream signing off on the waterproofing, a leaking retaining wall resolved quickly, a granny flat wet area completed to certifier standard. For a homeowner booking a waterproofing job where the result affects other tradies behind them — tilers, certifiers, builders — that pattern is more useful than a generic 'great service' review. Before booking, it's worth asking Kurt directly about his experience with your specific application (wet area, retaining wall, basement, etc.) and confirming his timeline against your build schedule.

About Billa Waterproofing
Kurt, the operator behind Billa Waterproofing, is the name that appears in every review — handling everything from consultation through to application himself. Reviewers note he's been called in on granny flat bathroom and laundry combos, leaking retaining walls, and new-build projects where downstream trades like certifiers and tilers need the waterproofing done precisely so their work can proceed without complications. That last point is worth noting for anyone mid-renovation: Kurt's approach has drawn specific praise from those subsequent trades, not just the homeowners commissioning the work. He's also taken on reactive jobs where water ingress was already causing damage, identifying the source and resolving it in a way that reviewers say saved them further cost. As a GST-registered company active for around three years, Billa operates in the Saratoga area of the Central Coast, and the work referenced in reviews sits squarely in the residential space — granny flats, retaining walls, and wet areas rather than large-scale commercial projects.
Best for: residential wet area waterproofing on new builds where certifier approval matters, reactive repairs to leaking retaining walls, and granny flat bathroom and laundry projects requiring trades-ready results.

Who actually does the waterproofing work at Billa?+
Based on the reviews available, Kurt is the person running and performing the jobs — customers mention him by name across multiple reviews covering different project types. This appears to be a hands-on, owner-operated setup rather than a crew-based business. That's worth factoring in if you're booking during a busy period, as availability may hinge on Kurt's schedule directly. Confirm lead times with him when you call.
What types of waterproofing does Billa handle?+
Reviews reference granny flat bathrooms and laundry combos, leaking retaining walls, and new residential builds where certifier sign-off is needed. The business sits firmly in the residential space based on what customers describe. There's no mention of commercial or large-scale industrial work in the available reviews, so if your project falls outside residential scope it's worth discussing with Kurt upfront.
Will the work meet certifier and tiler standards?+
One reviewer specifically noted that both their certifier and tiler commented positively on how Kurt's waterproofing was done — calling it out as making their downstream work easier. That's a meaningful signal for anyone mid-renovation who needs the waterproofing layer to be correct before tiling or inspection. That said, this comes from a single review in a small sample, so ask Kurt directly about his experience with your certifier's requirements in your local area.
Does Billa Waterproofing respond to urgent leak situations?+
One customer mentioned Kurt responding quickly to help fix a leaking retaining wall that was at risk of causing further damage. They described him as knowledgeable and credited him with saving time and money. Whether this represents a general emergency callout offering isn't clear from the available data — contact Billa directly to ask about response times for urgent work before assuming same-day availability.
How much experience does Billa Waterproofing have?+
The business has been active for approximately three years based on platform data, and carries 7 Google reviews across that period. That's a modest public footprint, which may reflect the nature of waterproofing work — jobs that go well tend not to generate reviews, and referrals likely drive much of the workload. It's a reasonable starting point, but homeowners who prefer a longer documented track record may want to ask Kurt for references from past jobs similar to theirs.
