Ensure Waterproofing & Remedial Building
Jake's crew fixed a leaking verandah two previous attempts had failed to solve — and replaced the damaged bedroom ceiling while they were at it.
The clearest signal is that Jake and his crew handle jobs other contractors have already failed at or made worse: two reviewers explicitly mention prior failed attempts before calling Ensure, and both describe a markedly different experience. Across all 7 reviews, the combination of a written scope of works, on-schedule delivery, and post-job site cleanup comes up repeatedly — if those things matter to you on a waterproofing job (and they should), ask Jake upfront whether he provides a written scope and a fixed timeline, since reviewers suggest that's standard practice here.

About Ensure Waterproofing & Remedial Building
Jake leads Ensure Waterproofing & Remedial Building and appears throughout every reviewed project as the primary point of contact — coordinating scopes of work, communicating progress, and overseeing complex multi-trade jobs from start to finish. What sets this outfit apart from a standard waterproofing contractor is their willingness to handle the full remediation chain: when a leaking verandah was found to have damaged two bedrooms below, the team didn't stop at the membrane — they replaced the ceiling and repainted the affected room too. Team member Zac is called out specifically for working hard and conscientiously to hit deadlines, while Bilal and Ali are praised for their work ethic and attention to detail on a large balcony project. Their work has included sheet membrane systems, tile removal and relay, screed installation, and bathroom leak repairs — pointing to a focus on balconies, verandahs, and wet areas on residential properties rather than new commercial builds. One reviewer's experience is particularly telling: they'd previously tried a handyman fix that made the problem worse, then called Ensure, and found both the communication and pricing straightforward by comparison. Homeowners dealing with stubborn or previously botched waterproofing failures — especially where tiles and structural damage are already involved — appear to be the primary fit.
Best for: residential balcony and verandah waterproofing that requires full tile and membrane replacement, rectifying previously failed waterproofing work done by others, and complex jobs where water damage has spread to ceilings or interior rooms.

What types of waterproofing jobs does Ensure Waterproofing handle?+
Based on reviewed projects, their work skews toward balconies, verandahs, and bathrooms on residential properties. They've completed full membrane system installations, tile removal and relay, and screed work — not just surface-level sealant applications. They also take on the downstream damage: one reviewed job included replacing a water-damaged ceiling and repainting an affected bedroom after a leaking verandah was fixed. If your job involves multiple trades or prior failed repairs, that appears to be within their scope.
Who will I be dealing with, and who does the actual work on site?+
Jake is the owner and primary contact — reviewers describe him handling initial consultations, preparing scopes of work, and overseeing jobs through to handover. On-site, team members Zac, Bilal, and Ali are named across multiple reviews, with Zac specifically praised for working hard to meet deadlines and Bilal and Ali noted for attention to detail. Liam is mentioned in one review handling a bathroom leak directly. The picture from reviews is a consistent crew rather than shifting subcontractors.
Do they provide a written quote and scope of works before starting?+
Multiple reviewers mention receiving a detailed written scope of works prior to the job commencing — one reviewer highlights this specifically as a point of difference. Projects are also described as being completed on schedule and on budget, suggesting the quoting process is reasonably thorough. Pricing is described as fair in several reviews, including by a customer who had previously tried a cheaper handyman fix that worsened the problem. It's worth asking Jake to confirm this is standard practice when you make contact.
Are they worth calling if a previous repair attempt has already failed?+
Two of the seven reviewers explicitly describe calling Ensure after a previous attempt by someone else had either failed or made things worse — one had been battling a leaky verandah since 2018 with an earlier unsuccessful fix, the other tried a local handyman who worsened the problem. Both describe a positive outcome with Ensure. This suggests they're comfortable diagnosing and rectifying botched prior work, which requires a different level of knowledge than doing a clean install from scratch.
What areas does Ensure Waterproofing service?+
The business is based in Tuggerah on the Central Coast of NSW. Reviews don't mention specific travel distances or suburb coverage beyond that. Given they're a small crew handling substantial residential projects, it's worth confirming directly whether they cover your area — particularly if you're outside the Central Coast region.
