JI Waterproofing Group
Jake handles both waterproofing and tiling in the same booking — eliminating the handover gap where bathroom leaks typically start.
That said, based on the 8 reviews we analysed, the pattern is unusually tight: every reviewer mentions punctuality, clear communication, or quality of finish, and several name Jake directly for making them feel confident in the waterproofing outcome — which matters more in wet-area work than most trades, given that failures often don't show up for months. For a bathroom renovation where waterproofing and tiling need to happen in sequence, Jake's ability to handle both trades removes a common scheduling and liability headache. Worth asking whether he's taken on more complex or multi-bathroom jobs since 2022, and whether he's still operating at the same volume as a sole trader.

About JI Waterproofing Group
Jake, the sole operator behind this Central Coast waterproofing business, handles both waterproofing and tiling — a combination that matters because most waterproofers sub out the tile work, creating handover gaps where leaks start. Reviews specifically mention bathroom renovations as the core workload, with at least one kitchen splashback tiling job also completed, so he's comfortable across wet-area and non-wet-area tile installs. His approach on-site draws repeated mention: customers flag that he starts work promptly, communicates clearly during the job, and integrates cleanly with other trades — useful if you're running a bathroom reno where a plumber and tiler also need to sequence around the waterproofing. Pricing feedback describes him as fair rather than cheap, with a fast quote turnaround that suits homeowners trying to keep a renovation on schedule. As a sole trader, Jake is the person who quotes, shows up, and does the work — no subcontracting or crew variation to account for.
Best for: combined bathroom waterproofing and tiling on residential renovations, homeowners coordinating multiple trades who need a punctual and communicative contractor, and Central Coast jobs needing a fast quote turnaround.

What areas does JI Waterproofing Group service?+
The business is based in Lake Munmorah on the Central Coast of NSW. Reviews don't mention specific travel radius, so if you're outside the immediate Central Coast area — say, Newcastle or the northern Sydney suburbs — it's worth confirming directly whether Jake travels to your location and whether a travel fee applies.
Does Jake do both waterproofing and tiling, or just waterproofing?+
Based on the reviews, Jake handles both waterproofing and tiling as a combined service, particularly for bathrooms. At least one reviewer also had a kitchen splashback tiled. This is useful for bathroom renovations because it removes the need to coordinate two separate tradies for work that needs to happen in sequence — and puts liability for both stages with the one contractor.
What do customers say about pricing and quotes?+
Multiple reviewers describe Jake as fair on price, and several specifically mention a fast quote turnaround. One review noted he was 'fair with price' after a punctual on-site measure-up. There are no reviews flagging pricing concerns. As a sole trader with low overheads, his pricing may be more competitive than larger waterproofing companies, but it's worth getting a written quote that itemises waterproofing and tiling separately if you need both.
How does Jake perform when working alongside other trades on a renovation?+
One reviewer specifically praised Jake for being 'a good communicator and works well with other trades,' which is a practical consideration for bathroom renovations where plumbers, tilers, and waterproofers need to sequence their work. Reviews consistently mention punctuality, which helps when other tradies are waiting on waterproofing to be completed before they can proceed.
How current is the review history for JI Waterproofing Group?+
All 9 Google reviews appear to have been left in a seven-month window in 2022, with no more recent reviews visible on the platform. This doesn't necessarily mean the business is inactive, but it does mean there's limited public feedback from the past couple of years. It's reasonable to ask Jake directly for recent references or examples of completed work if you want to verify current activity.
