Ribalkin & Wang Plaster Pty Ltd
Alex personally handles every job and returns immediately if anything needs fixing after completion.
The standout detail from those 3 reviews is the post-job follow-through: one customer specifically noted Alex came back immediately to address a minor issue without any friction, which is the kind of thing that separates tradespeople who care about the outcome from those who disappear after payment. At around two years in business, this is still an early-stage operation with a thin review footprint — ask Alex directly for references from recent jobs similar to yours, and confirm the specific scope of waterproofing work he covers before booking.

About Ribalkin & Wang Plaster Pty Ltd
Alex — the name across all three reviews — is the hands-on operator at this partnership-run business, and what stands out is how personally he manages each job from quote through to completion. Operating under a plaster and waterproofing banner, the work likely spans wet-area membrane systems, render waterproofing, and related plastering finishes typical of Central Coast residential builds and renovations. What reviewers actually highlight isn't technical complexity but execution discipline: jobs completed on the promised timeline, and a willingness to return immediately when a minor issue surfaced post-completion rather than leaving it to a callback queue. The quote process itself drew a mention — unusually, a reviewer found Alex genuinely helpful at that early stage, which suggests he invests time explaining scope and options before any commitment is made. At roughly two years in operation, this is a young business that appears to be building its trade through direct referrals and personal accountability rather than scale. Homeowners with a specific wet-area repair, bathroom waterproofing, or plastering job who want to deal directly with the person doing the work are the clearest fit here.
Best for: residential wet-area and bathroom waterproofing jobs where you want direct contact with the tradesperson, homeowners who value prompt follow-up if something needs adjusting post-job, and Central Coast locals still in the quoting and planning phase of a renovation.

Who does the work at Ribalkin & Wang Plaster Pty Ltd?+
All three customer reviews name Alex as the person who carried out and managed their jobs directly. The business is structured as a partnership, but based on available reviews, Alex appears to be the primary operator on site. If you want to confirm who will attend your job, it's worth asking when you call for a quote.
What areas does Ribalkin & Wang Plaster cover?+
The business is based in Ourimbah on the Central Coast of NSW. Reviews don't specify how far they travel, so if you're outside the immediate Ourimbah area — whether in Gosford, Tuggerah, or further afield — confirm their service radius when requesting a quote.
What do customers say about how Alex handles problems after the job is done?+
One reviewer specifically noted that Alex 'came back straight away to fix a small issue' after the job was completed, describing it as going 'above and beyond.' That's a meaningful signal for waterproofing work specifically, where minor post-installation defects can matter. With only 3 reviews available, it's a single data point — but it's a notable one.
Is Ribalkin & Wang Plaster suitable for getting a quote before committing?+
One reviewer commented that Alex was 'very helpful with quotes,' suggesting the quoting process itself is straightforward and informative rather than a hard sell. If you're still in the planning phase or comparing options for a waterproofing job, getting a quote from them appears to be a low-friction experience based on that feedback.
How established is this business?+
Ribalkin & Wang Plaster Pty Ltd has been active for approximately two years and currently has 3 Google reviews — a small footprint for a trades business. That doesn't mean the quality isn't there, but it does mean there's limited independent data to draw on. Asking Alex for references from past jobs similar in scope to yours is a sensible step before committing.
