1. Allspex Tiling
Address: Gold Coast
Contact: +61 401 442 881
Mail: [email protected]
Business hours: Monday to Friday, 9AM – 5PM
Allspex Tiling brings a practical, no-fuss attitude to waterproofing—integrating it smoothly into their tiling work rather than treating it like an afterthought. They don’t oversell, but they do deliver, which is part of what’s earned them steady word-of-mouth praise.
Reviews often highlight how well the team communicates throughout the process and how tidy they keep the space while working, which matters more than most people expect.
Some clients mention a limited range of design options compared to more style-driven firms, but that tradeoff seems to come with greater consistency and fewer surprises.
Their approach leans more functional than flashy, but the finishes still come out crisp and well-aligned. It’s the kind of service that doesn’t try to impress with big claims—it just gets the job done properly, with as little stress as possible.
That quiet dependability is what keeps them in steady demand.
Job completed quickly
“Allspex were so helpful from quote through to completion. The team communicated very well and we knew what to expect while our balcony was being waterproofed and retiled. The job was completed quickly and to a high standard. We would recommend, and will hire, them again for other tiling work.”

2. Shower Sealed
Address: 113 Regatta Parade, Southport
Contact: +61 1300 519 133
Mail: [email protected]
Business hours: Monday to Friday, 8:30AM – 4:30PM
Shower Sealed has carved out a niche for homeowners who want a fast fix without the drama of a full renovation. Their standout promise? No tile removal—just targeted sealing that actually holds.
For many, that alone makes them worth calling.
Reviews consistently mention how little disruption the work causes, with most jobs wrapped up in a single visit. It’s especially appealing for those with recently renovated bathrooms who can’t stomach tearing things up again.
That said, this isn’t a cosmetic refresh; the aesthetic stays the same, which might not suit those hoping to update the look while solving a leak. The team works with quiet efficiency, and they tend to explain their process clearly without overselling it.
It’s a highly specialized service, and that focus shows. If you’re dealing with a persistent leak and don’t want a mess or major expense, they’re a smart, low-hassle option.
Professionals
“I had a leak in my shower and was previously quoted $6,000 by a builder to fix it. Thankfully, I came across a team that uses a modern silicone sealing system, and I asked them to come take a look. To my surprise, they were completely honest and told me that everything was already properly sealed — no work was needed! I was blown away by their honesty, professionalism, and integrity. In a world where it’s hard to find trustworthy tradespeople, they truly stood out. I highly recommend them to anyone looking for reliable and honest service. Absolutely fantastic! Thank you so much”
– Fab Ferreira, Google Review
Experienced

3. ATM Tank Builders and Maintenance
Address: 51 Connor St, Burleigh Heads
Contact: +61 1800 422 444
Mail: [email protected]
Business hours: Monday to Friday, 7AM – 7PM
ATM Tank Builders operates in a league of their own, focusing on large-scale concrete waterproofing projects that go well beyond your average residential fix.
They’re often brought in for industrial or commercial work—think retaining walls, underground structures, tanks, even custom ponds. It’s not glamorous, but it’s meticulous, high-stakes work where failure isn’t an option.
What stands out is their methodical approach and clear communication, especially with builders juggling tight timelines and high specs. Their pricing reflects the scale and complexity of the jobs they take on, so they may not be the best fit for smaller domestic repairs.
Still, for structural waterproofing that needs to last decades, their track record is solid. You’re paying for durability, not aesthetic flourishes. They’re the kind of crew you hire when the job is technical, the site is unforgiving, and there’s no room for shortcuts.
Very professional
“Great service! Very responsive contact center and the follow up has been good. The team came to our house in a couple of hours upon booking and did the pest control job well. Also liked that they have a central online system that communicates with the client on updates and booking by email and phone. VERY professional! I will definitely recommend it and come back again as a customer!”
– Belinda Marcel, Google Review
Experts
“I’d like to thank the crew at ATM Tanks for helping fix my leaking tank so quickly. They managed to repair my tank and install a liner all within a day to avoid any further damage being done. Thanks again.”

4. National Construction and Remedial
Address: Gold Coast
Contact: +61 7 5528 4212
Mail: [email protected]
Business hours: Monday to Saturday, 7AM – 6PM
With more than three decades in the field, National Construction and Remedial has become a go-to for projects where waterproofing is essential.
Their work spans everything from high-rise balconies to basement car parks, often in collaboration with engineers and strata teams. What sets them apart is their ability to diagnose problems that others miss, then back it up with long-term solutions rather than patch jobs.
They’re clearly geared toward larger, multi-unit or commercial projects, so residential clients might find their scope overkill for smaller fixes. Their reports are detailed, their methods tested, and their execution tightly managed.
This makes them particularly useful for remedial work in older buildings with existing structural quirks. They don’t come in with a one-size-fits-all mindset. Instead, they tailor their approach to each site, balancing compliance, cost, and practicality.
A solid bet when the problem is complex and the pressure is on to get it right.
Quick work
“Kirk immediately attended the building and gave me a quote. They could have started the job that week, if it wasn’t for Strata Title company processes. That didn’t bother them and they worked closely with us and the Strata company. In the end it took a couple of weeks. This is messy work, but they had all the right equipment to ensure the mess was non-existent, and the finished product was like new! Have a look at the photos. I would highly recommend NRC, and have no hesitation to use them again. They provide quick and high quality work with exceptional customer service.”
– Mick Van Lathum, Google Review
Always available
“NCR renovated and waterproofed the garden beds in and around our unit block. Work was of a high quality. Carried out in a timely fashion and indeed finished ahead of schedule. Always available to answer questions and offer helpful and cost effective alternatives and solutions. I highly recommend NCR.”

5. BRS Building Rectification Services
Address: 4/10 Enterprise St, Molendinar
Contact: +61 7 5539 3588
Mail: [email protected]
Business hours:
- Monday to Thursday, 8AM – 4PM
- Friday, 8AM – 3PM
BRS takes a measured, investigative approach to waterproofing, which makes sense given their focus on persistent or recurring leaks. They don’t just patch over the problem—they dig into why it’s happening in the first place.
Their team is often called in after multiple failed attempts by others, particularly for stubborn balcony or rooftop issues. Reviews point to their diagnostic process as a key strength, with clients appreciating the level of detail in their reports before any work begins.
On the flip side, this thoroughness can slow things down at the start, so they may not suit urgent, quick-fix jobs. They also handle more niche problem areas like planter boxes, which tend to fall through the cracks with general contractors.
With over three decades in the industry, they’ve built a reputation for solving the leaks that most others give up on. Especially useful when you need more than just surface-level repairs.
Outstanding team
“The two main workers on site were outstanding as were other members of the support team. Resident safety and convenience were always observed. Workers were always approachable and willing to answer questions about aspects of the job. BRS also were able to coordinate with other tradespeople involved in this job flexibly so that delays and problems did not occur. Our confidence in the work of BRS is reflected in our strong interest in having them complete other jobs in our apartment block. We know they will do our jobs professionally and without drama. We also know BRS will complete our jobs at a fair price. Thanks again to Ben and the BRS team for a job well done.”
– Peter Johnson, Google Review
Exceptional work
“During the recent window replacement project at our building, I experienced no safety concerns or disruptions to my access to the interior and exterior of the premises. The BRS team members demonstrated exceptional vigilance and support throughout the project. I extend my sincere gratitude to Ben and his team for their exceptional work. When considering your next project, BRS stands out as the preeminent choice. Their expertise and dedication are unparalleled.”
