That musty smell. Those dark patches on the wall. Water pooling after rain. These aren’t just cosmetic issues, they’re warning signs of serious problems that get worse and more expensive every day you wait.
Sydney’s climate, combined with poor drainage or aging waterproofing, creates the perfect conditions for water damage.

Excellent servicePosted on Google Chris WolfeTrustindex verifies that the original source of the review is Google. Ohana plumbing provided storm water drains in front of our 1970s house and shed in Springwood, (which is a wet area, creating lots of problems with rising damp) . The workers were here for a week. They were respectful and hard working and we are very happy with the finished result. One side photo provided, ready for planting .Posted on Google Amiya Ranjan DasTrustindex verifies that the original source of the review is Google. I had a blocked gully that was overflowing and our kitchen sink was draining really slowly, so we called Ohana Plumbing. Sam came out and honestly, the whole experience was excellent from start to finish. He quickly figured out what the issue was, explained everything in a way that was easy to understand, and got straight to work. You can tell he really knows his stuff, but more importantly, he’s genuine and takes pride in doing the job properly. There was no rushing, no guesswork, just honest advice and solid work. What stood out the most was how trustworthy and down-to-earth Sam is. It didn’t feel like just another service call, he actually cared about fixing the problem the right way. Everything is now working perfectly and the whole process was smooth and stress-free. I’ll definitely be going back to them for any plumbing issues in the future. Highly recommend Sam and the team!Posted on Google Gareth CarrTrustindex verifies that the original source of the review is Google. We recently reached out to Ohana Plumbing for help with ongoing water issues around our property, and the experience was exceptional from start to finish. As a Sydney homeowner, flood prevention was a major concern for us, and the team took the time to properly assess what was happening beneath the surface — not just treat the symptoms. They explained everything clearly, from stormwater flow to subsoil drainage and how hydrostatic pressure can impact the foundations of a home. What really stood out was their focus on long-term solutions, not quick fixes. You can tell they genuinely care about protecting your home and giving you the knowledge to make informed decisions. Since the work was completed, we’ve had heavy rain with no issues at all — complete peace of mind. If you’re dealing with drainage problems, water pooling, or looking for expert flood prevention in Sydney, I highly recommend Ohana Plumbing. Professional, transparent, and truly specialists in what they do.Posted on Google sajith kunnathTrustindex verifies that the original source of the review is Google. Very good service, highly recommended.Posted on Google Carolyn McCallumTrustindex verifies that the original source of the review is Google. So happy with the water filter that I've had installed. The water tastes so much better and I know I am proactively protecting my lifelong health. Sam and his team were professional with the installation and the whole process was streamlined and this company was excellent to deal with. I would highly recommend them.Posted on Google Giuliano SamueleTrustindex verifies that the original source of the review is Google. Had a really good experience with Sam, he was really clued in on what was happening with our sewerage problem. He identified the site of the problem quickly and alleviated the issue to get us out of trouble over the long weekend then promptly returned on the Tuesday to dig up the pipe and replace what had collapsed. He also installed extra inspection points to make life easier in the future. His price was reasonable and would definitely recommend him in the futureVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
