DON’T IGNORE THE SIGNS

Don't Keep Fixing the Sign of the Leak.
Find the Source.

Water doesn’t follow a straight line. It can travel through walls, concrete, membranes and building elements before it becomes visible. The stain on your wall or ceiling is not always where the leak began.

Common Signs of Water Ingress

LEAK DIAGNOSTICS

Stop Guessing. Find the Source.

Finding where water appears is easy. Finding where it entered is the hard part. Waterseal carries a range of specialist non-destructive instruments so the source can be located and mapped without cutting open walls or lifting tiles.

Diagnostic Methods Include

What You Receive

SPECIALIST INVESTIGATION EQUIPMENT

Specialist Investigation Equipment

Waterseal locates leaks without guesswork or destructive opening up. Our instruments include HF Sensor Moist 350B microwave moisture scanners for reading moisture at depth through tiles, screeds and concrete, the Moist Scan 100 array scanner for mapping large floors and roof decks, FLIR thermal imaging, Sewerin acoustic leak detection for concealed pipework, drain and pipe camera inspection, and articulating borescopes for cavities and hidden voids. The method is matched to the building and the problem, and findings are reported with evidence so the repair scope is based on what was measured.

I had been dealing with water ingress issues for months, with multiple trades attempting to identify and fix the problem without success. Waterseal took the time to methodically track down the cause rather than applying another temporary patch. I really appreciated their communication, honesty and persistence. A big shout out to Adam, who completed the works professionally and thoroughly. Thank you to Leon, Adam and the whole team for finally sorting an issue that others couldn't.

I can't thank the team at Waterseal enough. They went above and beyond my expectations from beginning to end. The communication, organisation and overall project management were outstanding. The tradespeople worked incredibly hard, were friendly, respectful and professional, and treated my home with genuine care. I wouldn't hesitate to recommend Waterseal to anyone looking for a reliable, honest and professional team.

Excellent experience with Waterseal. Leon was very knowledgeable and was able to problem solve where my issue in a wall was coming from, then talked me through how to fix it. What a guy and what a service. Thanks so much!

Lance assisted me on a job involving significant water damage to a wall in my home. It is a rarity to find such honest and thorough expertise. He explained the issue and what was necessary to have it fixed. He didn't overquote or try to get work done that didn't need to be done. I would highly recommend Waterseal and Lance's expertise.

Leon came out to diagnose a very tricky leak situation in my home. He could not have been more helpful or informative and their advanced technology quickly pinpointed the problem and the surprisingly easy solution. Highly professional and absolutely recommended. Five stars indeed!
