We often get called out to a water damage restoration job as the first point of inspection, and quite quickly we can tell what has caused the water damage. With over 15 years of attending and restoring water damage jobs, we see some weird and wonderful causes. More then likely the cause will be one of the items listed below. Some of which with regular inspection or maintenance could reduce the chances of the event happening. Read our list of the top 5 most common causes of water damage in homes.

Top 5 Causes of Water Damage in your home

  1. Flexi Hoses Leaking / Burstingunder sink flexi hose burst pipe flooded kitchen.jpg

In our experience, the number one cause of water damage would have to be Flexi Hoses bursting or leaking. Flexi Hoses are the hoses that are found under your kitchen sink, bathroom sink, and even toilet, and connect the mains water inlet to each tap. Commonly they have stainless steel braided sheath. When damaged or weakened due to rust or a breakdown of the material. These hoses can leak / or burst,  flooding  your home and causing extensive water damage. It pays to check your flexi hoses at regular intervals and replace every 5 years to make sure you don’t get a nasty surprise.


  1. Dishwasher and Washing Machine Internal Pipes

We quite often get called to Water Damage Restoration jobs where a house is flooded due to the hoses on either the dishwasher or the washing machine bursting. As these pipes are quite commonly out of site and out of mind it is hard to prevent. Just make sure if your washing machine and dishwasher are over 5 years old, give them a quick inspection and make sure the rubber hose isn’t perishing. If it is, give you appliance technician a call to replace them. It could save you big time down the track.


  1. Leaking Plumdingerwater damage cairns leaking pipe plumbdinger

It sure sounds like a funny name for a professional item, a bit like the thingy-ma‐jig. However a Plumdinger is a small item that connects the bathtub drain to the plumbing pipe below. Chem Safe have attended a lot of water damage jobs where the Plumdinger was the cause. Over time, through movement and use, it can work its way loose and then all of a sudden start leaking water under the bathtub unbeknownst to the home owner, causing extensive water damage over time.

There is a phillips head screw that requires to be nipped up tighter every 6 months or so. This should minimize your chances of an issue occurring.


  1. Cyclone , Storm, Heavy Rain Water Damage

Most people think this is our main source of work, but the truth is, burst pipes happen far more often then nasty weather events, thankfully. We all love living in QLD and as a part of that, we frequently have to experience quite serious weather events. Storms and flooding can cause internal water damage in homes, by water or rain entering through window frames, under doors, flying debris causing smashed windows, tree branches damaging the roof causing it to leak. These are just some of the ways a weather event can cause water damage in your home.

There is no real way to protect from this type of water damage except following standard storm preparation processes as outlined by local authorities. Chem Safe Water Damage Services are there to help and mitigate the damage. We have performed water damage restoration work to storm affected areas in Brisbane, Rockhampton, Mackay, Townsville, Mount Isa, Cairns, Cooktown and Weipa over the last 15 years.


  1. Air conditioner drain pipes

Queenslanders all need and love their air conditioners, but in winter we turn them off until the heat of summer kicks in. Did you know that air conditioners have a drain pipe that when in use constantly moves water to the outside of your house. With the lack of use over the cooler months and full on use in summer, we have seen these pipes blocked with all sorts of things, from geckos and wasp nests to render and paint covering them on newly built or renovated houses.

A yearly service will fix this and also keep the air conditioner running at its best. A blocked air conditioner pipe can cause internal damage to your walls and floors if left unchecked.


In addition to these causes, we have also seen things like water filters, hot water systems, plastic piping in the ceiling, sink overflows, burst mains pipes, leaking toilets, blocked gutters and even a burst fish tank cause all ranges of water damage in peoples homes. Water damage is always an unwanted, unexpected nasty surprise. If it ever happens to you, then be sure to call us as soon as you notice, so we can get there quick, and help you minimise the damage caused.
