Water damage is one of the most expensive problems a Perth homeowner can face, and most of it starts small. A slow drip behind a wall, a blocked gutter or a pipe that finally gives way after years of wear can quietly soak timber, plaster and flooring long before anyone notices. The good news is that most water damage is preventable with a few simple habits and regular checks. Here is how the team at Fremantle Plumbing recommends protecting your home.
Why Water Damage Is So Costly
Water travels. A leak that starts in one spot can spread through wall cavities, under floor coverings and into the slab, and the longer it goes unnoticed the more it costs to fix. Beyond the repair bill, ongoing moisture leads to mould, swollen cabinetry, rotting timber, rising damp and unpleasant smells that are hard to get rid of. Many insurance policies also exclude damage caused by long-term leaks or poor maintenance, so prevention really is the cheapest option.
The Most Common Causes of Water Damage in Perth Homes
- Burst or leaking pipes: ageing copper and galvanised pipes, high water pressure and ground movement in Perth’s sandy soils can all cause pipes to split or joints to fail. See our burst pipe repairs page for what to do in an emergency.
- Leaking taps and fittings: a dripping tap or a weeping flexi hose under the sink can waste thousands of litres a year and slowly damage cabinetry. Our leaking tap repairs fix the problem at the source.
- Blocked drains: when a drain blocks, water has nowhere to go and can back up into showers, laundries and gardens. Tree roots, grease and wipes are the usual culprits. Learn more about our blocked drain clearing.
- Hot water system failures: an old or corroded hot water unit can leak or rupture, flooding the area around it. A tank that is more than 10 years old is worth having checked. Read about our hot water system services.
- Stormwater and gutters: blocked gutters, downpipes and failing soakwells can send winter rain into eaves, walls and foundations. Our team handles stormwater drainage and soakwell servicing.
- Failed seals in wet areas: cracked grout and worn silicone around showers, baths and basins let water seep into the walls and floor below.
Early Warning Signs to Look For
Catching a leak early can be the difference between a quick repair and a major renovation. Keep an eye out for:
- Brown stains, bubbling paint or soft spots on walls and ceilings
- A musty smell or mould appearing in cupboards, corners or behind furniture
- Warped skirting boards, lifting floorboards or loose tiles
- A water bill that is higher than usual with no change in your habits
- The water meter moving when every tap in the house is turned off
- Damp patches in the garden or driveway that never seem to dry out
- Low water pressure or the sound of running water when nothing is on
How to Prevent Water Damage: 8 Practical Steps
1. Know where your water mains are
Every member of the household should know where the mains tap is and how to turn it off. In most Perth homes it sits near the water meter at the front boundary. Turning it off quickly in an emergency can save thousands of dollars.
2. Do a simple leak test every few months
Turn off all taps and appliances, note the reading on your water meter, and check it again after an hour without using any water. If the numbers have moved, there is a leak somewhere on the property.
3. Check under sinks and behind appliances
Look for drips, corrosion and swollen timber under the kitchen, bathroom and laundry sinks. Flexible braided hoses have a limited lifespan and should be replaced if they show rust, kinks or fraying.
4. Keep gutters, downpipes and drains clear
Clean gutters before winter and after storms, and make sure downpipes discharge into working soakwells or stormwater systems rather than against the house.
5. Look after your drains
Avoid pouring fats and oils down the sink, use drain strainers in showers and never flush wipes, even the ones labelled flushable. If drains are slow or gurgling, have them cleared before they block completely.
6. Maintain wet-area seals
Re-grout and re-seal showers, baths and splashbacks as soon as the silicone cracks or discolours. It is a small job that stops water getting behind tiles.
7. Watch your water pressure
Water pressure that is too high puts constant strain on pipes, taps and appliances. A licensed plumber can test your pressure and fit a pressure limiting valve if needed.
8. Book a regular plumbing inspection
A professional inspection picks up worn fittings, hidden leaks and failing pipes before they cause damage. For drains and sewer lines, a CCTV drain camera inspection shows exactly what is happening underground without any digging. This is especially worthwhile in older Fremantle homes with original pipework.
What to Do If You Find a Leak
- Turn off the water at the mains, and switch off the hot water system if it is involved.
- If water is near power points or appliances, switch off the electricity at the switchboard.
- Move furniture, rugs and valuables away from the affected area and soak up standing water.
- Take photos of the damage for your insurance claim.
- Call a licensed plumber to find and repair the source of the leak.
