Notice a damp patch on your lawn that won’t go away? Or maybe a weird musty smell near the bathroom? These small signs could be the first indication that something is leaking behind the scenes. Leaks like these are common in Ipswich, especially in older homes or properties built on shifting blacksoil. They can go unnoticed for weeks, slowly damaging your home and wasting water. But the earlier you catch them, the easier they are to fix and stop your water bill from skyrocketing. Here’s what makes Ipswich home more vulnerable and the signs to look out for:
Why Hidden Leaks are a Problem in Ipswich Homes
Ipswich has no shortage of charming older homes, but with age often comes outdated plumbing. Pipes can wear down, joints loosen, and slow leaks may start without obvious warning signs. The region’s active blacksoil is another factor. This type of clay expands and contracts with changes in moisture, which puts stress on underground pipes, especially after heavy rains and dry spells. If this persists, the movement can lead to cracks, leaks, or burst pipes. If you’re looking to prevent those kinds of issues before they start, check out our tips on how to reduce the risk of burst pipes in your home.

Throw in Queensland’s hot, humid climate, it doesn’t take long for damp areas to turn into mould or mildew problems. Whether you’re in a character Queenslander home in Woodend or a newer build in Ripley, hidden leaks can creep in when you least expect it, so it pays to stay alert. Aside from damage to your home, they can also quietly waste thousands of litres of water each month. If these go unnoticed, they’ll often show up as a sharp increase on your water bill.
Signs You Might Have a Water Leak
Damp or Discoloured Walls or Ceilings
Yellow or brown stains on the walls or ceilings are often the first clues that there’s something wrong behind the surface. These patches usually show up near bathrooms, laundries, kitchens, or anywhere plumbing runs out of sight. You might also notice plaster starting to feel soft or the surface beginning to sag. Even if the area looks small, this could be a sign that there’s a bigger leak hidden behind the wall or ceiling.
Persistent Mould or Musty Smells
If your home has a damp, musty smell that never goes away, it could be a sign of hidden moisture. These smells often come from areas like skirting boards, cupboards, or under sinks. These are places where a slow leak might be soaking into timber or plaster out of sight. Even if there’s no visible mould, the scent alone can signal that the water is collecting where it shouldn’t be. Bathrooms and laundries are common trouble spots, and if cleaning doesn’t fix the issue, a leak may be the underlying cause.

Peeling or Bubbling Paint
When paint starts to peel, bubble, or lift from the wall, it’s often a sign that moisture is trapped underneath. This can happen when a hidden pipe leak allows water to seep into the plaster or Gyprock behind the surface. It’s very common around bathrooms, toilets, and laundries. While it may seem like a cosmetic issue at first glance, it usually points to something deeper that needs attention.
Low Water Pressure
If your taps or shower suddenly have less pressure than usual and there’s no known issue with the mains, a hidden leak could be the cause. Water might be escaping through a damaged pipe before it ever reaches your fixtures. This can happen anywhere in the plumbing system, inside the walls, under the floor, or even underground. If the pressure drop affects just one area, it could be a localised problem, but if it’s happening throughout the house, it needs to be checked by a plumber.
Unusual Warm Spots on the Floor
If part of your tile or concrete floor feels warm underfoot when you don’t even have underfloor heating, it could be a sign of a leaking hot water pipe beneath the slab. These leaks can go unnoticed for a long time, slowly spreading moisture through the surrounding area. You might not see any water on the surface, but the floor may feel warmer or slightly damp in one particular spot. If you notice this, it’s a good idea to have it inspected before the leak spreads or causes damage to your flooring.

Cracks in Walls or Flooring
Cracks in walls, tiles, or flooring can sometimes be more than just a cosmetic issue. When water leaks into the structure of your home, especially under a concrete slab or behind walls, it can weaken materials like plaster, concrete, or timber. This can lead to cracking or movement over time. If you notice new cracks forming, particularly near bathrooms, laundries, or kitchens, it’s worth considering whether water might be the cause. Leaks under the surface can slowly compromise the integrity of your home.
Wet Patches or Extra Green Lawn Areas
If one part of your lawn always seems soggy or looks greener than the rest, even when it hasn’t rained, there could be a leak in your water supply line or underground sewer or stormwater drainage system. Broken pipes or damaged irrigation lines can allow water to soak into the soil continuously, causing soggy ground or unusually lush grass. These leaks can waste a significant amount of water and often go unnoticed until other problems start to appear.
The Sound of Running Water When Nothing’s On
If you hear water running, trickling, or hissing when no taps or appliances are turned on or in use, that’s a strong sign of a hidden leak. This sound often comes from inside walls, under floors, or near hot water systems. It’s usually easiest to notice when the house is quiet, like at night or early in the morning. If you can hear water but can’t find the source, have it checked as soon as possible before the leak causes further damage.
What to Do If You Spot These Signs

If something doesn’t look, sound, or smell right, don’t ignore it. Taking a few simple steps can help confirm whether there’s a leak and save you from bigger problems later.
1. Check Your Water Meter
Turn off all taps and appliances that use water, then take a look at your water meter. If the dial is still moving, there’s a good chance water is leaking somewhere in the system.
2. Shut Off Water Supply
If you suspect a leak, turn off the main water supply valve to your home. This can help prevent further water damage while you wait for a plumber. Pay attention to whether the sound of running water stops after you shut it off.
3. Take Note of What You’re Seeing
Document any signs like stains, cracks, or puddles with photos and jot down where and when you noticed them. This can help your plumber identify the problem much faster.
4. Call a Licensed Plumber
If you suspect a leak, it’s best to call in a professional. A licensed plumber has the right tools to find the source of the leak without tearing up your walls or floors. Make sure the plumber you hire is QBCC-licensed since this is required for regulated plumbing work. You can check if your plumber is properly licensed using the online licence search tool.
