Leaking Pipe Repairs Sydney

A drip under the sink, a damp patch on the wall, or a puddle under the house? We find the leaking pipe, repair it and test it before we go.

No surprise bills: $0 call-out and a fixed price before any work starts.

Our guarantee: 12 months on our workmanship, in writing. What it covers

Not every leak is a burst. Most leaking pipes start small: a weeping joint under the kitchen sink, a flexi hose starting to fray, a pinhole in an old copper pipe in the wall, or a fitting under the house that has been dripping for months. Small leaks still do damage over time, to cabinets, floors, walls and the timber under the house, and they add to the water bill. We find where the water is actually coming from, repair the joint or replace the leaking section or hose, then run the water and check it before we leave. You get a fixed price before we start.

The most common spot. Braided flexi hoses, compression fittings, the waste trap and the stop taps all live in that cupboard, and a slow drip there can swell the cabinet floor before anyone notices.

A leaking pipe in the wall shows up as a damp patch, bubbling paint, swollen skirting or mould low on the wall. Pipes behind showers, basins and toilets are the usual suspects, as are pipes hit by a nail or screw.

On houses with a timber floor, a leak underneath can drip for months unseen. Signs are a damp or musty smell, soft flooring, or wet ground under the house when it hasn't rained.

The water service between the meter and the house can leak underground. A soggy patch of lawn, or grass that stays greener along one line, can point to it.

A bill noticeably higher than usual, with no change in how you use water, often means water is going somewhere it shouldn't.

Turn off every tap and water-using appliance and note the meter reading. Check again after an hour or two. If it has moved, there's a leak somewhere.

Damp walls or ceilings, stains, peeling paint, a musty smell or mould in one spot all point to a leak nearby.

Hearing water running when every tap is off is worth taking seriously.

We recently found and repaired a leaking pipe in Guildford. Most leaks are like that one: steady, not a flood. If water is spraying, pouring through a ceiling or won't stop, treat it as a burst pipe.

Book a repair. Put a bucket or towel under it, and close the nearest isolation valve if there is one.

Turn the water off at the meter and call us. We take emergency call-outs 24/7, and for an emergency callout we aim to be with you within 60 minutes.

Common Questions

We trace the water back from where it shows up to the pipe, joint or hose that is actually leaking. If the leak is hidden in a wall or under a slab, our leak detection service uses acoustic, thermal and moisture testing to find it without opening up more than needed.

Often a flexi hose, a compression fitting on a stop tap, or the waste trap. Put a bucket under it and close the isolation valve if it's the supply side. It's a common, straightforward repair.

Usually not. Most leaks are repaired at the joint, or by replacing the leaking section or hose. If more of the pipework is in poor condition, we'll tell you what we found and give you a fixed price for the options.

Yes. A slow leak over weeks or months can rot cabinets and floor timber, stain walls and ceilings, and encourage mould, and it adds to your water bill the whole time.

Yes. We can provide a plumbing report setting out what we found and what we repaired.

It depends on where the pipe is and what's leaking. We give you a fixed price before we start, with a $0 call-out fee.
