Leak Detection in Co. Dublin
40 businesses offering leak detection across Co. Dublin.
With most leaks the repair is the easy part. Finding the leak is what you are paying for, because water travels along joists, under screed and behind dry lining before it shows itself, so the wet patch on the ceiling is rarely under the failure. The signs worth acting on are a system pressure gauge that keeps falling, a warm strip on a floor where nothing warm should be running, a musty smell in a press, and staining that returns after being painted over.
A leak detection specialist works non-destructively before anything is opened up. Acoustic listening equipment picks up the sound of water escaping under pressure through a floor. Thermal imaging shows temperature differences where warm water is tracking through a structure, which is why underfloor heating and hot feed leaks are often the easiest to locate. Tracer gas is introduced into a drained pipe and detected where it surfaces, useful on cold pipework that makes no noise. Moisture meters map how far the damp has spread. The point of all of it is to lift one slab rather than five.
Not every damp patch is plumbing. Failed flashing, a blocked gutter, a cracked render or condensation all imitate a leak convincingly, and a good specialist will rule those out rather than start cutting. Home insurance policies often cover the cost of finding a leak, usually described as trace and access, separately from the damage itself, so it is worth reading your policy schedule before booking. Cost follows the type of construction, how much of the run has to be surveyed, and whether the repair is included in the same visit.

Common questions
How do I know if I have a hidden leak?
Turn off every tap and appliance and check whether the system still shows movement, then watch the boiler pressure gauge over a few days. Falling pressure on a sealed system, a persistently warm patch of floor, a musty smell, or staining that comes back after redecorating all point the same way. Where a supply is metered, a meter that keeps counting with everything closed off is the clearest evidence there is.
Will they have to lift my floor?
The purpose of a detection survey is to avoid exactly that. Acoustic equipment, thermal imaging and tracer gas are used to narrow the leak down to a small area first, so any opening up is targeted. Some access is usually still needed to make the repair, but the difference between a located leak and a guessed one is the difference between one hole and several.
Is the leak my responsibility or the water utility's?
Inside the property boundary, the pipework is generally the homeowner's responsibility. A leak on the public side of the boundary is normally Uisce Éireann's. If you cannot tell which side it is on, that is itself a reason to have it traced before you commit to any repair work.
Could the damp be something other than a leak?
Frequently. Blocked or leaking gutters, failed flashing around a chimney, cracked render and straightforward condensation all produce damp that looks like a plumbing leak. The tell is usually timing: damp that worsens during and after heavy rain is more likely to be coming in from outside, while damp that is constant regardless of weather is more likely to be a pipe.
