Some access may be needed depending on where the leak is. We aim to keep disruption to a minimum where possible. If reinstatement, restoration, or repairs after access are required, that may involve additional works depending on the situation.
We use a range of leak detection methods and technology to help locate the source with a non-destructive approach where possible, while staying guided by the evidence on site.

Consider getting help if you've noticed any of the following in your Armagh property:
Or staining on ceilings or walls that keeps recurring despite treatment.
Mould that keeps returning in the same area despite cleaning and ventilation.
A musty smell or a damp feel in a room that persists.
Boiler pressure repeatedly dropping (sealed systems).
Or intermittent air in the lines that can't be explained.
Warped skirting, or bubbling paint that indicates water damage.
If water is near electrics, prioritise health and safety and contact a professional immediately.
Homeowners in Armagh often contact us for issues such as:
Including leaks tracking along grout lines and behind tiles.
Around radiators or heating systems causing pressure drops.
Hidden leaks in underfloor heating systems requiring specialised detection.
Affecting water pipes and incoming supplies, often causing pressure issues.
Where buried pipework is suspected of leaking, requiring specialised equipment.
That may need burst pipe repair and urgent isolation support to prevent damage.
Trace and Access is the industry term for finding a hidden leak and exposing it for repair. It covers the detective work and the access required to get to the source of the problem.
Most UK home insurance policies distinguish between fixing the pipe (which is often a maintenance cost) and the damage caused to get to it. "Trace and Access" focuses on the latter.
If you're making an insurance claim, your insurer will likely need proof of where the leak was and what work was required to reach it.
Clear, fact-based documentation with photos of the leak and the access work.
A detailed record of what we found, helping you substantiate your claim.
Itemised breakdowns where needed to help you evidence the work.
While we cannot confirm your specific policy coverage, we give you the clear facts and professional evidence you need to support your claim.
If you're seeing signs of a hidden leak and want clear, practical next steps, a short call is the simplest place to start. Tell us what you've noticed and where, and we'll explain how we can help.
