Even a small leak can waste thousands of litres of water a year and cause damp, mould, and structural damage if left untreated. The challenge is often finding where the leak is coming from, especially when it is hidden behind walls or under floors.

Voltrade plumbers in Sunderland specialise in leak detection and repair. Our engineers use a combination of experience, thermal imaging, and moisture detection to track down the source of the leak before carrying out a permanent repair.

Common causes of leaks

The most frequent causes of leaks in Sunderland homes include corroded copper pipes (especially in older properties), failed joints on plastic push-fit connections, worn tap washers and cartridges, cracked or perished rubber seals on appliance connections, and damaged radiator valves or bleed points.

When to call a plumber for a leak

Call a plumber if you notice damp patches on walls or ceilings that were not there before, a drop in water pressure that cannot be explained, your water meter ticking over when no taps are running, or any visible dripping from pipes, joints, or appliances.

FAQ

How do I know if I have a hidden leak?

Signs include unexplained damp patches on walls or ceilings, a musty smell, mould growth, higher than expected water bills, and the sound of running water when all taps are off. In Tyne and Wear, Tyneside flats, Victorian terraces, post-war estates can make leaks harder to spot behind solid walls.

Can you detect leaks without digging up floors?

Yes. We use non-invasive techniques including thermal imaging, acoustic listening devices, and moisture meters to pinpoint leaks before opening up any surfaces. This minimises disruption and repair costs.

How serious is a small leak?

Even a minor leak can cause significant damage over time. Persistent moisture rots timber, promotes mould growth, and can compromise the structural integrity of plaster and masonry. In Sunderland properties with Tyneside flats, Victorian terraces, post-war estates, hidden leaks are particularly damaging.

What causes pipes to leak?

The most common causes are corrosion in older copper or iron pipes, frost damage to exposed pipes, failed joints from thermal expansion, physical damage from drilling or nailing, and high water pressure stressing weak points.

Can you repair a leaking pipe without replacing it?

Many leaks can be repaired with a pipe clamp, compression fitting, or soldered joint. If the surrounding pipework is heavily corroded or shows multiple weak points, section replacement is more cost-effective long term.
