What We Do

Professional Leak Repair Services

A water leak — however small — demands prompt attention. Left untreated, even a minor leak will cause progressive damage to plaster, timber, insulation, and structural elements, while also providing the damp conditions in which mould thrives. Our experienced plumbers respond quickly to repair leaks throughout your property's plumbing system, carrying out lasting repairs that restore full integrity to the affected pipework or fitting.

We repair leaks in all types of domestic and commercial plumbing systems including mains cold water supply pipes, hot water distribution pipes, central heating pipework, radiator valves, boiler connections, under-sink supply hoses, bathroom and kitchen appliance connections, and waste pipes. Whether the leak is a dripping compression joint, a pinhole in copper pipework from electrolytic corrosion, a failed push-fit fitting, or a leaking radiator valve, our team diagnoses and repairs it correctly first time.

For leaks in concealed or hard-to-access locations — inside walls, beneath floors, or behind kitchen units — we work to minimise the access required. In many cases, specialist repair techniques allow the leak to be fixed through a very small access point rather than a full section of wall removal. Where access is unavoidable, we always carry out the work neatly and advise on reinstatement.

Every repair is pressure-tested before we leave to confirm the system is fully watertight. We also check surrounding pipework for signs of corrosion or additional weak points that could fail in the near future, giving you the option to address these proactively and avoid repeat callouts.

FAQ

Frequently Asked Questions

What should I do immediately when I discover a leak?

Turn off the water supply to the affected area if you can — isolating valves under sinks or at the mains stop tap. If the leak is near electrics, switch off the power at the fuse board to that area. Move valuables away from the water, place towels or buckets to contain the spread, and call us. The faster you act, the less damage occurs.

Can you repair a leak behind a tiled wall without removing tiles?

Sometimes, yes. Depending on the location and type of leak, we may be able to repair it through a small access hatch or via a nearby inspection point. Where tile removal is unavoidable, we keep the area as small as possible. We'll always discuss access options with you and give you a clear picture of what's involved before starting work.

How can I tell if a leak is behind a wall or under the floor?

Signs of a concealed leak include damp patches or discolouration on walls or ceilings, peeling paint or wallpaper, a musty smell, warm spots on floors (indicating a heating pipe leak), rising water bills, or the sound of running water when all taps are off. If you suspect a concealed leak, our leak detection service can locate it precisely before any access work is carried out.

Will my home insurance cover leak repairs?

Many home insurance policies include "trace and access" cover, which pays for the cost of finding and accessing the leak (including any associated damage to walls, floors, or tiles). The repair itself may also be covered depending on your policy. We provide detailed written reports and invoices suitable for insurance claims and can liaise with your insurer directly if needed.

Do you repair leaks on central heating systems?

Yes. We repair leaks throughout central heating systems including radiator valves, pipe joints, boiler connections, and pump unions. For heating system leaks, we drain and repressurise the system correctly after the repair and check for any other signs of corrosion or weakness that could cause future problems.
