When you need it

Why use a professional

What happens if you leave it

Small leaks become big bills.

  • Higher water bills from constant drips.

Useful guide

Plumbing problems worth fixing now

A dripping tap can waste a surprising amount of water over a year. It's usually caused by a worn washer or cartridge and is a quick, inexpensive fix compared with the water it wastes.

A toilet that keeps running, refills on its own or takes a long time to stop filling usually has a worn fill valve or flush valve. Left alone, it wastes water and can wear out further.

Low water pressure can be caused by a partially closed or failing stopcock, a blockage, a leak or the supply itself. We check where in the system the pressure is being lost.

Stains on ceilings, damp patches on walls or a musty smell often point to a slow, hidden leak. Finding and fixing it early prevents rot, mould and costly repairs to plaster and flooring.

Everyone in the home should know where the stopcock is, and it should turn freely. Stopcocks that haven't been used for years often seize. We can replace them so you can turn the water off quickly in an emergency.

When you're renovating a kitchen or bathroom, we can move and extend pipework to suit the new layout. Copper pipework we install carries a 10-year guarantee.

Because we also work on boilers, cylinders and heating systems, we can deal with plumbing that connects to your heating without you needing a second trade.

Outside taps and pipework in unheated spaces such as garages and lofts are at risk of freezing in winter. Insulating exposed pipes and fitting an isolation valve to outside taps, so they can be drained down before a cold spell, helps prevent bursts. We can add lagging and valves while we are on site for other work.

Before we start any plumbing job, we explain what we have found, what needs doing and what it will cost, so you can make an informed decision. Once the work is done, we test the repair under pressure, check for leaks and leave the area tidy.

Copper remains one of the most reliable materials for domestic pipework. Joints are soldered or compression-fitted depending on location and access, and pipework is clipped and supported correctly to stop noise and movement. We use copper for pipework covered by our 10-year guarantee.

Waste pipes and traps under sinks, basins and baths can leak or block over time. We repair and replace them, and check the connections that most commonly cause slow leaks inside kitchen and bathroom cabinets.

Isolation valves on taps, toilets and appliances let you turn off water to one fitting without shutting off the whole house. If yours are missing or seized, we can fit or replace them so future repairs are simpler.

If you have a burst pipe, turn off the water at the stopcock straight away, switch off the electrics in the affected area if water is near them, and call us. We run a 24/7 service across Harrow, North West London and Hertfordshire.
