Trace and fix water leaks in London

If you’re experiencing an emergency water leak in London, you must act quickly to prevent further damage to your property. Unattended leaks can cause significant structural damage resulting in costly repairs.

Emergency water leak repairs in London.

The first step in dealing with a water leak is to trace its origin. This may be obvious if water gushes from a burst pipe, but if it’s a gradual and hidden leak, it can cause dampness leading to structural damage. First, look for any visible signs of water damage, such as damp patches on walls or ceilings, pooling on floors, or a decrease in water pressure. If the leak is concealed, then it’s advisable to seek help from a professional.

Once the leak has been located at the source, isolate the water supply to the property to prevent further damage. The stopcock is usually located under the kitchen sink, under the stairs, near the front door, next to the gas meter, in the cellar or outside the property. If you’re unsure where your stopcock is, try and locate it so you are able to act quickly in an emergency.

When you have located the stopcock, find a trusted plumbing service company on TrustPilot or Checkatrade, and keep their number in a convenient place for quick access.

An undetected leak can be a homeowner’s nightmare. Even a minor leak, over time, can cause gradual damage. Long-term leaks can lead to the build-up of mould, producing harmful spores that can pose a serious threat to health.

Mould exposure affects the respiratory system and can lead to severe allergic reactions. If mould is present in a property, it’s a sign that water is the cause, either leaking in from the outside or from a pipe within. Identifying the early signs of mould and treating it immediately is essential.

Water leaks can occur in various plumbing systems, including supply pipes, central heating systems, and drainage pipes. Identifying the source of the leakage can be a complex and time-consuming task, but necessary.

Serviceteam understands the importance of timely services, repairs and prompt response times. To locate a concealed leak, we charge by the hour for time on site. Once located, we will concentrate on fixing it. Should the repair require intrusive access, more time and materials, we will provide a fixed price quotation for your approval before we commence the work.

Act quickly

Immediate action is necessary in an emergency to safeguard your property and its contents. Hopefully, you have done your research and know where the stopcock is situated. With any water leak, time is of the essence to avoid further damage. Once the water has been isolated, the panic, to some extent, is over unless the leak is coming from a neighbour’s property. If so, inform them immediately and isolate the water supply. Then call serviceteam plumbers.

Knowing where to turn off your water supply is crucial for a homeowner. In case of an emergency or for simple maintenance procedures, it is important to be able to isolate the water supply within minutes.

  • One way to do this is to locate and use the internal mains water stop cock, which is typically located where the water first enters your home.
  • This valve is usually found under the kitchen sink and is labelled “SC” on the house plans.
  • If you cannot find this valve, locate the external mains water stop cock. This is situated at the edge of your property.
  • Always be prepared for any situation. Knowing where to turn off your water supply when there’s a leak is invaluable.

Do not forget to contact a professional service provider in London who can fix the issue.
Next Steps:

  1. Depending on the source of the leak, isolating the mains water supply to the property may or may not stem the leak immediately.
  2. Try your best to contain the leak using buckets and towels
  3. Contact serviceteam to arrange for one of our plumbing engineers to visit to repair the leak.
  1. Check all hose connections are secure on water supply lines to various water-consuming appliances (washing machine/dishwasher/Incinerators etc.).
  2. Make sure the external WC cistern overflow setting does not reach the overflow outlet; it will also save water if you happen to be on a metered system.
  3. Reseal sinks and baths and replaces missing or damaged tiles.
  4. Follow all maintenance procedures/guidelines to ensure all plumbing services work properly.
  5. Insulate all pipes that are exposed to freezing temperatures. It helps prevent burst pipes. ‘Press fit’ connections can become uncoupled due to expansion as water freezes. The tightness of any ‘push fit’ connection relies on the pressure applied by the installer! We would always recommend soldered joints!
  1. First of all, repair any damaged roofing material. Usually this will require professional help. Serviceteam tradespeople are always available to complete this type of repair.
  2. Make sure your gutters, pipelines, etc are free of any debris. It will allow proper drainage and water flow.
  3. Ensure good insulation and ventilation.

Concealed leaks are the most challenging of leaks as they are usually hiding within the walls or embedded in concrete. The process of locating where the leak is coming from can be intrusive, messy, and time-consuming. Developing a solution will require removing tiles, floorboards, plaster or brickwork.
