Tracing & Fixing Water Leaks London

What happens if a leak goes undetected? Well, the effects can be devastating and involve costly water damage, especially if the leak is extreme and has been undetected for a period of time. A serious flood can be disastrous to the structure of the property affecting its foundations upon which the property stands.

Not to mention the long-term effect that mould can have on a family’s health when left for long periods!
Knowing you’ve got a water leak: This can be tricky, especially when there are no obvious/visible signs. A leak can go undetected for weeks, months even years before the signs begin to show.

What's included in this service?

Water leaks can present themselves in a number of different ways, supply pipes, central heating systems, drainage and waste pipes or any appliances that uses water. Tracing the source of a leak and fixing it, is one of the most common plumbing problems Serviceteam Ltd are requested to undertake.

For water leak repairs we charge ‘by time on site’ and as soon as we are able to pinpoint the cause and source of the leak our engineer will give you an indication of how long the repair will take.

Water leak repairs

If the leak cannot be contained and/or is causing damage to the property or putting people health at risk i.e. when it is seeping into electrical fittings/fuse boxes etc, it is classified as an emergency and should be reported as soon as possible.

In such circumstances you should turn the water off immediately via the stopcock. If the leak is coming from a property either above or adjacent to yours, please contact your neighbours immediately.

How to turn off your water supply

1) Locate and use your internal mains water stop cock. The stop cock valve is often located where the water first enters your property. If you still have the plans of your house it will be marked ‘SC’ on them.

2) The valve is usually found under the kitchen sink.

3) Alternatively locate and use your external mains water stop cock. Please view our video on this page for help with this.

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 plumbers to locate and repair the leak.

What's not included in this service?

  • Any congestion zone, ULEZ or parking charges - This will be added at cost to the final bill (unless a parking permit for the duration of the visit is provided).

    Q: What is the cause water leakage in walls?

    A: Here are some of the most common reasons:

  • Inadequate sealing of pipes.
  • Old sealants around sinks, bathtubs, windows, etc.
  • External wall cracks.
  • Poor quality external pointing.
  • Piping system failure.
  • Roof leaks.
  • Guttering cracked/broken.
  • Basement leaks due to underground piping failures.
  • Q: How do I apply a temporary fix?

    A: Water leakage can be both internal and external. Here are some simple tips you can follow to address both:

    Preventing Water Leakage (Internal)

    1. Ensure that 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, baths, etc. and replace any missing or damaged tiles.
    4. Follow all maintenance procedures/guidelines to ensure all plumbing services are working 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 the water freezes. The tightness of any ‘push fit’ connection relies on the pressure applied by the installer! We would always (where possible) recommend a soldered joint!

    Preventing Water Leakage (Exterior)

    1. First of all, repair any damaged roofing material. Usually this will require professional help. Serviceteam Ltd 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.

    Q: How do I know if the pipes are leaking?

    A: If there’s leak in your system, there will be a few signs you need to look out for:

    1. High water bills (if metered).
    2. Musty smelling rooms.
    3. Stained walls, ceilings, and floors.
    4. Check you water meter has stopped when you shut off the water, if it continues then a leak is present.
    5. Wet/damp areas will be obvious inside (beneath sink/basins/bath/water cisterns etc) and outside your home, stained walls.

    Q: How much do we charge?

    A: We have a fixed price of £95 + VAT for leak detection and repair. If you live within the Congestion Zone or Ultra Low Emission Zone and parking charges will apply.

    Call Us Now

    If you do detect a leak in your property, don’t delay call Serviceteam Ltd immediately on 020 8059 8111

    Therefore, we need to pay close attention to any signs that indicate a leak is present. You may have noticed a musty damp smell that wasn’t there before. Try and trace it back to the source to begin your investigations.

    If you notice any discolouration to walls, this typically indicates a leak is present and should be investigated immediately. It could be an external leak that has penetrated through to the internal walls?

    Check the external drainpipes, guttering and overflow outlets to see if any wet and slimy deposits exist on the external wall beneath the outlet. Water will tend to accumulate at the lowest point, noticeable by a ‘sagging’ appearance in the guttering.

    If a ceiling shows signs of sagging or discolouration, then a leak is present which must be located before it collapses causing any structural damage.

    Concealed Leaks

    There is a degree of difficulty attached to a concealed leak as it could be retained within a solid, stud, or tiled wall, or beneath concrete. Once detected some of the fabric of the building will need to be removed to access the leak. Yes, access will be intrusive, messy, costly and time consuming but necessary unfortunately in order to fix the leak.

    Whatever type of leak, large or small our professional plumbing and leak detection team will manage the leak and complete the repair. Serviceteam Ltd are available 24/7, 365 day a year to trace and repair a leak at your property. We endeavour to fix the leak during the first visit (wherever possible) with the minimum of inconvenience.

Serviceteam completes so many jobs during a year that we can often provide you with a fixed price for the works without attending Other jobs require am enquiry to be raised, so we can compile a quotation. Any photos provided will help us to assess requirements. If your project is large or complex, we will assign one of our qualified engineers to visit and prepare a detailed quotation. Alternatively, you can select serviceteam’s Pay by Time option, certainly if you have an emergency or a “to do” list made up of one or several minor jobs. When on site our engineer will appraise the works required and give an indication of how long the works are expected to take. If we are unable to complete the works within the first visit due to the need for extra time or materials, then we will provide you with a fixed price quotation for the extended works for consideration and authorization before proceeding.
Enquiries can be logged through our website, email, WhatsApp or by calling 020 3538 7067.

At the point of booking your service we will log your preferred payment details card number etc. Payment will not be taken from your credit/debit card until the works have been completed, usually within 24 hours.

How do refunds work?
You are eligible for a refund if you cancel within 14 days of booking or the job has not been started and is not within the cancellation time frame.

What if I want to cancel the appointment?
We understand that priorities and plans change, and you may need to rearrange/cancel your booking. Should this be the case please let us know as soon as possible so we can make the necessary alterations to our work schedules. If we don’t receive enough notice of your cancellation or appointment rescheduling within the terms outlined below, then there is a possibility you will be charged a cancellation fee.

Do I need to provide parking?
As you know parking in and around London can be problematic and extremely costly (depending on the area) if a parking space can be reserved for our engineer it would be appreciated and help increase efficiency of the service provided (no feeding meters etc or mobile app updating). The quote we have provided does not include the cost of parking and/or congestion charge which will be added to the final invoice (if applicable). Please inform your personal account manager if any special parking instructions like parking permit/free parking can be provided. For properties on the rim of the congestion zone and it is not possible for our engineer to attend without entering/clipping the charge zone, we may need to add the charge to the final bill ? Please check with your personal account manager in advance of your appointment if you’re not sure?
