What do leak detection services include?

To keep your home safe from water damage, it's crucial to work with expert moisture leak detectors for a thorough job. Some leak sources can be difficult to locate, especially when using minimally invasive procedures that enable you to preserve your home's integrity. 

By booking a leak detection service on Airtasker, you can enjoy the following:

Site assessment

Every leak detection process begins by thoroughly assessing your property. Taskers will identify areas most likely to have a leak (a step also called prelocation) by checking for visible signs like damp walls, blistered plaster, or pooling water outside. You can also expect them to perform advanced inspections, such as monitoring the water meter for unseen leaks, provide you with further insights and help them plan the next steps.

Advanced leak detection

The goal of moisture leak detectors is to locate and repair leaks without any unnecessary damage to your property. They do this by using tools like thermal imaging, inspection cameras, ground listening devices, and acoustic sensors to quickly identify possible leak areas and confirm where the leak exactly is. If at all required, tracer gas (usually helium) can be used to track stubborn leaks.

Detailed reporting

Once the leak is detected, your hired moisture leak detector will provide a detailed report. This report includes images and recommendations on how to move forward. They will walk you through your options based on the findings — whether you'll need extensive repairs or minor fixes will suffice. 

If the source of leaks turns out to be significant damage on your roof, fascia, or downpipe, you can work directly with a specialist to make the necessary repairs or replacements to these key parts of your home. Leaks can also be caused by a faulty hot water system. If this proves to be the case, you can book a Tasker specialising in this area.

Post-repair restoration

Following the repair, your Tasker can offer additional support such as water damage remediation and industrial drying. Feel free to inquire about these services in advance to ensure you hire an expert who can accommodate these extra steps for long-term protection.

Urgent kitchen tap and under-sink leak repair

£300

Streatham, Greater London, SW16

20th Oct 2026

Urgent under-sink leak and leaking kitchen tap repair I need a qualified plumber to investigate and repair a leak from my kitchen tap and the plumbing underneath the sink. There appear to be two areas of leakage: - Around the base of the tap: Water is leaking from around the top of the sink tap and running down onto the worktop and floor. - Underneath the sink: There is also a leak below the sink. A flexible hose/pipe and a heavily rusted metal fitting are visibly wet, and the surrounding cupboard wood is starting to swell and warp from the moisture. I'd like someone to identify the source of both leaks and carry out the necessary repairs, including replacing any faulty hoses, seals, connectors or fittings as required. The tap may also need resealing or replacing, depending on the cause. Please bring the necessary plumbing tools and common replacement parts. I'd appreciate an early appointment, as the ongoing leak is causing water damage to the kitchen unit. Please assess the damage and confirm the likely repair and cost before carrying out any additional work.

traditional two-handle mixer with white ceramic lever handles, leaking on the hot side (left). This happened once previously and we used an Allen key to undo the grub screw and take the handle off, put it on in the right spot and take it off again, need to do the same again. Shouldn’t be any parts required. Access to turn off the water is directly under the sink and easily accessed. Should be a small job, open to a plumber or handyman

We have evidence of a possible water leak from the bathroom. After longer showers, water is leaking into the adjacent kitchen, and there is a brown water stain on the bathroom wall. There is also mould in the bathroom, kitchen and bedroom. We need the source of the water ingress investigated urgently, as we’re concerned that moisture may be getting into the building fabric.

Stuart was very knowledgeable and knew what the problem was with our leaky shower straight away. Would definitely use again!

Replace Leaking Kitchen Sink Waste Trap / P-Trap

£75

Bermondsey, Greater London, SE1

17th Aug 2026

I’m looking for a plumber to repair my kitchen sink waste pipe. The existing P-trap/U-bend has come apart and I haven’t been able to refit it correctly. I purchased what I thought was the correct replacement, but it appears the fittings/washers aren’t compatible with my existing pipework. Job required: * Assess the current waste pipe setup. * Supply any correct fittings/washers if needed. * Replace and fit a new P-trap/U-bend. * Ensure all joints are watertight and test for leaks before leaving. The sink is currently unusable as the waste pipe has come apart (see photos). Please let me know: * Your availability. * Whether you’ll bring any standard 40mm waste fittings that may be required. * Your total price including any small parts. Looking to have this fixed as soon as possible.

Great job and called out straight away to us - would highly recommend
