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.

Detect water leak affecting wall

£125

Unity Place, Greater London

16th Sep 2026

Looking for a qualified plumber or leak detection specialist to investigate and diagnose a concealed issue behind an internal wall at a property on Blackhorse Road, Walthamstow (E17). The property is being prepared for sale, so we need a definitive, thorough diagnostic to find the root cause, rather than a cosmetic fix. The Issue: Dark, oily/grease-like stains appearing in separate areas on an inside wall (including around an electrical socket). Distribution strongly suggests 2 issues. A roofing company has already ruled out roof flashing defects or external water ingress from above but no one has gone to the roof. Suspected cause: A slow-leaking water pipe or waste line inside the wall cavity. We are specifically looking for a professional who has and can utilize trace-and-access / leak detection equipment during the initial inspection. Please let us know if you use tools such as: - Moisture meters / testing - Thermal imaging cameras - Acoustic detection or tracer gas (if applicable)

Replace toilet fill valve — small leak (fittings already tightened)

£75

Cann Hall, Greater London, E11

9th Sep 2026

There's a small leak coming from the toilet fill valve connection, where the flexible supply hose meets the base of the cistern (see photos). I've already tried tightening the fittings at both ends of the hose and that hasn't stopped the leak, so it's likely the fill valve itself needs replacing, or there's a worn washer/hose that needs swapping out. What I need: Confirm the exact source of the leak Replace the fill valve and/or supply hose as needed Test to confirm no more leaking after repair The toilet is a bit older, so there's a chance the tank may need to come off for full access — happy to discuss on site if so. Photos attached showing the leak area.

Chris helped replace a leaking toilet valve - would definitely recommend!
