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.

Diagnose & fix intermittent bath leak + fill/level damp wall

£150

Chadwell Heath, Greater London

21st Feb 2026

I have an intermittent water leak coming from under/around my bathtub. It only happens occasionally, but it has caused dripping into the flat below. The outer wall of the toilet/bathroom area is also getting moist. What I need: Diagnose the source of the leak (bath waste/overflow/trap, tap/supply connections, or failed sealant). Repair/replace any faulty parts and reseal where needed. Water-test after repair to confirm the leak has stopped. Wall repair: I removed the paint completely from the damp area. Please apply filler to level/smooth the wall. (I will paint it white later.) Access note: The bath is fitted tight to the wall with filler/finishing. It’s possible the bath panel/bath may need to be loosened or partially removed to access pipework—please confirm if you can do this.

Finished the task neatly and nicely. Explained the issue.

Mixer Tap Leaking in Kitchen (Cartridge Replacement)

£115

Shacklewell, Greater London

3rd Feb 2026

Issue: Kitchen mixer tap leaking from the gap between the hot/cold handle. The water dribbles down the shaft when in use. No flooding, the tap is still usable for now, but needs dealing with. Thoughts:likely a cartridge replacement or issue with sealing. I'd rather not replace the whole tap, but you'll do a diagnosis first and we'll discuss. Hopefully, it's a short one-and-done job: There's a Screwfix and a Toolstation nearby. If after diagnosis, the right part is available, I can nip off and buy it. Or, I can purchase one from you if you carry spares... Budget is for labour if this is the kind of job we're looking at... I'll cover you for parking vouchers during your visit as needed.

Ali came, and knew exactly what to do. Thanks!

Fix pipe leakage under sink

Brownswood Park, Greater London, N4

16th Dec 2025

I dismantled the pipes under my sink after fitting everything back together there is a leak. Specifically the leak is between the top of the ubend and the exit pipe. The problem is that the end of the ubend has a screw nut and the exit pipe is just a flat pipe so the connection isn’t tight enough
