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.

Water leak behind a wall

£300

Goodmayes, Greater London

3rd Nov 2026

Hi, Water has been leaking slowly behind a wall for a few months and has caused noticeable damage on both sides of the wall. The source is probably an adjacent bathroom. It's not from the water supply as water meter value is stable when all taps are closed. It's not from radiator loop as boiler pressure is stable. Possibly it's from waste flow, e.g. sink or toilet. I have attached pictures to help you estimate the scale of works required. Please provide a quote for the entire work required, i.e for trace, access, and repair. Thank you.

Bathroom Waste Pipe Leak – Repair Required

£250

South Bromley, Greater London

26th Oct 2026

Bathroom Waste Pipe Leak – Repair Required There is a leak from a bathroom waste pipe caused by a visible split in the pipe. The bath needs to be removed to access and replace the damaged pipe, which may involve removing tiles. The job includes repairing the leak, reinstalling the bath and restoring all tiles and fittings. Photos attached. I’m a school teacher and off work all this week, so I’m flexible with availability. Please only make an offer if you can complete the entire job and follow through with arrangements.

I can see why this man has 5-stars. Unbelievable service and attitude. Happy to do whatever it takes to get the job done. Just when I was about to completely abandon this site he has single handedly changed my views. Really impressed and 5-stars across the board and offered to come over to look at it if there’s any issues in the future. Took 3 trips to get materials and all done in 4 hours. A credit to AIRTASKER

Leak from bath waste pipe

£150

South Bromley, Greater London

24th Oct 2026

There’s a leak from the waste pipe underneath my bath. A professional trace and access investigation has confirmed that the bath needs to be removed to access and replace the damaged pipe. Some tiles have already been carefully removed without damage, but more will need removing. I need someone experienced who can remove the bath, replace the waste pipe, reinstall the bath and put all the tiles back neatly to a high standard. Pictures attached, although the leak is difficult to photograph as it’s deep behind the bath. I have spare matching tiles if needed. Please only respond if you’re experienced in plumbing, bath installation and tiling. I’m based in Bromley-by-Bow, E3, and available all next week.

Fix leaky tap & flickering light

Chadwell Heath, Greater London

I have a leaky tap & a flickering light that needs fixing. And as a bonus sealant around the kitchen sink (if poss).

After much chasing with little communication Keiron finally attended to carry out the works. While he certainly tried, I feel Keiron is perhaps best suited for straightforward jobs and anything more complex might be too much of an ask.

Fix flush button and and leak under the sink

£100

Plaistow, Greater London, E13

14th Oct 2026

Flush button needs to be replaced. I have done in the past. The old code was Grohe dual flush push button assembly - chrome 42268 000. I think the new code is 42204PI0. Tenants have also reported the kitchen sink leaking but it should be minimum effort as it only requires tighting. the the metal trim between the carpet and the tiled floor has lifted and is partially detached. Size is 1.46 cm. Probably needs to be replaced. Also the two bulbs of the kitchen extractor/range hood need to be replaced

Leak in the kitchen

£100

Chingford Green, Greater London

21st Jun 2026

Kitchen Leak Investigation and Repair Required I have a kitchen leak that is appearing between the laminate floorboards. The leak often occurs after the dishwasher has been running, particularly towards the end of the cycle when it is draining. I am looking for someone with plumbing experience to investigate the source of the leak and carry out any necessary repairs.

Yilnas did an excellent job. He quickly identified the source of the leak and repaired it efficiently. He was professional, polite, courteous, and clearly knew what he was doing. I would happily recommend him and would not hesitate to use his services again.
