Top Leak Detection related questions

Costs vary when booking moisture leak detectors. This may depend on how severe the leak is. Generally, you can expect prices to fall between £550 and £1,200. Using tracer gas to detect leaks can bring your total costs even higher. 

There are basic checks to pull a DIY leak detection, such as monitoring your water meter. However, working with an expert with years of proven experience helps ensure a more accurate detection. 

You can trust that Taskers will always prioritise non-invasive methods, although there may be some cases when digging will be required to access the leak. Inform your Tasker if you’d like to keep disruptions at a minimum so they can come up with possible compromises.

Absolutely! Catching leaks early on prevents you from having to spend a lot on repairing structural damage. It also allows you to keep your property intact for more years to come.

This is on a case-to-case basis. If your Tasker will perform tests like tracer gas leak detection, you may have to turn off the water temporarily. Discuss this with your Tasker to get expert advice on how to prepare ahead of time. 

Small leaks may seem harmless, but they can quickly escalate and cause extensive damage and even mould. If you ignore them, you may end up with more repair work than what’s initially necessary. (If this does happen to you, feel free to book a mould removal expert on Airtasker!)

It’s best to work with professionals when drying your property. You can ask your moisture leak detector if they offer this as an additional service or if they can recommend specialists who use industrial dehumidifiers and issue certificates of dryness.

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.

Fix a leaking bottle trap

Acton Green, Greater London, W4

24th Oct 2025

Need a leaking bottle trap under sink fixed. Reattach or replace. Very short on space

Really happy I found Silva. He’s clearly very talented and skilled. What was thought to be a simple task of replacing a bottle trap, turned into a complicated job because of the structure and placement of my pipe work. Silva went the extra mile to disconnect and re attach the pipe and guided me on what he thought was best & not the easiest for him. Really pleased I’ve found him!! I’ve already booked him in for more work. Highly recommend!!
