    Our Leak Detection Services

    Our engineers use cutting-edge equipment and proven techniques to pinpoint even the most difficult leaks. Using acoustic listening devices, thermal imaging, moisture mapping, and tracer gas technology, we find the exact location of a leak without any guesswork.

    Our services include:

    • Central heating and boiler leak detection

    • Underground and mains water leak detection

    • Bathroom, kitchen, and internal plumbing leaks

    • Flat roof and ceiling moisture detection

    • Pipe tracing and system pressure testing

    • Insurance-approved trace & access reports

    • Water pipe replacement and repairs

    We also provide ongoing monitoring and moisture control to help prevent future water damage or mould growth. Whether you’re dealing with a residential issue, a commercial water system, or a large property network, our Basingstoke team can tailor the approach to your exact requirements. Every leak detection visit is carried out with precision, care, and minimal disruption to your property.

    Commom Problems

    We regularly help customers throughout Basingstoke, Chineham, Hatch Warren, Kempshott, and Old Basing with issues such as:

    • Damp patches appearing on floors, ceilings, or walls

    • Low boiler pressure and constant refilling

    • Water meter running when no taps are on

    • Mould, mildew, or musty odours indoors

    • Warm spots on flooring (suggesting underfloor heating leaks)

    • Water pooling outside or soft ground around pipe runs

    • Unexplained spikes in water bills

    • Peeling paint or lifting flooring caused by hidden moisture

    Basingstoke’s mix of modern and older housing means water leaks can appear in many forms — from corroded copper pipes in 1970s homes to fractured plastic fittings in newer developments. Our engineers understand these local building types and know exactly where to look first. If you’ve noticed any of the above signs, it’s best to book a survey early before the leak causes long-term structural damage.

    What to Expect

    When you book with Leak Detection South, you can expect a clear, structured, and professional approach designed to minimise stress and disruption.

    Assessment & Consultation – Our visit begins with a detailed discussion about your issue — water pressure drops, rising bills, or damp areas — followed by a visual inspection of likely problem points. We’ll assess the plumbing layout and isolate possible zones before testing begins.

    Leak Detection & Diagnostic Testing – Using a combination of acoustic listening, thermal imaging, tracer gas, and pressure testing, we systematically locate the leak’s source. Each method is non-destructive and allows us to trace leaks through concrete, beneath floors, or behind walls without unnecessary damage.

    Findings & Evidence Report – Once identified, we’ll document the results in a detailed written report including images, moisture readings, and professional repair recommendations. This document is ideal for insurance trace-and-access claims or record keeping.

    Repairs & Aftercare – Where possible, we can carry out immediate repairs or arrange them through our trusted partners. We’ll also provide advice on preventing future leaks, improving system performance, and protecting your property long-term.

    Client Reviews

    Prompt, polite, and professional. From my first call to completion, the service was excellent. They arrived on time, explained the process clearly, and found a leak that two other plumbers couldn’t locate. Really tidy and respectful of our home.

    Natalie H.Kempshott, Basingstoke

    Impressed with the technology used. The engineers used tracer gas and acoustic equipment to find a small leak under our driveway. No digging, no mess, and the report made our insurance claim easy. Fantastic service from start to finish.

    Alan BaileyChineham, Basingstoke

    Saved us hundreds on repairs. We were quoted thousands to dig up the garden to find a leak. Leak Detection South located it precisely using their equipment, and it was fixed the same day. Couldn’t ask for better.
