Professional leak detection in Derry typically costs between £500 and £1,000 for most residential properties. The final price depends on your property size, the detection methods needed, and how accessible your pipes are. We provide transparent, upfront quotes with no hidden charges, and we can often split costs between detection and access work for insurance claim purposes. Many homeowners find their insurance covers the detection cost under their trace and access policy—we’ll help you check your cover before starting work.

No. We use non-invasive technology including thermal imaging cameras, acoustic sensors, moisture meters, and tracer gas detection to find leaks without lifting floors or breaking through walls. In over 85% of cases, we locate the exact leak position without any destructive work. When access is necessary, we keep it minimal, targeted, and tidy up professionally afterwards. This approach saves you money on repairs and means less disruption to your home.
Most residential leak detection visits in Derry take between 1.5 and 3 hours, depending on your property size and the leak’s location. Straightforward cases are often resolved within 2 hours. We’ll provide you with a written report including photos and recommended repairs on the same day, and many repairs can be quoted on-site so there’s no delay getting your plumbing sorted.
Most UK home insurance policies include £5,000 in “trace and access” cover under the Escape of Water section. This typically covers the costs of finding and accessing the leak but not always the repair itself. We’re approved by major UK insurers and provide detailed written reports with photos within 48 hours to support your claim. Before starting work, we can offer free telephone advice about your specific policy and help you understand what’s covered.
Common signs include unexplained increases in your water bill, damp patches on walls or ceilings, musty smells, warm spots on floors (from central heating leaks), the sound of running water when taps are off, or reduced water pressure. You can check your water meter—turn off all taps and appliances, note the reading, wait an hour without using water, and check again. If it’s changed, you likely have a leak somewhere.
General plumbers often locate leaks by lifting floors, removing sections of wall, or digging trenches—which creates extensive damage and high repair bills. Specialist leak detection companies use advanced equipment like thermal imaging, acoustic sensors, and tracer gas technology to pinpoint the exact leak location first. This means targeted access, minimal disruption, and lower overall costs. We find leaks that general plumbers have missed, often saving homeowners thousands in unnecessary excavation work.
