Upfront Drain Tracing
Drain Tracing & Tracer Dye Testing London
When a drainage problem is hidden from view, you need a clear, honest diagnostic service. Our drain tracing and tracer dye testing in London provides exactly that, backed by a transparent pricing model we publish upfront.

We investigate blocked, slow-draining, or misconnected pipes using CCTV and fluorescent dyes to pinpoint the exact cause and location of the fault, whether under your property, garden, or street.
Our approach is straightforward: we tell you the cost before we start, based on the service required and the time band for the work. No bait-and-switch, no unexpected extras on the final bill.
Our pricing is based on a simple matrix of the service type (e.g., standard tracing vs. dye test) and the time band for the appointment. The fixed rate is confirmed before any work begins, with no hidden call-out or diagnostic fees.

Questions
Drain Tracing FAQs for London homeowners
Why is your drain tracing pricing upfront?
We believe in trust through transparency. Hidden fees and quote gatekeeping are frustrating. Our published service matrix lets you know the cost based on the work needed, before we arrive.
What does tracer dye testing actually do?
We introduce a safe, fluorescent dye into the drainage system. Tracing where it appears—or doesn't—helps us map pipe routes, find leaks, and identify misconnections to surface water drains, which is a common issue in older London properties.
Can you trace drains under my garden or driveway?
Yes. Our CCTV equipment can travel significant distances along pipes. Tracer dye testing is particularly useful for locating buried pipe runs, lost inspection chambers, and assessing where drainage from extensions or outbuildings flows.
What will the report tell me?
The report, supported by video evidence, will identify the fault type, its precise location (with measurements), and the recommended solution. This is essential for planning repairs or proving misconnections to local water authorities.
Do you serve all London neighbourhoods?
Yes, our drain tracing services cover London. The fixed-price model applies whether you're in a Victorian terrace in Islington, a suburban home in Bromley, or a commercial premises in the City.
