A drainage investigation uses CCTV cameras to find the cause of a problem that keeps coming back. In contrast to a routine survey, we work from your symptoms and trace the fault to its source. This helps with recurring blockages, damp patches, bad smells, or slow drains that won't clear. Our push-rod and crawler cameras give a close view of joints and hard-to-reach sections. The survey maps your drainage, finds the defect, and gives clear evidence of the cause. You get a written report with footage and recommendations, useful for insurance claims or disputes with neighbours.
We start by understanding the problem. This means which fixtures show symptoms, when they happen, and what we've tried before.
We trace the drainage outward from the affected area. This records every pipe section and joint, since that's how we find the fault.
We find the cause — root damage, a collapse, a joint fault, or a design flaw. We still document it fully with footage and images.
You get a full report on the problem and where it is. It ranks fixes by cost and effect.
The cost of a targeted drainage investigation depends on how complex the system is and how long it takes to find the fault. Straightforward cases, where the cause is found quickly, cost less, while trickier faults take more time to track down. Request a fixed-price quote online. We confirm the price before we start, and there's no call-out fee.
A standard survey gives a general check on your whole drainage. However, a drain investigation works differently — we work from your symptoms to trace one exact fault. It may cover the whole system, or just the part with the problem.
Yes. Our cameras can reach pipes under an extension or other add-on. We use existing manholes and access points to get there. If there's no access point nearby, we'll talk through options with you.
Yes. Our reports include dated footage and marked-up images. Home insurers accept our clear write-up of the drain's state. We write every report to a standard fit for claims and legal cases.
