A drainage investigation uses CCTV camera technology to diagnose the cause of persistent or recurring drainage problems. Unlike a routine drain survey, an investigation is targeted — we focus on the specific symptoms you are experiencing and methodically trace the issue to its source. This service is invaluable when you are dealing with recurring blockages, unexplained damp patches, persistent bad smells, or slow drainage that does not respond to standard unblocking. Our engineers use push-rod and crawler CCTV cameras with pan-and-tilt heads that provide detailed views inside pipes, allowing us to inspect joints, connections, and hard-to-reach sections thoroughly. The investigation maps your drainage layout, identifies defects, and provides clear evidence of what is causing the problem. You receive a written report with footage, annotated images, and specific recommendations for resolution. This evidence is also useful for insurance claims, disputes with neighbours over shared drainage, and planning applications that affect existing drainage routes.
We begin by understanding the problem — which fixtures are affected, when symptoms occur, and what has been tried previously. This guides where we focus the investigation.
We trace the drainage from the affected area outward, recording footage of every pipe section, joint, and connection until we locate the defect causing the issue.
Once the cause is identified — whether root ingress, a collapsed section, a displaced joint, or a design fault — we document it thoroughly with annotated footage and images.
You receive a detailed report explaining the problem, its location, and recommended solutions ranked by cost and effectiveness. We can provide repair quotes immediately.
A targeted drainage investigation in the Manchester area typically costs between £150 and £300 depending on the complexity of the drainage system and the time required to identify the issue. Simple investigations where the cause is quickly located are at the lower end. We provide a fixed price before starting and there is no call-out fee.
A standard survey provides a general condition assessment of your entire drainage system. An investigation is problem-focused — we work from your reported symptoms to trace and identify a specific fault. The investigation may cover the full system or concentrate on the affected section depending on what is needed.
Yes. Our push-rod cameras can access pipes running beneath extensions, conservatories, and other structures through existing manholes and access points. If there are no nearby access points, we can discuss options for creating temporary access.
Yes. Our investigation reports include timestamped footage, annotated images, and professional condition assessments that are accepted by home insurance providers. We produce reports to a standard suitable for claims, disputes, and legal proceedings.
