What is a CCTV Drain Survey and Do I Need One?

A CCTV drain survey is a non-invasive inspection using a camera to pinpoint blockages and damage within your pipes, preventing unnecessary excavation.
When facing drainage problems, the traditional approach often involved guesswork followed by disruptive excavation to find the root cause. Today, our trenchless methodology begins with precise diagnosis. A CCTV (Closed-Circuit Television) drain survey is the cornerstone of this approach. It involves our engineers feeding a high-resolution, waterproof camera on a flexible rod into your drains and pipes. This transmits a live feed to a monitor, allowing us to inspect the internal condition in real-time without any digging.
The Trenchless Inspection Process
Our process is designed for minimal disruption. We typically gain access via an existing manhole or drain opening. The camera travels through the system, recording its journey. We assess everything from blockages and root ingress to cracks, fractures, and pipe misalignments. The key advantage is certainty; we see the exact location, nature, and scale of any issue, which allows us to recommend the most targeted and efficient solution—often a no-dig repair like CIPP relining.
When Do You Need a CCTV Drain Survey?
You should consider a CCTV survey in several key scenarios. If you are experiencing persistent blockages or slow drainage that standard clearing cannot resolve, a survey will identify the underlying cause. Before purchasing a property, it is a prudent step to check the health of hidden drainage systems. It is also essential if you are planning extensions or new builds, to ensure your plans align with existing pipework. Furthermore, if you suspect tree root intrusion or want to verify the condition of older pipes, a survey provides definitive evidence, preventing unnecessary excavation based on assumptions.
The survey acts as a preventative measure as well. Regular inspections can identify minor issues before they escalate into major failures, saving significant cost and disruption down the line. For us, it is the first and most responsible step in any drainage repair strategy. It ensures that any subsequent work, especially our no-dig repairs, is justified, accurately planned, and completely effective. We avoid excavating your garden, driveway, or flooring unless it is absolutely necessary, and the survey provides the evidence to make that call.
The Benefits of a Precise Diagnosis
The primary benefit is the avoidance of unnecessary excavation. By knowing precisely what is wrong and where, we can execute a fix with surgical accuracy. This saves time, reduces restoration costs, and preserves your landscaping. The survey report, including recorded footage and a written summary, provides you with a clear document of your drain's health. This is invaluable for planning, insurance purposes, or proving compliance. Ultimately, a CCTV survey transforms drainage repair from a disruptive guessing game into a precise, controlled, and reassuringly clear process.
Frequently asked questions
Is a CCTV drain survey disruptive?
No, it is a non-invasive process. Our engineers access the drains via existing points like manholes. There is no digging or excavation required for the survey itself, aligning perfectly with our trenchless philosophy of minimal disruption.
Can a survey determine if a no-dig repair is possible?
Absolutely. The CCTV footage is the critical tool for assessing whether conditions are suitable for a no-dig solution like CIPP relining. We check for severe collapses, extensive misalignment, or other factors that might require alternative approaches, ensuring we only recommend trenchless repairs when they are a guaranteed fix.
How long does a survey take?
The duration depends on the length and accessibility of the drainage system. For a standard residential property, the survey is often completed within a few hours. The efficient process means we can quickly diagnose the issue and discuss the best solution with you, all in one visit.
