CCTV Subsidence Surveys London

One of the most common causes of subsidence is defective underground drainage. A subsidence CCTV survey is a non-invasive inspection of your drainage system’s condition to look for signs of drain subsidence. 

This is done by inserting a camera through an access point (like a manhole) for minimal disruption, with no excavation needed, as the specialist camera is designed to fit within the pipe diameter. 

The high-definition, waterproof camera transmits video footage to a monitor, and a drainage engineer uses these real-time visuals to accurately diagnose drainage issues that could be causing ground instability.

Typically examining up to 5 metres of the drainage network surrounding the property, a subsidence CCTV drain survey can reveal:

• Wear and tear (such as hairline cracks or joint separations)
• Blocked drains and collapsed pipes
• Animal and tree root intrusions

By detecting leaks and structural damage in the drainage system, we can help you address drain problems that could otherwise lead to more serious property damage and costly repairs without early detection.

Thanks to our detailed reports, our precise surveys can save you time and money with targeted drain repair recommendations.

So, if you’re concerned about drainage problems in London causing subsidence, be sure to contact us for a survey!

The duration of a CCTV subsidence inspection depends on the size of the drainage system and its complexity. For most residential properties, a standard CCTV survey can be completed within 1–2 hours.

However, for larger properties or commercial properties with more complicated drainage networks, this will take longer.

Our process is designed to be as quick as possible with minimal disruption, while conducting a thorough assessment of your drains. When you contact us to book a subsidence survey, a trained engineer can give you an estimate of how long it should take.

Once the survey itself is complete, you should receive your survey report within 48 hours. If you have a tighter deadline and need the results sooner, please let us know about your preferred timeline when you book your survey.

A subsidence CCTV survey is necessary to help identify subsidence caused by drain problems. The video footage is essential to locate damaged drains that may be contributing to structural damage, which could lead to costly repairs if left unfixed.

Our subsidence CCTV surveys can help you identify issues early before they cause significant ground movement. If left unchecked, poor drainage can lead to soggy soil, standing water, water stains, mould growth, and potential foundation failure.

This is why it’s so important to get a professional subsidence CCTV drain survey if you:

• Are buying a property (avoiding unexpected drainage repair costs and fulfilling mortgage lender requirements)
• Have completed a new construction or are planning to build over drainage (ensuring correct installation)
• Need to provide evidence for an insurance claim related to drainage, subsidence, water damage, or flooding
• Experience recurring blockages, surface flooding, or slow drainage and need to pinpoint the cause to fix it
• Are a landlord or local authority carrying out planned maintenance to prevent emergency repairs
• Need to establish the cause of formally identified subsidence (e.g. broken drains, tree root ingress, or structural defects)

From preventative maintenance as part of asset management to assisting structural engineers and loss adjusters in identifying the cause of subsidence, we are here to help and are just a phone call or email away.

The cost of a CCTV survey for drain subsidence depends on factors such as the size of the property’s drain system and the level of detail required. A standard residential survey costs between £250 and £650, while a large commercial site or a survey that requires detailed drain tracing will cost more than this.

When you get in touch with us for a quote, we will provide an accurate cost estimate for what you need. Our surveying services include a non-invasive inspection and survey report, so your drain report will be included in the survey price.

This report will explain what we have found during the survey, what this means for your drainage network and property, and what your next steps should be to address the drainage issues appropriately.

We will always explain your repair options clearly, with full transparency about final costs, so you can make an informed decision before choosing us for your drain repairs in London.
