There are several situations where a CCTV drain survey is highly recommended. If you experience frequent or persistent drain blockages, an in-depth inspection can reveal whether the problem is caused by recurring build-ups, partial collapses, or tree root ingress. Homebuyers and commercial property purchasers often commission CCTV surveys before finalising contracts, ensuring they are aware of any hidden drainage faults that could result in expensive repairs. If your property has an older drainage system or you’ve noticed issues like slow drains and foul odours despite regular unblocking, a survey can offer clarity on the pipe’s overall health. Construction projects, extensions, or major refurbishments might also require a drain survey to confirm the system is adequate for increased usage. Essentially, if there’s any uncertainty about the condition, capacity, or integrity of your drains, a CCTV survey is an effective way to gain a detailed, visual diagnosis.
