Homebuyer Drain Surveys in Chislehurst
Buying a property in Chislehurst? A Homebuyer Drain Survey can identify drainage problems that may not be visible during a standard property viewing. Before committing to the purchase, a CCTV inspection can give you a clearer picture of the condition of the property’s underground drainage.
A Drain Survey for Home Buyers is particularly useful for older properties, homes with mature trees or properties where drains run beneath extensions, patios or driveways. Finding a problem before exchange gives you time to discuss the issue with the seller and consider potential repair costs before the property becomes your responsibility.
Common drainage problems found before purchase
Drainage defects are often hidden underground, so they may not be apparent when viewing a property. A CCTV survey can identify issues including:
- Cracked or fractured pipes
- Collapsed or displaced sections
- Tree root ingress
- Blockages and debris build-up
- Open or damaged pipe joints
- Groundwater entering the drainage system
- Gaps that could allow pests to enter
Identifying these problems before buying can help you understand the condition of the drainage system and avoid unexpected repair costs after moving in. These are among the issues BN Drainage’s CCTV engineers commonly identify during surveys.
How does a homebuyer drain survey work?
Our drainage engineer accesses the drainage system through an existing access point and guides a high-resolution waterproof CCTV camera through the pipework. The camera records the inside of the drains in real time, allowing defects to be located without excavation.
The inspection checks the accessible pipework for structural damage, blockages, root ingress and other faults. The survey can also establish the exact location of defects and provide photographic evidence. BN Drainage’s CCTV surveys include a written drainage report and footage, with reports produced to the MSCC5 industry standard.
For a more detailed explanation of the inspection and reporting process, see our CCTV drain survey service.
