Pre-Purchase Drain Survey across London

A pre-purchase CCTV drain survey gives you key facts before you buy a London home. We put an HD camera into the drains. We then write a report to WRCm standards that lists each defect, how serious it is and what repair it needs.

The report helps in price talks, mortgage valuations and insurance applications. It gives you clear evidence that a seller cannot easily dispute. In Victorian and Edwardian homes, a drain survey matters as much as a structural survey. The costly faults, such as roots, displaced joints and collapse, are invisible from the surface.

The report also gives your conveyancing solicitor what they need to raise enquiries with the seller. Book early in the process, because a defect then has time to be priced into the deal before exchange. Older London homes are more likely to have drain faults, so a survey is worth thinking about before you buy.

Think about timing and cost. A survey is a small spend next to a major drain repair after you move in. Since the seller may not know about hidden faults, the survey protects you. It also gives you facts to use in price talks.
