Top tips
Hiring a drain specialist, without the regret.
Four moves that separate a smooth job from a nightmare.
Insist on CCTV before any major work.
Blockages can be hair, roots, collapse or misalignment. A CCTV survey identifies the cause — anyone digging or jetting without one is guessing.
Get the build-over agreement.
Building over a public sewer needs a water company build-over agreement. Find out before excavating — retrofitting one is painful.
No-dig first, dig only if needed.
Most modern drain repairs use trenchless methods (relining, patch-and-cure). If a quote starts with 'we'll need to dig the whole driveway up', get a second opinion.
Check who owns the drain.
Since 2011, water companies own most lateral drains. Blockages outside your property boundary might be the water company's responsibility — and their fix is free.
