Blocked Drains & Drainage

About Our Blocked Drains & Drainage Service

Blocked drains — whether in kitchen waste pipes, bathroom outlets, or main drainage runs — need to be cleared promptly to prevent backups, odours, and potential water damage. PHC Services provides drain clearing and drainage repairs across London, with coverage extending into Essex and Hertfordshire using high-pressure water jetting and rodding to restore flow. In older properties across east and north London, original clay drainage runs have often been in service for a century or more and are susceptible to root intrusion and gradual constriction. In Essex and Hertfordshire, where the geology includes chalk and clay, drainage issues can also relate to ground movement affecting older drain runs. For straightforward kitchen or bathroom blockages, a single high-pressure jetting session typically resolves the problem. For persistent or recurring blockages, we assess whether CCTV drain survey is appropriate to identify whether the drain itself needs repair or relining. All drainage work is fully insured.
