Experienced blocked drains specialists in listed buildings
Greater London Drainage has been serving listed buildings and the surrounding boroughs for over two decades. Our team of certified drainage engineers handles every type of blocked drains issue, from simple blockages. All vans are fully equipped to diagnose and resolve most issues on the first visit, with no callout fee and clear, fixed pricing before any work begins.
listed buildings properties often have specific drainage characteristics. Older buildings commonly rely on combined sewers and vitrified clay pipes that benefit from CCTV inspection. Newer developments typically have separate foul and surface water systems with PVC-U pipework. Our engineers understand both, and we hold appropriate insurance, including £5 million public liability cover.
Common blocked drains issues we resolve
- Recurring blockages caused by fat, scale, root ingress or pipe defects
- Slow drainage from sinks, baths, showers and toilets
- Unpleasant odours indicating water seal loss or sewer venting issues
- Internal or external overflow requiring immediate response
- Damage from tree roots, particularly in listed buildings where mature sycamore and lime trees are common
- Collapsed or fractured drains identified during CCTV surveys
- Subsidence-related drainage failure in older listed buildings properties
Our approach to blocked drains in listed buildings
Every blocked drains job starts with a thorough assessment. We don't simply attack the symptom. For recurring issues, we recommend a CCTV drain survey to identify the root cause, which often reveals fat build-up. Once we understand the underlying issue, we explain your options and provide a transparent fixed-price quote.
For straightforward blockages, our high-pressure water jetting equipment clears most issues within an hour. For structural problems, we offer patch repairs that avoid expensive excavation. All work follows industry-standard methods aligned with WRc guidance and BS EN 752.
