Recent case study in Lewisham

Victorian Terrace CCTV Survey and Repair — Deptford. Problem: A pair of adjoining Victorian terraces in Deptford, Lewisham, shared a drain that was blocking every few weeks. The neighbours had an ongoing dispute about who should pay for repairs. Solution: We conducted a CCTV survey of the complete shared drain run and produced a written report showing the location and cause of all defects. The main blockage source was a displaced joint beneath the shared rear gate — clearly on the shared section adopted by Thames Water in 2011. We provided the report to Thames Water, who attended and carried out the repair under their adopted sewer obligations. Result: Thames Water repaired the displaced joint at no cost to either homeowner. The neighbour dispute was resolved. Both properties have had no further blockages.

Lewisham drainage FAQs

My Catford 1930s semi has a drain that backs up in heavy rain — what's causing it?

Drain backup during heavy rainfall in Catford is often related to the Ravensbourne river catchment. When the public sewers become surcharged in extreme rainfall events, the water can back up into private drainage connected to the same system. Thames Water operates a combined sewerage system in much of Lewisham. If this is a recurring problem, a check valve on your drain lateral can prevent sewer surcharge water from entering your property.

How quickly can you respond to a blocked drain in London?

How much does drain unblocking cost in London?

Drain unblocking costs in London typically range from £80–£250 for a standard residential blockage, depending on the severity and location of the blockage. We provide fixed-price quotes before work commences so there are no surprise charges. Emergency 24/7 call-outs may carry a premium over standard daytime rates.

Are you available 24 hours a day, 7 days a week?

What causes blocked drains in London?

The most common causes of blocked drains in London include: grease and fat build-up (fatbergs), root intrusion from London's many mature trees, collapsed or cracked Victorian clay pipes, flushed non-flushable items (wet wipes, cotton products), and ground movement from London Clay shrink-swell. London's Victorian drainage infrastructure is particularly susceptible to root infiltration and joint displacement.
