Recent case study in Greenwich

Pre-Purchase Survey — Georgian Property, Greenwich Town. Problem: A purchaser of a Georgian end-of-terrace in Greenwich town wanted a drain survey before buying. The property was Grade II listed with no permitted development rights, so any future drainage works would need listed-building consent — a strong reason to know exactly what condition the drains were in before exchange. Solution: CCTV survey found the 100mm clay main drain to be in reasonable condition for its age, with minor root intrusion at one joint, some scale build-up throughout, and a hairline crack on one section beneath the front path. Recommendations: one-off jetting and root-cutting clearance to clear the joint intrusion, no immediate structural repairs required, monitor the hairline crack on a 5-year re-survey cycle. Result: Buyer proceeded with purchase with confidence and a written WRCm-standard report on file. The jetting clearance was carried out at £250 on completion day. Eighteen months later we returned to fit a check valve in the basement after a tidal-surge event highlighted the property's lower-ground vulnerability — a single-day £450 retrofit that has prevented two further tidal-surge incidents since.

"Had a CCTV survey before buying our Victorian terrace. Found a cracked pipe section that the seller's surveyor had missed. Saved us thousands in unexpected repairs. Report was clear and detailed with video footage."

James T. — Dulwich, South London
★★★★★

"Our kitchen drain had been slow for months. The jetting completely cleared years of grease buildup. Engineer also gave us good advice on preventing it happening again. Very happy with the service."

Greenwich drainage FAQs

I live near Greenwich Park — does the park cause drain problems?

Properties adjacent to Greenwich Park can experience root infiltration from the park's mature trees, including large oaks and chestnuts. The park trees have had centuries to establish deep, extensive root systems. If your property backs onto or faces Greenwich Park, a periodic CCTV survey of your drain run is advisable, as root infiltration may be present even before it causes a complete blockage.

Does the tidal Thames affect drains in Greenwich Peninsula and Charlton riverside properties?

Yes — Greenwich is one of London's higher-risk boroughs for tidal flood interaction. Properties at lower-ground or basement level on the Greenwich Peninsula, in Charlton riverside, in parts of Woolwich and in Thamesmead can experience combined-sewer surcharge during spring high tides combined with heavy rainfall. The standard fix is a non-return (check) valve on the affected lateral — a one-day retrofit that eliminates tidal backup. Annual function testing of any existing valve is worth scheduling. The Environment Agency's long-term flood risk service has property-level mapping for the borough.

Why do drains on Shooters Hill, Blackheath and Eltham slopes need different treatment?

The steep gradients off Shooters Hill, Blackheath and the Eltham high ground produce very fast pipe flows — sometimes over 4 m/s where the standard design target is around 0.75 m/s. Fast flows scour clay pipe joints, accelerate aggregate erosion in older drains, and concentrate root intrusion at the toe of the slope where the gradient flattens. The most common visible symptom is a recurring blockage 20–40 metres downhill of an otherwise clear drain run. The right approach is a CCTV survey to identify the displacement point, followed by no-dig pipe relining of the affected section — rather than another round of rodding that won't address the underlying gradient issue.

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

We aim to reach most London addresses within 60-90 minutes for emergency call-outs. For non-emergency bookings, same-day appointments are often available. Response times can vary slightly in outer London boroughs during peak traffic hours.

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.
