What we see most often in SW London homes

The housing stock across SW, KT, SM and TW postcodes is a mix of Victorian terraces, 1930s semis, mansion blocks and newer flats — each with its own recurring faults. These are the ones we attend most often:

• Victorian and Edwardian terraces in SW postcodes often have older soil stacks, awkward access, and legacy pipework that blocks with wipes, scale, and fat more easily than modern plastic systems.
• Mansion blocks and converted flats in areas like Wandsworth, Putney, Wimbledon, and Richmond often have low-flow fixtures and long shared runs that make slow drainage and intermittent blockages more likely.
• 1960s ex-local-authority flats in KT, SM, and TW often share stacks and laterals, so one flat’s blockage can affect several units and needs coordinated access.
• Hard-water scale from the Thames Water area can build up inside pipework and traps, narrowing flow and contributing to repeat blockages.
• Tree roots entering older clay or pitch-fibre drains are a recurring issue in leafy South West London streets and gardens, especially where original drainage is still in place.
• Kitchen fat, wet wipes, and food waste are common causes of repeat blockages in mixed residential blocks and HMOs with shared kitchens or heavy occupancy.

Brands and parts we work with

We carry common-fault parts on the van for the brands found in most SW London properties, so most jobs are resolved on the first visit.

DIY or call a pro?

Honest guidance — sometimes a YouTube tutorial is enough, sometimes calling us is the cheaper option once you factor in damage and time.

• DIY is usually safe for a slow sink, bath, or shower trap if you can isolate water, remove the trap, and clear visible debris.
• DIY is not ideal for repeat blockages, foul smells from multiple fixtures, or water backing up into more than one appliance, because that usually means a deeper drain issue.
• Call a pro for any blockage in the soil stack, external drain, shared stack, or outside chamber, especially in flats and maisonettes.
• Use a qualified drainage engineer for CCTV surveys, jetting, root ingress, or suspected collapsed pipework.
• If the problem involves gas appliances, boiler condensate, or buried pipework around a gas meter, use a Gas Safe engineer or the correct specialist rather than general DIY.

How the job runs, from call to invoice

1. 11. The contractor takes your postcode, symptoms, and whether the blockage affects one fixture or several.
2. 22. On arrival, they inspect the affected area, test flow, and identify likely access points such as a trap, rodding eye, or external chamber.
3. 33. They give a written or verbal quote before starting, including any extra cost for jetting, CCTV, or difficult access.
4. 44. They clear the blockage using rodding, plunging, mechanical cleaning, or high-pressure jetting as needed.
5. 55. They retest the flow at the fixture and, if relevant, check upstream and downstream drains for recurrence.
6. 66. They tidy the work area, explain the cause, and flag any defects such as broken pipework or root ingress.
7. 77. They issue the invoice with labour, any parts used, and notes for follow-up if further investigation is recommended.
