Teddington Lock marks the tidal limit of the Thames, and being near the river can affect how a property’s drains behave.
Below the lock the river rises and falls with the tide; above it the level is held. Near the river on either side, groundwater can work into open joints, leaving drains part-full and silt returning after each clearance.
The housing is largely Victorian and Edwardian terrace and villa, with substantial interwar building out towards Fulwell. Both eras used clay with mortar joints, and both have had long enough for those joints to open. Many Teddington gardens are long, so the runs between house and boundary chamber are long, and roots from the mature trees that make the area attractive have plenty of pipe to find, which a camera survey will pick up.
Close to the Thames, groundwater can get into open joints and keep drains part-full.
Silt that returns after every clearance points at infiltration through a defect rather than at usage.
Long gardens mean a lot of pipe between house and boundary, and plenty of opportunity for root ingress.
This page covers Teddington and Fulwell (TW11, TW12). If your postcode is on the edge of this area, call and ask rather than assuming.
Call and speak to the engineer. 24 hours a day, including tonight.
Sinks, toilets, gullies and main drains cleared, with the cause identified rather than guessed.
Overflowing gullies and blocked manholes or inspection chambers, cleared and explained.
Toilets that will not flush, or that fill up and will not drain, cleared without damaging the pan or the soil pipe.
Kitchen sinks and waste pipes blocked with grease, cleared properly rather than just poked through.
Standing water in the bath or shower tray, and slow bathroom basins, cleared at the cause.
Sewage backing up, drains overflowing, or a home or business you cannot use until it is fixed. Phone answered 24/7.
Scours grease, silt, scale and roots off the pipe wall, rather than just making a hole through the blockage.
See the inside of the pipe: recurring blockages, pre-purchase checks, insurance and subsidence claims.
Cracked joints, root damage and collapsed sections, repaired without digging where the pipe allows.
Restaurants, pubs, offices, landlords and managing agents: planned maintenance and out-of-hours call-outs.
Leaks, taps, traps, toilet cisterns and waste pipes: the plumbing that often comes with a drainage job.
Common questions about drainage in Teddington, answered for the kind of property you find there.
It can. Below the lock the river is tidal, so water levels change through the day; above it the level is held. On either side, a drain near the river with an open joint can take in groundwater, run part-full and silt up, and sealing the joint is what stops it.
It changes what can reach the problem. Rods have limited reach and struggle with bends, so on a long garden run they may not reach the blockage at all. Jetting travels much further and cleans the pipe wall on the way, and a camera then confirms what is actually down there rather than leaving it to guesswork.
