Hammersmith’s Victorian terraces are closely built and often extended, so reaching the drain can be the hardest part of the job.
The terraces of Brackenbury Village, Ravenscourt Park and the streets off the Broadway were built close together with small yards and narrow side returns, and the drainage runs through them accordingly. Inspection chambers end up under decking, inside kitchen extensions, beneath patios and occasionally under a neighbour’s paving. Before anything can be cleared it has to be reached, and in W6 that is often the part that takes the time. A camera survey confirms where the runs actually go.
Many of these houses have also been extended or had basements dug out. Side-return kitchen extensions are common on these terraces and often go over the original drain run. Basement conversions add pumped drainage below the level of the sewer, which introduces sump pumps and non-return valves, all components that fail and that leave a basement with no drainage at all when they do.
Extensions and patios covering the only access. Locating and reaching the chamber is often the bulk of the job.
Side-return kitchens often sit over the original clay drain. Lining is often the most practical repair.
Below-sewer basements depend on pumps. When one fails there is no gravity fallback and the basement can flood.

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.

Leaks, taps, traps, toilet cisterns and waste pipes: the plumbing that often comes with a drainage job.
Common questions about drainage in Hammersmith, answered for the kind of property you find there.
Usually. In W6 it is common, because side-return extensions have often been built over the original drain runs. There is normally another access point upstream or downstream we can work from, and a camera will confirm the layout. Where a run genuinely has no access at all, adding a new access point is sometimes the sensible long-term answer.
Not necessarily. A below-sewer basement drains through a pump and a non-return valve, and if the valve has jammed open the main drain can back up into the basement during heavy rain when the system is under load. That looks like a blockage but is a valve failure. Both are worth checking.
