Chelsea gardens can hold water after heavy rain, leaving lawns spongy and paving slick. Our team installs discreet drainage solutions near King’s Road properties and around SW3 and SW10 homes where runoff and compacted ground are common. A properly built French drain captures water below the surface and channels it away before it reaches basements or lower-ground rooms. The result is a drier garden and fewer issues with algae, puddling and damp edges.
We work across the french drains Chelsea area, including South Kensington, Fulham and Pimlico, where access can be tight and finishes must suit premium landscaping. Many clients live in Georgian townhouses, Victorian mansions and luxury apartments with courtyard gardens, roof terraces or narrow side returns. These spaces often need careful trench excavation and tidy reinstatement to protect stone paving, brickwork and planting. We plan routes that respect existing services, tree roots and heritage details.
Our process starts with a site survey to map water flow, levels and likely outlet options. We then complete gradient design, trench excavation, geotextile membrane lining, gravel fill and perforated pipe installation, with multiple runs where needed. Every system is tested before we make good, and we explain maintenance so performance stays consistent year after year. Homeowners choose us for clear communication, clean workmanship and a 10-year warranty on installation.
In the Royal Borough of Kensington and Chelsea, we often find compacted subsoil and hard landscaping that pushes water towards buildings. Chelsea streets near Stamford Bridge can also present restricted access, timed deliveries and controlled parking, so we plan logistics before excavation begins. We design routes that suit narrow side passages and basement lightwells, and we keep disruption low for neighbours. Where required, we can coordinate with your managing agent for luxury apartment blocks.

Costs in Chelsea vary mainly by length, depth, access, and the number of runs needed. As a guide, smaller installations for a side return or courtyard garden often start around £1,200–£2,500. Medium projects for a typical rear garden commonly fall between £2,500–£6,000. Complex drainage with multiple runs, deeper excavations, or difficult access can be £6,000–£12,000+. We provide a detailed, itemised quote after a survey.
Most French drain installations take 1–3 days on site, depending on trench length, depth, and how easily we can remove spoil and deliver gravel. A short run with a straightforward outlet may be completed in a day, while larger gardens or multiple runs typically need two or three. Timescales can extend if we must work around existing services, protect premium paving, or coordinate access and parking restrictions in SW3/SW10.
In many cases, French drains within a private garden are permitted and don’t require planning permission. However, rules can change if your property is listed, within a conservation area, or if works affect boundaries, shared walls, or drainage connections. If the outlet links to existing surface water systems, we also check the appropriate connection method. We’ll advise on any RBKC considerations during the survey and can help you gather the right approvals if needed.
Yes. We provide a 10-year warranty on our French drain installation workmanship, covering issues such as incorrect falls, failed connections, or installation defects that affect performance. The warranty assumes normal use and that the system isn’t damaged by later building works, root intrusion from new planting, or blocked outlets caused by external debris. We also explain simple maintenance steps, such as checking inspection points and keeping outlet grilles clear, to protect long-term flow.
We tailor the design to your garden and finish requirements. Options include different perforated pipe diameters, clean angular gravel grades for better void space, and robust geotextile membranes to limit silt migration. We can add multiple runs, connect to a soakaway or suitable surface water outlet, and include access points for easier maintenance. Where aesthetics matter, we can finish with turf, gravel, or discreet channel details to suit high-end Chelsea landscaping.
