If your lawn stays soggy after rain or water pools near the house, a properly built French drain can transform how your garden performs. Across Kingston upon Thames, we’re often called out for flooding around patios, side returns and low spots that never fully dry. From properties near Kingston Bridge to gardens off Surbiton’s residential streets, we design drains that quietly do the hard work underground. The result is firmer ground, fewer puddles and less risk to planting and paving.
Kingston’s mix of Victorian villas, Edwardian houses and modern waterfront apartments means drainage problems vary from plot to plot. Period homes can have tight side access and older ground levels that channel water towards the building, while newer developments may have compacted sub-bases that hold surface water. We regularly work across KT1 and KT2, tailoring trench routes and outlet positions to suit each layout. Our solutions are built to protect both garden usability and the fabric of the property.
We start with an on-site assessment, then set out a gradient design to ensure water flows to a safe discharge point. Installation typically includes trench excavation, geotextile membrane, gravel fill and a perforated pipe, finished neatly to blend with your garden. Where needed, we create multiple runs and connect to a suitable outlet connection such as a soakaway or existing surface water system (where permitted). Homeowners choose Fine Landscaping for clear workmanship standards, tidy sites and a 10-year warranty on our drainage installations.
The french drains Kingston upon Thames area needs are often shaped by compacted garden soils, mature tree roots and constrained access beside period homes. Parking and material drop-offs can be tricky near busy routes by the Bentall Centre, so we plan deliveries and spoil removal to minimise disruption. We also consider neighbouring boundaries, existing services and safe discharge options before any digging starts. Our method suits everything from narrow side passages to larger plots around Surbiton and New Malden.

Costs vary with length, depth, access and where the water can discharge. As a guide, small installations start from around £900–£1,800, while typical garden runs are often £2,000–£4,500. Larger systems with multiple runs, deeper trench excavation or new soakaways can reach £5,000–£8,500+. We’ll survey the site, confirm the gradient design and provide a detailed written quote before work begins.
Most French drain installations take 1–3 days, depending on trench length, ground conditions and access for excavation. A short run along a side return may be completed in a day, while gardens needing multiple runs, careful hand-digging around services, or new outlet connections can take longer. Weather, spoil removal logistics and making good lawns or borders also affect the schedule. We’ll confirm timings after the site visit.
In many cases, French drains in gardens are permitted development and don’t require planning permission. However, rules can change if you’re altering drainage to connect into public systems, working near protected trees, or the property is listed or in a conservation area. We’ll discuss your options, check practical compliance points and advise if you should contact the Royal Borough of Kingston upon Thames or a drainage professional for approvals before connecting any outlets.
Yes. We provide a 10-year warranty on our French drain installations, covering workmanship and the correct installation of key components such as the perforated pipe, gravel fill, geotextile membrane and connections. The warranty assumes normal use and reasonable maintenance, and it doesn’t cover damage caused by third-party works, ground movement from unrelated structural issues, or blocked outlets due to external debris. We also explain simple maintenance steps to keep performance high.
We tailor each system to the site. Options include different pipe diameters, clean stone grades for gravel fill, and heavier-duty geotextile membrane where silty soils are likely. Outlet choices can include a new soakaway, connection to an existing surface water line (where suitable), or routing to a lower area with controlled discharge. We can also add rodding points for easier maintenance. We’ll recommend the best combination after assessing levels, soil and access.
