If your lawn stays waterlogged or rain pools by the patio, a French drain can move water away fast and quietly. We design and install systems across Eastfields, including around Eastfields station and the SW16/CR4 borders. By combining correct gradient design with a clean outlet connection, we reduce standing water and protect planting beds. The result is a garden that’s usable sooner after downpours.
Homes here range from Victorian terraces to 1930s semis and newer developments, and each brings different drainage challenges. Narrow side returns, shared boundaries and older garden levels can make surface water linger. Our team is five minutes away, so we can assess conditions quickly and plan practical access for materials and spoil removal. We tailor french drains Eastfields area installations to the layout of your plot, not a one-size-fits-all trench.
We start with a site survey, then set out the run(s) and falls before trench excavation begins. Each drain is built with a geotextile membrane, gravel fill and perforated pipe, then connected to a suitable discharge point. Where needed, we install multiple runs to capture water from wider lawns or long boundaries. Homeowners choose us for tidy workmanship, clear communication, and a 10-year warranty on our installation.
Eastfields gardens often have compact access and mixed ground made up of disturbed soils from past landscaping. We plan spoil removal, parking and deliveries to minimise disruption on residential streets near Figges Marsh and Mitcham. Our outlet options take account of existing gullies and levels so water moves away safely. We also build with maintenance in mind, keeping key points accessible for future checks.

Costs vary with length, depth, access and where we can discharge the water. As a guide, smaller installations for a short run along a patio edge often start around £900–£1,800. Medium garden systems with longer trenches and an outlet connection are commonly £1,800–£3,500. Complex jobs with multiple runs, deeper excavation or difficult access can be £3,500–£6,000+. We’ll survey and provide a detailed written quote.
Most single-run French drains take 1–2 days from set-out to reinstatement, depending on length and digging conditions. Larger gardens or multiple runs typically take 2–4 days. Timescales can increase if access is tight (common with terraces), if we need to break out hardstanding, or if the outlet connection requires additional groundwork. We’ll confirm a schedule before starting and keep disruption as low as possible.
In many cases, French drains installed within a private garden are permitted development and don’t need planning permission. However, rules can change if you’re altering levels significantly, working near a public highway, or your property has restrictions (for example, certain new-build conditions). Drainage must also discharge appropriately and not cause issues for neighbours. We’ll advise on likely requirements and can help you check any Merton-specific constraints before work begins.
Yes. We provide a 10-year warranty covering our workmanship and the correct installation of the system (including trench excavation, membrane placement, gravel fill, pipe laying and connections). The warranty is designed to give peace of mind that the drain is built to specification and will perform as intended. It doesn’t cover blockages caused by misuse or external factors such as tree root ingress where roots were not present at installation. We also explain straightforward maintenance to protect performance.
We can tailor the design to your garden and the problem area. Options include different pipe diameters, gravel grades, and geotextile membrane types to suit soil conditions and expected flow. We can run the drain along boundaries, behind retaining edges, or as multiple runs feeding into a main line. Outlet choices may include connection to an existing gully or a suitable soakaway where feasible. We’ll recommend the best combination after assessing levels, access and discharge options for french drains in London Borough of Merton.
