If your lawn stays soggy or water pools after heavy rain, a properly designed French drain can make a dramatic difference. We install drainage systems across SW9, including homes near Stockwell tube station and Stockwell Park. By collecting groundwater below the surface and directing it to a suitable outlet, we help prevent muddy patches, slippery paths and water sitting against walls. The result is a garden that’s easier to use and maintain year-round.
Stockwell has a mix of Victorian terraces, Georgian houses and post-war estates, each with different drainage challenges. Narrow side returns, shared boundaries and compact rear gardens often call for careful access planning and precise trench excavation. We’re used to working around existing paving, patios and planted borders so disruption is kept to a minimum. Many clients in the french drains Stockwell area also want solutions that stay hidden and don’t spoil period features.
Our process starts with a site visit to confirm where water is collecting and where it can be discharged safely. We design the gradient, install a perforated pipe with gravel fill and a geotextile membrane, then connect to an appropriate outlet. Where needed, we can run multiple lines to capture water from different zones. Work is completed neatly, tested before we leave, and backed by clear aftercare guidance and a 10-year warranty.
In the London Borough of Lambeth, access and parking can be tight, especially on residential streets around Brixton and Oval. We plan material deliveries, spoil removal and trench routes to keep disruption down and protect existing finishes. Local gardens often have mixed ground made-up from past works, so we size gravel, pipe and membrane to suit and prevent fines migrating into the system. We’ll also advise on maintenance points so the drain stays easy to service.

Costs vary with length, depth, access and where the outlet can connect. As a guide, small runs for a typical rear garden might start around £1,200–£2,500, while longer or multiple-run systems with more excavation and reinstatement often fall in the £2,500–£6,000 range. If we need to break out and relay paving or route drainage through tight access, budgets can rise. We provide a written, itemised quote after a site survey.
Most single-run installations take 1–2 days, including trench excavation, pipe and gravel installation, membrane wrapping and reinstatement. Larger gardens, multiple runs, or complex outlet connections can take 3–5 days. Timescales depend on access (for example, narrow side passages), ground conditions, and how much paving or turf needs lifting and relaying. We’ll confirm a programme before starting and keep you updated if weather affects progress.
In many cases, French drains in gardens are permitted development and don’t need planning permission. However, rules can change if you’re working near a public highway, altering levels significantly, affecting shared drainage, or if the property is listed or in a conservation area. Lambeth may also have guidance on where water can be discharged, especially regarding surface water connections. We’ll check the practical and regulatory points and advise before any work begins.
We provide a 10-year warranty on our French drain installation workmanship, covering correct installation of the trench, membrane, gravel surround, perforated pipe runs, joints and outlet connections. The warranty is designed to give peace of mind that the system has been built to perform as intended. It doesn’t cover issues caused by external damage, building movement, or misuse (such as soil or cement washout entering the drain). We also explain simple maintenance to keep performance high.
We can tailor the design to your garden and the problem area. Options include different pipe diameters, rigid or flexible perforated pipe, varied gravel grades, and geotextile membrane specifications to suit silty ground. We can also add inspection/rodding points for easier maintenance, create multiple runs for split-level gardens, and connect to a soakaway or approved outlet where suitable. We’ll recommend the best combination after assessing falls, water volume and access constraints.
