If your garden holds water after rain, the problem is usually poor falls, compacted ground or blocked outfalls. Our drainage team works across SE11, including streets near The Oval cricket ground and Oval tube station. We pinpoint where water is collecting and route it away safely using proven systems. The result is a garden that’s usable sooner after downpours and kinder to planting.
Oval’s Georgian townhouses, Victorian terraces and mansion flats often come with narrow side returns, courtyards and long rear gardens where water can get trapped. Older paving and clay-heavy subsoils can worsen surface run-off, especially where previous landscaping has reduced permeability. We tailor solutions for the garden drainage Oval area, whether it’s a small patio by Kennington Park or a deeper lawn plot towards Vauxhall. Every design is sized to your roof run-off, hardstanding and ground conditions.
We start with a site assessment and, where needed, CCTV surveys to confirm pipe routes and identify breaks or silted sections. Then we specify the right combination of grading, catch pits, land drains, soakaways or pump systems, with clear options and costs before work begins. Installations are completed with careful reinstatement of lawns, paving and borders, and we pressure-test flows where applicable. Homeowners choose us for reliable communication, neat finishes and drainage that performs year-round.
Working in the London Borough of Lambeth means factoring in tight access, controlled parking and shared boundaries common to terraces. We plan spoil removal, deliveries and working hours to suit residential streets around Kennington and Stockwell. Ground conditions can vary from compacted made-ground to heavier clay, so we combine grading with land drains or soakaways as needed. Where gravity falls are limited, we design pump-assisted systems with accessible service points.

Costs depend on the cause of flooding, access, and how much reinstatement is required. As a guide, small fixes such as a short channel drain or local regrading may start around £750–£1,500. French drains and catch pits for a typical rear garden are often £1,800–£4,500. Larger schemes with soakaways, multiple runs, or pump systems can be £4,500–£9,000+. We provide a site-specific written estimate.
Most garden drainage jobs take 1–3 days, such as installing a French drain run with a catch pit and reinstating a lawn edge. More complex projects—multiple land drains, a soakaway, or significant grading—typically take 3–7 days. Timescales vary with access through terraced houses, the amount of excavation, weather, and whether we’re lifting and relaying paving. We’ll confirm a programme before starting.
Garden drainage is usually permitted development because it’s below ground and doesn’t change the building’s footprint. However, rules can apply if you’re altering hardstanding, working near party walls, connecting to existing drains, or if the property is listed or in a conservation area. We’ll advise on best practice for managing run-off and will check any Lambeth requirements before excavation. If permissions are needed, we can help you prepare the details.
We provide a 10-year warranty on our drainage installation workmanship, covering issues such as failed joints, incorrect falls, or defective installation of components we supply and fit. The warranty applies when the system is used as designed and not damaged by later building works or root intrusion beyond reasonable control. We also explain maintenance points, such as clearing silt traps and inspecting catch pits, to keep performance consistent.
Options include French drains with clean stone and geotextile, perforated land drains, channel drains with galvanised or polymer grates, and soakaways using modular crates or traditional rubble. Catch pits and silt traps can be added for easier maintenance, and pump systems are available where gravity drainage isn’t possible. We’ll recommend the best combination based on your soil, levels, garden layout and finish preferences, including discreet placement to protect planting and paving.
