If your garden stays soggy after rain, a properly built French drain can make a dramatic difference. We install drainage systems across CR2, including homes near South Croydon station and around Lloyd Park. Our drains intercept groundwater and redirect it to a suitable outlet, helping prevent puddling on lawns and water pooling by patios. The result is a garden you can actually use, even through wet spells.
South Croydon is known for leafy streets, excellent schools and generous plots, but many properties still suffer from poor garden falls and compacted ground. We regularly work on large detached houses, 1930s semis and Victorian villas in Sanderstead, Purley and nearby Croydon. These homes often have mature planting, terraces and retaining edges that need careful drainage planning. We tailor each layout to the site, not a one-size-fits-all trench.
Our process starts with a site survey to identify the source of water and the best route for discharge. We then carry out trench excavation, install a perforated pipe with the correct gradient design, wrap with a geotextile membrane, and backfill with clean gravel. Where needed, we run multiple lines to cover wider lawns or problem borders, and we keep reinstatement tidy. Homeowners choose Fine Landscaping for clear communication, reliable scheduling and a 10-year warranty on our drainage installation.
Across the London Borough of Croydon, gardens often combine sloping ground with compacted subsoil and heavy rainfall run-off from hardstanding. In the french drains South Croydon area, access can be tight on driveways and side passages, so we plan spoil removal, deliveries and parking to minimise disruption. We also consider mature trees and root zones, especially near green spaces like Croham Hurst Woods. Every outlet connection is chosen to be safe, compliant and practical for the property.

Costs vary with length, depth, access and where we can discharge water. As a guide, small domestic runs often start from around £900–£1,800, while longer or deeper installations with multiple runs and more excavation commonly fall between £2,000–£5,500+. If an outlet connection needs additional pipework, soakaway work or reinstatement to paving, that can increase the budget. We provide a written quotation after a site visit.
Most residential installs take 1–3 days, depending on trench length, depth and how many runs are required. Straightforward lawn trenches with good access are usually completed in a day. Jobs can take longer where we’re working around patios, steps, retaining edges or tight side access, or where we need to form a new outlet connection. Weather, ground conditions and reinstatement requirements also affect timescales.
In many cases, French drains within a private garden are permitted and don’t require planning permission. However, rules can change if you’re altering levels significantly, working near a boundary, or connecting to certain drainage systems. If your property is listed or in a conservation area, extra checks may apply. We’ll advise during the survey and, where needed, help you confirm requirements with the London Borough of Croydon.
Yes. We provide a 10-year warranty on our French drain installation workmanship, covering correct installation of the trench, membrane, gravel fill, perforated pipe and connections as specified. It’s designed to give you confidence that the system will perform as intended when maintained properly. The warranty doesn’t cover damage from third-party works, severe ground movement, or blockages caused by misuse, but we’ll always advise on prevention and maintenance.
We can tailor the system to your garden and budget, including different pipe diameters, gravel grades and trench widths. Options include fully wrapped pipe “socks”, heavier-duty geotextile membranes for silty ground, and inspection points for easier maintenance. We can also design multiple runs feeding a main line, or combine drainage with a discreet gravel strip. If discharge is limited, we’ll discuss alternatives such as soakaways or improved surface falls.
