If your garden holds water after rain, a properly designed French drain can relieve the pressure and prevent recurring soggy patches. In SE19, slopes and run-off around Crystal Palace Park and Westow Park can push water towards patios and lower ground. Our drains capture groundwater in a gravel-filled trench and carry it to a safe outlet. The result is a garden that drains quickly and stays usable year-round.
Upper Norwood’s Victorian villas, Edwardian houses and period conversions often have mature gardens, retaining walls and older surface levels that weren’t built with modern drainage in mind. We regularly see water tracking along side returns, pooling by steps, or seeping into lower-ground rooms. With experience across the french drains Upper Norwood area, we tailor the layout to tight side access and shared boundaries. Every design is planned to protect planting and preserve the character of period properties.
We start with a site assessment, identify the water’s route, then set a precise gradient design so the system actually carries water away. Installation includes trench excavation, geotextile membrane, perforated pipe, washed gravel fill and a reliable outlet connection. Where needed, we add multiple runs to intercept water from different directions. Work is kept tidy, surfaces are reinstated neatly, and we explain simple maintenance to keep performance consistent.
Upper Norwood’s hilltop setting means water can move quickly downslope and collect at pinch points near walls and paved areas. Access can be narrow on period plots, so we plan spoil removal, parking and materials delivery to suit the street. For french drains in London Borough of Croydon, we also consider where discharge is permitted and keep outlets discreet. Our approach balances effective drainage with the look of older gardens and stone or brick edging.

Costs vary with length, depth, access and how many runs are needed. As a guide, smaller installations often start around £900–£1,800, while longer or multi-run systems with deeper excavation and more reinstatement are commonly £2,000–£4,500+. Difficult access, extra spoil removal, and complex outlet connections can increase costs. We’ll survey your SE19 site and provide a clear, itemised estimate.
Most domestic French drain installations take 1–3 days, depending on trench length, depth, and whether you need multiple runs. Jobs with tight side access, extensive paving to lift and reinstate, or a long route to the discharge point can take longer. Weather and ground conditions also affect progress. After the survey, we’ll confirm a realistic schedule and keep disruption to a minimum.
In many cases, garden drainage works such as French drains are permitted and don’t require planning permission. However, rules can change if you’re altering levels significantly, working near protected trees, or your property is listed or within a conservation area. Discharging water must also be done responsibly and legally. We’ll advise on the likely requirements and help you check any Croydon-specific constraints before work starts.
