If your garden stays soggy after rain or water pools near the house, a French drain can solve it without major disruption. We install systems across SE13, including streets around Hither Green station and the edges of Mountsfield Park. The aim is simple: intercept groundwater and guide it to a safe discharge point. You get a garden that’s usable sooner after downpours and less prone to moss and slip hazards.
Hither Green’s mix of Victorian terraces, Edwardian houses and 1930s semis often comes with compacted ground, older paths and limited side access. That combination can trap water against walls, under patios or along boundary lines. We plan routes that suit narrow passages, shared drains and existing landscaping. Our experience in the french drains hither green area means fewer surprises once excavation starts.
Every installation starts with a site check for levels, likely water paths and the best outlet connection. We then carry out trench excavation, set a consistent gradient design, lay perforated pipe, wrap with geotextile membrane and finish with clean gravel fill. Where needed, we build multiple runs to cover wider lawns or long rear gardens. Fine Landscaping backs workmanship with a 10-year warranty and provides straightforward maintenance guidance.
In the London Borough of Lewisham, we often see heavy, compacted soils and gardens shaped by extensions and outbuildings. Access can be tight around terraces near Lee and Lewisham, so we plan spoil removal, parking and deliveries to minimise disruption. We also check existing gullies and shared drainage routes before choosing an outlet. The result is a system that suits local property layouts and typical rainfall patterns.

Costs vary with trench length, depth, access, and where the outlet can connect. As a guide, smaller installations for a side return or short run often start around £900–£1,800. Medium garden systems are commonly £1,800–£3,500, while larger or multi-run solutions can be £3,500–£6,500+. We’ll confirm a range after checking levels, ground conditions and reinstatement needs.
Most domestic French drain installs take 1–3 days, depending on length, depth and how easy it is to access the garden. A short run with a straightforward outlet may be completed in a day. Longer trenches, multiple runs, or careful work around patios, services and planting can extend the programme. Wet weather, clay soils and disposal logistics also affect timings, but we’ll set expectations before starting.
In many cases, French drains in gardens are permitted development because they’re below ground and don’t materially change the building. However, rules can differ if you’re in a conservation area, altering a driveway, or discharging water to a public sewer. We’ll advise on suitable soakaway or gully connections and help you avoid directing water onto neighbouring land. If approvals are needed, we’ll flag them early.
We provide a 10-year warranty on our French drain workmanship, covering correct installation of the trench, membrane, gravel, pipework and connections. It’s designed to give peace of mind that the system will perform as intended when used and maintained properly. The warranty doesn’t cover damage from third-party building works, tree root intrusion from unmanaged growth, or blocked outlets caused by neglect, but we’ll explain maintenance clearly.
We can tailor the design to your garden and the problem area. Options include different pipe diameters, rigid or flexible perforated pipe, varying gravel grades, and full geotextile wrap to reduce silting. We also design single runs for borders or walls, or multiple runs for wide lawns and persistent waterlogging. Outlet options may include a soakaway, existing gully connection, or a new discharge point where appropriate.
