If your lawn stays boggy after rain or water gathers by paving, a French drain can redirect it to a safe discharge point. Around Lee Green crossroads and Manor House Gardens, we often see gardens that hold water due to compacted ground and older drainage. Our systems use a gravel-filled trench with a perforated pipe to collect and carry water away. The result is firmer turf, fewer puddles and less risk of damp near the house.
Lee Green’s mix of Victorian terraces, Edwardian semis and 1930s houses often comes with narrow side access and established planting. We plan french drains Lee Green area installations to minimise disruption, protect borders and keep levels neat around patios and pathways. Where properties sit slightly lower than the street, we design the gradient to prevent backflow and surface pooling. We also work around existing soakaways, downpipes and garden structures to keep everything integrated.
Our process starts with a site survey, falls check and a clear drainage plan before any digging begins. We carry out trench excavation, lay geotextile membrane, install perforated pipe, then backfill with clean gravel for long-term performance. Every run is designed with the right gradient and a proper outlet connection, with options for multiple runs where needed. Homeowners choose Fine Landscaping for straightforward advice, tidy workmanship and a 10-year warranty for peace of mind.
In the London Borough of Lewisham, we regularly encounter heavy, compacted soils and gardens altered by past landscaping, which can slow natural drainage. Access can be tight near Lee station and around SE12 terraces, so we plan spoil removal and deliveries carefully. We also factor in parking constraints and protect existing paving and planting during excavation. Each design is tailored to your plot levels and the safest available discharge route.

Costs vary with length, depth, access and where the water can discharge. As a guide, smaller garden runs often start from around £900–£1,800, while longer systems with multiple runs, deeper excavation or new outlet connections can be £2,000–£5,000+. We’ll survey the site, confirm falls and provide a written estimate based on materials, spoil removal and reinstatement.
Most domestic installations take 1–2 days for a straightforward single run, including excavation, pipework, gravel fill and tidy-up. Larger gardens, multiple runs, deeper trenches or tricky access can extend the work to 3–5 days. Timescales also depend on locating services, weather conditions and whether we’re reinstating turf, borders, or paving after the drain is installed.
French drains in gardens are usually permitted development because they’re below ground and don’t change the building itself. However, rules can differ if you’re in a conservation area, working near protected trees, altering a driveway, or connecting to certain drainage systems. We’ll advise on the likely requirements and, where needed, help you check any relevant guidance for the London Borough of Lewisham before work starts.
