If your garden holds water after rain, a properly designed French drain can transform how it performs year-round. In Twickenham, we often see pooling near patios and side returns, especially around St Margarets and the streets leading towards Twickenham Stadium. Our drains capture surface water and relieve saturated ground without changing the look of your outdoor space. The result is firmer lawns, drier borders and fewer muddy patches.
Local homes in TW1 and TW2 range from Victorian villas and Edwardian houses to 1930s family homes with generous rear gardens. These properties commonly have older hard landscaping, compacted sub-bases and narrow access routes that make drainage upgrades tricky. We plan excavation and spoil removal to suit tight side passages and established planting. Where needed, we can run multiple lines to protect both lawn areas and paved zones.
Every installation starts with a site survey to confirm where water collects and where it can safely discharge. We set the correct falls (gradient design), excavate a neat trench, line it with geotextile membrane, install perforated pipe, then backfill with graded gravel. Finally, we connect to a suitable outlet and reinstate surfaces cleanly. Fine Landscaping is based in Norbury and typically reaches Twickenham in around 45 minutes, with clear communication, tidy working and a 10-year workmanship warranty.
Twickenham gardens can combine compacted ground, mature roots and mixed soil layers that slow drainage after downpours. Parking and access can be limited near Richmond and Teddington, so we schedule deliveries and spoil removal to minimise disruption. We also factor in older boundary walls, shallow services and existing paving levels common in period streets. Our approach keeps falls accurate and reinstatement neat, while meeting practical local constraints.

Costs depend on length, depth, access and the outlet option. As a guide, smaller runs for a side return or patio edge often start around £900–£1,800. Typical garden installations with 10–20 metres of trenching and reinstatement commonly fall between £2,000–£4,500. Larger schemes with multiple runs, deeper excavation or complex outlet connections can be £5,000+. We provide a site-specific written estimate after surveying.
Most French drain installations take 1–3 days on site, depending on the run length and how much reinstatement is required. A short trench with straightforward gravel fill and a nearby outlet can be completed in a day. Longer runs, multiple lines, or careful work around patios, planting and narrow access routes can take longer. Weather, ground conditions and service locations also affect the programme.
In many cases, French drains within a private garden are classed as permitted development and won’t need planning permission. However, rules can change if you’re altering levels significantly, working near a listed building, or within a conservation area (common around historic pockets near Strawberry Hill). If the outlet connects to an existing surface water system, we also check what’s allowed. We’ll advise during the survey and help you stay compliant.
Yes. We provide a 10-year workmanship warranty on our French drain installations, covering correct installation of the trench, membrane, pipework, gravel fill and connections. It’s designed to give confidence that the system has been built to perform as intended. The warranty doesn’t cover damage from third-party works, accidental impact, or blockages caused by misuse (for example, soil washed into open gullies). We also offer maintenance advice to keep flow clear.
We tailor each system to the site. Options include different pipe diameters, gravel grades, and whether to use a single run or multiple runs to cover wider lawns. We always use a geotextile membrane to reduce silt ingress, and we can incorporate inspection points for easier maintenance. Outlet choices may include a soakaway (where suitable), connection to an existing surface water line, or discharge to a safe drainage point. We’ll recommend the best layout after assessing levels and water flow.
