If puddles linger after rain or your patio stays slick for days, a properly designed French drain can transform how your garden performs. We install drainage systems across SW18, including routes that discreetly run along fences, borders and side passages. Many call us after issues near Wimbledon Park or around Southfields tube station where heavy downpours expose weak drainage. Our goal is simple: capture surface and groundwater and send it safely to an approved outlet.
Southfields homes often have compact rear gardens and narrow access, especially around Victorian terraces and Edwardian houses. We also work regularly on 1930s semis where lawns can sit lower than the patio, encouraging water to pool against the house. In the french drains Southfields area, we frequently see clay-heavy ground that holds moisture and causes soggy borders. Our designs suit the property layout, protecting foundations while keeping the garden usable year-round.
We start with a site survey, levels check and a clear plan for gradient design and outlet connection. Installation includes trench excavation, geotextile membrane, a perforated pipe bedded in clean gravel fill, then a tidy finish to match your garden. Where needed, we create multiple runs to intercept water from problem zones and connect to suitable discharge points. Homeowners trust us for clean workmanship, straightforward communication, and a 10-year warranty on our installation.
In the London Borough of Wandsworth, gardens often combine clay subsoil with compacted ground from years of use, which slows soakaway. Access can be tight near the Southfields Grid and parking restrictions may apply, so we plan deliveries and waste removal carefully. We adapt trench widths and spoil management to protect paths, planting and neighbouring boundaries. Our french drains in London Borough of Wandsworth are installed with practical outlets and service access for future maintenance.

Costs vary with length, depth, access and where the outlet can connect. As a guide, small problem areas might start around £900–£1,800, while longer runs across a rear garden are often £2,000–£4,500. Complex jobs with multiple runs, deeper trench excavation, or tricky spoil removal can be £5,000+. We provide a written, itemised quote after checking levels and discharge options.
Most installations take 1–3 days, depending on the run length and how easily we can access the garden. A straightforward single run along a border may be completed in a day, while multiple runs with careful reinstatement can take longer. Timescales are affected by ground conditions, depth required for correct gradient design, and whether we need to route pipework to a specific outlet connection point.
French drains within a private garden are usually permitted development and don’t need planning permission. However, rules can change if you’re in a conservation area, altering levels near boundaries, or connecting to certain drainage systems. Discharging water onto the highway is not allowed, and connections to public sewers must be compliant. We check practical options on-site and advise on any council or building control considerations before work begins.
Yes. We provide a 10-year warranty on our French drain installation workmanship, covering issues such as failed joints, incorrect falls, or installation defects that affect performance. The warranty applies when the system is used as designed and not damaged by later building works. We also explain simple maintenance steps, like keeping inlets clear and avoiding soil wash-in, to help the drain perform reliably for years.
We tailor the design to your garden and water source. Options include different pipe diameters, clean angular gravel grades, and heavier-duty geotextile membrane where silt is an issue. We can add inspection points for easier maintenance, create multiple runs to intercept water from several areas, and choose finishes such as turf, gravel strips or discreet planting cover. We’ll recommend the best combination after measuring levels and testing ground conditions.
