Those beautiful Victorian terraces around Streatham Common often hide a frustrating secret - gardens that stay waterlogged for weeks. Clay soil, common across SW16 and SW2, holds water like a sponge, creating muddy patches that ruin lawn parties and leave garden furniture sinking. Professional drainage tackles this at the root, channeling excess water away before it becomes a problem.
Modern drainage systems blend French drains, soakaways, and strategic grading to manage water flow naturally. Each Streatham garden needs its own approach - what works for a sloped plot near Tooting Bec Common won't suit the flatter gardens towards Norbury. Perforated pipes laid in gravel trenches capture surface water, while deeper channels intercept groundwater before it saturates your lawn.
Having installed drainage across hundreds of Streatham gardens since 2014, we understand the quirks of local soil conditions. Every installation comes with detailed plans showing exactly where your new drainage runs, making future landscaping projects straightforward.

Absolutely - from the busy streets near Streatham station to the quieter roads around Furzedown recreation ground. Regular projects span both SW16 and SW2 postcodes, including Streatham Vale and the conservation areas.
A typical Streatham garden takes 3-5 days from start to finish, including excavation and reinstatement. Larger properties or complex systems might need a full week, especially if we're working around mature trees.
Each drainage installation carries a decade-long guarantee covering both materials and workmanship. Should any issues arise with water flow or system performance during those ten years, repairs are handled at no charge.
Careful excavation preserves most established plants, though some temporary disruption is inevitable. Lawns are reinstated with fresh turf or seed, typically recovering within 4-6 weeks. Mature shrubs and trees are protected throughout the process.
