Standing water ruining your Clapham garden? Those Victorian clay soils beneath SW4 and SW11 properties weren't designed for modern drainage demands.
Response within 24 hours
Period properties across Clapham Common struggle with drainage more than most realise. Clay-heavy ground, combined with original Victorian guttering systems, creates perfect conditions for waterlogging. Installing a French drain system transforms soggy lawns into usable spaces, particularly crucial given the premium on outdoor space in this part of South London.
Modern French drains work by intercepting groundwater before it becomes a problem. Perforated pipes wrapped in geotextile fabric sit within gravel-filled trenches, channeling excess water away from foundations and gardens. Depth varies between 600mm and 1200mm depending on your specific water table - something we determine through proper site assessment rather than guesswork.
Twenty years solving drainage issues between Stockwell and Battersea means understanding local soil conditions intimately. Every installation carries proper certification and connects to approved soakaways or storm drains.
Rated 4.9/5 from over 280 verified reviews
Most Clapham properties require £2,800-£5,500 for comprehensive French drainage, though larger Victorian plots occasionally reach £7,000 depending on access difficulties and trench lengths needed.
Absolutely - from Clapham Old Town through to Battersea Rise, including all properties within SW4 and SW11 postcodes plus neighbouring Stockwell addresses.
Standard residential installations complete within 3-5 days, weather permitting. Complex systems involving multiple properties or extensive landscaping restoration might extend to 7-10 days.
Each French drain system includes decade-long protection covering materials and workmanship, with annual inspection options available for complete peace of mind.
Careful routing minimises disruption to mature planting. Where trenches must pass near roots, hand-digging preserves valuable specimens whilst achieving proper drainage depths.
