Those charming period properties along Westwood Hill face persistent water issues, particularly where original drainage has deteriorated over decades. Clay-heavy soil throughout SE26 compounds the problem, preventing natural absorption after heavy rainfall. French drains offer a discreet solution, channeling excess water away from vulnerable areas without disrupting your garden's appearance. Many Sydenham residents discover this simple intervention saves thousands in future repair costs.
Installation begins with careful gradient assessment – crucial given Sydenham's varied topography between Crystal Palace Park and lower Bell Green. Perforated pipes wrapped in geotextile fabric prevent soil infiltration whilst maintaining water flow. Strategic placement around property perimeters, beneath patios, or across problematic lawn areas creates an invisible network managing surface water year-round. The system connects to existing soakaways or storm drains, ensuring compliance with local water authority regulations.
Twenty years handling Sydenham's drainage quirks means recognising issues specific to different streets and property types. From Edwardian semis near Mayow Park to newer developments towards Forest Hill, each project receives tailored planning based on genuine local knowledge.

Basic systems start around £85 per linear metre, though Victorian properties with complex layouts typically range £2,500-£4,500 total. Factors include access difficulties, depth requirements, and connection points to existing drainage.
Absolutely – from properties backing onto Sydenham Woods through to homes near Lower Sydenham station. Regular projects include addresses along Jews Walk, Venner Road, and the conservation areas around Sydenham Park.
Most residential French drain installations complete within 3-5 days, weather permitting. Immediate water diversion begins upon pipe placement, though full effectiveness develops as surrounding soil adjusts over following weeks.
Every French drain system includes decade-long protection covering both materials and workmanship. This comprehensive warranty reflects confidence in proper installation techniques and premium-grade components selected specifically for SE26's soil conditions.
Exterior French drains significantly reduce hydrostatic pressure against basement walls, often eliminating penetrating damp. Combined with proper tanking, they're particularly effective for Victorian cellars common throughout Sydenham's conservation areas.
