Those Victorian terraces along Main Road weren't built with modern rainfall patterns in mind. Clay soil meeting concrete drives equals drainage nightmares - but there's a surprisingly elegant fix hiding underground.

Biggin Hill's elevation brings proper downpours, and that water needs somewhere to go. Traditional drains struggle here, especially where older properties meet newer extensions and patios. A properly designed soakaway quietly handles thousands of litres, keeping foundations dry and gardens usable year-round.
Modern crate systems beat the old rubble pits hands down. Calculate the catchment area, factor in TN16's notorious clay content, then size accordingly - usually bigger than homeowners expect. Percolation tests reveal exactly how stubbornly your particular patch resists drainage. Sometimes combining with permeable surfaces transforms a boggy disaster into functional space.
Twelve years solving drainage puzzles across the hill means knowing which corners flood first come autumn. Every installation carries decade-long protection because shortcuts show up fast when winter arrives.

Basic residential soakaways start around £1,200, though challenging clay or limited access pushes toward £2,500. Larger properties needing multiple units or connection to existing systems typically land between £3,000-£4,500.
Absolutely - from Keston's leafy lanes to Westerham's older estates, plus Tatsfield's rural properties. The whole TN16 postcode sees regular visits from our drainage team.
Standard installations wrap up within 2-3 days, weather permitting. Complex systems linking multiple downpipes might stretch to 4-5 days, but we section work to maintain access throughout.
Each installation includes ten-year coverage against defects - rare given proper sizing and quality materials. Annual checks catch potential issues before they escalate, keeping that warranty valid through the decade.
Additional roof area definitely needs factoring in - sometimes enlarging existing systems works, other times a secondary soakaway makes more sense. Site assessment reveals the most cost-effective approach for your specific layout.
