Those Earlsfield clay soils shifting beneath your Victorian terrace? Years of tackling SW18's unique ground conditions have taught us exactly what works here – from reinforced foundations to clever drainage systems that actually last.
Response within 24 hours
Earlsfield's mix of period properties and newer developments each bring their own ground-level challenges. Victorian houses along Magdalen Road often need underpinning work, whilst the newer builds near Garratt Lane frequently require proper drainage retrofitting. Having dug into hundreds of local gardens, we've seen how the London clay beneath SW18 behaves through every season.
Proper groundworks start with understanding what lies beneath. Bore samples reveal soil composition, water table levels, and any historic disturbance from old foundations or Victorian wells. Modern techniques like mini-piling provide stability without the disruption of traditional methods – particularly useful when working between Earlsfield's closely-packed houses. Ground-source heat pump installations have become increasingly popular here, requiring precise excavation work that preserves existing landscaping.
Local knowledge matters when you're digging near century-old sewers and forgotten Anderson shelters. Every Earlsfield project benefits from our decade-long relationship with SW18's utility companies and planning officers.
Rated 4.9/5 from over 280 verified reviews
Basic drainage improvements start around £3,500, whilst full driveway excavation and sub-base installation typically ranges £8,000-£15,000 for standard Earlsfield plots. Underpinning work varies considerably based on depth and access.
Absolutely – from the conservation areas near Wandsworth Common through to the busier streets around Earlsfield station. We're equally comfortable working on Southfields' wider plots or Tooting's compact Victorian gardens.
Drainage solutions typically wrap up within 5-7 days, whilst comprehensive driveway groundworks usually span 2-3 weeks including excavation, sub-base installation and compaction stages.
Each groundworks project carries our decade-long guarantee covering structural integrity and drainage performance. This includes annual inspections for the first two years, giving peace of mind that your investment remains sound.
Definitely – Earlsfield's established plane trees and complex underground services require careful planning. Ground radar surveys map existing pipes and cables, whilst root protection zones ensure trees remain healthy throughout excavation work.
