Those charming Victorian terraces in Balham weren't built with modern living in mind. Whether you're extending upwards, outwards, or tackling that persistent damp in your cellar, solid groundworks make all the difference.

Balham's mix of period properties and newer developments throws up some interesting challenges beneath the surface. Clay soil shifts, ageing drainage systems struggle, and those narrow access routes between terraced houses need careful navigation. Years of working across SW12 have taught us every quirk of the local ground conditions - from the high water table near Wandsworth Common to the tricky soil composition around Balham High Road.
Modern groundworks go far beyond simple excavation. Underpinning Victorian foundations requires precision engineering to support additional storeys. Contemporary drainage solutions protect basements from south London's unpredictable rainfall patterns. Each project starts with thorough site analysis, considering everything from neighbouring properties to existing utilities running beneath those busy Balham streets.
Local knowledge counts when you're digging beneath SW12. Every street has its own underground story, and we've learned them through decades of careful work. Trust comes from consistently delivering projects that stand the test of time - and Balham's weather.

Victorian terrace extensions in SW12 usually require £8,000-£15,000 for groundworks, though basement conversions can reach £25,000-£40,000 depending on depth and waterproofing requirements. Smaller projects like patio bases start around £3,000.
Absolutely - from Balham Station down to Tooting Bec Common, across to Nightingale Triangle and up towards Clapham South. Those tight Victorian streets don't phase our compact equipment.
Simple foundation work typically completes within 5-7 days. Basement excavations need 3-4 weeks, while drainage overhauls usually wrap up in under a fortnight. Weather permitting, naturally.
Every structural element carries decade-long coverage against settlement or failure. Documentation includes detailed specifications, perfect for mortgage lenders or future property sales. Peace of mind runs deep.
Those magnificent London planes need respect. Root protection zones guide our excavation methods, often using hand-digging near established trees. Local conservation rules around protected species? We handle the paperwork too.
