Those Victorian terrace gardens in Clapham deserve foundations as solid as the houses they complement. From excavating waterlogged clay to installing proper drainage systems, groundworks form the backbone of any lasting garden transformation.
Response within 24 hours
Clapham's mix of period properties and modern developments throws up unique challenges when tackling garden projects. Clay soil that turns to soup in winter, restricted access through narrow side returns, and the occasional discovery of Victorian foundations all require careful planning. Whether you're levelling that sloping plot near Clapham Common or addressing persistent flooding issues in your Battersea-borders garden, proper groundworks make the difference between a quick fix and a permanent solution.
Breaking ground involves more than just shifting earth. Soil analysis determines drainage requirements, while careful excavation preserves existing root systems and underground services. Modern soakaway systems handle SW4's notorious surface water issues effectively, whilst retaining walls maximise useable space on those characteristic sloped plots. Each stage builds upon the previous, creating stable foundations for patios, pathways and planting areas that won't sink, crack or flood come the first heavy rainfall.
Twenty years of digging through South London's varied geology teaches you which shortcuts lead to callbacks. Local knowledge matters when you're navigating Thames clay one street and sandy deposits the next.

Basic levelling and drainage for a typical 8m x 15m Victorian terrace garden runs £3,000-£5,000. More complex projects involving retaining walls or extensive excavation range from £7,000-£15,000 depending on access and soil conditions.
Absolutely - from the grand gardens overlooking Clapham Common to compact courtyards in Stockwell, we work across SW4 and SW11. This includes Battersea borders, Abbeville Village and everywhere between.
Most residential groundworks complete within 5-10 working days. Concrete bases need 48 hours before loading, while compacted sub-bases can take immediate installation of paving or decking.
All structural groundworks carry our decade-long guarantee. This covers settlement issues, drainage failures and any defects in retaining structures - basically everything below ground level for ten full years.
Preservation of established plants guides every excavation. Root protection zones are mapped and respected, while hand-digging near valuable specimens ensures minimal disturbance. Many Clapham gardens feature century-old trees that become focal points rather than obstacles.
