Those steep Victorian garden slopes in Putney need proper groundwork before any landscaping begins. From basement excavations to retaining walls, the right foundation transforms challenging plots into usable outdoor spaces.
Response within 24 hours
Putney's mix of period properties and riverside developments throws up unique groundwork challenges. Clay soil near the Thames, mature tree roots from Victorian plantings, and those characteristic sloping gardens all demand specialist knowledge. Years of working between Putney Bridge and East Putney station have taught us exactly how local ground conditions behave through the seasons.
Proper drainage ranks as the make-or-break element for SW15 gardens. Surface water rushes down from Putney Heath, while clay beneath holds moisture like a sponge. Installing French drains, soakaways and permeable surfaces prevents that familiar winter bog effect. Retaining walls need calculating precisely - too shallow and frost will shift them within two winters.
Local contractors understand Putney's planning quirks and conservation area restrictions. Working alongside structural engineers familiar with Thames-side subsidence patterns means getting it right first time.

Standard Victorian terrace plots (6m x 15m) usually require £4,000-£8,000 for comprehensive levelling and drainage. Larger detached properties near Putney Heath often need £12,000-£20,000, especially with significant slope correction.
All of SW15 falls within our regular working area - from the riverside properties near Putney Embankment to the larger plots up towards Roehampton Lane. Barnes and Putney Heath jobs fit naturally into our schedule too.
Smaller terraced gardens typically complete within 8-10 working days. Properties with extensive excavation or multiple retaining walls might stretch to 3-4 weeks, weather permitting.
All retaining walls, drainage systems and foundation work carry decade-long protection against structural failure. Documentation includes engineer calculations and photographic evidence of each construction stage.
Absolutely - persistent wet patches usually stem from compacted subsoil or inadequate drainage. Strategic installation of land drains connected to soakaways resolves most water retention issues, particularly common in lower Putney's clay areas.
