Those cramped Victorian gardens in SW18 deserve solid foundations before any landscaping begins. Garden groundworks transform waterlogged patches behind Wandsworth terraces into spaces ready for whatever you envision.

Wandsworth's clay-heavy soil poses particular challenges when laying patios or installing drainage systems. Years of tackling soggy lawns between Southfields and Earlsfield taught us which excavation depths work best here. Victorian properties often hide old soakaways or forgotten foundations that need careful navigation during groundwork preparation.
Proper excavation depth prevents future subsidence, especially crucial given SW18's notorious ground movement issues. Compacted hardcore bases create stability beneath patios, while French drains redirect water away from house foundations. Smart grading angles ensure rainfall flows toward planted borders rather than pooling against back doors - essential with Wandsworth's unpredictable weather patterns.
Local knowledge matters when digging near century-old boundary walls or navigating narrow side returns typical of Battersea conversions. Every project receives the same meticulous attention, whether preparing ground for a compact courtyard or excavating an entire rear garden.
Rated 4.9/5 from over 280 verified reviews
Most SW18 Victorian terrace gardens (roughly 30-40sqm) require £2,500-£4,500 for comprehensive groundworks including excavation, drainage, and sub-base preparation. Larger double-fronted properties near Wandsworth Common might reach £6,000-£8,000.
Absolutely - from the Tonsley estate across to Wandsworth Town station, including all residential streets between Garratt Lane and the River Wandle. Regular projects in Southfields and Earlsfield too.
Standard terrace gardens need 3-5 working days for complete groundworks. Drainage installations or extensive levelling might extend this to 7-10 days, weather permitting.
All structural groundworks carry decade-long protection against settlement or drainage failure. This covers the sub-base integrity, compaction standards, and any installed drainage systems - documented with photographic evidence throughout the process.
Definitely - poor drainage causes most SW18 lawn issues. Installing land drains at strategic depths, combined with soil improvement and proper grading, transforms boggy gardens into useable spaces year-round. Sometimes adding a soakaway resolves decades of water-logging problems.
