Chislehurst's varied terrain demands precision groundwork that respects both heritage properties and contemporary builds. From the Commons' edge to Elmstead Woods, every project starts beneath the surface.

Victorian villas perched on Chislehurst's slopes face unique challenges when foundations shift or drainage fails. Those grand period properties along Bromley Road weren't built with modern water tables in mind. Clay soil movement affects everything from conservatory bases to retaining walls, particularly during our increasingly unpredictable seasons.
Ground investigation reveals hidden stories - old wells beneath Edwardian gardens, forgotten cellars, Victorian soakaways still channeling water decades later. Modern solutions incorporate permeable surfaces meeting SuDS requirements whilst preserving mature root systems. Structural calculations account for London clay's notorious shrink-swell cycles, preventing future subsidence issues that plague BR7's hillside properties.
Local knowledge matters when excavating near Chislehurst Caves' network or managing water flow towards the Kyd Brook. Twenty years working these postcodes means understanding which properties sit on spring lines, where old pond sites create boggy conditions.

Drainage improvements typically range £3,000-£8,000, whilst underpinning Victorian bay windows starts around £15,000. Full driveway excavation and sub-base installation for those longer BR7 driveways usually sits between £12,000-£25,000.
Absolutely - from properties backing onto Scadbury Park through to homes near Elmstead Woods station. Regular projects in Mottingham and Sidcup too, particularly those tricky sloping sites near the A20.
Mini-piling work on a standard Victorian semi takes roughly two weeks, weather permitting. Simpler tasks like French drain installation around a detached property - usually 3-5 days start to finish.
All foundation work carries our decade-long structural warranty, backed by professional indemnity insurance. This covers both the physical work and any calculations provided by our structural engineer.
Directional drilling allows new drainage installation beneath mature borders without excavation. Where digging's unavoidable, we hand-dig around significant roots and replant immediately. Many Chislehurst gardens contain specimen trees worth protecting.
