Those Victorian terraces along Mitcham Road didn't build themselves on solid ground by accident. Getting the foundations right matters just as much today when you're extending that Tooting property or sorting out subsidence issues.

Tooting's mix of London clay and occasional gravel pockets keeps foundation work interesting round here. Whether it's underpinning a period property near Tooting Bec Common or laying footings for a rear extension, the ground conditions between Furzedown and Tooting Broadway vary more than you'd think. Local knowledge counts when you're digging below those narrow Victorian garden plots.
Strip foundations suit most Tooting extensions, typically going down 1.2 metres through the clay. Pile foundations become necessary where trees have dried out the soil or where old bomb damage left unstable ground - surprisingly common near the Northern Line. Modern building regs demand proper calculations for load-bearing capacity, plus we always check for old wells and Victorian soakaways that crop up in SW17 gardens.

Single-storey rear extension footings generally run £3,500-£5,500 including excavation and concrete. Underpinning starts around £15,000 for a bay window, climbing to £30,000+ for a full side wall.
Absolutely - from the Broadway shops to the quieter streets near Furzedown Rec. We've dug foundations in most roads between Tooting Bec tube and Mitcham Lane over the years.
Strip footings for extensions take 5-8 working days including inspections. Underpinning projects stretch to 3-5 weeks depending on access through those narrow Tooting side returns.
Every foundation carries decade-long structural coverage backed by proper insurance. The warranty documentation satisfies building control and mortgage lenders - crucial for SW17's competitive property market.
Definitely - most Tooting foundation projects need party wall notices. We coordinate with surveyors and photograph neighbouring properties beforehand, keeping everyone happy when excavating close to boundaries.
