Those Edwardian semis along Stafford Road weren't built on guesswork. Neither should your extension be. Working across SM6's mix of chalk and London clay requires specific expertise - something we've developed through hundreds of local projects. From single-storey kitchen extensions to complete rebuilds, the right foundation transforms ambitious plans into solid reality.
Strip foundations suit most Wallington properties, though raft designs work brilliantly where gardens slope towards Carshalton. Depth calculations factor in nearby trees - those mature oaks common in Coulsdon can demand deeper excavation. Ground conditions dictate everything: we'll assess soil type, water table levels, and structural loads before breaking ground. Modern reinforcement techniques mean even challenging plots become buildable.
Twenty years digging through SM6's varied geology teaches you plenty. Local building control know us well - inspections run smoothly when paperwork's spot on.

Standard strip foundations for a 4x5m extension generally run £4,000-£6,500. Larger projects or tricky ground conditions push costs higher - we'll survey first and quote accurately.
Absolutely - SM6 forms our core area, extending through Carshalton, Purley and Coulsdon. Local knowledge matters when dealing with area-specific ground conditions.
Most domestic foundations take 5-8 working days, weather permitting. Complex designs or poor ground might extend this - we'll provide realistic schedules after site assessment.
Every foundation carries our decade-long structural warranty. This covers settlement issues and structural integrity - proper peace of mind for such crucial work.
Certainly - lightweight structures need different calculations than brick-built extensions. We regularly prepare bases for timber frames, steel structures and modern garden offices throughout Wallington.
