Those charming Edwardian properties around Cheam Village often hide foundation challenges that only reveal themselves decades later. Whether you're dealing with subsidence on London clay or planning an extension, getting the groundwork right matters more than any other aspect of your build.

Cheam's mixture of housing stock, from 1930s semis near the station to newer developments towards North Cheam, sits on notoriously tricky ground conditions. Clay shrinkage, tree root damage, and the occasional forgotten well can turn a straightforward project into something more complex. Having worked on dozens of properties between Cheam Common and Nonsuch Park, we've encountered pretty much every foundation scenario this area can throw up.
Modern foundation work goes well beyond simply digging trenches and pouring concrete. Ground investigation determines the exact approach needed - perhaps mini-piles where mature oaks line your boundary, or reinforced raft foundations where clay movement is a concern. Each property between Worcester Park Road and Sutton Common gets assessed individually, factoring in soil reports, nearby vegetation, and the specific loads your structure will impose.
Twenty years of local foundation work means knowing which structural engineers understand Cheam's ground conditions and which building control officers appreciate thorough documentation. Your neighbours won't appreciate foundation work dragging on, so efficiency matters as much as engineering excellence.

Basic strip foundations for a single-storey extension typically range from £8,000-£12,000, while underpinning a bay window might be £4,000-£6,000. Complex piled foundations for larger projects can reach £20,000-£30,000, though every quote reflects your specific ground conditions and structural requirements.
Absolutely - from the conservation areas around Cheam Village (SM3) to the residential streets near Sutton station (SM2), plus neighbouring areas like Ewell and Worcester Park. Most of our work stays within a three-mile radius of Cheam Broadway.
Strip foundations for an extension usually complete within 5-7 working days, weather permitting. Underpinning projects typically need 2-3 weeks, working in sections to maintain structural stability. Piled foundations might take 10-14 days including concrete curing time.
Every foundation project includes a 10-year insurance-backed guarantee covering both materials and workmanship. This transferable warranty gives peace of mind whether you're staying put or planning to move - crucial documentation for any future sale.
Definitely - we regularly tie new foundations into existing structures, ensuring proper integration without compromising either element. This often involves exposing the original footings, assessing their condition, and engineering a connection that accommodates any differential movement between old and new.
