Those grand Victorian terraces along Wimbledon Hill Road didn't stand the test of time by accident. Getting foundations right matters just as much today, whether you're adding that dream kitchen extension or finally building the garden studio.

Wimbledon's mix of London clay and sandy patches keeps foundation work interesting round here. From the period properties near the Common to newer builds in Raynes Park, each plot tells its own underground story. Local knowledge counts when you're digging down - knowing where the old chalk pits were, understanding how the water table shifts between seasons.
Strip foundations suit most SW19 extensions, running 450-600mm wide depending on your soil and load calculations. Raft foundations prove their worth on trickier plots where clay movement threatens standard strips. Mini-piles come into play near those magnificent oaks dotting Wimbledon Village - their roots demand respect and specialist techniques.
Twenty-three years working Wimbledon's varied terrain builds proper expertise. Every project gets Building Control approval sorted, structural calculations double-checked, neighbours kept happy throughout.

Strip foundations for a single-storey rear extension generally run £8,000-£12,000. Raft foundations start around £15,000, while mini-pile systems for challenging sites begin at £20,000. These figures include excavation, concrete, steel reinforcement and waterproofing.
Absolutely - from South Wimbledon's terraced streets to the larger plots around Copse Hill. Regular projects span both SW19 and SW20 postcodes, including Raynes Park's residential roads and properties backing onto Wimbledon Park itself.
Standard strip foundations take 2-3 weeks including excavation, concrete pour and curing time. Complex sites needing piles or special engineering might stretch to 4-5 weeks, particularly during wet winters when ground conditions slow progress.
Each foundation carries comprehensive 10-year structural warranty documentation. This covers the concrete work, steel reinforcement placement, and waterproof membranes - essentially everything below damp course level. Full certification provided for mortgage and insurance purposes.
Certainly - connecting new foundations to existing structures requires careful assessment and proper detailing. We'll arrange trial pits to check your current foundation depths, ensure adequate bearing capacity, and design appropriate connections that prevent differential settlement between old and new sections.
