Keston's chalk downland presents unique challenges when laying foundations for your property. Whether you're extending a period home near the Common or starting fresh on one of those generous plots off Heathfield Road, getting the groundwork right is everything.

Foundation work in BR2 requires intimate knowledge of local ground conditions. From the clay pockets near Holwood to the chalk seams running through central Keston, every site tells a different story. Years of working beneath properties from Victorian villas to 1960s estates have taught us exactly what each area demands. Those spacious gardens backing onto woodland might look perfect for an extension, but understanding water table variations between seasons makes all the difference.
Strip foundations, raft systems, or piled solutions - the right choice depends entirely on your specific plot. Clay shrinkage affects many properties near Lakes Road differently than homes on the higher ground towards Farnborough. Modern building control requirements mean deeper excavations than older properties needed, particularly where mature oaks and chestnuts have established root systems. Ground heave prevention becomes critical when removing established vegetation, something we factor into every calculation.
Local knowledge beats textbook theory every time in Keston. Having poured concrete for neighbours' extensions probably visible from your garden, we understand how BR2's terrain behaves through drought and deluge alike.

Single-storey rear extensions typically range £8,000-£15,000 for foundations, though properties near the Common with challenging access might reach £20,000. Two-storey additions generally start around £15,000.
Absolutely - from the Locksbottom borders to properties adjoining Hayes Common. Regular projects span Keston Mark to Leaves Green, including those tricky sloped sites near Downe.
Excavation through concrete pour usually completes within 5-8 working days. Allow three weeks total including building control inspections and cure time before loading.
Every foundation carries decade-long structural coverage backed by professional indemnity insurance. This encompasses settlement issues, concrete integrity, and waterproofing membrane performance throughout the guarantee period.
Rarely suitable unfortunately - most conservatory slabs lack adequate depth or reinforcement for loadbearing walls. However, partial underpinning sometimes allows integration, saving demolition costs while meeting current regulations.
