Norbury's mix of Victorian terraces and post-war semis presents unique foundation challenges. From subsidence repairs on those steep Pollards Hill slopes to new-build footings navigating London clay, proper groundwork makes all the difference.
Response within 24 hours
Those familiar Norbury streets between Streatham High Road and Thornton Heath tell a story through their foundations. Victorian builders knew their craft, but time takes its toll - especially with our heavy clay soil shifting through wet winters and dry summers. Whether you're extending that 1930s semi or tackling basement conversion dreams, getting the footings right prevents decades of headaches.
Strip foundations suit most Norbury properties, but every plot has quirks. Tree roots from those mature plane trees along the main roads? Clay shrinkage near the railway embankments? Each demands specific engineering solutions. Modern ground beams and mini-piles solve problems our Victorian predecessors couldn't imagine, while proper waterproofing keeps those lower ground floors bone dry year-round.
Twenty years digging across SW16 teaches you which gardens hide old air raid shelters and where the clay turns to gravel. Local knowledge matters when you're three metres down and the building inspector's due tomorrow.

Single-storey rear extensions typically run £8,000-£15,000 for foundations, while full underpinning on a Victorian terrace might reach £25,000-£40,000. Those tricky sloping sites near Norbury Park often need engineered solutions adding 20-30% to standard costs.
Absolutely - from the conservation areas near Norbury station right through to the Thornton Heath borders. CR7 properties around Pollards Hill get the same attention as those closer to Streatham Common.
Standard extension footings take 2-3 weeks including inspections. Underpinning projects need 4-8 weeks depending on access - those narrow Victorian side returns always slow things down.
Every foundation carries our decade-long structural guarantee, backed by proper insurance. Building control sign-off comes standard, plus we photograph every stage - useful when you're selling years later.
