Crystal Palace's hillside terrain and Victorian housing stock demand foundations built to last generations. From period property underpinning to modern extension groundwork, precision matters when working with South London's challenging clay soils.

Those steep slopes around Westow Hill aren't just scenic—they create unique structural challenges for properties throughout SE19 and SE20. Victorian terraces perched on Crystal Palace's ridgelines need foundations that work harder than most. Whether you're planning an ambitious basement conversion or addressing subsidence in your Anerley semi, proper groundwork forms the backbone of any successful project.
Modern foundation engineering goes far beyond simply pouring concrete into trenches. Ground movement monitoring, reinforcement calculations, and drainage integration all play crucial roles in creating structures that withstand decades of London clay expansion and contraction. Depth requirements vary dramatically across Upper Norwood's undulating landscape—what works near the park might fail completely on Church Road's steeper sections.
Twenty-three years tackling Crystal Palace's trickiest plots builds genuine expertise. Local structural engineers regularly refer complex cases our way, knowing we understand this area's geological quirks intimately.
Rated 4.9/5 from over 280 verified reviews
Basic strip foundations for smaller extensions start around £8,000-12,000, while full underpinning projects for Victorian properties typically range £25,000-45,000. Basement excavations in SE19's hillside locations often exceed £60,000 due to retaining wall requirements.
Absolutely—from Gipsy Hill's conservation areas to Penge's newer developments. Regular work takes us across both SE19 and SE20 postcodes, including tricky access sites near Sydenham Hill station.
Concrete curing varies with weather, but expect 2-3 weeks minimum before loading. Full foundation projects including excavation typically complete within 4-6 weeks, weather permitting.
Each project receives comprehensive ten-year structural coverage, backed by independent insurance. This includes protection against settlement, heave, and any workmanship defects that might emerge over time.
Yes, navigating party wall procedures is standard practice here. We coordinate with surveyors, maintain detailed condition records, and ensure neighbours' properties remain protected throughout excavation work.
