Victorian terraces in Wallington often hide foundation challenges that only reveal themselves during renovations. Whether you're extending towards Manor Road or excavating that sloped garden near Roundshaw, proper groundworks make all the difference.

Those Edwardian properties dotted around Woodcote Road weren't built with modern extensions in mind. Clay soil shifts, old chalk pits beneath Wallington mean your project needs someone who understands local ground conditions. Years of working between Carshalton's water meadows and Coulsdon's chalk hills taught us that SM6 postcodes demand specific expertise.
Excavation depth depends entirely on what lies beneath - sometimes it's London clay, other times Victorian rubble fill. Reinforced concrete foundations prevent future settlement issues, particularly important given Wallington's mix of soil types. Proper drainage channels protect against the area's surprisingly high water table, while careful grading ensures rainwater flows away from your property.
Every project from Stafford Road to Demesne Road gets the same meticulous attention. Local knowledge matters when you're digging near century-old sewers or navigating utility lines that weren't mapped properly.
Rated 4.9/5 from over 280 verified reviews
Extension foundations usually run £3,000-£5,000, though those narrow Victorian plots near the station might push costs higher. Full driveway excavation and preparation typically sits around £2,500-£4,000 depending on access.
Absolutely - from Hackbridge borders to Beddington Corner, including all those tucked-away crescents off Boundary Road. Regular work takes us through Purley and surrounding areas too.
Foundations need 48-72 hours minimum cure time, weather permitting. Most SM6 projects see builders on-site within a week of our completion.
Structural groundworks carry decade-long protection against settlement or failure. Documentation includes depth readings and photographic evidence - particularly useful for mortgage valuations.
Root protection zones get calculated before any digging starts. Those big oaks near Mellows Park aren't uncommon - special techniques preserve established trees while creating stable foundations nearby.
