Gardens across Carshalton present unique challenges for shed placement – from sloping plots near Carshalton Beeches to clay-heavy soil common throughout SM5. A properly constructed base transforms these obstacles into opportunities for secure garden storage.
Response within 24 hours
Victorian terraces around Carshalton High Street often feature narrow gardens where every square metre counts. Modern shed bases maximise usable space whilst ensuring your garden building remains level year-round. Local knowledge of drainage patterns and ground conditions throughout SM5 means foundations that work with, not against, your specific plot.
Concrete pours require precise timing, especially given Carshalton's variable weather patterns. Reinforced mesh strengthens the slab, while proper membrane installation prevents moisture damage from below. Each base incorporates slight gradients for water runoff – essential given the area's clay substrate which retains surface water longer than sandy soils found elsewhere.
Twenty years installing bases across Wallington, Hackbridge and central Sutton brings insight no newcomer possesses. SM5 residents regularly recommend our work because foundations laid properly today prevent costly remedial work tomorrow.

Standard 8x6ft bases generally range £450-650, though sloping gardens near Carshalton Park may require additional groundwork. Larger 12x10ft installations typically fall between £750-950, with exact costs determined by access and soil conditions.
Absolutely – from The Wrythe through to Carshalton Village, including all residential areas bounded by Sutton and Wallington. Regular projects span from Ruskin Road to Stanley Park.
Concrete bases need 48-72 hours before bearing weight, though full curing takes approximately one week. Paving slab alternatives can support lighter structures immediately after completion.
Each installation carries decade-long protection against structural failure, covering both materials and workmanship. This encompasses settlement issues, cracking, and water ingress through the base structure.
Many Carshalton properties feature old patios suitable for conversion. Assessment checks load-bearing capacity and drainage – often minor adjustments create ideal shed platforms without complete reconstruction.
