Groundworks are the part you don’t see, but they decide how well everything performs for years. Our team prepares sites across Cheam Village and around Nonsuch Park, dealing with tight side access, mixed ground and existing services. From excavation and foundations to drainage runs and concrete bases, we coordinate each stage so your project can progress without delays. We also build retaining walls and access roads where plots need extra support.
Cheam’s mix of period cottages, 1930s houses and executive homes often brings different challenges underfoot. Older properties in SM2 and SM3 can have shallow existing footings, legacy drains and mature tree roots that need careful protection. In North Cheam and Worcester Park, we regularly work on driveway rebuilds, garden re-levels and extension bases where keeping disruption low matters. You get practical advice on levels, falls and build-ups that suit your home and budget.
We start with a site visit, utility checks and a clear scope of works, then plan spoil removal, deliveries and safe access. Every job is completed to specification, with tidy working practices and full public liability insurance. We document key stages (dig depth, sub-base, reinforcement, drainage falls) so you know what’s been done. Homeowners choose our groundwork contractors Cheam area service for straight answers, dependable scheduling and durable results.
As groundwork contractors in London Borough of Sutton, we plan around residential parking restrictions, school-run traffic and narrow access common near conservation streets. We assess soil conditions and existing drainage before setting levels, especially on sloping gardens close to Cheam Recreation Ground. Where trees or older services are present, we adjust excavation methods and protection measures. The result is compliant groundwork that suits Cheam’s varied property styles.
Rated 4.9/5 from over 280 verified reviews
Costs vary by access, spoil removal, dig depth and whether you need drainage or concrete. As a guide in Cheam, site clearance and excavation often starts from £800–£2,500. Foundations for an extension commonly range £4,000–£12,000 depending on size and depth. Drainage installations are typically £1,200–£4,500, while concrete bases can be £90–£160 per m² plus preparation.
Small jobs such as levelling, a short drainage run or localised concrete work can take 1–3 days. Typical driveway groundworks are often 3–7 days, depending on excavation volume and curing time. Extension foundations frequently take 1–2 weeks including inspections and concrete set. Timescales are affected by access restrictions, weather, hidden obstructions, and whether additional retaining walls or service diversions are required.
Many garden and driveway groundworks are permitted development, but there are important exceptions. New or altered driveways may need compliant permeable surfacing or drainage to a soakaway, and work near boundaries can be affected by levels and retaining structures. If your home is near a conservation area around Cheam Village, extra considerations may apply. We’ll flag likely permissions, coordinate inspections where needed, and keep the build compliant.
We provide a 10-year warranty on our workmanship for qualifying groundwork projects, covering issues arising from installation defects such as sub-base failure, incorrect falls to drainage, or concrete base problems. Materials are covered by relevant manufacturer guarantees where applicable. The warranty assumes normal use and that later works don’t disturb the installed groundworks. We also keep records of key stages so any future queries can be handled quickly.
We tailor the build-up to what you’re constructing: MOT Type 1 sub-bases, reinforced concrete slabs, trench-fill or traditional foundations, and drainage using uPVC or clay connections as required. For retaining walls we can build with concrete blocks, reinforced concrete, or sleeper-style solutions where suitable. We’ll advise on levels, falls, access road make-up and edging details, then specify the best option for durability, budget and finish.
