Whether you’re preparing for a new patio, driveway or garden room, professional groundworks make the difference between a tidy finish and costly repairs. Our team works across CR4, including Mitcham Common and around Mitcham Junction station, delivering safe excavation, drainage and concrete bases. We handle everything from site clearance to levelling, so your build starts on stable ground. Expect clear communication, careful working and a site kept organised.
Mitcham’s mix of Victorian cottages, 1930s semis and modern estates often brings varied access and different sub-base requirements. Older homes can have shallow services, mature tree roots and tight side passages, while newer plots may need careful levels to manage surface water. We tailor foundations, retaining walls and drainage runs to suit the property and the intended load. If you’re upgrading a drive or extending, we’ll ensure the groundwork supports it properly from day one.
We start with a site visit to assess levels, soil, access and existing drainage, then provide a written scope and staged plan. Our process covers setting-out, excavation, spoil removal, sub-base installation, concrete work and tidy handover, with photos available for peace of mind. Homeowners choose us because we turn up when we say we will and keep neighbours in mind with considerate working. All qualifying groundwork is backed by our 10-year warranty.
Across the London Borough of Merton, access and parking can affect plant size, deliveries and spoil collection, so we plan logistics early. Around areas like Pollards Hill and Figges Marsh, we frequently work with sloping gardens and mixed ground conditions that demand careful levelling and compaction. We also take care around existing utilities and mature planting, especially near open spaces such as Mitcham Common. Where required, we coordinate with local guidance on drainage and crossover works.

Many domestic groundwork jobs in the Mitcham area take 1–5 days, such as clearance, excavation and levelling for a patio or driveway. Drainage upgrades and concrete bases often take 3–10 days depending on curing times and complexity. Larger foundation and retaining wall packages can run 2–4 weeks. Timescales are affected by access, weather, unexpected ground conditions, service locations and any inspections required.
Most garden groundworks are permitted development, but there are important exceptions. New or altered driveways may need to meet permeable surfacing rules, and changes near boundaries, highways or listed buildings can trigger permissions. Drainage connections and works affecting public footways or crossovers may require approvals. We’ll advise what’s likely needed for your project in the London Borough of Merton and can help you gather the right information before work starts.
Yes. Our qualifying groundwork is covered by a 10-year warranty for workmanship, including preparation, compaction, concrete bases and installed drainage lines where specified. The warranty is designed to protect you against defects caused by poor installation, such as settlement from inadequate sub-base or incorrect falls. It doesn’t cover damage from third-party works, severe ground movement beyond our control, or misuse/overloading beyond the agreed design. You’ll receive warranty details in writing.
We can build groundworks to suit a wide range of finishes and uses. Popular options include MOT Type 1 sub-bases for driveways, reinforced concrete slabs for garden rooms, soakaways and channel drains for surface water, and block or poured concrete retaining walls. We also form access roads and temporary haul routes where needed. We’ll help you choose the right specification based on levels, drainage needs, intended loads and your final landscaping design.
