From Keston Common to the lanes leading towards Hayes, projects here often start with careful preparation below ground. Our groundwork team delivers site clearance, excavation, levelling and concrete work to create a stable base for patios, driveways, extensions and garden structures. We plan access, spoil removal and deliveries so your property stays protected and tidy. If you’re in BR2, we can survey and advise quickly.
Keston’s mix of period cottages, large detached houses and country homes often comes with mature gardens, sloping plots and older drainage runs. We’re used to working around established trees, boundary walls and tight side access, particularly on properties heading towards Farnborough and Downe. Whether you need new foundations for an outbuilding or a retaining wall to create usable terraces, we design the groundwork to suit the site. Every build starts with understanding what’s already in the ground.
Our process is straightforward: site visit, measured plan, clear scope of works, then phased groundwork with regular updates. We prioritise safe excavations, correct falls for drainage, and properly compacted sub-bases before any surfacing goes down. Homeowners choose us for reliable scheduling and workmanship that doesn’t cut corners. You’ll also get a 10-year warranty on qualifying groundwork installations for peace of mind.
As groundwork contractors in the Keston area, we plan for narrow access, on-street parking constraints and careful protection of verges and boundaries. We also factor in local ground conditions that can vary across the London Borough of Bromley, especially on larger plots with mature landscaping. Where required, we coordinate drainage connections and ensure falls work with existing runs. Our approach keeps your project compliant, practical and built for the long term.

Costs depend on access, excavation volume, disposal, and what’s being built. As a guide in BR2, site clearance and levelling might start from £800–£2,500, while excavation and sub-base preparation for a driveway or patio often falls around £2,500–£8,000. Drainage upgrades commonly range £1,200–£6,000. Foundations and reinforced concrete work can be £3,500–£15,000+, depending on depth and specification.
Small jobs such as localised excavation, levelling or a short drainage run can take 1–3 days. A full groundwork package for a driveway base, patio build-up and drainage commonly takes 1–2 weeks. Foundations for an outbuilding or extension are often 3–7 working days, depending on curing time and inspections. Timescales vary with access, weather, unexpected services, and the amount of spoil to remove.
Many garden groundwork projects are permitted development, such as replacing a patio or preparing a base, provided you’re not significantly altering levels near boundaries or affecting drainage to the highway. Driveways can require specific surfacing and drainage rules, especially for front gardens. Retaining walls, major level changes and works near protected trees can trigger permissions or conditions. We’ll advise early and help you check Bromley requirements before work begins.
We provide a 10-year warranty on qualifying groundwork installations, covering workmanship and structural integrity of items such as sub-bases, concrete slabs, foundations, retaining walls and installed drainage runs. The warranty applies when the work is completed to the agreed specification and maintained appropriately. We also document what’s been installed (depths, materials and falls where relevant) so you have a clear record for future works or property sales.
We tailor the build-up to your finish and site conditions. Options include Type 1 MOT sub-bases, reinforced concrete slabs, permeable sub-base systems for driveways, and French drains or channel drains for surface water control. For retaining walls, we can build in concrete blocks, brick to match your home, or engineered sleepers where suitable. We’ll recommend the right specification after assessing levels, loading and drainage needs.
