From garden transformations to extension prep, our team delivers professional groundwork that sets your project up for success. We work across DA14 and DA15, including jobs near Sidcup High Street and Foots Cray Meadows. Expect tidy site clearance, accurate excavation and levels, and robust bases built to spec. Every stage is planned to protect your property and keep disruption manageable.
Sidcup’s housing mix calls for flexible, experienced groundworks. We regularly support 1930s semis with tight side access, Victorian houses needing careful excavation around existing structures, and modern developments where drainage and falls must be spot-on. Whether you’re in Foots Cray or close to Chislehurst, we tailor methods and machinery to suit the plot. The result is groundwork that supports patios, driveways, walls and buildings for years.
We start with a site visit to assess levels, access and drainage routes, then provide a clear written scope. Our process covers levelling, foundations, concrete work, retaining walls and access roads, with quality checks at each milestone. Homeowners choose us for straightforward communication, clean working practices and dependable scheduling. You also get workmanship backed by a 10-year warranty for peace of mind.
As groundwork contractors in London Borough of Bexley, we plan around local access constraints, parking, and skip placement—common on residential streets in Sidcup. Ground conditions can vary between established gardens and newer plots, so we assess bearing capacity and drainage needs before digging. We also factor in nearby trees, existing services and boundary walls to avoid surprises. Where required, we align our work with council guidance and building control expectations.

Costs depend on access, depth of excavation, spoil removal and the specification. As a guide, small site clearance and levelling may start from £800–£2,000. Concrete bases for sheds/outbuildings are often £1,200–£3,000, while larger foundation and drainage packages for extensions can range from £5,000–£15,000+. We’ll survey your Sidcup property and provide an itemised estimate.
Timescales vary by scope and weather. Simple clearance, excavation and levelling can take 1–3 days. A concrete base with drainage adjustments is commonly 3–7 days, including curing time planning. Larger jobs—foundations, retaining walls and access roads—often run 2–4 weeks. The biggest factors are access for machinery, the amount of spoil to remove, and any unexpected services or ground conditions.
Many garden and driveway groundworks fall under permitted development, but there are important exceptions. New or altered driveways may need compliant permeable surfacing or drainage to a suitable soakaway, and works near boundaries or affecting levels can trigger rules. If your project links to an extension, building regulations inspections may also apply. We’ll advise early and can help you check requirements with the London Borough of Bexley.
We provide a 10-year warranty on workmanship for our groundworks, covering issues such as settlement caused by installation faults, poor compaction, and defects in installed concrete or drainage runs (where included in our scope). Materials are supplied to manufacturer standards and carry their own guarantees where applicable. We also document what’s been installed and how, so you have clear records for future maintenance or property sales.
We can build bases and sub-bases for block paving, resin-bound surfaces, tarmac, porcelain patios, and natural stone. For drainage, options include soakaways, channel drains, ACO systems and permeable sub-bases. Retaining walls can be constructed in concrete block, brick to match your home, or engineered systems depending on height and loading. We’ll recommend options based on your Sidcup plot, budget, and the finish you want.
