Mayfair gardens often sit behind tight access routes and premium façades, so ground preparation must be precise and discreet. We deliver site clearance, excavation, levelling and grading that set the right levels for patios, lawns, planting and outdoor structures. Working near Berkeley Square and Mount Street, we plan logistics to minimise disruption. Every job includes responsible waste removal and clear communication from start to finish.
Local properties range from Georgian mansions and palatial townhouses to luxury apartments with courtyard gardens. These spaces can hide old foundations, mixed made ground and legacy drainage that needs upgrading before any landscape build. Our garden groundworks Mayfair area service is designed to protect period features while modernising performance. We also coordinate with building managers where communal access and lift times affect deliveries.
We start with a site visit, levels check and a practical method statement covering access, protection and spoil management. Then we complete clearance, excavation and foundations, followed by drainage runs and final levelling to agreed falls. Quality checks are built in at each stage, so surfaces drain correctly and structures sit on stable bases. Homeowners choose us for tidy working, dependable scheduling and a 10-year warranty on qualifying groundwork installations.
Working in the City of Westminster means planning around controlled parking, timed deliveries and narrow mews access. In W1, we often encounter layered sub-bases from previous refurbishments and the need to protect stone thresholds and internal finishes. We use compact plant where required, manage spoil in stages, and keep walkways safe and clean. Our approach suits high-value homes near Claridge's Hotel and busy streets without compromising workmanship.

Costs vary with access, depth of dig, spoil volume and drainage complexity. As a guide, light site clearance and minor levelling may start around £800–£2,000. More involved excavation, grading and waste removal commonly falls between £2,500–£7,500. Groundworks including new drainage and foundations for patios, walls or outbuildings are often £6,000–£20,000+, especially where access is restricted in W1.
Most projects take 2–10 working days, depending on the scope. Small courtyard clearance and levelling can be completed in 1–3 days, while drainage and foundation packages typically need 5–10 days. Timescales change with access constraints, skip permits, the amount of spoil to remove, and whether we uncover old footings or services. Weather and drying time for sub-bases can also extend programmes.
Many garden groundworks are permitted development, especially like-for-like patio bases, levelling and drainage improvements. However, rules can change for listed buildings, conservation considerations, major level changes, new access/driveway works, or anything affecting the highway. In the City of Westminster we also factor in skip licences, parking suspensions and working hours. We’ll advise what’s likely required and help you check before work starts.
We provide a 10-year warranty on qualifying groundwork installations, covering workmanship on items such as prepared sub-bases, foundations and installed drainage runs. It’s designed to give confidence that levels, falls and structural bases have been built correctly. The warranty doesn’t cover damage from third-party works, misuse, or extreme events outside reasonable control. We also document what’s been installed so future maintenance is straightforward.
Groundworks can be tailored to the finish you want: Type 1 sub-base for paving, reinforced concrete bases for heavy stone, permeable build-ups for SUDS-friendly surfaces, and French drains or channel drains for water management. We can set levels for porcelain, York stone, resin-bound, turf or planting beds. We’ll recommend the right specification based on soil, access and intended use, then provide a clear build-up and drainage plan.
