Standing water after rain can quickly spoil a courtyard or planted border in W1. Our team installs robust drainage solutions around Berkeley Square and Mount Street, protecting paving, lawns and basement-adjacent gardens. We pinpoint why water is pooling—compacted subsoil, poor falls, blocked outlets or failed soakaways—then put the right system in place. The result is cleaner surfaces, healthier planting and fewer damp-related issues.
Mayfair properties often combine heritage detailing with modern landscaping, from Georgian mansions to palatial townhouses and luxury apartments with terraces. These gardens frequently have limited soil depth, high-value stone finishes and sensitive boundaries that demand careful workmanship. We plan drainage routes to minimise disruption and preserve existing features. If you’re near Hyde Park or bordering Marylebone, we’ll also account for varied ground build-ups and historic alterations.
We start with a site assessment and, where needed, CCTV surveys to confirm blockages, broken pipes or poor connections. Next, we propose a clear design: grading for correct falls, land drains or channel drains for surface water, and soakaways or catch pits for collection and dispersal. Installations are completed neatly with protection to floors, walls and planting, followed by testing and tidy reinstatement. Homeowners choose us for transparent reporting, reliable scheduling and a 10-year workmanship warranty.
Working in the City of Westminster means planning for controlled parking, narrow access points and strict noise and waste handling expectations. Mayfair gardens can sit over mixed sub-bases from previous refurbishments, so we verify levels and permeability before specifying soakaways or pumps. Where gravity falls are limited, we design compact pump systems with service access. We also keep finishes and reinstatement standards high to suit W1 properties.

Costs vary with access, depth, and the type of system required. As a guide, small drainage improvements (localised channel drain or minor regrading) often start from £900–£2,000. French drains and land drains for a typical courtyard or small garden are commonly £2,500–£6,500. Larger schemes with soakaways, catch pits, or pump systems can range from £6,500–£15,000+ depending on excavation complexity and reinstatement.
Most Mayfair drainage jobs take 1–3 days for a targeted fix, such as adding a channel drain, catch pit, or short French drain run. A full garden scheme with grading, multiple drain runs and a soakaway is typically 3–7 working days. Timescales depend on access restrictions, the amount of excavation, whether we’re working around mature planting or premium stone, and if CCTV surveys reveal hidden defects to address.
In many cases, garden drainage works are permitted and don’t require planning permission, especially when you’re improving drainage within your property boundary. However, rules can change for listed buildings, conservation considerations, works near party walls, or if you’re connecting to existing drains. We check the practical requirements, advise on any permissions, and ensure the design manages surface water responsibly without causing issues for neighbouring properties.
Yes. We provide a 10-year workmanship warranty on our garden drainage installations, covering defects arising from installation quality. This includes correctly fitted drainage runs, connections, and reinstatement related to our work. Components such as pumps may also carry manufacturer warranties, which we register and explain at handover. We’ll also provide maintenance guidance—like clearing channel grates and periodic checks—to keep the system performing as intended.
We tailor the design to your garden layout and finishes. Popular options include French drains with clean stone backfill, land drains for lawn areas, discreet linear channel drains with galvanised or stainless grates, and catch pits for easy maintenance. For poor falls, we can specify compact pump systems with alarms. We’ll advise on pipe sizes, geotextiles, soakaway crates, and grading so the solution suits your soil conditions and aesthetics.
