Water pooling in a courtyard or along a basement lightwell can quickly damage paving, planting and brickwork. We install high-performance French drains around Mayfair homes, with routes planned to suit tight boundaries and premium finishes. Whether you’re near Berkeley Square or along Mount Street, we keep disruption low and drainage performance high. Our systems move water away from problem areas and into a suitable outlet connection.
Mayfair’s Georgian mansions, palatial townhouses and luxury apartments often have mature landscaping, raised planters and complex hardscapes. These features can trap surface water, especially where falls are minimal or paving has settled. We’re used to working around heritage details, stone setts and high-value planting schemes. If you’re close to W1 or bordering Hyde Park, we’ll tailor the layout to your plot and access constraints.
Every installation starts with a site survey and a clear gradient design, then precise trench excavation to the right depth and line. We fit perforated pipe, wrap with a geotextile membrane, and backfill with clean gravel for long-term flow. Where needed, we create multiple runs to catch water from several zones and connect to a compliant outlet. You’ll receive straightforward maintenance guidance and a written 10-year warranty for peace of mind.
Mayfair sites often have limited access, strict building management rules and controlled parking, so we plan deliveries and spoil removal carefully. In the City of Westminster, we also consider nearby utilities and basement structures common in W1 properties. Our french drains in City of Westminster are designed to work with tight falls and high-end finishes, with tidy protection for stonework and planting. We’ll advise on the best outlet option based on your plot and local constraints.

Costs in Mayfair vary with access, depth, number of runs and where the outlet can connect. As a guide, small problem areas may start around £1,200–£2,500, while longer runs across patios or multiple collection lines are often £3,000–£7,500+. Complex sites with restricted access, premium reinstatement or additional soakaway/outlet work can be higher. We provide a detailed, itemised quotation after a survey.
Most installations take 1–3 days, depending on trench length, ground conditions and reinstatement requirements. A short run beside a lawn can be completed in a day, while a courtyard with stone paving, multiple runs and careful spoil handling may take several days. Timescales are affected by access in W1, the depth needed to achieve the correct fall, and the complexity of the outlet connection.
French drain work in gardens is usually permitted development, as it’s typically below ground and doesn’t alter the building’s external appearance. However, rules can change for listed buildings, conservation considerations, basement works, or if you’re altering a public-facing area. We check constraints specific to the City of Westminster, confirm where water can legally discharge, and advise if any permissions or management approvals are required before work starts.
