If your garden holds water after rain, the problem is usually poor falls, compacted ground, or blocked outlets. We install French drains, channel drains, and land drains to move water away from lawns, patios, and foundations. Working across SE3, we’re often called out near Blackheath Common and Blackheath Village where heavy downpours can quickly overwhelm older drainage routes. Our solutions are discreet, effective, and built to cope with London weather.
Blackheath’s Georgian townhouses, Victorian villas, and period conversions often have mature gardens, raised patios, and historic boundaries that need careful handling. We plan routes that avoid roots, protect paving, and keep paths usable during works. For homes in Greenwich, Lee, Lewisham and Kidbrooke, we tailor drainage to plot shape, access, and existing services. The aim is simple: stop surface water and protect the fabric of the property.
We start with a site visit and, where needed, CCTV surveys to locate breaks, silted runs, or hidden soakaways. You’ll receive a clear recommendation covering grading, catch pits, and the right discharge method, with options for pump systems if gravity drainage isn’t possible. Our team works cleanly and reinstates surfaces properly, keeping disruption low. Homeowners choose us for straightforward advice, reliable scheduling, and workmanship backed by a 10-year warranty.
Across Blackheath, ground levels and older garden layouts can leave limited fall to the street, so we often combine grading with soakaways or pumped discharge. Access can be tight on period streets, so we plan materials and spoil removal to minimise parking and disruption. We also consider tree roots and heritage-style paving common around The Paragon and nearby roads. Where council guidance affects discharge points, we advise early and keep the design compliant.

Costs vary with access, depth, and whether you need new outfalls. As a guide, small fixes such as a short channel drain and catch pit often start around £600–£1,200. French drains and land drains for a typical rear garden are commonly £1,500–£4,000. Larger schemes with soakaways, re-grading, and reinstatement can be £4,000–£10,000+, especially if a pump system is required.
Most straightforward installations take 1–3 days, such as a French drain run or a channel drain along a patio edge. Medium projects involving a soakaway, multiple catch pits, and careful reinstatement typically take 3–7 days. Timescales depend on ground conditions, depth of excavation, access through the property, and whether we’re tying into existing drainage. CCTV surveys and clear plans help keep the programme predictable.
Most garden drainage improvements are classed as permitted development and don’t need planning permission, particularly when you’re adding drains, soakaways, or re-grading within your boundary. However, rules can change if you’re altering a public connection, working near protected trees, or affecting a listed building or conservation area. We’ll flag any likely constraints during the survey and advise if you should check with the Royal Borough of Greenwich or Lewisham.
We provide a 10-year warranty on our garden drainage workmanship, covering installation defects such as poor falls, failed joints, or incorrect bedding that causes blockages or settlement. The warranty applies when the system is used as designed and not damaged by later building works or unapproved alterations. We also explain maintenance steps—like keeping grates clear and checking catch pits—so performance stays consistent through the seasons.
We design to suit your garden layout and finish. Popular options include French drains with clean gravel margins, discreet slot or grated channel drains for patios and driveways, and soakaways using modular crates or traditional rubble pits where appropriate. Catch pits and rodding points can be positioned for easy maintenance, and land drains can be wrapped to reduce silt. If gravity isn’t viable, we can specify a pump system with alarms and non-return valves.
