If your garden is holding water after rain, the issue is usually poor fall, compacted ground or blocked outlets. Our team works across SE21, including routes near West Dulwich station and Belair Park, to restore proper drainage without unnecessary disruption. We design and install surface drainage, channel drains and land drains to move water away from patios, lawns and foundations. Where the cause isn’t obvious, we start with a CCTV survey to pinpoint failures quickly.
West Dulwich has plenty of Victorian villas, Edwardian houses and period conversions, often with mature planting and older drainage runs. These properties can suffer from overwhelmed gullies, tired gutter drainage, or lawns that never fully dry out. We tailor solutions for side returns, narrow access paths and shared boundaries, common around Dulwich Village and Herne Hill. The aim is simple: protect the building fabric and make the garden usable again.
We begin with a site visit to assess levels, runoff routes and existing connections, then recommend the most cost-effective fix. Installations are carried out neatly, with clear communication on excavation areas, spoil removal and reinstatement. You’ll get a written scope, transparent options, and workmanship backed by our 10-year warranty. Homeowners choose us because we solve the cause of waterlogging, not just the symptoms.
As drainage contractors in London Borough of Lambeth, we’re used to period properties, mature trees and tight access that affect drainage design. Around Dulwich Wood and Thurlow Park, roots and leaf fall can contribute to blocked gullies and overwhelmed surface runs. We plan deliveries and waste removal with local parking constraints in mind, and we set falls carefully so water moves to the right outfall. Every system is designed to suit your plot, not a generic template.

Costs vary with access, depth, and how much excavation and reinstatement is needed. As a guide, small surface drainage or channel drain sections often start around £450–£1,200. French drains commonly fall in the £1,200–£3,500 range depending on length and materials. Soakaways are typically £1,800–£5,000+, especially if crate systems and deeper digs are required. CCTV surveys are usually £180–£450.
Many jobs are completed in 1–3 days, such as installing a short channel drain run or a small French drain. Larger schemes—multiple land drains, a new soakaway, or significant patio lifting—often take 3–7 working days. Timescales depend on ground conditions, the depth required, access for machinery, and whether we’re reinstating paving or turf. We’ll confirm a realistic schedule after the site assessment.
Most garden drainage improvements are permitted development, especially where you’re managing water on your own land using soakaways, French drains or surface channels. However, rules can change if you’re altering levels substantially, working near boundaries, connecting to public sewers, or if the property is listed or in a conservation area. We’ll advise on the likely requirements and can help you check Lambeth guidance before work starts.
Yes. Our drainage installations come with a 10-year workmanship warranty, covering defects related to how the system is installed (for example, incorrect falls, poor connections, or installation failures). We also use reputable branded components where possible, which may carry their own manufacturer warranties. The warranty doesn’t cover damage from third-party works, severe ground movement, or misuse, but we’ll always explain care and maintenance clearly.
We offer several proven options depending on the problem: French drains with clean gravel and geotextile wrap, land drains with perforated pipework, and soakaways using traditional rubble or modern crate systems. For hardstanding, we install channel drains with plastic or galvanised grates, plus discreet gullies and silt traps. We’ll recommend the best layout after checking levels, soil type, and where the water can safely discharge.
