Downham’s established residential estate includes 1920s cottage homes, 1930s semis and post-war housing, often with compact side access and shared boundaries. These property styles can suffer from tired soakaways, silted land drains and poorly directed downpipes. We’re used to working around existing paving, sheds and extensions while keeping disruption low. For properties across BR1, we tailor drainage layouts to suit plot size and fall.
We start with a site visit to map levels, identify runoff routes and check where water is entering or pooling. Where needed, we carry out CCTV surveys to confirm blockages or collapsed pipework before any digging begins. You’ll receive a straightforward plan, itemised options and a schedule that fits around your household. Our workmanship is backed by a 10-year warranty, which is why homeowners choose our drainage contractors Downham area year after year.
Across the London Borough of Lewisham, we regularly see heavy, compacted ground and gardens altered by past landscaping, which can slow infiltration. Downham plots can be narrow, so we plan pipe runs and soakaway locations to suit access and boundary constraints. We also factor in parking and delivery access near community facilities such as Downham Health and Leisure Centre. Our drainage contractors in London Borough of Lewisham work to practical, compliant solutions without overbuilding.

Costs vary with access, depth, and how much pipework is needed. As a guide, minor surface drainage or channel drain sections often start around £350–£900. French drains commonly fall in the £1,200–£3,500 range depending on length and reinstatement. New soakaways are typically £1,500–£4,500, especially if excavation and spoil removal are significant. CCTV surveys are usually £180–£450.
Most small drainage fixes take 1 day, such as adding a short channel drain or correcting a downpipe connection. French drains and land drains are commonly 1–3 days depending on length, depth and reinstatement of turf or paving. A soakaway installation often takes 1–2 days, longer if access is tight or ground is difficult to excavate. Weather, hidden services and disposal requirements can also affect timings.
Most garden drainage works, including French drains, land drains and replacing like-for-like drainage runs, are usually permitted development. However, rules can change if you’re altering levels significantly, working near a public highway, or connecting into certain surface water systems. If your property has restrictions or you’re in a sensitive area, extra checks may be needed. We’ll advise on the safest compliant approach before work starts.
We provide a 10-year workmanship warranty on our drainage installations, covering defects caused by installation errors such as incorrect falls, poor jointing or inadequate bedding. It also includes remedial labour to correct covered issues. The warranty doesn’t cover damage from third-party works, misuse, or extreme events beyond normal design assumptions. We’ll explain what’s included for your specific system and provide aftercare guidance to keep it performing well.
We install a range of options including perforated land drain pipe with clean gravel, geotextile-wrapped French drains, modular soakaway crates, and polymer or galvanised channel drains with various grates. For gutter drainage, we can re-route downpipes, add leaf guards, or connect to new soakaways where suitable. We’ll choose pipe diameters, gradients and outlet points based on levels, soil behaviour and expected runoff. You’ll get choices that balance performance, appearance and budget.
