If rainwater lingers on your lawn or pools by the patio, it’s usually a drainage design issue rather than “bad weather”. We install French drains, land drains, channel drains and surface drainage to move water away from buildings and usable garden areas. Homeowners around Thornton Heath station and Broad Green often call us after repeated waterlogging through winter. We can also carry out CCTV surveys to pinpoint hidden blockages or collapsed runs before any digging starts.
Thornton Heath has a mix of Victorian terraces, Edwardian semis and 1930s houses, many with compact rear gardens and shared access. These layouts need careful routing of pipework, discreet gullies and sensible outfalls that won’t upset neighbours. We regularly work in CR7 and nearby Selhurst and South Norwood, adapting drainage to tight side returns and older garden levels. Where downpipes discharge poorly, we upgrade gutter drainage so water is captured and carried away properly.
We start with a site visit to assess falls, soil type and where the water is coming from, then recommend the most effective solution—often a combination of surface drainage and a soakaway. Installations are kept tidy with clear protection of planting, paving and boundaries, and we explain how to maintain the system. You’ll get transparent options, photos of the work, and practical aftercare advice. Our local reputation is built on doing it once, doing it right, and leaving your garden usable again.
As drainage contractors in London Borough of Croydon, we’re used to the mix of older terraces and 1930s homes with altered garden levels and extensions. Access can be narrow, so we plan materials, spoil removal and parking to minimise disruption on residential streets. Around Grangewood Park and the wider CR7 area, we often find compact gardens where smart falls and slimline channel drains make a big difference. We also consider safe discharge points and keep work aligned with local expectations and good practice.

Costs depend on the cause and the amount of excavation. As a guide, CCTV surveys often start from around £150–£350. A small channel drain or local surface drainage fix may be £500–£1,500. French drains and land drains typically range from £1,500–£4,500 depending on length and reinstatement. New soakaways are commonly £1,800–£5,000+ based on size, depth and access in CR7.
Many targeted repairs, such as adding a short channel drain or improving a downpipe connection, can be completed in a day. French drains and land drains usually take 2–4 days depending on length, digging conditions and how much paving or turf needs lifting and reinstating. Soakaways can take 1–3 days, but may take longer if access is restricted or if we need to reroute existing services.
Most garden drainage improvements are classed as permitted development and don’t require planning permission, especially when you’re improving how water is managed on your own land. However, rules can change if you’re altering levels significantly, working near boundaries, or connecting to public sewers. We’ll advise on the best compliant approach, check practical constraints, and recommend when it’s sensible to speak with Croydon Council or a drainage authority before work begins.
Yes. Our drainage installations come with a 10-year warranty on workmanship for the systems we install, such as French drains, land drains, channel drains and soakaways. It covers defects caused by installation issues, including incorrect falls, poor connections or avoidable failures of the installed runs. The warranty doesn’t cover blockages caused by misuse, tree root ingress from unmanaged planting, or damage from third-party works, but we’ll always help diagnose issues quickly.
We offer several options depending on the problem and the look you want. Popular choices include gravel-filled French drains, perforated land drain pipe in geotextile, polypropylene channel drains with galvanised or black grates, and modular soakaway crates wrapped in membrane. For gutter drainage, we can connect downpipes to new underground runs or improve existing gullies. We’ll recommend the right design after assessing falls, soil conditions and available space.
