If your lawn stays soggy after rain or water runs towards the house, our team can help. We install French drains, soakaways, land drains and channel drains designed for Sevenoaks’ varied plots. Homeowners around Riverhead and near Knole House often call us to tackle persistent pooling and runoff. We also improve gutter drainage so roof water is taken safely away from foundations.
Sevenoaks is known for large detached houses, executive homes and character period properties with mature gardens and long driveways. These settings can hide old, undersized drainage or broken runs that only fail during heavy downpours. We regularly work across TN13, TN14 and TN15, adapting layouts to protect planting, patios and lawns. If you’re in Otford or Dunton Green, we’ll assess levels and outfalls before recommending the right system.
We start with a site survey, then map levels and water flow; where needed, we use CCTV surveys to pinpoint collapsed pipes or blockages. You’ll receive clear options with practical recommendations, not upselling. Our installations are neat, with careful reinstatement and minimal disruption to borders and paving. Local homeowners choose us for straightforward communication, reliable scheduling and workmanship backed by a 10-year warranty.
Ground conditions vary across the Sevenoaks District, from clay-heavy areas that hold water to freer-draining pockets that still suffer from poor falls. Access can be tight on established plots, and we plan spoil removal, deliveries and parking to keep disruption down. We also factor in long driveways and large roof areas common locally, ensuring surface drainage and gutter drainage are properly connected. If an outfall is limited, we design compliant soakaway solutions with safe separation distances.

Costs depend on the cause, access and how much digging is required. As a guide, CCTV surveys typically start from £180–£350. Small surface drainage or channel drain sections often range £600–£1,500. French drains and land drains are commonly £1,500–£4,000, while new soakaways (including excavation and crates) are often £2,500–£6,500. We’ll survey first and provide itemised options.
Many jobs are completed in 1–3 days, such as installing a channel drain run or a short French drain to relieve a wet area. Larger schemes—multiple land drain runs, a new soakaway, or repairs found after a CCTV survey—can take 3–7 days. Timescales depend on ground conditions, depth, reinstatement (turf, gravel, paving) and whether we need to coordinate with existing services or limited access.
Most garden drainage improvements are permitted development and won’t need planning permission, especially like-for-like repairs or adding French drains, land drains and soakaways within your boundary. However, rules can change if you’re altering levels significantly, working near a highway, or the property is listed or in a conservation area. We’ll check practical requirements, advise on any permissions, and ensure discharge is handled responsibly and compliantly.
Yes. Our drainage installations come with a 10-year warranty on workmanship for the systems we install, such as French drains, soakaways, channel drains and connected pipework. The warranty covers defects arising from installation, including failed joints, incorrect falls or poor bedding. It doesn’t cover misuse, third-party damage, or blockages caused by external factors (for example, building debris or root ingress from neighbouring trees).
We tailor the design to your garden layout and water source. Popular options include perforated land drain pipe in clean gravel with geotextile wrap, modular soakaway crates, linear channel drains with galvanised or polymer grates, and discreet catchpits for maintenance access. For surface water, we can combine falls, ACO-style channels and improved gutter drainage connections. We’ll explain pros, costs and maintenance so you can choose confidently.
