Response within 24 hours
If rainwater lingers on your lawn or pushes towards the house, a French drain can transform how your garden behaves after storms. In W6, we regularly help homeowners near King Street and Brook Green who are tired of muddy paths and waterlogged borders. Our systems collect groundwater in a gravel-filled trench and carry it safely to a suitable outlet. The result is a drier garden and fewer damp-related headaches.
Hammersmith has a mix of Victorian terraces, mansion flats and modern riverside developments, and each brings different drainage challenges. Terraced gardens often have tight side access and older paving levels that send water back towards the property. Mansion blocks can suffer from saturated communal areas and poorly performing soakaways. We tailor french drains Hammersmith area installations to your layout, levels and existing drainage points.
We start with a site survey, level checks and a clear plan for gradient design, outlet connection and any multiple runs needed. Installation includes trench excavation, geotextile membrane lining, perforated pipe placement and a clean gravel fill to prevent silting. We keep disruption low, leave the site tidy, and explain simple maintenance steps to keep flow rates strong. Homeowners choose us for transparent workmanship, robust materials and dependable aftercare.
Working across the London Borough of Hammersmith and Fulham, we plan for restricted access, basement levels and shared boundaries common in W6 streets. Parking and loading can be limited around Shepherd's Bush and near Hammersmith Apollo, so we schedule deliveries and spoil removal carefully. We also consider riverside conditions and high groundwater near Hammersmith Bridge, selecting pipe depth and outlets to suit. Every design is adjusted to your site levels, not guesswork.

Costs vary with length, depth, access and where the outlet can legally connect. As a guide, small runs for a typical terrace garden often start around £1,200–£2,500. Larger installations with multiple runs, deeper excavation, or complex outlet connection can be £3,000–£7,500+. We’ll confirm a range after a site visit and level checks, then provide a clear written breakdown.
Most single-run French drain installations take 1–2 days on site, including excavation, membrane, pipework and gravel fill. Bigger gardens, multiple runs, or difficult access (common with Victorian terraces) can take 3–5 days. Timescales also depend on locating existing services, the depth needed to achieve the correct gradient, and whether we’re reinstating turf, gravel paths or paving afterwards.
In many cases, French drains in gardens are permitted development because they’re below ground and don’t materially alter the building. However, rules can change if you’re in a conservation area, working near a listed building, altering a public footway, or connecting to certain drainage infrastructure. We’ll advise on the safest route, check constraints, and recommend contacting the council or a surveyor if anything looks borderline.
Yes. Our French drain installations come with a 10-year warranty covering workmanship and correct installation of the system components we supply (pipe, membrane, gravel specification and connections). It’s designed to protect you against issues caused by installation faults, such as poor gradients or failed joints. It doesn’t cover damage from third-party works, blocked outlets beyond our control, or lack of basic maintenance, which we’ll explain clearly.
We can tailor the design to your garden and finish preferences. Options include different pipe diameters, rigid or flexible perforated pipe, and gravel grades chosen for flow and stability. We also specify geotextile membrane types to minimise silt ingress, and can design multiple runs feeding a single outlet where needed. For finishes, we can reinstate turf, add decorative gravel strips, or integrate drainage alongside paving edges.
