If your lawn stays boggy after rain or water pools by patios, a properly designed French drain can transform how your garden performs. In Chiswick, we’re often called to solve runoff issues near Chiswick High Road and properties close to the river. Our system captures excess water in a gravel-filled trench and channels it away through a perforated pipe. The result is firmer ground, fewer puddles and reduced risk of damp around external walls.
Chiswick’s Georgian houses, Victorian villas and Edwardian family homes frequently have mature gardens, older paving and mixed ground levels that can trap water. We’re experienced with side returns, narrow access and sensitive boundaries where neighbouring gardens sit at different heights. Whether you’re near W4 or bordering Gunnersbury and Kew, we tailor the drainage layout to your plot. That includes choosing the right depth and fall so water flows consistently, even in smaller courtyards.
Our approach starts with a site survey to identify the source of water and the best discharge point. We carry out trench excavation, install a geotextile membrane, add graded gravel, lay perforated pipework, then connect to a suitable outlet with a designed gradient. Multiple runs can be added for wider lawns or long side passages, and we reinstate surfaces neatly. Homeowners choose Fine Landscaping for clear communication, tidy working practices and a 10-year warranty on our installation.
Chiswick gardens often combine clay-heavy patches with compacted ground from older landscaping, which can slow drainage. We plan excavations around established planting and manage access where parking and loading can be limited near busy roads. For french drains in London Borough of Hounslow, we also consider practical outlet options, from soakaways to lawful connections where appropriate. Our method suits period properties while keeping disruption to a minimum.

Most domestic french drains chiswick area installations take 1–3 days, depending on run length and surface reinstatement. A simple trench along a lawn edge can often be completed in a day, while multiple runs or deeper excavations may take longer. Timescales are affected by access for machinery, disposal of spoil, the need to work around roots or services, and whether we’re reconnecting paving, turf or gravel afterwards.
In many cases, French drains are classed as garden drainage works and don’t require planning permission. However, rules can change if you’re altering levels significantly, working near a boundary, or if your property is listed or in a conservation area. Discharging water into public drains also has restrictions and should be done correctly. We’ll advise on the likely requirements and, where needed, help you check with the council before work starts.
Yes. We provide a 10-year warranty on our French drain installation workmanship, covering correct assembly of the system: trench build-up, membrane, gravel, pipe placement, gradient design and connections. The warranty is designed to give peace of mind that the drain will perform as intended when used and maintained properly. It doesn’t cover damage from third-party works, severe ground movement, or blocked outlets caused by neglect, but we provide clear maintenance guidance.
We can tailor the design to your garden and the problem area. Options include different pipe diameters, clean-out points for easier maintenance, and single or multiple runs to intercept water from lawns, patios or side passages. Gravel grade is chosen to balance flow and stability, and we always use a geotextile membrane to reduce silting. Where needed, we can add a discreet channel to an outlet or soakaway and explain the pros and cons on-site.
