Garden Drainage in Richmond | Garden Drainage Specialists
Richmond Professional Landscaping is a design and build landscaping company working on garden design, patios, driveways, decking, fencing, lawns, lighting and drainage across Richmond upon Thames. Commercial grounds, rental properties and family homes all come to us when a garden stays wet long after the rain has stopped.
Much of the borough sits on London clay, which holds water near the surface and leaves lawns soft and patios green with algae. Our garden drainage work starts by tracing where water comes from, where it collects and where it may lawfully discharge. Depending on the site, the answer might be perforated pipe laid in clean stone, a linear channel drain along a patio edge or a crate soakaway set at least 5 metres from any building.
We bring 29 years of experience and more than 930 completed projects to every scheme, with a 97% client satisfaction rate. The company is BALI and APL accredited, TrustMark registered and holds RHS Level 3 qualifications, with 2 BALI National Landscape Awards to its name. Lawns and paving disturbed by trenching are reinstated, and every cost appears in an itemised quote.

Garden Drainage Assessment and Planning
Puddles show where water ends up, not where it starts. A proper drainage assessment traces the source first, be it a neighbouring slope, a blocked gully or clay that never drains.
During the visit we check tree roots, foundations, existing pipework and access for machinery. The written plan then covers only the work the garden needs, with nothing added for the sake of it.
Garden Surface Water Drainage Installation
Rain running off a new patio installation or an old path needs catching before it reaches the house walls. We set linear channel drains on concrete beds, laid to a steady fall towards a lawful outlet.
Removable gratings make cleaning simple, and the channel sizes match the area of hard surface feeding them. Good surface water drainage keeps thresholds dry and stops algae building up on paving.
French Drain and Land Drain Installation
Lawns that turn to mud every winter usually need water moved out from below the surface. A French drain does this with a perforated pipe bedded in a stone-filled trench.
We wrap the stone in geotextile so clay silt stays out of the pipe. On heavy clay, our first job is finding an outlet, because a land drain with nowhere to discharge simply fills up.
Garden Soakaway Installation
Where there is no drain to connect to, collected water needs somewhere to go. A garden soakaway stores it underground in plastic crates or rubble and lets it seep away slowly.
Soakaways belong at least 5 metres from any building, so space matters. Richmond Professional Landscaping runs a percolation test first and sizes the crates from how fast the ground drains.
Garden Regrading and Drainage Groundworks
Low spots beside walls and patios collect every downpour and push damp towards the house. Through garden regrading, we reshape the levels so the ground falls gently away from buildings.
Surplus clay comes away by skip or grab lorry, and topsoil goes back where planting or turf will follow. Any new falls tie into existing drains rather than sending water next door.
Garden Drainage System Repairs and Upgrades
Older gardens often have drains that once worked but have since silted up, cracked or been crushed by roots. A camera survey shows which sections have failed before anything is dug up.
Some drainage repairs need only jetting and a new gully, while others need a fresh run of pipe. Our crew reinstates the lawn or paving afterwards so the garden looks as it did.
Why Choose Us for Your Garden Drainage in Richmond?
- Joined-up groundworks: Richmond Professional Landscaping plans drainage alongside levels, sub-bases and finished surfaces, so new channels sit neatly within the patio, lawn or path.
- Site-specific designs: Pipe routes, outlets and soakaway sizes come from the survey and percolation results, not a standard layout.
- Practical choices: Options range from a single channel drain to a full scheme of land drains, crates and regrading.
- Tidy finish: Turf, paving and planting disturbed by the work are reinstated before we leave, with surplus soil removed from site.
Garden Drainage Process in Richmond
Step 1: Site Assessment and Ground Inspection
Richmond Professional Landscaping walk the garden after rain where possible, noting where water collects and how the levels fall. Our survey also records soil type, existing drains and the distance to nearby foundations.
Step 2: Drainage Planning and System Selection
From the survey, we choose the drainage method and plot pipe routes, falls and outlets. You receive a written plan and itemised quote before any digging starts.
Step 3: Excavation and Ground Preparation
We dig the trenches to the agreed depth and check the gradient along every run. Our crew keeps excavated clay separate from topsoil so the good soil goes back on top.
Step 4: Drainage System Installation
We lay the pipe, channels or crates on prepared beds and surround them with clean stone and geotextile. Every connection is tested with running water before backfilling.
Step 5: Backfilling, Surface Reinstatement and Final Inspection
We backfill in layers, compact the ground and relay any turf or paving lifted during the work. A final water test with you on site confirms the system runs as planned.
How Much Does Garden Drainage Cost in Richmond upon Thames?
Most garden drainage work in Richmond lands between £800 and £6,000, with London prices typically 10 to 25% above national figures. A 20 metre French drain, for example, usually comes to £1,200 to £2,800 before any London uplift.
Drainage Measure
| Typical Cost | What Affects the Price |
|---|---|---|
Perforated land drain or French drain | £40 to £90 per metre | Trench depth, volume of aggregate and how much clay needs removing from site. |
Linear channel drain | £800 to £2,000 per installation | Length of run, paving to cut and reinstate, and the outlet connection. |
Garden soakaway | £1,500 to £5,500 | Ground permeability, crate volume and the 5 metre distance from buildings. |
Combined garden drainage scheme | £3,000 to £6,000 or more | Number of drain runs, regrading work and turf or paving reinstatement. |
Narrow side access and clay disposal add to the cost on many Richmond terraces, since spoil often leaves by wheelbarrow and skip. Richmond Professional Landscaping itemises every trench, outlet and reinstatement cost in a written quote after the site visit.

Frequently Asked Questions About Garden Drainage in Richmond
Does Richmond Professional Landscaping combine drainage with new paving or turf?
Yes. Laying drains before a new patio, driveway or lawn costs far less than digging up finished work later. We design the falls, sub-base and drainage together, so the new surface goes down on ground that already drains properly. A combined scheme typically costs £3,000 to £6,000 or more.
What causes garden waterlogging in Richmond?
London clay is the main cause across much of the borough, as it absorbs water slowly and stays saturated through winter. Compacted soil from building work and patios that fall towards the lawn make it worse. Fixes start at around £800 for a single channel drain.
Does every garden suit a soakaway?
No. A soakaway needs ground that absorbs water at a steady rate, and heavy clay often fails a percolation test. In that case a French drain running to an existing drain or watercourse works better, at £40 to £90 per metre.
Is surface water allowed to go into the main sewer?
Only as a last resort. Surface water should go to a soakaway first, then a watercourse, and only then to a surface water or combined sewer. It must never enter a foul-only sewer, and we confirm the outlet during the survey.
How long does garden drainage installation take?
A channel drain usually takes 1 to 2 days, and a simple French drain 2 to 3 days. A soakaway takes 2 to 4 days, while a combined scheme typically runs to 4 to 7 days depending on access and the weather.
How do I know if my garden needs land drains or just aerating?
If puddles clear within a day of heavy rain, hollow-tine aeration and a sand top dressing usually fix the problem without digging. Water that sits for several days points to poor subsoil drainage, which land drains at £40 to £90 per metre will deal with.
