Garden drainage is the difference between a garden that recovers after heavy rain and one that stays waterlogged. Standing water damages lawns, weakens paving, and can contribute to damp close to the property. At Clear Stream Drainage Solutions, we diagnose the cause first and recommend a lasting solution rather than a temporary patch. For homeowners across Cornwall and Devon, that means transparent pricing and work carried out by trained local specialists.
Garden drainage problems rarely arrive overnight. They build over seasons as soil compacts, soakaways silt up, ground levels shift and rainfall patterns intensify. Cornwall properties face this more than most. Heavy clay subsoils, granite bedrock close to the surface and high winter water tables all limit how quickly water can disperse. The result is gardens that flood predictably, paving that lifts and damp problems creeping closer to the building.
For homeowners, poor garden drainage damages lawns, kills planting, undermines paving and can contribute to damp at the base of the property. For landlords and property managers, it is a recurring maintenance cost that erodes rental yield. For commercial sites, it disrupts access and creates safety risks around entrances and car parks.
That is why our approach is built around proper diagnosis, the right specification for the ground conditions, and installation that lasts. We do not fit French drains where soakaways are needed, and we do not specify soakaways where the ground will not accept them.
Local Expertise You Can Rely OnGeneric drainage solutions fail in Cornwall more often than they succeed. The reason is simple: standard soakaway calculations assume free-draining soil. Most Cornish gardens are sitting on clay, shillet, granite or a combination of all three. A soakaway installed without a percolation test will silt up, hold water or back up onto the surface within a few seasons.
Clear Stream Drainage Solutions is based in Falmouth and works across Cornwall every day. We know which areas have shallow bedrock, which villages sit on heavy clay and where coastal rainfall patterns push standard systems past capacity. That local knowledge shapes every specification we issue.
Our garden drainage service covers:
When you call, we focus on understanding the site first. We ask where the water collects, how long it sits, what the ground type is and whether there is an existing system that has stopped working.
That allows us to arrive prepared, with the right equipment for the survey and a clear idea of likely solutions.Whether you need a French drain installed along a saturated boundary, a failed soakaway replaced, channel drainage across a patio or full land drainage for a larger plot, you will receive a practical, local service from engineers who understand Cornish ground.
Regular, hygienic maintenance services ensure your septic system continues to run efficiently.

Considered, Properly Specified WorkGarden drainage is easier to commit to when the process is clear and the costs are known up front. Our approach is built around proper survey, transparent specification and work that lasts.
When you contact us, we arrange a site visit at a time that works for you. On site, we assess where water is collecting, identify the ground conditions, check for existing drainage that may have failed, and look at where surface water can realistically be discharged.
For larger sites or unclear ground conditions, we carry out percolation testing to confirm whether soakaways will work. Where existing systems are involved, we run a CCTV drain survey to check what is actually happening below ground.
You receive a written quote with the recommended solution, the specification, the materials and a fixed price. No vague costs and no hidden extras.
Work is carried out by our own engineers, not subcontractors. We arrive with the right equipment for the specified job, protect access routes and surrounding planting, and install drainage to the agreed depth, gradient and discharge point.
Where ground conditions need adjustment on the day, we discuss it with you before continuing rather than pressing on and adding to the cost.
Where the work involves connecting to an existing drainage run, replacing a failed land drain or installing pipework that needs to be inspected before backfilling, we use CCTV to verify the installation is correct.
You see the footage and keep a copy on file. This matters most for landlords and commercial clients who need a documented record of the work.
Before we leave site, we walk the work with you. We confirm what has been installed, where the discharge points are, what to expect during the next heavy rainfall and any maintenance the system will need over time.
The installation is backed by a 5-year guarantee, with full documentation provided in writing.
When you are paying for garden drainage work, you want a company that specifies the right solution, prices it transparently, installs it properly and stands behind the work. Clear Stream Drainage Solutions is built around that standard.

Permanent Garden Drainage SolutionsIf your garden floods, your patio holds water or your soakaway has stopped working, the problem will not fix itself. Clear Stream Drainage Solutions offers a free site survey, fixed-price quotes and a 5-year guarantee on every installation. Garden drainage that works the first time, specified for Cornish ground.
No. Site surveys and quotes are free. You only pay if you go ahead with the recommended work, and the price is fixed before installation begins.
We assess the ground conditions, the source of the water, the discharge options and the site constraints. Where soakaways are being considered, we carry out percolation testing to confirm the ground will accept water at the required rate. The specification is matched to the actual conditions on your site.
A French drain is a perforated pipe in a gravel-filled trench that intercepts and redirects water across a site. A soakaway is a pit or chamber that disperses water into surrounding ground. French drains move water away from a problem area. Soakaways disperse it. Many Cornwall gardens need both.
Not always. Soakaways need ground that can accept water at a measurable rate. Heavy clay, shallow bedrock and high water tables all reduce or stop soakaway performance. We carry out percolation testing before specifying a soakaway, so you do not pay for a system that will not work.
Most domestic installations are completed within 1 to 3 days, depending on the size of the site and the access. Larger projects, listed buildings and sites with restricted access may take longer. We confirm the timeline as part of the fixed-price quote.
Yes. Every garden drainage installation and repair is backed by a 5-year guarantee.
We minimise disruption wherever possible and reinstate the surface as part of the work. For lawns, we lift turf where practical and replace it once the drainage is installed. For mature planting, we agree access routes with you before starting.
Yes. We have experience working on listed buildings and period properties across Cornwall, where excavation, materials and reinstatement need careful handling. Where consent is required, we will flag this before work begins.
