Drain Unblocking in RH5: Rural Drainage Around Dorking, Done Properly
RH5 isn't town drainage. It runs out across the Surrey Hills around Dorking: the Holmwoods, Coldharbour, Wotton, Abinger, Mickleham, Beare Green, Capel and Ockley, where homes are spread out, often off the mains, and the ground decides how a drain fails. We're usually with you within the hour, the price is agreed before any work starts, and there's no standard call-out fee.

Why RH5 Drains Fail the Way They Do
The most useful thing to know about drainage in RH5 is the ground. North of Dorking it's chalk, the Leith Hill ridge is greensand, and south towards the Holmwoods, Capel and Ockley it's Weald clay, which holds water for weeks once the autumn rain arrives. That wet-then-dry swing works the joints of older clay pipe looser season after season.
By the time a Holmwood property is fifty-odd years old, almost every joint on a long clay run has some movement in it. A fine root from the heavy tree cover finds the gap, wipes and kitchen fat snag on the root, and the drain backs up, usually between November and February, when the ground is fullest.
Rod it and the water moves for a few weeks, then it's back, because the joint and the root are still there. On a repeat blocker we find the fault rather than keep clearing the same length of pipe. Since the 2011 private sewer transfer, a shared run beyond your boundary is usually the water company's, so we trace the fault and tell you whose it is before anyone mentions digging.
Septic Tanks, Cesspools and Soakaways
Much of RH5 sits in the Surrey Hills National Landscape (the old AONB), where homes are scattered and plenty never connected to a mains sewer. They run to a septic tank, cesspool or package treatment plant along a long buried pipe, and a "blocked drain" on one of those is a different job from a blocked mains lateral.
We jet the runs, find where a long rural pipe has dipped, rooted or collapsed, and tell you honestly whether the tank just needs emptying or the run needs repair. Those long runs are exactly where faults hide, so we find the fault before anyone quotes for digging. Not sure how your system works? Our explainer on how a soakaway works is a good start.
What We Do, and When
Most RH5 jobs come down to three things, mains or off-mains.
High-Pressure Jetting
For the clear itself: set fat, silt washed down off the wooded slopes, or a root mat. The jetter strips the pipe wall clean along its full length, with no chemicals going into ground that drains to the River Mole.
JettingRepairs & No-Dig Relining
Usually a patch or liner cured inside the existing pipe, so the lane, verge or garden stays untouched. It matters on tired clay and ageing pitch fibre runs.
Drain repairsPlanned Cleaning
For the property that floods the same gully every autumn: a scheduled visit beats another 6pm emergency.
Drain cleaningHow to Tell Which You Need
Do you need a quick clear, or is the pipe the real problem? Here's how we judge it.
| Sign | Likely just needs unblocking | Likely needs repair |
|---|---|---|
| How often it blocks | First time, or once in years | Every few weeks or months |
| What we find | Fat, wipes, silt or leaves in the run | A rooted, cracked or dipped joint |
| After clearing | Flows freely and stays clear | Clears, then backs up again soon after |
| The fix | Jetting restores full flow | A no-dig patch or liner at the defect |
If it's the right-hand column, clearing it again and again just delays the bill. We'll show you what has failed and price the repair so you can decide with the facts in front of you.
Emergency Cover Across RH5
A toilet rising over the rim, or a gully overflowing across a yard at the end of a Holmwood lane, won't wait for morning. On an off-mains property it can mean waste heading back towards a tank that's already full.
- Rods, a kinetic ram and a jetter on every van, so most blockages are gone on the first visit
- We leave the area clean and safe before we go
- If what we find is a repair rather than a one-off, we say so
- A fixed price agreed first, no standard call-out fee, and any out-of-hours charge agreed before we attend

RH5 Drainage: Common Questions
Is there a call-out fee in RH5?
There's no standard call-out fee. The engineer agrees one fixed price with you before starting, and that's what you pay, with nothing added at the end.
How quickly can you reach the Holmwoods or Capel?
We're on call around the clock and usually with you within the hour, even out in the villages. Call with your address and we'll give you an arrival time.
Do you work on septic tanks and soakaways?
Yes. Much of RH5 is off-mains, so it's routine. We jet and check the runs to tanks, cesspools and soakaways and tell you whether it needs an empty, a clear or a repair.
Why does my rural drain only block in winter?
The clay ground south of Dorking holds water from autumn onwards, which works the joints of old clay pipe and lets roots in. Most repeat blockages here peak between November and February for that reason.
Do you come out at night and weekends in RH5?
Yes. We answer 24/7 every day of the year, bank holidays included, and the person who answers can send an engineer.
My drive is gravel. Will you have to dig it up?
Usually not. Most repairs we do are a patch or liner set inside the existing pipe, so the drive, lane or garden stays as it is.

Ash came to unblock the drain with an hour's notice. He was super friendly, knowledgeable and cleaned up after himself.
Fantastic company. Farhad came to unblock our drains in Croydon. He arrived on time, was very polite and explained everything really well, then carried out a drain unblocking inspection to make sure everything was cleared.
Fahad was amazing. I had a blocked external drain and he was super helpful getting it resolved. Could not have done more to help, and charged a very reasonable price.
Absolutely brilliant company. They came out the same day and resolved the issue within a few hours. Very reasonably priced too. Highly recommend the team!
Brilliant service! I left a message on Good Friday at 2:30pm and by 5pm everything was sorted. Saved my Easter. Highly recommend.
They came within the hour to unblock my outside sewage manhole. Very respectful, knowledgeable and efficient. Reasonably priced. Would definitely use again.
