Our drainage services in Dorking cover the town and the Mole Valley villages around it, from homes off the High Street to houses at the end of long country lanes. Monster Drainage unblocks drains, jets pipes clear of grease and silt, and surveys drains with CCTV cameras across RH4 and RH5, for homeowners, landlords and businesses. Our engineers are available 24/7 for drains that will not wait.
Dorking town, greensand and two rivers
Dorking’s High Street runs along an outcrop of Lower Greensand, a sandy rock that drains far better than clay. The River Mole passes the eastern side of the town on its way through the gap it has cut in the North Downs, and the Pipp Brook flows through to join it at Pixham. Close to the brook and the river, gullies and soakaways have more water to cope with after a long spell of rain. On the greensand itself, rainwater soakaways tend to work well, which is not always true on clay.
Out to Westcott, Brockham and Newdigate
Beyond the town, Westcott lies to the west, Brockham to the east beside the Mole, and Newdigate further south. Village properties often have longer drain runs, older pipes and fewer access points than a town house. We cover these villages as well as Dorking itself, and the approach is the same everywhere: find the blockage, clear it, and explain what caused it. If your home is down a private track, a note of the best way in helps us find you.
Drain jetting in Dorking for repeat blockages
Drain jetting is often the right tool for Dorking drains that block more than once. A hose fed into the pipe sprays water at high pressure, forward to break up the blockage and backward to scrub the pipe wall. It shifts compacted silt, kitchen fat and the fine roots that creep into old joints, leaving the pipe clean along its length. On a longer rural run, high pressure jetting from a chamber can clear a stretch of pipe that rods would struggle to reach.
Camera surveys for older drains
Where a drain keeps blocking, or before you buy or extend an older property, a CCTV drain survey shows what is inside the pipe. Cracks, roots, displaced joints and sagging sections all show up clearly, so any decision rests on evidence rather than guesswork. We explain the findings, support them with footage where needed, and the documentation is available for your property records or an insurance enquiry. For a house you are buying, the report can sit with the rest of your paperwork for your surveyor or solicitor.
Homes on the Box Hill side
North east of the town, the chalk slopes of Box Hill rise above the river. Homes on this side of Dorking can sit well above or below the lane, with steep gardens and long drives, so the drain may travel some distance before it reaches the sewer. Knowing where your chambers are makes any visit quicker, and a survey can map a run you have never seen.
What we do across RH4 and RH5
Whether you live in the town or out in the villages, we can help with:
- Blocked drains inside and outside
- Blocked toilets that will not clear
- Emergency call outs at any hour
- Drain jetting for grease, silt and roots
- CCTV surveys for buyers and repeat faults
- Commercial drainage for local businesses
We are a family run business. We give clear quotes with no hidden charges, and we always explain what we found. Whatever the problem, the first step is a conversation about what you are seeing.
Older village cottages
Many of the older cottages around Dorking were built long before mains drainage, and their pipes have been added to or altered over the years. Runs can change direction, join in unexpected places or pass beneath an extension. When we clear a drain like this, we take care to trace where it goes, and a camera survey can record the route for the future.
Landlords with tenants in RH4
Letting a house in or around Dorking? Book the visit yourself and we will contact your tenant to arrange access. Once the drain is clear, we let you know what we found and whether anything should be planned for later, so you are not caught out by the same problem next year.
Shops, pubs and offices in town
Businesses along the High Street and West Street rely on toilets and kitchen drains that work all day. We clear blockages, jet kitchen drains that gather grease, and can arrange scheduled maintenance for premises where the same drain keeps causing trouble.

Dorking and village drainage questions
Q: My house is a long way from the road. Can you still reach the drains?
A: Distance from the road matters less than access to the drain. We work from the inspection chambers along the run, so it helps if you can tell us where the covers are, how far they are from somewhere to park, and whether any are hidden under gravel or planting.
Q: When is jetting better than rodding?
A: Jetting is the better choice when a pipe is lined with grease or silt, or when roots have begun to grow through the joints. Rodding is often enough for a single soft blockage, such as paper or wipes.
Q: Can I call you out of hours?
A: Yes. Our engineers are available 24/7, so you can call at night or at the weekend if water is backing up.
Q: Which areas around Dorking do you cover?
A: Dorking, Westcott, Brockham and Newdigate, and the wider Mole Valley including Leatherhead. Our areas page lists the other towns we serve.
