From our office in Smallfield, a couple of miles away, we clear blocked drains in Horley and around Gatwick.
Horley is a town on mains drainage, built up quickly in the last century and surrounded by countryside that is not. Our office is in Smallfield, a couple of miles east, so a blocked drain in Horley is on our doorstep, and our crews are in and around the town most days.
The whole area sits on Weald clay, which is heavy and slow to drain. Soil like that moves as it dries out and swells again, and moving ground can open the joints in a drain. Combine that with the tree roots that follow moisture, and you can see why drains on clay tend to need attention sooner or later.
Around the airport there are hotels, car parks and businesses with their own drains, gullies and grease traps. We clear those as well as home drains, and for the farms and cottages in Charlwood, Outwood and Burstow, where the pipework may lead to a tank, we can deal with that end too. Ring and tell us what is happening and we will find where the blockage is.
What’s included
We locate the blockage, clear it and tell you what we found.
Lifting the covers shows where the flow stops, and so whether the fault is in your pipe or past your boundary.
High-pressure jetting shifts fat, silt, scale and paper, and leaves the pipe wall clean.
Roots that have grown into a joint can be cut out and the pipe descaled.
If a drain keeps blocking, our Horley CCTV drain surveys show why.
We can clear gullies and empty grease traps for hotels, car parks and kitchens.
Beyond the town we also empty septic tanks and cesspits, so one team covers both.
Many of Horley’s drains run through clay that shifts with the seasons. A blockage that comes back after a dry summer or a wet winter often points to a joint that has moved, and a camera can show whether that is the case.
We clear the pipe with jetting first, so the cause can be seen. For businesses near the airport, we can clear the drain and see to the grease trap on the same visit.
About drain unblocking
Round Charlwood, Outwood, Burstow and Horne, plenty of homes have no mains sewer. A drain that runs slowly could be a blockage in the pipe, a tank that has filled, or a drainage field on clay that is waterlogged.
We can clear the pipework, empty the tank and take a look at how the system is working. The Horley page explains what we do for tanks and treatment plants.

Questions answered
Pipes serving only your property, inside your boundary, are normally yours. Shared drains and the pipe outside the boundary have been the water company’s since October 2011. We find where the blockage sits first, so you know who should pay.
The ground around Horley is Weald clay, which moves as it dries and swells. That can shift pipe joints, and roots follow the moisture into them. Paper, fat and wipes then catch on the roots or the displaced joint.
Usually. A high-pressure hose goes in through a chamber or gully and the water breaks up the blockage and washes it down the pipe.
It might be, but it can also mean the tank needs emptying or the drainage field is waterlogged. If every drain in the house is slow, or the garden is wet, it is worth checking the tank as well as the pipe.
Yes, together with gullies and grease traps. Tell us about access and busy periods and we will plan around them.
A camera can. Once the pipe is clean we film it, and the footage shows roots, cracked or displaced pipe, or scale. Our Horley CCTV page explains what the survey involves.
Stop using the drain and keep chemicals out of it, since they make the job harder and unpleasant to work around. If sewage is coming into the house, phone us.
