Blocked drains, CCTV surveys, pump stations and septic tanks looked after for homes and businesses in Yateley and the Blackwater valley.
Yateley is a large, mainly residential town on the edge of the Blackwater valley, with Yateley Common on one side and the river and its old gravel pits on the other. Most homes are on mains drainage, and much of our work here is clearing blocked drains and surveying pipes that keep giving trouble.
A lot of Yateley was built from the 1960s onwards, so many drains are now well into middle age. Pitch fibre and early plastic pipes can deform, and clay pipes crack and let roots in. A CCTV survey shows what’s happening underground before you start digging.
Towards Eversley and the more rural lanes, there are homes on septic tanks, cesspits and treatment plants, which we empty and service too. Our crews are in Hampshire most days and we’re available 24 hours a day.
We clear blocked toilets, sinks and outside drains with high-pressure jetting, and we’ll tell you what caused the blockage so you can stop it happening again. For shared drains, we’ll help you work out who’s responsible.

If a drain keeps blocking, smells, or you’re buying a house, a CCTV survey shows the condition of the pipes. We can spot deformed pitch fibre pipes, cracks, root ingress and displaced joints, and give you a written report with photos.

Some homes and small developments around Yateley rely on a pump station to lift sewage up to the sewer. We service them, test the pumps and alarms, clean the chamber, and come out 24/7 if one stops working.

Out towards Eversley and the rural lanes, we empty septic tanks and cesspits and service treatment plants. We’ll check the tank while we’re there and tell you if anything needs attention.

What we see most often in the town’s drains.
Some homes built in the 1960s and 1970s have pitch fibre drains, which can soften and deform over time. A camera survey will show if yours are affected.
Close to the Blackwater and the old gravel pits, the water table can be high. That can affect soakaways and drainage fields in winter.
A CCTV survey before you buy can save you an expensive surprise. It’s a small cost compared with a drain repair.

Questions answered
What homeowners in and around Yateley ask us most.
Pitch fibre was used for drains in some homes built in the 1960s and 1970s. Over time it can soften, blister and go oval, which causes blockages. A CCTV survey will show whether you have it and what condition it’s in.
It’s worth considering, especially for an older property or one with large trees nearby. A survey costs far less than a drain repair and gives you something to negotiate with if problems turn up.
Drains serving more than one property are usually the water company’s responsibility. Drains serving only your home and inside your boundary are usually yours. We can locate the problem and tell you which it is.
Yes. Homes towards Eversley and the rural lanes often have septic tanks, cesspits or treatment plants, and we empty and service them all.
