Blocked drains, CCTV surveys, grease traps, gullies and pump stations looked after for homes, businesses and managed sites across Aldershot.
Aldershot grew up around the army, and the town still has a mix of Victorian terraces, post-war estates, newer housing on former military land and busy commercial streets. It’s on mains drainage, so the work we do here is mostly about keeping drains flowing: clearing blockages, surveying problem pipes, emptying grease traps and looking after pump stations.
Older drains in the town centre are often clay, and decades of tree roots and ground movement take their toll. Newer developments, on the other hand, often rely on a private pump station to lift sewage into the main sewer, and those need regular servicing to keep working. We see both every week across the Blackwater valley.
Our accreditations, including SafeContractor and Achilles UVDB, mean we can work on managed and contractor-vetted sites. Our crews are in Hampshire most days, and we answer the phone 24 hours a day, 365 days a year.
We clear blocked drains in homes, shops and flats with high-pressure jetting. If the same drain keeps blocking, we survey it with a camera so you can see the cause, whether that’s roots, a cracked pipe or a displaced joint, and get a written report for your landlord, insurer or managing agent.

Aldershot has a lot of takeaways, cafés and restaurants, and every one of them produces fat, oil and grease. We empty grease traps on a regular schedule, early or late if you’d rather we weren’t there during service, and leave a waste transfer note each time.

Many newer homes in and around Aldershot depend on a pump station run by a management company. When a pump wears out or a float sticks, the alarm goes off and the chamber fills. We service pump stations, test the pumps, floats and alarms, clean the wet well, and come out day or night when one fails.

Car parks, yards and industrial units need their gullies and interceptors cleaned to stop flooding and keep oil and silt out of the drains. Our jet/vac tankers clean and empty them, and we can set up a regular schedule for your site.

Old and new drains side by side, and a lot of shared systems.
Victorian and early 20th-century drains are often clay with mortar joints. Roots find their way in, so repeated blockages are worth a CCTV survey.
Homes built on former military land may drain to a pump station that isn’t looked after by the water company. Check your management pack to see who is responsible.
In converted houses and blocks of flats, a blockage in a shared drain affects everyone. We can tell you where the problem is so the right person deals with it.

★★★★★So glad we found them. The team was professional, courteous and helpful. They came the next day and pricing is way more competitive than a national chain. Will be using them again in a year's time to service the pump. Thanks again!

Questions answered
The questions homeowners, landlords and businesses in Aldershot ask us most.
Usually you are responsible for the drain that serves only your property, inside your boundary. Shared sewers and those outside your boundary are normally the water company’s. If you’re not sure, we can find the blockage and tell you whose pipe it’s in.
It depends. Some have been adopted by the water company; many on newer estates are still run by a management company or developer. Your management pack or service charge statement should say. We service pump stations for management companies across the area.
It depends on its size and how busy you are. A busy takeaway might need it every few weeks; a small café much less often. We’ll suggest a schedule and adjust it as we see how quickly it fills.
Yes. After a CCTV survey you get a written report with photos showing the condition of the drain and any defects, which you can pass on.
Yes. We’re SafeContractor, Achilles UVDB and RISQS approved, and our engineers hold confined space entry certificates for work in chambers and wet wells.
Yes. We answer the phone 24 hours a day and have crews in Hampshire most days. Call 03333 233566 and we’ll tell you when we can be there.
