Why call EcoBuild for your sump pump

24 hours a day

A pump that fails during heavy rain will not wait until morning. We answer nights, weekends and bank holidays and treat rising water as an emergency.

Fixed first time

We carry common parts such as floats and non-return valves, so many pump faults are sorted on the first visit.

Clear pricing

You know what it will cost before we start. The invoice matches what you agreed to.

Repair or replace, honestly

If a repair is worthwhile we do it. If the pump has had its day, we tell you and explain the options.

Clean and tidy

Dirty water cleared up, floors protected, and the old pump taken away when we leave.

Sump pump repairs we carry out

Most sump pump failures come down to a jammed impeller, a stuck float or a faulty valve. We find which one and fix it, rather than replacing a pump that only needs a small repair.

Pumps that will not start

A pump that stays silent while the water rises. It may be jammed by debris, have a failed motor, or not be getting a signal from its float. We find the cause and tell you whether it is worth repairing.

  • Seized and jammed pumps freed
  • Power and connections checked
  • Motors tested

Pumps that run but do not clear the water

The pump hums but the water level does not drop. Usually a blocked impeller or strainer, a blocked discharge pipe, or a non-return valve that has failed or stuck shut.

  • Blocked impellers and strainers cleared
  • Discharge pipework checked
  • Non-return valves replaced

Floats, valves and alarms

A float that sticks or tangles can leave a pump never starting, or running dry. We free, adjust or replace float switches and check the valves so the pump starts and stops when it should.

  • Float switches freed or replaced
  • Non-return valves checked
  • High-water alarms

We also repair

  • Twin pump systems and standby pumps
  • Pumps that switch on and off repeatedly
  • Noisy or vibrating pumps
  • Leaks on the discharge pipework
  • Smelly or silted-up sumps and chambers
  • Damaged lids and access covers
  • Pumps that run dry or overheat
  • Basement drainage and pump chambers

Basement flooding right now?

Keep safe around electrics. Do not wade through standing water if sockets, extension leads or equipment are in it or near it. Switch off the electricity at the consumer unit only if you can reach it without going through the water.

Move what you can. Lift belongings off the floor and, if it is safe, stop any burst pipe by turning off the stopcock, usually under the kitchen sink.

Then call us on 079 1616 8585. We are available 24 hours a day across London.

What affects the price

We look at the problem, tell you what it needs and what it will cost, and only then start work.

What we look atWhy it changes the cost
Repair or replaceA stuck float or a blocked impeller is a quick repair. A pump with a failed motor, or one close to the end of its life, is usually better replaced.
Single or twin pumpsA twin pump system with a standby takes longer to work on, and gives you protection if one pump fails.
Size and type of pumpPumps are chosen for the volume of water and the height they must lift it, which affects the cost of a replacement.
Access and depthA shallow pit under a cover is easy to reach. A deep chamber needs more time, lifting equipment and care.
Discharge pipeworkThe length and route of the pipe taking water away, and any valves on it, change how much work is involved.
