What Our Clients Say

We were absolutely delighted with the work carried out by Andy and his earthworks team in addressing the problems with our septic tank. The matter was quickly and efficiently dealt with, on time and on budget, we hardly knew that he was there. He saved us considerable money suggesting a solution which met with both Environment Agency and Local authority approval, and handled the tricky dealing with the neighbours on whose land the tank was sited extremely diplomatically.  I would definitely recommend him.

From the Blog


September 2017 beings the chillier weather with it but hopefully not to much rain as Earthworks is busier than ever, Andy and the team have just started an installation for a sewage treatment plant for the National Trust in Devon so fingers crossed for some dry days.

October 2017 has so far been a very busy month for installations, Andy and the lads are on the 3rd install of the month in Rattery Devon.  Also a huge congratulations to Will and Max on completing their Emergency First Aid at Work course with the British Red Cross, hopefully they wont need to practise their new skills anytime soon.
