As a neighbour, You can expect to be woken up at 7 or 7:30, as that is when construction starts, it is almost impossible to sleep during that time and construction only finishes at 3-4 PM, they also may or may not leave a water pump on 24/7. If you are considering hiring them, please reconsider. In one year, all they have done is make one large hole and put in a pump that is on all day and night. So please, consider another company
