I am not someone who would typically take the time to review a company but in this case I felt it was warranted. Spoke to Keith @ company and within 24 hours Hydraulic Hammer was on job site. Within 48 hours they were taking out ledge. Operator was great and he tapped a couple other spots on the lot when cellar hole was done. They had me check septic tank area dig trench to septic to make sure there was no ledge. They left the hammer on the job site for a couple days after in case we ran into something else which of course we did. They offered to take care of small remaining ledge upon pick up. They were great overall and reasonable on the price. I would highly recommend them. Peter
