"Blake Excavation was recommended and we are ever so grateful! Our Septic Drainfield had failed after 42 years and we were in need of urgent help. Despite delays courtesy of an understaffed DEQ Jason kept us informed and was onsite the minute the permit was approved. The crew showed up on Friday and worked through the weekend to get us back online. They were courteous and caring and we are ever so grateful!"
