Customer Reviews

“If you have septic tank related problems this is the company that you want to contact. Henry, Ed and the rest of the crew are consummate professionals and know their business inside and out. Although my problem was relatively simple in the big scheme of things, I still received a complete and efficient job completion. From the very competitive job estimate, to completion of the job, I can honestly, and gladly state, that there were absolutely no issues. Whether it be for a new septic system, or repairs to an existing septic system, I highly, and without reservation, recommend Big Bore Drilling & Hydro Flushing. No need to look elsewhere!!!!” ~Jim W.
