"My house is closing August 2016 and just found out I need new septic system....House under deposit. Do y9u finance nd get paid at closing? You could put a lien on my property. I don't want to lose this sale and the young buyers love the house but can't afford new system."

"The septic tank had not been cleaned for over 10 years. Bill, from Flushaway Septic came within an hour and a half of my phone call. He explained what had to be done after opening up the septic tank and did the job promptly and neatly leaving the area perfectly clean. He charged $275 for a total pump out with lots of solid waste. He explained how to keep the tank clean and suggested a cleaning every 3 years. I highly recommend him to anyone needing this service."
