Full Spectrum Plumbing did a professional job investigating and repairing our septic system. They looked it over on Tuesday and gave me an estimate/quote to dig out the first section of the line coming from the septic tank to the first distribution box. They suspected tree roots were the problem. I moved a greenhouse out of the way and called to schedule them to return on Thursday. They were here at 7:30am ready to go. They dug out the old pipe and found it mangled by roots. They explained to me what needed to be done, I agreed, and they were done at 10:15am. I highly recommend this company.
