Knox Sewer & Septic is truly a family owned business. No sub contractors. We found this company through word of mouth. We worked with Jim (owner), brothers Jeff & Darrell & son Ethan. Honest, good people, which is hard to find these days. When we called Jim Knox, he was there the next day to check out our failed septic system. Our system needed a perimeter drain & Presby sand mound septic system due to our saturated water table. We now have a new septic system working efficiently & no water standing in our back yard. They did a great job, very trustworthy. Jim & his crew work with the customer & answers any questions you might have. Thank you for your expertise & we learned a lot. We would recommend Knox Sewer & Septic A +. They go the extra mile.

It went better than I expected. The entire crew were very nice and worked very efficiently. This company has their act together. They had all the equipment and all seemed very professional. Jim Knox seems to be a very honest man and explained everything he was going to do and how long it would take. He kept in contact with me pretty much every day from when we signed the contract to the completion date. He and his crew worked long days on my project to get it done ahead of what he scheduled.

Jim knows his "stuff" and was very easy to work with from start to finish! We had another company out prior to Knox and they did about $1,200 worth of work to try and fix the high levels in our septic tank only for it to fail less than two weeks later. We then called Knox and wished that we would have done that from the beginning. Jim diagnosed our septic tank failure in less than 15 minutes by probing all around our yard. He was very up front and honest with us about timelines/costs and he and his team replaced our entire system in less than a week with no surprises along the way! Jim was always available for any questions that popped up before the big dig and his communication throughout was outstanding. We just had our final walkthrough yesterday and my husband and I both have a good understanding of how our new system works, what needs to be done to maintain it, and we also know that if any issues or concerns arise, Knox will be right there to help us through them! Highly recommend this company! Added Bonus: My 5 year old son LOVES construction vehicles and Jim and his crew were so kind and friendly towards him during every encounter. It made getting our entire yard dug up a little bit easier! Thanks guys!

We are selling our home. After a suspicious dye test on the septic system, septic inspections were scheduled. Company owner came to property somewhere around 4pm. Boyfriend/homeowner and buyer were also in attendance. I was inside in the room adjacent to septic access. I heard company owner say total septic system failure and it would cost 15k - 25k to replace. Boyfriend came inside and proceeded to tell me the company owner stuck a probe into the ground one time, pulled the probe out, then stated total septic system failure and it would cost 15k - 25k to replace. He determined this after the largest 2 day rainfall we have had this year with a septic tank that was full and scheduled to be pumped and without doing an actual inspection. The following day a different company came, probed the ground repeatedly marking the entire drainfield as well as the distribution box location, and viewing the hole where the septic access had been unearthed. Their report came back with no deficiencies and not suggesting any repairs. This was also before the tank had been pumped.
Response from Knox Septic Sewer Service
"I was called by the perspective buyers on this property. They had hired an inspector to do an evaluation of said properties septic. The inspector had dug up access to septic tank and the hole to the tank area, he told his clients that he was unable to view the tanks condition due to the hole had filled with sewage water. I was called as an installer to figure out why. Unfortunately, septic systems ideally should work and perform during wet and dry weather seasons. This particular tank and trenches was found by me to be way overfull upon arrival. I probed to locate the drain field to see if It was dry, clean, saturated or bio-mat sludgy. If it's dry and clean then a possible minor repair can sometimes be the fix, but this system was extremely way over saturated. When we probed, and pulled the probe out of the ground on top of the trenches, the sewage water came up out of the probe hole. I totally was aware of the weather conditions as I am a certified inspector and certified installer. Again, I gave the buyers and gentleman that seemed to be owner that was home both of them verbal findings of the condition of that system that day. Septics don't always work and or perform their best in wet seasons, but I always do honest best for all involved. As for the 1st inspector and the 2nd inspector that was hired by owners likely, you might check 2 things: A- Are they certified installers and years of experience B- are they certified inspectors. I am both and completely stand by ALL words spoken by me as an installer that day. Owner, Jim Knox 3172816412"

Hiring septic pumping is the pinnacle of adulthood. Knox communicated an issue with the truck the day I was scheduled and promptly showed up when the issue was fixed. The tech was very nice and didn't leave 'effluent' in my yard. One of the best prices I could find at $250/1K gal w/ Angie's List. Will hire again when the time comes.

Knox Septic's negligence nearly resulted in the death of my three-year-old son this weekend. Prior to the purchase of my home, I had the septic system thoroughly inspected and was present during the inspection. The lid was old, but was securely locked, and the septic needed to be pumped. The prior homeowner hired Knox to do the job. Knox left the septic riser completely unsecured, despite the obvious presence of young children in the area. They provided a receipt (I cannot attach a photo to this review, but have posted it to other sites) which failed to disclose the problem, nor did they make any attempt to report the obvious hazard to the building department. This issue was only discovered when my three-year-old managed to kick the cover off while playing soccer with a friend. The opening was certainly wide enough for a small child to fall in, but thankfully I was close by and quickly pulled the boys away before anyone was injured or killed. When confronted with how this job was left, Mr. Knox claimed that IF Knox left the riser lid unsecured (they apparently do this often enough that he didn't remember this instance) they verbally told someone. THIS IS NOT GOOD ENOUGH, particularly when it was clear small children were nearby. In addition to their blatant incompetence and clear disregard for safety, Mr. Knox was incredibly rude when I dared to suggest he had been negligent in not alerting the building department or writing the hazard on the receipt. He spoke over me the entire time I was talking, and then had the audacity to tell me I had an "attitude" for telling him "Sir, I am still speaking. Let me finish" in response to his repeated interruptions. I said this because he repeatedly interrupted me as I described how the presence of numerous children's toys in the area would have led any reasonable person to know how dangerous an unsecured riser is. He told me because of my "attitude" he would do nothing to fix the problem (I was going to be charged, of course). It's unreal to me that anyone would behave this poorly. I plan to take formal action with the state license board. I have never spoken with someone with such callous disregard for the welfare of children or lack of remorse for the severity of his lapse in judgment.
Response from Knox Septic Sewer Service
"I have let this review stand for a few weeks now with no response. During that time, I have spoken several times with my brother, which he is the one that operates our service truck and takes all initial calls. There is 1 hidden factor that the current homeowner did not know perhaps and or did not relay in her review, and that is that when my brother pumped this particular tank more than 7 months ago, the owner at the time was told that the lid did not lock. The owner at the times response was " the new owners can deal with it ". Unfortunately, we have no legal authority to call the local health department or building inspectors about a lid that does not lock. She is definitely correct and completely valid in her concerns for the safety of all, as we are. It almost seems a little vindictive to s*** this on other social media sites though, just saying. As for the phone conversations, my brother felt that he was being attacked and talked down to. Those that interact with him know his personality. Please feel free to call me directly with any questions 3172816412 Jim"

Response from Knox Septic Sewer Service
"Mrs. [Member Name Removed], I do apologize for not calling you directly. But, your husband kindly requested that we leave during our last visit 4-6 weeks ago. As you know, I was at your property 4 years ago, when I visited at least 3 or 4 times with soil scientist and local Health Department in attempt to design a septic replacement due to your then failing septic. You personally, were always very kind, your husband, not so much. Not that he was rude, but he was very expressing that he was not going to be told what to do on his own land, as a homeowner, I get that. He actually accused me of being there as working for the government and being against him, although he asked me to be there as a septic designer. Therefore, when I was asked to come back 4-6 weeks, I did. After meeting with your husband to explain the process of septic replacement and possible costs associated, he expressed his feelings that he was not going to be told by anyone, that he was going to have to spend his money on a new septic system. So, I left again. I have had other contractors call me about this site because of my known involvement. Mrs. [Member Name Removed], I personally have been to your property minimally 5 or 6 times, and I usually give a business card each time, you or your husband have my cell number, I can only be asked to leave, so many times, before I refuse to return. I wish you luck on your replacement, please feel assured, your local health department is there to inspect and make sure who you choose as a contractor, that they do the install correctly. Jim"

It went great, the company was responsive, on time, professional, and did a great job at a reasonable cost. They pumped just shy of 1,000 gallons and it took about 15 minutes. I would recommend them.

We had an emergency with our septic system. They were right out the next day and explained very clearly what the plan was. Ultimately, we had a dosing tank pump that needed to be replaced. They were prompt and professional.

Perfect. The holes were already dug and tank was accessible. This was right after many heavy rains so I was worried about excess water. They let me know what to expect and potential risks they might encounter. No risks were realized and they were efficient for a good price.
