John came out today to pump my septic and I must admit I was sceptical because I have had some bad experience with another company so was not sure what to expect. He was great he walked me around educated me on my tank and the process as he inspected and answered all my questions. Once he was done he showed me the tanks again which we as clean as you would expect a septic tank and looked so much better. I could not say enough about the customer service or the service in general. I highly recommend this company.

My son's bedroom started to reek of sewer fumes and after a bit of research, i realized i should have the septic tank checked/pumped out. I called for service on Monday. They were scheduling 2 weeks out as they are so busy, but Tom got back to me and was able to come out the next day. Tom not only pumped and back-washed the system until complete, but he educated me on the septic system i have, reasons for the issues i was seeing (some of which i didn't notice until Tom pointed them out) and what to do in the future. Exceptional service provided. Cossentino has another lifelong customer.

John serviced our septic system back in April. He arrived when he promised and was professional. John knows septics inside and out and was able to explain to me how my system works. John also provided some pointers on how to keep the septic in good condition. John was very responsive with communication as well. Last but not least his prices are reasonable. I don't think you can ask for much more from a business.
We will not hesitate to use Cossentino Septic again the next time we need septic service! Thanks John!

If you're looking for a new septic service company, look no further than Cossentino Septic. They are reliable, courteous, friendly and very reasonably priced. John is a super nice guy who takes the time to explain what needs to be done and they don't over sell like other companies try to do. Give them a call today, you won't be disappointed!

I hired John Cossentino to clean out my septic system. He was very responsive and arrived on time, despite my location being on the boundary of his service area. John went above and beyond by cleaning dirt and grass away from around my septic lids, he inspected my system, and took the time to educate me on the operation of my system and how to keep it healthy. He does honest work, and his rates are primarily dictated by the disposal fees that the State charges him for dumping our waste. I will definitely use John’s services again and have recommended him to family and friends.

We had John out to pump our septic today and we couldn't be happier with the job he did. Professional, thorough, very knowledgeable, friendly, and seems to really care about the customer. This is our first house, and until now, we weren't 100% comfortable with the ins and outs of our system. Thanks to John, I feel like I know almost everything about our system. Gave great advice, answered every question, and took the time to show me everything he was talking about. Would recommend to anyone 100% and will definitely be calling back when we need service again.
