Highly recommended 👌Posted on Jason PontieriTrustindex verifies that the original source of the review is Google. Clear River was phenomenal. Sewer was backing up, we called Clear River, they had someone on site right away to assess the issue. James was their field representative, very professional, and knowledgeable. He completed the septic system maintenance, backfilled the area and left everything neat and clean. Would highly recommend this company.Posted on Nancy BroderTrustindex verifies that the original source of the review is Google. Clear River just replaced my cesspool and over flow. They did an amazing job! Highly recommend!!Posted on rommel kongTrustindex verifies that the original source of the review is Google. I had an excellent experience with Clear River Environmental Service. This was my first time getting my septic system cleaned since purchasing my home, and I wasn’t sure what to expect. Their technician, Jake, was awesome from start to finish. He was professional, friendly, and incredibly knowledgeable. Jake took the time to answer all my questions and explain how my septic system works in a way that was easy to understand. As a first-time homeowner with a septic, that meant a lot. The service was efficient, thorough, and left me feeling confident about how to properly maintain everything moving forward. Highly recommend Clear River Environmental Service—and especially Jake—for anyone looking for reliable, honest, and top-quality septic service.Posted on Hector ReyesTrustindex verifies that the original source of the review is Google. To say that I am happy with the service provided by Clear River Environmental and the work performed by Jason would be an understatement. i’ve had a historically rocky relationship with plumbers in the past, so it always gives me a bit of anxiety when I have to call one, but from the first conversation with the young lady that called me till the completion of the job this company was professional, communicative, and a pleasure to work with. When there was a slight hiccup, Rob came back out the next day to ensure everything was working properly. That piece of mind is something that is priceless to know that a company stands behind their work Thank you to clear river environmental for the amazing jobPosted on denise raioTrustindex verifies that the original source of the review is Google.

Jake was excellent and answered all my questions regarding the cesspool pumping and chemical application.Posted on Doug WohlTrustindex verifies that the original source of the review is Google.

Called to let me know driver was on his way which was earlier than expected. James showed up and was very professional and answered all my questions. Had more work done than I expected but it was needed and done right. Very happy with the work done. Thanks James! Thanks, Clear River Environmental.
