I had a sewer backup in my basement bathroom and needed emergency service. Clear River responded very quickly and sent over Nick, an expert technician, to immediately resolve the problem within an hour. Nick's work was excellent, he was very knowledgeable, focused and efficient. He found he problem, got the job done fast and was a pleasure to work with through this mess. Thank you Clear River and Nick for your excellent service!

Never thought I would be reviewing a septic system cleaning company. During the quarter century we lived in this house, never had we experienced competency in this field. Clearwater, and their representative, Frank, did a complete & thorough service knowledgeably without rushing & without wasting time. He completed his work with certainty and efficiently. We felt that after the Clearwater,Frank, experience, that we had wasted money all these years. He used electronic equipment to locate system & recorded the locations for future use. Oh yeah, the fee was quite fair, which is unusual these days. An incredible company ! Thank you Clearwater, Frank Dr. Norman G. Bartner

This is a shout out to Nestor & Ricardo. Nestor showed up with a smile, took a look at both cesspools & told me things I wasn't aware of. Ricardo popped the covers & both investigated the condition of the pools. Both were friendly & respectful. Nestor explained my options going forward with regard to pool maintenance, type of pool and condition. Thanks to Nestor & Ricardo for getting it done.

Josh came to my home to assess my septic tank and clogged drain/plumbing. He was professional, courteous, explained everything he was going to do and why. He tried to maintain the integrity of my home all while unclogging my poop pipes! He even tried to save me some money by using the shower drain first with the snake, but then finally had to remove the toilet and go that route. He was very calm, reassuring and let friendly. At a time when a customer is distressed he offered reassurance and a level of confidence that I needed in a service. When your toilets don’t work and are backed up with an entire family, it’s a bit stressful. I would recommend Josh and Clear River to anyone!!

I recently used ClearRiver Environmental to service the cesspools at my home in Sayville and couldn't be happier with the experience. From the initial phone call to the completion of the work, their team was professional, knowledgeable, and easy to work with. They arrived on time, explained everything clearly, completed the service efficiently, and left the area clean when they were finished. It's refreshing to work with a company that takes pride in both their workmanship and customer service. If you're looking for a reliable cesspool service company on Long Island, I highly recommend ClearRiver Environmental. Honest, professional, and dependable service from start to finish. I will definitely be using them again in the future.

I want to thank Frank for coming by on short notice yesterday Sunday. We also called at 3:30 so I know it was very late but he wasn’t bothered by coming out to us. I didn’t realize this company was so far we’re in Huntington. Frank really helped us out he was very thorough and very knowledgeable. Thank you The Roldan’s

We had a swamp gas smell in our house. Clear River's people arrived pretty much immediately and worked for 6 hours to diagnose and resolve the issue. Jake and Josh were competent, driven, and personable. Not only did they rapidly resolve an issue that posed a threat to my baby's health, but they did so in a way that reminds me of what service used to be in this country. If you have a plumbing issue, you can't go wrong with these guys.

Wenfred, Terrelle and Alex were professional, and courteous. they explained everything clearly, were careful not to damage sprinkler lines and completed my septic tank service efficiently with no surprises. Their workmanship and customer service, including every person I spoke to at the office, exceeded our expectations. I highly recommend Clear Water Environmental to anyone looking for dependable septic services.
