"Found Cyr Septic and Management through Home Advisor. They were the only company I called even willing to come to our house. They came out that night at no additional charge to replace our septic pump. Very impressed with the honest workers and honest price. I would recommend them to anyone in the area and hire them again in a heartbeat!"

"They came out first to find the septic tank and then would have to come back with the pump truck to pump it. After utilizing the camera mechanism to locate the tank, we were advised that pumping wasn't really needed yet. They could easily have led us to believe it needed to be done, but they chose to be honest and save us the added cost. Honesty & integrity, i like that in a service provider!"

"Doug (owner) and Brandon arrived right as scheduled (prior communication to confirm appointment was excellent). After a lot of digging they were able to locate tank/lid. Very professional and polite to deal with. Extremely reasonable pricing, both were incredibly nice to deal with. Would highly recommend McAtee to anyone. Thanks again!!"

"We were very fortunate that they were able to come quickly and replace our nonfunctioning septic pump promptly. They were professional and easy to communicate with. Given the emergency nature of the project, we did not get other bids so we can't say whether the price was reasonable, but they were upfront about the cost and stuck to their original estimate."

"Josh was fantastic to work with. Bill did my previous inspection in 2017 so I knew I had to call again. Josh was VERY thorough with his inspection. Pointed out every item he felt needed mentioning which was extremely helpful! The septic inspection was fantastic as well. Very neat and clean dig locations as well as information and recommendations moving forward. All in all I would highly recommend MCI to anyone anywhere! Extremely pleased with the results!"
