"Marcus came over the day after I requested the quotes (quotes requested Sunday, he came Monday.) He assessed the situation and explained options and pricing. He very willingly attempted the lower cost option first, even though we had doubts it would work. He told if it did not work and we had to go to the higher cost option, I would only be charged for that, not both. We did have to go to that option and he was able to clear the clog from my sewer line. He then inspected with a camera and showed me that there were several roots intruding on the line. He recommended repeating the process with a nozzle designed to remove these. He did not have that on his truck, so another visit was scheduled for today with a different tech. This was also successful and it was clear from the camera inspection at the end that the roots were gone. I was expected a horrible mess from this process, and was very happy that both operations were completed with minimal additional sludge in my basement."

"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!"

"Came when they said they would. Did the job efficiently and thoroughly, explained the probable cause and how to avoid it. Quote was half the amount the other service I contacted quoted as thier base fee ($170 vs $345) and that is what they charged."

"The owner of the company arrived as scheduled and was very professional and a really nice man to deal with. He assured me he would find the location of the access to our septic tank no matter what it may take. He.found it within 15 minutes and it was hidden under rip rap. When he came back to pump it out, he did an excellent job and replaced the rip rap. You wouldn't even know he had been here. I would recommend McAtee highly."

"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!"

Septic Tanks questions, answered by experts

Most deep wells can be expected to last somewhere between 30 and 50 years. This assumes that the well and all of its components are properly maintained on a regular basis. During this time, it is unlikely that modern deep wells will run dry over the course of their typical lifespan. That is one of the biggest benefits of digging a deeper well. 

The price you’ll pay for service from a septic tank company will depend on the specific service you need. Here are some common services, along with average pricing:

  • Anaerobic septic system installation: $3,000–$8,000

  • Aerobic septic system installation: $10,000–$20,000

  • Septic tank pumping: $250–$550

  • Percolation test: $700–$2,000

  • Leach field installation: $2,000–$10,000

These numbers vary based on your septic system size, property layout, and more, so the best way to get an accurate estimate is to contact a septic tank professional for a custom quote.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

Costs depend on tank accessibility, size, and local rates. Regular service serves as preventive care, averting costly emergency repairs or system replacements.
