"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."

"Troy and Cyr septic did a great job. I found Troy to be honest, straight forward and willing to get right in there and get the job done. I was most impressed that Troy was willing to drop everything he was doing when I contacted him on Sunday. He showed up, assessed the situation and created a plan of action and quote. All the prep work was done on Monday, then we had to wait for a pumping service which took a few days. Troy was back that afternoon after the tank was pumped to finish the job. In the end Troy collected exactly what he quoted for the job and my tank was repaired"

"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."

"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!"

Septic Tanks questions, answered by experts

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

You only need to pump the septic tank. The leach field allows the liquid and waste to naturally seep into the ground, so there’s no need to pump the leach field. You should call a local septic tank pumping service to remove the materials from the tank every three to five years. Without pumping the septic tank occasionally, solids could flow into the leach field pipes and clog them.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.
