"Iâ ve read the reviews on this company and everyone has rated them 5 stars. I donâ t understand this. We are nearly a month in trying to get septic plans and I still donâ t have them. They tell me a date. The next week I call, of course no one ever answer the phone, I get and email saying itâ s going to be longer. Soil test was already completed we talking plans only. In the time Iâ ve been waiting for the plans, Iâ ve already paid for so I can obtain a permit through Jackson County, the house could have had the slab poured and the entire house framed. No joke. I could be running electrical now but instead Iâ m still waiting for them to draw plans so I can get a permit Good luck. Maybe donâ t pay them upfront."

"Damion couldn’t have been more helpful. He truly seemed invested in not only addressing the problem, but understanding why it happened and what we can do to prevent future occurrences. It was refreshing to see a contractor care about a real fix as opposed to patching together the easiest solution."

"They didn't show up for 2 appointments over the last 2 years. No call to let me know they were late. I waited 6 hours before a call on one visit. Prices are higher than anyone else. They cancelled my service agreement at my request but still after 2 months have not refunded my money that they promised. Sending emails every 2-3 weeks still no response. Save your money and your time."

FAQs for septic system installation and replacement projects in Kansas City, MO

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
