"My septic alarm went off last week on one of those 10 degree nights , so I called Matt at A & M septic next day. Matt sent out a knowledgeable and professional crew the next day (bitter cold again) to diagnose and fix the issue. They were done in a couple hours, and my septic is working great. Matt was easy to deal with, professional, and prompt to respond. His crew explained the issues to me and quoted me a price before they started. I highly recommend A & M for your septic system repairs. Thank you Matt and Crew!"

"We needed a complete septic replacement because the house we bought was not up to code. Matt and his team did an excellent job. I would have given 5 across the board except the project was delayed 8 weeks and we were not kept informed."

FAQs for septic system repair projects in Wentzville, MO

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
