Customers say: Quality work

"The contractor completed the work on time. The estimate was $4000 but I was billed $5500 with the explanation that they had to add a P-Trap. Excessive. They had to dig through a brick walkway to replace the pipe. Rather than removing the brick then digging, they just dug through the brick. Then when filling in the trench, they buried all the brick in the trench and left a large mound of dirt on the patio (photo, after 45 minutes of me removing dirt). They also buried the old pipe in the trench (Photo) which I had to dig up and remove so i could replace the bricks. Finally, they did not measure and placed the vent right in the middle of where the sidewalk was. After contacting the owner/contractor, they reduced the bill by $1000."

FAQs for septic system repair projects in Saint-Louis, 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.
