Septic System Repairs
in Fond du Lac, WI


A malfunctioning septic system doesn’t always mean you need a total replacement; often, the issue lies within specific mechanical or structural components. At Laudolff Septic Services, we specialize in diagnosing and fixing the vital parts that keep your system moving. This includes pump repairs and replacements for pressurized systems, as well as float repair or replacement to ensure your alarms and cycles are functioning accurately. We also handle clearing blocked lines between the house and the tank, installing riser extensions to bring buried lids to the surface for easier access, and—when necessary—full tank replacements if an old unit has become structurally unsound.
Pumps are essential for proper wastewater flow and require immediate attention if they fail.
Tree roots, debris, or shifting soil can cause blockages that prevent your system from draining correctly.
Cracks or leaks in your septic tank can lead to costly water contamination issues.
Properly functioning floats ensure your tank doesn’t overflow.
Easy access to your tank is essential for maintenance and inspections.
The extension on the manhole must be either a maximum of 6″ below grade or a minimum of 4″ above grade, according to SPS 383. A riser below grade will require digging before servicing. Riser extensions, on the other hand, allow for easy access to the tank and electrical components. Laudolff Septic Services can also replace covers for the manholes.
Septic problems can’t always wait.
That’s why we offer a dedicated emergency repair line for urgent issues, available 24/7.
