Testing Service 

Certified Septic Inspection & Mandatory State Testing

Stay compliant and avoid heavy fines with our professional Wisconsin state septic testing. We specialize in the mandatory inspections required every 3 years for homeowners in Waukesha County and the Lake Country area.

We believe in "maintenance as needed," not "maintenance by guess." Using a Sludge Judge, we provide a scientific measurement of your tank's levels. Because sludge buildup is a natural process, pumping isn't always the answer. Our precise data ensures you only pay for a pump-out when your system truly requires it—saving you money while keeping your system in peak condition and fully compliant with state regulations.
System Baffle Cleaning 

System Baffle Cleaning

At Certified Septic Professionals, we don't just 'check' your system—we maintain it. Every inspection includes a thorough cleaning of your baffle filter. This simple step prevents solids from clogging your drain field and helps avoid costly backups. We ensure your system is breathing properly before we leave
