Septic Inspection in Lewisville

Septic inspection for homes on a private septic system (SSTS). We camera-scope the sewer line from the house toward the tank, looking for roots, sags, cracks and separated joints, and we coordinate the licensed SSTS compliance inspection through our licensed partner, so it is one booking and one schedule for you. Many Minnesota counties require a compliance inspection when a home with a septic system is sold.

Lewisville is a small Watonwan County farm town of older homes south of Madelia. Housing here runs to early-1900s farm-town homes, across the compact town core.

Septic systems in Watonwan County

Watonwan County's website states on-site septic systems are subject to inspection at transfer of property, when living space with a bedroom or bathroom is added, and at discovery of failure. Sellers file a Property Transfer Septic System Disclosure/Agreement Form with the County Recorder at the time of recording. We camera-scope the sewer line from the house and coordinate the licensed SSTS compliance inspection as one booking.

Questions

Common questions.

What does your septic inspection include?
Two parts. We run a camera through the building sewer from inside the house toward the tank and record its condition: roots, cracks, sags, separated joints and blockages. We also coordinate the licensed SSTS compliance inspection of the tank and soil treatment area, so the whole septic picture is booked and scheduled together.
Is a septic inspection required when a house sells in Minnesota?
It depends on the county. Many Minnesota counties require a compliance inspection at the time of sale; others require one only in shoreland areas or leave it to the lender. Ask the county's environmental services office early, because a failing system can change the terms of a sale.
Can I book the septic inspection with the home inspection?
Yes. Book it as an add-on and we schedule the line scope and the compliance inspection around your home inspection, so the results land inside your inspection window.
What are signs of septic trouble?
Slow drains throughout the house, gurgling, sewage odors indoors or in the yard, wet or unusually green spots over the drainfield, and backups in the lowest fixtures. Any of these calls for a scope and a full evaluation before closing.
Does Watonwan County inspect septic systems at sale?
Yes. The county says systems are subject to inspection at transfer of property. Sellers complete the county's Property Transfer Septic System Disclosure/Agreement Form and present it to the County Recorder with the transfer documents. The form requires supporting paperwork such as a certificate or inspection report. We scope the sewer line and coordinate the licensed inspector as one booking.
Do you cover Lewisville?
Yes — Lewisville is within our Mankato base's direct ring, thermal imaging and mold testing included. The older farm-town stock gets wiring, plumbing, chimneys and foundations dated precisely, and flat prairie clay keeps grading and basement moisture in every report. Watonwan County is Radon Zone 1.
