Hiring a septic contractor in Columbia
Septic (onsite wastewater) contractors handle everything from routine septic tank pumping and cleaning to repairs, inspections, and new system installation. States license each role separately (a pumper is not necessarily licensed to install, and vice versa), so match the license class to the job.
Before you sign anything: confirm the license number on this page is still active with Missouri, ask for proof of insurance, and get at least three written quotes; pricing on this work varies widely by site conditions.
