93 licensed septic contractors based in Calvert County. Every license number below is sourced from official Maryland records, with a link to verify it yourself.
Grouped by the county of the address on each business's state license record, which can be a mailing address; it doesn't tell you where the business works. Where the record doesn't name the county of the address, its ZIP code decides (a ZIP that crosses a county line goes to the county holding most of its homes), then its town.

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 Maryland, ask for proof of insurance, and get at least three written quotes; pricing on this work varies widely by site conditions.
