How to Hire a Septic Company
Short answer: Confirm the company is licensed or registered with your state or local regulator, get at least two quotes, ask what's included, and get the scope and price in writing before work starts.
Check credentials first
Most states require septic installers, pumpers or inspectors to be licensed, registered or certified with a state or local agency; requirements and the exact title vary by state. See our septic regulations by state guide, and ask the company directly for their license or registration number, then verify it with your state or local regulator rather than taking their word for it.
If you need a point-of-sale inspection in a state that regulates who can perform one, like Massachusetts's MassDEP-approved System Inspectors, confirm the specific person is on the approved list, not just that the company is generally reputable.
What to ask for in a quote
Ask exactly what's included: the pump-out itself, disposal fees, a visual inspection of the tank and lids, and whether they'll check the effluent filter if your system has one. Ask what happens if they find a problem while they're there, and whether an estimate for repairs is included or extra.
Get the price and scope in writing before the truck shows up, and ask how they dispose of the pumped material; they should be using a permitted disposal site.
Red flags
Be cautious of a quote that's dramatically below others in your area, a company that won't provide a license or registration number, or anyone who pushes chemical additives as a substitute for pumping. The EPA does not recommend most septic tank additives; a well-maintained system doesn't need them.
