Your Septic System's Best Friend.

A-1 Septic has been family-owned and operated, proudly serving Colorado since 1976.

Prevent Problems Before They Overflow

For homeowners and commercial property owners alike, prioritizing septic tank maintenance is essential. Over time, scum and sludge can accumulate in your tank, and without regular inspections and pumping, this buildup may lead to overflow or complete failure. A failing septic system can have serious consequences, including hazardous drainage issues that threaten both your property’s value and safety.

Regular preventative care and maintenance are the most effective ways to protect your investment and save money in the long run.

Join the families and business owners across Weld, Adams, Broomfield and Boulder counties that trust our team at A-1 Septic to pump the sludge.

  • Great service going above and beyond to point out potential future issues that saved me thousands in repairs. Highly recommend this family owned business!

    Brian in Platteville, CO

  • I needed my Septic tank pumped desperately on a Saturday. A1 showed up on Sunday. He determined my issues were inside the house after a complete inspection and would not accept money for a service call. He said I’m good for about 1 year. Friendly, professional and prompt.

  • We’ve recently had severe septic issues and Spenser has gone out of his way to get to us quickly to pump our tank on last minute notice. We’ve rounded the corner with a new system so hopefully no more emergencies. I really appreciate what Spencer and Venessa have done for us since taking over ownership of A-1. Previous ownership was amazing as well. It’s been a seamless transition in my opinion. A-1 Septic is in good hands.

  • A big thanks to the entire A-1 team for a job well done. It's apparent that consumer service a top priority from the initial appointment be scheduled to the clean up and departure. I particularly appreciated the honest observation Spenser shared with us reviewing our system without a hidden agenda to make additional sales. No question I will be working with A-1 for years to come.
