I’ve used other companies in the past, but none have matched the level of service SewerTech Li provided. Their team came for septic pumping and even did a quick inspection to make sure everything else was running properly. Top-notch experience!

We had a major septic backup on a Sunday night and didn’t know who to call. SewerTech Li responded right away and had someone at our house within the hour. They were fast, professional, and explained everything clearly.

Our drains were slow for weeks, and no one could figure out why. SewerTech Li came in with camera inspection tools, found the issue, and fixed it the same day. Super professional and respectful of our home.
