What affects the price

The final bill for septic work depends on a few specific variables. First, the size of your tank and the total volume of waste removal play a role. We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them. The distance from our truck to the tank also impacts the setup time. Every property has unique plumbing needs, and exact pricing is confirmed free on the call.

About this service

Septic treatments are additives designed to introduce bacteria or enzymes that help break down organic waste inside the tank. While not a replacement for routine pumping, some homeowners use them to keep the biological process active. You might consider these if you use a lot of harsh cleaners that kill off the natural bacteria your system needs to function. They are generally an affordable monthly or quarterly supplement to your maintenance routine.
