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
The drain field is where water from your tank is filtered into the soil. If the grass over the field is constantly wet or if your toilets are backing up, you may need a repair. This involves addressing issues like clogged pipes or soil compaction. Because these repairs involve excavation, the price fluctuates based on the scale of the damage and accessibility. Exact pricing confirmed free on the call.
