We do offer free phone estimates for Rooter Service and Septic Pumping as this is a standard service.
We do give a 30 day guarantee on Rooter Service. Septic pumping is pretty cut and dry, we pump out the tank and haul it off. If we do a repair it has a 1 year guarantee.
If you do not have any smells and or gurgles in house is one way to know the tank is working properly. But the best way to know for sure is to dig it up and if the level of the water/waste is below the baffle coming into tank and leaving the tank it is working properly.
We recommend to pump a septic tank every 3 to 5 years depending on how many people live in the house.
