How We Price
The number is quoted before the truck leaves and does not move on site without your approval. Two things add cost and we ask about both on the phone: a lid buried well below grade, and an access point we have to dig for because no riser was installed. Pumping pricing.
How We Diagnose
Repairs get quoted on an empty tank, never from the driveway. Liquid level against the outlet invert separates a tank or filter fault from a drain field fault, and that distinction is the difference between a few hundred dollars and a system replacement.
