Before calling any of them, pull the property's recorded as-built if one exists. It gives tank size, lid location and drainfield layout, which is the difference between a quoted job and an hourly dig.

Listing here is not an endorsement. We take no fee from any company on this page, we are not affiliated with them, and being listed does not mean the business is a customer of ours. Fields shown are limited to what we actually hold: no street address, hours or license numbers are shown unless we hold them, and none are invented.

Local septic work: pumping, installation, design, inspection, repair

Pumping. A pumper needs the lid location and tank capacity. Locating a buried lid without the recorded as-built is billed as labor.
Installation. A permit before work starts, an inspection while the system is open, and a final as-built submitted at completion, which is what ends up in the county file.
Design. Design flow from bedroom count, a soil and site evaluation, tank sizing and the required setbacks. On a lot with an existing permit, the original soil work is often already on file.
Inspection. Lenders and many counties require one at sale or transfer. Inspectors start from the recorded as-built; without it they are probing blind.
Repair. Starts from the existing as-built, since the current tank, field and any reserve area constrain what can be rebuilt.
