Start with the address, whether you need a new well or a pump, and the problem: no water, weak water, a planned house, or an unused well to plug. Ask if they take that job at that land this season.
Ask what is included: locating the well, pulling the pump, drilling footage, casing, and a well log. Ask what is extra: after-hours, a long drive, or a dry hole. Write the number down.
Ask who files the well log with the Water Resources Board. This directory does not rate companies and does not invent reviews.
Keep the company name, phone, date, and any well-log number. The next owner of the house will want that record. If the company is also on a sister directory, that is a separate credential — ask which job they are quoting.
General information for Oklahoma homeowners, not legal advice and not a booking. Compare companies on the directory and confirm the job directly.
