Remember, the only 'dumb' question is the unasked question. Make sure the property owner knows the exact date, time and estimated duration of the home inspection. Otherwise it is impossible to truly test the operational condition of the systems. It is helpful to have all sinks, basins, and tubs empty. The inspection report is provided after the inspection is completed.
Payment is due upon completion of the inspection.
This is your assurance that the inspector will not use the inspection to solicit repair work for himself or any particular contractor.
