I can understand HI’s not charging because the feel they are not up to speed with the camera use and have yet to acquire the needed training.
However, this is not about taking a snapshot and calling it “moisture”. There is a considerable increase in time to evaluate, report and further evaluate.
If you can’t simply market your additional time required to perform the added service, do not invest in the equipment.
We decide to purchase equipment based on “return of investment” potential. But actually it should be based upon the additional work you will be offering which you should be able to charge for.
How much more of your time can you charge for? Offering a service requires equipment (Your truck, flashlight, phone, computer, training). It’s the cost of business. So, if your going to pull out that IR Cam, you should be charging just like any other service you perform.
