Site Visit

We offer site visits that are handled by the experts on our Diagnostic Team. If you are interested in a site visit, please contact us at the email below. Our site visit process starts with a consultation by our team. We will go over your concerns and then determine if a site visit is needed.

We can often resolve inquiries without the need for a site visit, but we are happy to come out to get to the bottom of an issue! The cost of a site visit is $20, and we ask that you do not submit a payment until you have heard from a member of our team. Once you have heard from us, you can pay using the button below!
