when your SA told you that they do it in house, it may not necessarily mean their technician does this job. he might call the mobile repair company to come "in house" and do it for them. many dealership normally sub out things like windshield repair, wheel balancing, alignment, paintless dent repair...

in fact, I would doubt their technician's ability to replace windshield unless they have bodyshop. those mobile guys are more experienced in replacing this things. (you probably think they do only honda...that's wrong)
