Anyone have a recommendation for someone to install our dog door into an exterior wall? I have the door and started the installation, but when I cut the inside of the wall, to my surprise there was not 1 but 4 studs in the way. I could've handled 1, but when 4 are nailed together, it must be a pretty important stud. I'd rather not tackle trying to frame out this door and put in a header and remove these 4 studs myself. Thanks, Jason
