Remeber back with the Kanima problem at the night club and stiles made the ring of mountain ash, and the only way derek could cross it was when stiles broke it. Also when the McCalls set up a new securtity system and how it was only activated when Mellissa smashed the urn of mountain ash and it blocked the door. At the boat house, when Lydia threw the mountain ash, it formed a line along the water/wood border and this completed the circut I think the question was more along the lines of, how did they get in if the place was made of rowan (mountain ash wood). A reasonable question, considering we never see lines of mountain ash at the vet clinic, yet noone seems able to pass the front desk (except for Scott; though presumably Deaton lets him in).
