Question: Do climbing hydrangea damage brick walls ?
Answer: Climbing hydrangeas attach themselves to supports with little rootlets. It's possible for these roots to grow into tiny spaces between the bricks and mortar of a brick building or wall. For this reason, it's highly recommended that you provide a trellis or other support for the vine to cling to. This will also help your plant remain healthier because of the air circulation afforded by a trellis installed a foot or two in front of the wall.
Best wishes with your landscape!
