Some people like vines growing up the brick of their home, it gives them a fairy tale look. Eventually the vines over grow and cover the entire brick wall. Your longer vines remain attached to your brick, and start to embed their tendrils and roots into the brick or mortar. Old vines are more developed and are capable of weakening your brick or widening the cracks in your brick joints. If you have aged brick this is vulnerable to vine related damage. You will have to remove old vines from your brick to extend your bricks lifespan.
