Vines - The victims of this highly adaptive natural process are human-made surfaces, which become speckled and dull where the suckers used to be.
In addition, vines create a high-humidity atmosphere that allows mildew to flourish.
And birds can nest in heavy vine growth, creating their own special kind of soiling.
Repairing this kind of damage involves cleaning, killing mildew, and finishing with a protective wax that helps restore the etched texture and makes it easy to keep the surface clean by hosing.
Don't get us wrong. Vine-covered buildings look great. But be prepared for what you'll find if you ever tear them down.
