You eventually notice only-increasing rust, discoloration, deteriorating mortar joints, spalling, shaling, fading wallpaper or a damaged crown with a growing crack or aperture. Don’t fix on your own. Get help.
Many don’t realize that damaged chimneys are not merely damaged chimneys: They are, in fact, potential fire hazards of the worst form. When any chimney stains or discolors itself in white, for instance, many call the result Efflorescence. A basic cleaning and wipe-down of the top layer showing is easy and simple to perform, though that alone does not fix the problem at the root source: Moisture build-up is causing the white coloring. When unchecked or unresolved at the first noticed onset, the chimney will deteriorate prematurely and moisture problems will only increase and become more difficult to obliterate.
