Find a Cure for Damp Brick Walls

Illinois was the wettest state in the nation in June with 8.97 inches of water falling – breaking the record set back in 1895. Chicago’s Midway airport recorded more than 10 inches of rain. July is also shaping up to be wetter than normal.

With so much rain, issues with damp walls that may have quickly disappeared in the past, can persist. While no one is  happy to have to contend with a water issue, taking care of the dampness before it becomes a bigger problem is always the best strategy.

Water that seeps through walls at any point is called  penetrating damp vs. dampness in the lower part of ground floor walls which is called rising damp. Tuckpointing, brick repair and caulking can often help prevent penetrating damp. A penetrating damp patch may appear when strong winds derive rain against the house and disappear after the rain.  If a whole wall is damp, it may be that the brick has become porous with age.  Telltale signs of penetrating damp includes blotchy patches on the wall, wet and crumbly plaster, mildew on the walls or even water on the surface. Check out the common symptoms and cures.
