We have had a lot of rain in the Chicagoland area, and warm, wet winters for the past two years. As a result, many masonry buildings (Chicago is primarily a masonry town. Remember the Chicago Fire?) have been having waster intrusion problems. Recently, I have noticed that even well constructed buildings have been suffering from a lot of water intrusion issues above windows and doors.
So, I researched and wrote this article.
