Water damage is one of the most common causes of building
repairs. Not only are such repairs costly, but in many cases damage
is impossible to correct. Further, water intrusion in building structures
creates a favorable environment for the development of other serious
problems – such as mold, dry rot and decay. Proper water management
is the essential first step in controlling mold, dry rot and decay.
The easiest way for water to get into structures is through
windows, doors and other detail areas where no water protective
building components are installed. To minimize the possibility of water
entry, all critical detail areas should be flashed using the appropriate
flashing materials and following the proper installation techniques.
