To Caulk or Not to Caulk?


Written by Staff Writer

Applying caulk to stop leaks is not always a good thing.  Sometimes it makes matters worse by trapping water in the building façade instead of letting it drain.  

Here are a few areas where NOT to caulk:

*Along window or door head lintels on brick facades – leads to advanced corrosion of the steel support and either rotated/deflected steel or cracked bricks.

*Soffit (ceiling) of elevated concrete slabs (i.e. balconies, parking garage slabs) – traps water in the concrete and accelerates corrosion of the embedded steel and deterioration of the concrete

*Over/covering window weep holes – prevents windows from draining properly
