Q. How often will I need to caulk my Centennial windows?

A. Caulking should be inspected annually.  Building materials, such as the frame of the house, expand and contract due to changes in weather, which can cause the caulking to stretch beyond its limit. Road salt can also affect sealants.

Q. What is condensation?
