Why Window Condensation Problems Happen in Rock Hill, SC Homes

In Rock Hill, SC homes, condensation on windows is often more than a nuisance, because it can be the first sign that indoor humidity, air leakage, or an aging window system is working against the house.

Where the water really comes from
