How to Spot Rotting Window Frames Before It Spreads

Rotting window frames usually start quietly. If you wait until the trim is falling apart, the damage has often spread beyond the visible spot.

Homeowners also ask how much does window replacement cost in Lexington SC, and the answer depends on size, material, glass package, and installation method.
