Q: Why are there faded areas on the carpeting around the windows on one side of my house?
A: This is probably a sign of damage from ultraviolet rays. The house likely has more intense exposure to the sun on one side of your home, and the UV rays are entering through your windows or doors. You may want to consider replacement with more energy-efficient windows that contain Low-E coatings on the glass to inhibit the transfer of UV rays. Otherwise, protect the carpet with blinds or shutters.
