I live in a new home built a year ago. I noticed a little frost on the inside of my window today. Is this a sign of cheap windows?
Not necessarily, it could be the sign of poor installation and sealing.
Here ia a $1.5 M house with top of the line windows installed poorly.See the blue at the bottom the infiltration caused condensation. The builder re-sealed the window.The window installation should involve a wrap in the opening along with extra in the corners .After the wrap is installed the its cut in an X shape from corner to corner,after the tag ends are pulled into the opening the corners sometimesget missed or thought to be fine or just poorly installed...
