Many people wonder at what point a window renovation is actually necessary. Certain tell-tale clues will tell you, for example if your windows let strong drafts in.

The paint peeling off a wooden window will be visible to the naked eye. Discoloration may become visible on a PVC window, indicating that the luminance of the frame is dulling.
