Wondering if it is time to renovate your windows and doors but unsure how to decide? In this article, we look at some visible and invisible criteria to consider when thinking about windows or doors replacement. Not every aluminium renovation is the same. Replacing windows and doors can either be categorised as a light or heavy renovation. A heavy window replacement renovation means the complete window system is broken out and replaced.
