Do I need to report to the property if I change the window without changing the size?

First of all, when we decide to replace the original window, we must file with the property in advance to avoid decoration disputes later. Generally, if the original window size is not changed, the general property can be put on record.

Before design and processing, you need to contact a professional door and window manufacturer for on-site measurement. In order to facilitate the installation of new windows in the later period, a uniform gap should be left around the original window opening, preferably around10 mm.

After determining the size of the new window, we can remove the original window and clean up the raw materials around the original window. If the section around the original window is not particularly flat, we need to re-level the window opening with cement mortar, which is also convenient for our later installation project.
