A door needs to be installed in a load-bearing interior wall (sand-lime brick) of an old two-family house (built in 1976) (positive test by a structural engineer).
Questions:
1. Do I saw or cut in the doorway? Disadvantage of sawing: Significant accumulation of dust, as it is impossible to work with water, because one side of the parquet floor. Disadvantage of chiseling: Vibrations? Unclean grooving. The work should be done by a specialized company. What method of penetration is advised by an experienced builder?
2. The ceiling must be secured with steel supports. Should you expect damage to the parquet floor, even if the support is on a thick wooden plank? In the demolition area, the parquet surface is usually protected by planks.
