If possible, postpone the repair until next year.
If you still need to do it, don't start straightaway at your South sector. Start from SouthWest or South East slowly going toward South. This will reduce the impact. Find a good day to start.
Put a "5 elements arrangements" in your South sector, you should have it in your 2028 FengShui essential 2018WuXuDogYear.pdf.
Monthly 3 killing is also in the South between 00:14am 07/12/2020 -- 11:18am 05/01/2021 5 1 戊 子 WuZi month. Avoid renovating during this time.
Cheers.
