William Yap 0 Report post Posted March 27, 2018 I need help on the partition wall. I want to mount a sliding door, after all the renovations done up. The contractor say my wall is partition ceiling and require to do strengthening. Generally how much to do up the strengthening? Do i have to tear down the wall, and redo the partition again? PS I just did up the wall and painted. Sighz. Share this post Link to post Share on other sites
