I have 3 questions about a staircase installation which I hope you can answer so that I can organise which order I need to have work completed in my extension.
1. Should the wall finishing (plastering) be done before a new staircase is installed?
2. Should the upper floor have been laid before the staircase is installed and if not should a floor board be put in at the top of the staircase before the staircase is installed.
3. Roughly how long should it take 2 builders to install a pre-made staircase.
Your help is greatly appreciated!
