回复：Thanks. Guess you mean 2 labor days if DIY, right?

More likely 4.
-Cut and take out old rags and felt pads: 1/2 day
-Remove all tack strips: 1 day
-Remove staples (including those from previous carpet installations):
2 days. This has to be done meticulously, otherwise the floor won't be flat. Really back-breaking.

To top that: lay in bed and recover 2 days.
