I’ve removed one of those before. The removal usually takes less than a day. It’s the repair to the wall, baseboard, floor, painting, etc that takes the most time. You’ll have to figure it for yourself, but it’s more than a weeks job. If you work 9-5, you’ll be doing this in the weekends and it will take you more than a month.

Also, don’t remove it. Use it. They are really nice to have.
