I'm doing my own stairs remod - long story short, I'm regretting it. It looked deceptively easy, but I've regretted it and I have a bunch of little errors that are adding up.
One such mistake is that the skirt board is in, can't be removed and it protrudes from the wall by a little less than 1/4 of an inch.
How would someone who knows what they're doing try to get rid of this protrusion so it's flush with the wall it's against? I'm afraid sawing will be sloppy (especially if I do it). Would a belt sander work?
