Finally got all my stair treads in place, I have a few gaps where the tread and sidewall meet. Majority of gaps are less than 1/8", most are fine. Sidewall is drywall. One gap is 1/4" which I think is too wide for caulk. Do I fill in with wood filler or caulk? Gone too far to yank the step out. Any advice would be appreciated.
