Staircase repair
 

Gaps along the molding 3/4 in. Wats the best way to temporary fix. Then to plan to complete.

Post makes little since and without a picture not even sure where this moulding is that you have questions about.

A littlle llonger description is needed---What molding? There is a skirt board along the wall --is that the one you are concerned with?

What gaps I don't see no gaps. I don't know of many temporary fixes for gaps that don't involve covering the gap with molding. Bit more info please, tj, pics are nice, easier to take pic and see details than describe and comprehend discription.
