The gap between wall and hardwood floor, which caulk to use??

Hi, all:
Sorry I'm a beginner level DIY-er. Recently we had our hardwood floor sanded and refinished. After it was done, we found that the hardwood floor now has a "gap" at the edges of the floor and the wall (probably drywall, not sure what is the material). I'm thinking of doing some caulking but don't know which kind of caulk I should apply, any suggestions? Thanks!

A gap is necessary for expansion in humid weather. Dont you have baseboard moulding over the floor. Caulk it tight and it is possible to have problems. Someone instaled a wood floor where I now live in low humidity to the wall, in summer it buckled up 4 inches, It had to be junked.

Moulding should be installed to cover the gap and nailed to the wall and not the floor so the hardwood can expand.

Do not caulk there. It will be an ugly mess. Add quarter-round. -B

How big a gap, and where does it go? If it's a big enough gap, and it leads to an air-space, or down through the subfloor, or anywhere else it's likely to be a entrypoint for drafts of vermin, then you might stuff it with weatherstripping and THEN cover it with molding.
