how to repair cracks and gaps on wood

I damaged the wooden frame of my fireplace while undercutting it to make room for laminate floor. (picture attached). How do I fix the holes? What material to use? filler or caulk?

Bondo makes a wood filler that is a 2 part mix that sets up chemically. You apply it to the area in question, overfill by just a bit and sand to blend into the surrounding wood. Don't apply too thick or you will be sanding for the next 2 years. It can be found in the glue section of the big box stores near the paint dept.

I use Durham's Rock Hard water puddy for this.
It's cheaper and less messy then bondo.
Any hardware, of box store will have it.
Just add water and mix until if looks like peanut butter.
Sands like wood.

I like Durham's Rock Hard Putty but it can be a bear to sand. Most any wood filler will work, even spackling or joint compound although rock hard or bondo will be more resistant against damage. These fillers are for the damage only. If you want to get rid of the gap between the floor and wood - use caulking.

Welcome to the forums Rick!

The oil idea might work, but there are enough gaps in the floor and sub-floor that I'd be worried about ending up with drips all over the items in the basement
What oil idea

I think you are mixing forum posts up. No one here has mentioned "expanding" wood with oil. The most logical solution would be to caulk the gap. Caulking is flexible and won't crack with variations in floor movement, if any.

Durham's RockHard expands slightly as it cures. A filler is needed for the chipped wood BUT should not be used for the gap between the wood and the floor!! That is what caulking is for
