Anxiety during house repair

[Deleted member 141751]

I have 4 boys. Today a friend came to pull up carpet tack as we are redoing the floors. I gave the boys a treat and all but one went about acting normally, while there was loud bangs in the other room. One of my boys wasn't interested in his treat, was standing still and teeth chattering. Eventually he went to hide in a tunnel and fell asleep during the noise. He seemed anxious about it. What could I do to help him in the future? The boys are not in a room that is having the floor redone.

Could you close the door and perhaps cover their cage or part of it?

Yes the door to my room was closed and there won't be any kind of remodeling in my room. His companion was acting normal and not bothered by the noise, but I guess that means nothing to pigs.
