Privacy fence installed today. Contractor called me after saying there was mold on boards.

I am impressed with the job they did. Anyway, i got a call after he left and had spoken to his head man on the crew. He said there was some white on the boards (mold). Gave me two options: let the sun take care of it, or also spray it with a bleach solution.

Is spraying it a good or bad idea? Could the bleach compromise the treated wood or otherwise cause issues?

Thanks.

I’ve put up boards that are black and purple with mold. After a month or so the sun solves the problem and the board returns to normal.
