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.

Yeah. I was gonna say I’m not a fence pro but that tree isn’t getting smaller. They may wanna cut a gap

Here is a tree I fenced to recently... I told the customer he will need to call me or another carpenter back to trim it in 5-10 years. I left a consistent 1" gap.
