First winter in the new house. All the windows seem to be sweating a lot and even have ice on the bottom of them. Looking closer, there is mold near the wood. Any ideas on what to do to prevent or help?

Also, noticed on the basement wall, there is a wetness on the wall. Almost like it is coming from inside of the wall. I can’t post a photo since it is too large.

This is a good overview and feel free to search more but it is basically because of the humidity in your home.

Do you have an ERV? Most newer homes do.

Do you have a humidifier?

At the temperatures out now (negative whatever) it is nearly impossible to prevent condensation. I try to wipe it up as much as possible (weekly?) to prevent mold growth. I also have played with my ERV and whole house humidifier settings and have found a pretty good balance for both that gives me enough humidity without causing condensation on most of my windows. Depending on how bad it is and your particular situation you may need to do more before it becomes a bigger problem. I’m no expert so hopefully someone can elaborate.

The wetness on the wall in the basement scares me. You should definitely get more input from someone here or a professional.
