White mold solutions

I have a cabin with a 30 x 32 crawl space with cement floor. In 20 years, I have never had a mold /moisture problem but this year I discovered mold on the ceiling between the floor joists. Remediation will cost about $2700. Guy recommends a dehumidifier installed with pump for about $1200. What about a vapor barrier over the cement floor instead of a dehumidifier? I could do that myself. Actually couldprobably do the dehumidifier myself but rather have a professional install for drainage into the sewer line. I'm concerned that if I don't put a dehumidifier in and just use a vapor barrier, the mold will come back and I'll have to dish out another $2700 for remediation. Vapor barrier would save the monthly cost of dehumidifier. Any advice would be appreciated. Thanks

I have used vapor barriers with great success. And, a barrier is much more energy efficient than running a dehumidifier forever.

You may be able to use a generic dehumidifier with the drain line run to outside.
You'd only need to run the dehumidifier under extremely high humidity periods.

Thanks...not really sure I want to take a chance on the moisture barrier and maybe have to remediate again for $2700. I am thinking that the dehumidifier may need to be run mostly in the summer when it gets hotter. The climate north of Two Harbors, Mn is cooler but still can get humid and hot in the summer.

Thanks Dane....not sure how I will go yet. Like I said to Pete, hate to just put a vapor barrier down and take a chance that will work. I don't think they are cheap either!
