Any honest mold remediation companies?

I've used Water Damage DMV after leaks, and they painted the rafters with some kind of anti mold paint.

You likely do not need remediation for such a small amount, unless there is evidence of a broader issue. And I would not file a homeowners claim for something minor- our homeowners insurance just dropped us after a mold remediation claim.

Try one of these -

Yes, you should control condensation and humidity.

If you do ever need remediation, Valor Mold is good.

I’ve done mold remediation before in an attic and don’t remember it being an issue when selling the house. The key to keeping mold out of the attic was the fan.

As for vendors, I had a positive experience with MoldGone.

Second this, MoldGone was excellent (we had water coming in through our exterior bricks). Very throrough, problem solved.

The rest of my attic was mold free, and I looked carefully all around the air handler etc for leaks, and no water. I removed the mold, and it didn’t return for several months (last checked in June when changing AC filters). Yesterday I went up there to check, and saw the same areas where I had either cut off the spray foam or wiped it with a little mold growth. Again, I removed it, but I’m guessing I need to do more than that. Any suggestions of what the culprit could be? Humidity? It weird because it’s really only up high above where the hatch entrance is. I don’t see any mold on my closet ceiling where I access the attic. I assume now I need call in a mold remediation company to help figure out the issue and fix it, but I want someone honest. Any suggestions?

50/50 bleach, or 100% storebought bleach. It's already highly dilluted to around 5-6% sodium hypochlorate. Spray it on there. Repeat a few days later. Presto no more mold. If humidity is an issue, then solve that to prevent future growths of mold. There are always mold spores floating around in the air, but they need moisture/food to grow.

Valor Mold were knowledgeable and honest. See their website for what to do and the case studies. They follow the certification standard.

Proper dehumidifier (these cost $1-$5k not hundreds) keeping humidity at around 40 and not above 50 helps.

I suspect what’s happening is foam abutting wood is creating condensation on the other side, which is a known foam defect (and has made spray foamed attic houses uninsurable in some countries).

Interesting theory. So even though I only see a small area with mold, it’s likely all over between roof and first layer of spray foam?

If you do feel this requires external help and don't want to get scammed, a licensed mold assessor who will provide an independent plan and does not provide remediation services is a decent bet: they have no incentive to recommend unnecessary work. It's possible their consult will end up being a waste of money if they find nothing, or propose obvious solutions per the above, but a ~$600 consult fee might be worth the piece of mind, and good ones will spot trickier issues with thermal cameras, etc. For example, DC has a list of licensed assessors/remediators. Firms like Valor and MoldGone are on it, but they also provide remediation, so I might skip them to get a fully independent assessment.
