Our leaky roof led to mold growth that was discovered after the emergency response crews came and removed the affected areas of drywall. They then told us that we had to take care of the mold so that they could continue with the repairs.
After looking through many companies and getting wildly variable quotes, we chose to go with Mold Guys. Kay was very friendly and helpful over the phone and Ross was the only guy that did a thorough inspection of the problem, instead of pointing at areas with a laser and constantly saying "that's mold". The visit was not free (150$) but it had a rebate option, which you will get, because after Ross comes at your house, you will choose them on top of any other company. His approach was much more honest and proper than all the other people that came in the house (a total of 5). He took the time to look in close detail and sure enough the problem was not as big as other "experts" suggested (they just wanted more work/$$$).
The work was done over a couple of days and despite a small delay in getting the spore counts to a level that would make the repair contractors unable to claim inability to commence work, the service that the Mold Guy offered us was very good. They were always available to talk on the phone and very prompt on e-mail correspondence, addressing any issues that we had.
If someone asks me about mold issues, Mold Guy will definitely be my recommendation.
