We found a good amount of mold in our crawl space this summer and called Kefficient to give us an estimate on remediation. Out of three estimates, they were the best price and very friendly and knowledgeable! They came out a couple weeks later and completed the remediation in one day. There was no smell in the house from the hydrogen peroxide cleaning solution. Also, I had previously removed the old insulation and had it in about 25 trash bags in the yard; they removed it without me even asking for that! This is a great company and I highly recommend them!
