We were buying a new/ used home and wanted to make sure our new home was safe for our family. My three children all have respiratory issues at one level or another. We were revered to Twin Cities Mold Investigations by our Realtor.   Air samples were taken on all three floors plus 1 outside. The next afternoon we received a call from David to give us the great news. Our house had normal mold counts plus no toxic mold. This gave us great peace of mind and moved in the next week. Thanks for the Rush service and next day results. Tina W.   Stillwater, MN

I noticed what looked like mold on my kitchen ceiling. I contacted Twin Cities Mold Investigations immediately. David, who arrived on time and was very friendly and professional, ran some tests and discovered I did have mold spores. Some were toxic so I was very glad I called to have my home checked. The mold was caused by a leak in my roof which I have since repaired
