I had a water heater rupture, left water standing everywhere in the unit where it sat, and in three of five rooms in another unit. They were at my place before the day was out, cleaned up all the water, tore out all the affected materials and had several air movers/dehumidifiers going to dry out the place quickly.
I was able to begin the rehab about a week after the mishap, which ultimately saved me in lost rent. These guys really know what they are doing!
