    Your guys were great-courteous, diligent and careful. I coughed alot after they left. I assumed I was catching a cold. I went to Winston Salem and my cough went away while I was there. When I came home yesterday afternoon my cough returned almost immediately. It prevented my sleeping. There appears to be a thin layer of grey dust inside the house. I cleaned the heat pump return over the weekend and it has accumulated grey dust on it. There is dust on the window sills, and on the furniture. I'm returning to Winston Salem this morning, and I'd appreciate your calling me when you have time. I'm sure there's no reason for concern. I don't mind cleaning the dust at all. I'm just concerned about my cough and my silly animals. Thanks.

  • Project Location: Hickory, NC
    Service Master of Hickory had to remove all the insulation on my sub floor in the crawl space under the house in a water heater rupture situation. It is now time in the process to replace that insulation as they should have finished the mold remediation sometime today. They recommended that I contact you for the insulation replacement, so I guess I need an estimate. We are not currently living in the house but I've given you my cell so we can arrange a time. Thanks,

    I am only interested in getting estimate on a tankless water heater, we have a 1650 ft ranch with 2 baths, the area under the house is low where our current water heater is , so it is too small, but no room to put a larger one. could you give us an estimate, we live in hickory. It may be a few months before we are at a point to consider starting work.
