Dear Glenn: Would you please tell me again the name of the floor steamer you recommended on one of your earlier shows? I was listening to you while driving and was unable to write it down.

Dear Wendy: The name of the product is called the Haan Floor Sanitizer, (877) 422-6347, www.haanusa.com. It is available at Target and Macy's.

Dear Glenn: We purchased a home in Livonia in October 2009. The home was built in 1967. The home had been vacant for two years. A month later, we began noticing a moldy smell emitting from master bathroom.

It became progressively stronger as the days went on, but we cannot determine exactly where the smell is originating from. The odor has become so strong, that I can now smell it as I enter the house after work each day. It seems to be coming from the drain on the floor of the shower.

I have poured bleach down the drain and washed down the entire shower, but the smell remains. I had two plumbers come out to help us, but they all said the same thing; they have absolutely no idea where the smell is coming from.

We asked about the vent being plugged, but they said since the drains are flowing, that's not the problem. One suggested that we reseal the toilet because it is not tight to the floor, and reseal the shower grout and drain.

I am concerned that if it is a mold issue, we will be sealing in the smell and just masking the problem. We are stumped, and I cannot tolerate the smell any longer! And I don't think it is healthy for us to breathe in this smell every night.

I am ready to rip out the entire bathroom. Can you offer us any suggestions? We really need help now.

Dear Karyl: OK, now we need to take air samples and moisture readings. Call Sanit-Air, (888) 778-7324, www.sanit-air.com. Ask for Connie Morbach.

Dear Glenn: On one of your shows you talked about filling the legs of pantyhose with something to prevent ice dams. I can't remember what it was. My husband says I'm crazy and that it's rock salt, but that is not what you said to fill the nylons with. Thanks very much, and I love the show.

Mary, via e-mail

Dear Mary: Thanks for being such a good listener. The product that you want to stick in the pantyhose is calcium chloride. It will help melt the ice that causes the ice dams and will not damage the gutters. More information is on my Web site; type in "Ice Dams" or "Gutters."

Dear Glenn: We have a split-level home built in 1977 with no problems until the last two years. Since then, we have added more blown-in insulation, new windows and a heat pump. We have also replaced roof vents with two turbine vents. We also installed three eave vents on each side of the house.

After a cold day or night, and a warmer day, the south side of the house sweats moisture under the 12-inch lap siding from one end of the house to above the heat pump and, except for about 6 feet, to the other end of the house. Some areas are worse than others. The house has a thickness of black material under the lap siding, and the walls are insulated with faced fiberglass insulation. What can I do?

Dear Rocky: First, get a blower test performed. This will probably tell you that the house is too tight. With all the new upgrades you did to the home, there is not enough combustion air coming in. But you can fix this problem by installing either a Skuttle Model 216, (800) 848-9786, www.skuttle.com, or an Equaliz-Air, (734) 462-1033, www.equaliz-air.com.

Either product will help bring fresh air into the home and cut down on the moisture problem.
