I have a modular house (Simplex)that is four years old. Over the past tow years I have black marks that have appeared across the ceiling starting at the walls and moving to the center. Also, the marks appear around the wall outlets and switch plates. The marks seems to be a oily dust the can be cleaned but it is extremely difficult. This dust also is all over the window frames but not as heavy. The heating system is electrical baseboard with and ETS. Painting covers the marks but they return. What cold the source of this dust be and what measures can I take to fix it? I also want to note that the isnulation in my attic is turning black with what may be the same dust. I am very concerned not oly because of the appearance but possible healthe issues. The company who placed my house has said that it is now out of warranty. I have contacted the manufacturer, but to date I have not heard from them.

I really hate to tell you this, but I'd have to say you're having mildew problems. With you having baseboard heaters, your place is very dry, right? Mildew is not very picky, it can happen whether your place is too dry or too humid.

I'd suggest getting a humidifier. See if you can borrow one and try it out for a while and see if it makes any difference. If I'm right, then it should.

If you can't borrow one, and this is convienant for you [as long as you don't have little walkers toddling in the house] then you can put a pan with water in it on top of your baseboard heater. Soup cans with water will work as well if your heaters aren't wide enough for anything bigger.

If you have any paper work from the company that did your house, I'd read it carefully. Your warranty may not be expired, they may be just telling you this so they don't have to pay for anything. Unfortunately, a lot of places do this to people [we used to deal with an insurance company that did that to us a lot, but we read the fine print and knew better].

The previous reply is wrong. Mildew needs to have a humid environment to grow. Adding humidity will make the problem worse, if that is what it is.

But I am betting tht you burn candles in your house and the sooty film is from the wicks.

Might be wise to have the furnace checked......(is it a combustion type?)

Any Combustion/fireplace?

Modulars tend to be really "tight"....... air/ventilation.......

Buy a CO2 detector

Good thought Dick, but electrical heat doesn't often make much soot. Maybe there is a fireplace too....
