This Is For Grand Rapids Homeowners Who Experience Dust Troubles? "Within two days, I have dust sitting on all my surfaces..!!"

"My curtains become filthy within a week after taking them down and washing them. Yet there is only one small vent near them and I don't see much dust there. I had my vents inspected before we put in the new equipment and was told I did not have any problem. WeDustMe have checked as far as we can see and see no build up or debris in the vents. What could be causing this problem and how can we fix it?"

Maybe you can relate to this homeowner. Persistent dust is not only annoying, but can also be a health hazard. The causes of dust in a house are often difficult to track down, since there are so many possibilities but they contribute to your indoor air quality.

Attic insulation is a common source for dust problems. Some types of cellulose seem to be "dustier" than most other products on the market today.So let's assume the source of the dust is the attic. In order for this to be true, there has to be a pathway for the dust to get from the attic into the rest of the house, and there must be some driving force to move it. The most likely scenario would be leaky return ducts in the attic sucking in the dust and moving it throughout the house via the heating system, except that your ducts are in the basement.

What you need to do is look for holes between the attic and the living space. Often there are large holes, such as the unsealed tops of plumbing chaseways, dropped ceilings above closets or kitchen cabinets, attic access hatches that don't seal well, around and over recessed light fixtures, around chimneys, big gaps around plumbing, etc. There are also smaller holes and gaps between the drywall and the top plate of the walls, around wiring penetrations, etc. All of these holes and gaps are potential pathways for dust to be sucked into the house from the attic.
