What is a dehumidifier?

A dehumidifier is an appliance that removes moisture from the air.

What are the signs that I need a dehumidifier?

There are a number of signs that you might need a dehumidifier. Below are a few that you can check for in your own home:

Condensation on Windows or Doors
You may have condensation on your windows or doors. You will see water beading or fog/vapor on the glass of your windows. This moisture will eventually rot the wood and will also allow mold to grow.

Mold Spots
You may also see mold spots on your ceiling or the corners of your walls. Moisture rises so you will often see evidence of mold or the beginning of mold where the walls meet the ceiling.

Musty Odors
A musty odor is another indicator that there is too much moisture in your house. Often these smells will come from a basement, crawl space, laundry room, entrance or garage. Musty or moldy smelling towels and bedding will let you know that your laundry room is one place where moisture is too heavy.

Water Level Marks
A lot of homes have reoccurring spring water run-off. This results in a damp basement where you will see white or grey water level marks.

Changes in Paint or Wallpaper
You can see blistering paint or peeling wallpaper. When there is excess moisture in the air it can penetrate the wall. It then turns to steam and will cause your paint and wallpaper to loose adhesion. This will result in bubbles or peels.

Creaky Doors, Windows, Floors, Etc.
The last thing you might witness is creaky doors/windows/floors etc. As wood absorbs moisture it expands. This causes joints and screws and the structural frame of your house to loosen.

Any or all of these things can be evidence of too much moisture in your home. New and remodeled homes have better insulation than ever before. This cuts your energy costs overall but it also creates less air flow and therefore traps humidity, so while you are saving money on gas/oil/electricity you may be creating another problem for yourself that, left unchecked, can lead to costly repairs.


If you see any of these signs it is best to check the humidity levels in your home. You can do so by purchasing a hydrometer, calling us, or requesting service online.
