why would a house have condensation build up on the inside?

Question

the walls actually weep have a bad problem with mildew on the walls on the windows there is paneling on the walls is happening in every room of the house is older house that was added on to two seperate attic entrances

Answer 1

There are a lot of sources of humidity inside the house: cooking, showering, bathing, laundry, even just breathing out will add to the moisture in the air. And of course, many people use humidifiers in the winter. When this humid air hits a cold surface, the moisture will condense into droplets. This is most obvious on window glass where the condensate will cause the glass to fog up, but it will happen on any cold surface. The cause in your house is probably single-pane windows and inadequate insulation in the walls.

Your immediate fix is to lower the humidity and perhaps raise the temperature in the house. Turn down the humidifier if you are using one. Run your exhaust fans in the bathrooms and kitchen. You may even need to get a dehumidifier to remove the moisture from the air. Small electronic humidity sensors with digital readouts are available to help monitor the humidity.

In the long term, you should have double pane windows installed, and have your walls and attic insulated. Not only will it eliminate this problem, but your house will be more comfortable and quieter in both summer and winter, and you'll save on your utility bills.

Answer 2

The house has too much moisture in it and it has no where to go, which means that the ground surrounding the house could be higher than the floors which lets water seep through plaster, wood, cement any porous surface. If not taken care of the occupants of the house could become very ill due to the mold spores that they are breathing, especially young children. Contact your insurance company and you may have to have some environmental testing done on your home. Good luck

Answer 3

The problem is poor air circulation,check that the insulation in your attic isn't touching the roof at the top of the walls.Air should be able to move from the soffit area through to the peak of the roof.Here in Ontario,"Moore Vents",must be installed to pass building inspection.

Answer 4

What type of air conditioning is in the house? I have seen this problem, when someone installed too big an air conditioner in their house. They tried to save money buy doing it themselves, and it ended up costing them dearly when their children got sick from the mildew!

Answer 5

it sounds like your house is not ventilated enough for good air circulation check your soffit vents or ridge vents for your roof
also check for other causes like bad dryer vent or if you have a humidifier turn it down
a quick fix would be a dehumidifier to pull the moisture out of the house

Answer 6

The humidity in the house is much too high compared to the humidity outside and/or you have poorly insulated walls and inferior windows.

Answer 7

Way to much humidity and a ventilation problem. Call a relaible HVAC dealer and have them check the system out.

Answer 8

poor ventilation. also your house will sweat on the inside and the windows will condensate real bad if you do not have your dryer vented to the outside. check your hoses on your dryer make sure they are well connected..

Answer 9

odds are on an older house,roofing felt was used to wrap the house instead of tyvek. tyvek allows your house to breath so to speak. it lets moisture out but doesnt allow moisture in.

Answer 10

it sounds like you have several air hole some where cause that is what causes condensation the cold and hot mixed together it may also be caused by sinder blocks, for some reason that will also cause that .........Good Luck
