I have circles appearing on my walls, like damp patches, what are they? and what is causing them?

Answer 1

If you have a problem with drink there is a possibility they are not really there especially if they are pink in colour.

Answer 2

Hey there ...Kooltymz here.
You haven't given me much to work with. (Interior wall/exterior wall, first floor/second/third, detached garage/attached garage/actual living space, air-handler in the attic/ somewhere else etc.) However, if it looks like damp spots, then that's what it is. Unfortunately I can't easily identify what is causing these spots pretty much for lack of information.
Based on what little info that I do have I'm going to say that somehow somewhere you have water getting where you don't need it. Could be a bad roof, could be a clogged drainpan (something that I would definitely consider if the air-handler is in the attic. Could be that your windows are old and need at the very least to be re-caulked.
Keep in mind that a leak in one place is only an entry point. That is, although the leak is here, it may find a way to get all the way over there to the other side of the house.
You may have to open, at least one wall just to be able to track the water stain back to its' origin. It is a job that needs to be attacked rather promptly as this damp-spot casing water will in turn promote mold spore growth. Whether your damp spots have turned black from mold yet or not, I do not know. That it will, I do know.
Keep in mind that many a house in the U.S. has already been condemned based only on the mold issue certainly gives you cause for concern and immediate action.
Find the leak ...solve the cause of the problem.
You still have to kill the mold which means tearing the "wet spots" out and cleaning all your studs and remaining wall with "ZEP Mold and Mildew" cleaner(or an equivalent), if the mold is not set in so deep as to require the replacement of the studs and more of the wall (or walls) in question.
Get rid of it. Check your roof ....check your walls ... ckeck up near your soffits where the walls and the roof meet. Do your have rain gutters? Are your downspouts rotting through so as to allow a consentration of water to unnecessarily run down the walls?
So many things to check. You can save yourself money by searching yourself. Don't be afraid to use the garden hose on the walls outside or up on the roof. If it can't take the water, it can't take rain. Rain is always sneakier than you or I could ever be. If the ouside drain to your air conditioners drainpan is somehow plugged (no water coming out), clear it, and/ or call an a/c tech.
I could probably go on and on forever, but my ability to yak really won't help you much because it's just one of those thiongs that you can't do sitting here on the computer. Ya gots ta git ta work.
Good luck. (I'll kinda keep an eye out here in "Answers" in case the info I've shared with you doesn't work. Perhaps in that case you could supply me with more detailed info of your troubles. I'm sure I can help.)

Answer 3

It can be quite depressing to see and smell damp in your home, especially for a pregnant lady who may be worried about the home.Patches that don't dry out are usually caused by the wall getting wet frequently(like the area around the kitchen tiles) The wall you share with a neighbour will be similar construction to an exterior wall. When this happens the plaster becomes 'live' and it absorbs moisture so it will never dry. Usually the solution is to remove the plaster from this area and replaster it with new. Unfortunately landlords often don't like to do this as it costs them money! It is a job that needs to be done by a tradesman

Answer 4

Being in the drywall business for over 20 years Ive seen it all.There is deffinately a moisture problem going on there.If the "damp patches" were on the ceiling that would suggest a leak from above,,but being on the wall itself could also suggest that the walls are over insulated and the walls are sweating from inside.Over a period of time without treatment will lead to mold growing and further neglect to studs rotting away.I suggest consult a pro on this one.The long term cost to your health and home are at stake.

Answer 5

Just damp ? No color.. It could be mold. try some bleach (cut W/water). If it is really wet then it sounds like a leak or?? But U said "like damp patches" If it is mold . The cause; depends on your location, area of the house, air circulation,etc. I hope it isn't mold, cause some types are potentially hazardous to Ur health.

Answer 6

They could be Crop Circles moving indoors for the winter and as to whats the cause , the earths magnetism, UFOs, little men in flat caps, your guess is as good mine

Answer 7

You have a leak some where, usually from a bathroom. But if it is many walls it is time for a new roof.

Answer 8

Probably moisture bridging the cavity over dirty wall ties.

They need to be cut out and cleaned

Answer 9

i am going to guess and say its a exterior wall if so then you have voids in your insulation.sorry i am not as long winded as some of these people but ,you will find i am right .

Answer 10
