Concrete walls sweating

[Allie65]

Just moved into a villa. I noticed as I returned home that there was water along my floors besides both sides of my front door. A friendly neighbor came by and informed me that the walls were wet. There was water dripping from the door frame. Has anybody encountered this? I did notice a mildew smell outside.I thought it was the planters and had them emptied .Maybe its the sweaty walls?

It was the humidity change Friday. I just turned on fans in lanai where I saw it and next morning was better. Nothing to worry about.

Thank you

I had the exact same thing happen on Friday. It's rare, but nothing to worry about. It is just humidity.

First, I have heard of this good stuff. Thanks for posting.

sweating ? that's interesting .... i was thinking a broken sprinkler system head...

sweating ? that's interesting .... i was thinking a broken sprinkler system head... Or a head that is not aimed properly and spraying the walls or door?

[retiredguy123]

This was a very strange occurrence. It was caused by a combination of rain, wind, and humidity. The exterior concrete walls around my front door were covered with water from the floor to the ceiling, and water was dripping off of the door frame. There was no leak or sprinkler issue.

This is there same as a cold glass of ice tea (or a cold can of beer) sweating on a hot summer day. When the temperature of a surface is below dewpoint the moisture will condense on that surface.

All my walls and floors got damp on Friday too. The humidity was crazy. Ended up shutting all the windows, and running the AC, and it took care of it.

Interesting you mentioned this. A few days ago I had a door to door salesman stop. When I was talking to him outside my front door area I noticed the walls were really wet and the floor was wet along the bottom of the walls. It was the first time I noticed it. I do not have any mold and the sprinklers are not near the walls. They had to be sweating from the humidity outside.

I found this article on sweating concrete walls…

At least the walls aren’t bleeding 🩸

I had a call from a neighbor who thought her roof was leaking. It was not. The extreme changes we have been experiencing is causing condensation. In other words it is simply the dew point. Our concrete homes retain the cold on exterior surfaces. Then warm humid air is brought along with a new weather front and the result is condensation which can actual drip from the walls of your lanai, front porch and exterior walls too. This morning my windows are fogged. With the warmer weather today followed by the expected extreme drop in temperature tomorrow you can expect it to happen again. There really is nothing you can do about it.

Been in my villa more than a year in DeLuna have never seen this happen. Other than rain soaking the lanai in heavy storm. Will watch for sweating in future. Thanks.

[Allie65]

Ditto!

Thank you!

Our concrete walls in our lanai were soaked with water running down them. Shorted out my outlets and now have no power on lanai. Can I let them dry out or do I need an electrician? Yes, I tripped the breaker a few times.

I would turn off the breaker, remove the outlet covers, and use a hair dryer. Hopefully, they will start working again.

My husband is an air conditioning guy. And he said it's something more than just humidity.
he said you could put the air conditioning on fan and not auto and let it see if it can dry it out. otherwise you should have someone come and look at your roof and see what's going on. It should not be dripping wet humidity is different than dripping wet.

This is on the exterior of the house, so I don't understand how the air conditioner would do anything. Also, the problem has nothing to do with a roof leak. The exterior walls were wet from humidity.

Thanks for the link. Will watch for any mold.

After checking the gutters for leaks we figured out it must be condensation. Appreciate the verification

& again this morning

The breaker for our lanai tripped once and in addition to flipping the breaker in the elec box, we also had to press the reset button in the GFCI outlet in our garage. They are "connected" somehow.

It might seem unusual now, but we all know that WARM air holds more moisture. If you check, you can find out that the last 10 years worldwide are the WARMEST on record. The Gulf and ocean temperatures surrounding Florida, as measured by Climatologists, have been increasing each year. More moisture equals more dew-like sweating on doors, windows, and walls.

I didn't see any issues at my house, but walking around Lake Sumter Landing, it was weird that the sidewalk was wet everywhere but it wasn't raining. Even concrete under a roof or awning was wet, very odd situation. (Been in Florida since 1984).

Caution, something to watch out for. If there is a CGFI Electrical plug in the wall you notice the "sweating", make sure it is well sealed with silicone. Getting this "sweat" in the plug will short out the CGFI circuit in the garage. It has happened to me, and others I am sure.
