Found moisture! What to do?

[saraparara]

Had a suspicion it was like this...
Going to lay a new floor and removed the moldings and tore a bit of the vinyl flooring and found moisture in one corner.

Have no idea where it's coming from!?! Seems to be limited to this corner. And even less of an idea of what to do about it??

Can anyone help...?

Could it be that it came in through the door? maybe a rather limited problem then.

Report it to your insurance company.

I'm so tired! Recently had an inspector at home to check a leak in the bathroom.. :/
Should have known about this back then too!

I would guess that it's leaking in at the window or door. I had a similar experience, and the entire sill was rotten. A little water had seeped in through a gap in the window frame when it rained against the window.

Hard to say based on just these pictures, but the leakage is probably from an installation error with the window-door combination. Perhaps a metal flashing or a cover on the outside has been misaligned or installed incorrectly. Sometimes water seeps in the most unusual ways when the wind is strong. What's outside the door, a balcony or a patio? Is there metal under the decking? Could there be standing water under the decking? The damage is already done, so it's important to quickly find the cause to prevent it from getting worse.

Hmm. It looks like a balcony door. Under the decking, there's likely folded metal that goes up and into the facade. The phenomenon is probably because it wasn't originally intended to have a balcony, just a metal roof. When you add decking or similar, it prevents snow from running off. Rainwater stays in the decking and seeps in, etc. You'll probably need to remove the door, plus a bit more underneath, and check the ceiling on the floor below to see how much moisture has seeped down there. If you bought the house within 10 years and also had it inspected, you can likely claim a hidden defect.

now it has rained half the night so I thought I would see something more where it might be coming from... but no! now it's dry. There's a balcony outside, a patio roof underneath but it can't hold water underneath.

however, the gutter (or rather the board the gutter is attached to) isn't fastened properly so some water drips down and splashes.... but then it should have gotten wet now when it's raining..

going crazy!

talked to the insurance company and if the problem came from outside, it is not covered by the insurance. :/

Post pictures from the outside so they can be checked, preferably detailed photos of the plåtarna.
