damp in bedroom
There are many reasons that can cause the dampness but more is needed in your question. Is it a problem that just started, or an ongoing problem? Does it happen only when it rains or snows?
Here are some possibilities: When a home is built, there are vapor barriers that have to be installed to prevent moisture from entering the interior. Concrete slab floors require a 6 mil minimum plastic vapor barrier and the exterior walls need tar paper or another type of vapor barrier under the siding. The windows may need to be caulked or replaced.
Check if the grade of the fill adjoining the room slants down toward the structure, it will cause water to accumulate against the structure. Another possibility is inadequate ventilation – are the attic vents open – the house needs that ventilation.
Since you already attempted to waterproof the interior, it seems that the problem is coming from the exterior, so check outside to see if you can find the source. As a temporary fix, you can buy something like DampRid, it’s a product that absorbs moisture – I use them in my boat. You can also buy a dehumidifier for a temporary fix, but you really need to find the source because you don’t want to end up with a mold problem. I hope this helps some.
