Windows & Door fitting

Leaking windows replaced. Left with wet concrete smell in concrete block below.

Anonymous user 15/03/2024 - 2.49 PM

I had a window that leaked water into the concrete structure below (block). The window was replaced but the smell of wet concrete persist in the bedroom. I tore out the drywall and ran a dehumidifier and rechecked for leaks. The area is bone dry, but the smell of wet concrete (musty smell like basement) won’t go away. I tried cleaning the area but nothing seems to work. I appreciate some advice on how to get rid of the smell. A reply to Stephen Smith. There is no wood below. Only the cement floor. I tore out the all wood and drywall around it, and any other wood just in case. It’s window, cement block and cement floor. The leak has been fixed for several months and no water has entered the area. Is it possible the cement block is still wet on the inside where I can’t see it? How can I dry cement block?

Are you a tradesperson and able to answer this question?

If there is a suspended wooden floor below the window it is possible that the smell is coming from wet or dry rot in the timbers. Lift floor coverings to check. Concrete rarely smells once it has dried. Have you taken any moisture readings from the wall and floor? If the floor slab is quite thick or has no damp proof membrane underneath, it then it can be slow to dry. I would continue with the dehumidifier and invest in a damp meter so you can check the drying. Please come back to me if you have any more questions.

It is hard to say without seeing the area but concrete and masonry take a long time to dry out.If there is no other source of damp or leaks then it must need to dry further especially if there is concrete below the blockwork

Since you have exposed the block work, I would paint the wall with tanking slurry and then insulate and dry line. If it still smells there must be damp somewhere else.
