We have solid brick walls throughout the house and certain parts of the walls are bubbled looking like rising damp.We have copper pipes inside the walls and I was wondering if these can sweat and cause the bubbling on the plaster. We have gone into the wall to investigate but cannot find a leak. What we wish to do is find a solution to get rid of the bubbling and stop it returning. We would really appreciate some knowledgeable advice. Many Thanks

Copper pipes inside a brick wall can sweat if air can get to them. It is the moisture in the air condensing on the cold pipe.

The wall could be bubbling because the right paint was not use to paint them, that is if they are painted at all.

There is a meter that you could use to measure the moisture in your brick in these places that are going bad.

You may could borrow one from a , plumber, painter, carpet layer, tile man, and others just to give you an idea if you might have a friend that had one.

As far as a leak you could do a shut in at the meter if you have one, turn off all water using appliances in the house and watch the meter for an hour or so and it will show you if there is a leak

Is this painted brick, block or stucco covered block or something else?

Is the brick on the outside surface or inside the house?
