Hi,
I have a 50 year old home with a pinkish brick veneer. I have lived there about 10 years. There is one side of the house which faces south with an area approx 40 feet tall by 20 feet wide the interior side of which is the chimney. There has never been a problem with it but this year for some reason there is an extensive area of effervescence to the middle of this span. The house is in Connecticut and it has been a wet and snowy winter.
My question is, is it normal for this to show on brick that is so old (and in good condition) verses new construction?
Secondly, might the old homeowners sealed the brick from time to time and I haven't so that is why it is happening?
Thanks much!! Steve
