Hi all,
Can someone tell me the best way to eliminate cold air coming in from all 3 sides (the top and 2 sides)of my masonry fireplace where it meets the wall. The cold air is coming in where the mantel and the 2 brick sides of the fireplace meet the wall. I removed the mantel so that I could get a good look at everything and I found that the cold air is coming from several areas, basically anywhere there is a slight opening, i.e. where brick meets wall, through mortor holes in bricks, where mortor is cracked etc. On the 2 sides it coming is where the brick meets the wall. My thoughts were to just caulk the sides and the top, but now I'm wondering if that is going to be good enough. Should I stick some insulation into the cracks instead of caulking or should I do both or is just caulking all that is needed. Or should I be doing something entirely difffernt. I like the fix problems the right way the first time. Any advice is appreciated.
Thank you

Maybe try some of the "Great Stuff" expanding foam. If it is just a crack maybe open the crack with a 1/4" drill bit. Insert tube of the can and go to town. You might want to get the window and door type so you done burst the wall. ;)
