I noticed several cracked bricks on the top 3 ft of my
chimney and a couple brick have lost the entire outer face.
A roofer told me that water is penetrating the brick & morter and freezing causing this damage. That makes sense to me, what do you guys think and what should I do??
Is the cement crown just ordinary cement? What is the best
thing to use to seal the brick and crown after I repair it
Thanks in advance for your proffesional advice
