Did my first break in burn last week and the next day I decided to check the firebox to check for damage. I noticed that three of the four corner joints had extra cement in them but the fourth did not. I didn't check deep into the joint to see if there was cement deep inside or not but thought I would send Woodstock an email to see what their thoughts were. A quick response from them advising that this was normal but for peace of mind they were sending me a tube of cement to repair the joint. Very pleased!
