Hi everyone! I am new here - bought a 1970s colonial back in June that needs a total overhaul.\n\nI have a question on sheetrock repair/replacement. Long story short - I can see where every seam and nail patch was done in a couple of the rooms and it drives me a bit crazy. My question is is this an issue that is worth the hassle trying to fix (the likelihood I will be able to get it flat (especially the seams) or if it's just better to pull it all down and start over. I am pretty good at finishing new sheetrock installations but have never attempted to repair bad seams etc. on this scale.\n\nThanks in advance!
