Looks like I will be removing the new replacement windows that a hack installed for me last year. This was the worst job I have ever seen, this guy claims to have been doing carpentry for 40 years! I would not be surprised if I find that the only thing holding the windows in is the caulk. Anyway, my question is: What is the easiest way to cut caulk, remember this is about 4" thick. I know I will run a sawsall to cut any screws that he may have put in by accident. TIA
