These jobs are with the same GC and the same property/owners. The first job had a set amount which was filed with the original 20 day notice. The second job we ended up getting was much more money so I filed another 20 day notice with that new amount. When we received final payment on the first job I tried to file a final payment waiver and the GC told me since we weren't finished working on the house it was still a progress payment. We may be starting a 3rd contract with this GC and I am curious if I should be sending these new 20 day notices or not.
