Horrible job! The seam lines in our kitchen and dining room of our custom home we are building are highly visible as well as the tape lines in our garage. Their first reason for the lines was that our Trusses had shifted which caused settling and made the lines visible. Mind you the trusses run North and South and the seam lines are running East and West. We have sanded down a few areas and they have way too much mud on the seams. They are trying to include this in warranty work and expected us to wait a year for them to come back and fix the problem. We have not even moved into our home yet. We have been fighting with them for months. Garage lines show that there is not enough mud on the tape since you can see the actual end to the tape. Their claim is that since it is a level 4 finish you will see all the imperfections if you use any type of gloss paint. We wanted to be able to wipe down walls even in the garage as our home is in the country. Praying they make the job right.
