Centex (and sub-contractors) spent the entire day working on various problems with our new house. They ended up pulling up carpet, cutting holes in the floorboards, rehanging a door, and re-installing the kitchen sink garbage disposal. Quite a day. They will be back at least tomorrow and Monday.
Warranties are great. While I was remediating the mold in our old house, I got so sick of house projects. I'm so glad to have someone else do the work. I can finally say, 'It's your problem, not mine.'
