It is good news, considering we've had no headway with the contractor actually doing anything about his shoddy job.
What was it they screwed up anything big? I have been otherwise occupied lately and have not been following much around here in case you already mentioned.
Lots of stuff. Just to take one example, there was the issue of nails. A lot of nails aren't all the way in, with heads several millimetres out, or have to great a distance between them, or, for that matter, that there aren't enough them on some boards and window frames, resulting in the boards twisting and loosening. It's the handiwork itself, but it's also that they've managed to fuck up some of the ventilation, remount drain pipes wrong, forget to seal cables running through the walls...
Of course, there is the isolation itself. It's not doing its job properly because the material they used is not properly sealed against window frames and such.
You name it, we have problems with it.
