Sorry for the slow reply.
We had a number of defects and also a number of further defects caused by tradesman who dropped gloss on the carpets, LVT etc that we are still having to argue about 5 months later.. We're still waiting on the defects we reported in November of last year to be rectified.
We did get back a professional snagging survey today which is 6 months in but more to protect us. He highlights the expansion joints and they aren't properly filled as well (image attached). Also the main ridge beam in the loft being green and mouldy, site said it's nothing would you agree? Also the extractor going into loft stops just above the insulation, the housebuilder said it recirculates so isn't required to be attached to anything.
Lastly one of our biggest frustrations is the mastic finish on the house is poor. They did our back door again yet 2 months on is falling off and pulling plaster in the walls, yet I have been told it's movement they won't fix it again. Also they fixed the mastic on the stringer but only in areas so have two different colour lines and still falling off in areas and junctions as you can see in the picture really poor. and have gone pink.
Any advice would be greatly appreciated.
