Sorry to hear you are having problems with these cowboys.
We have had 7 leaks to date even down to ripping out the bath completely and replacing it with a new one at my own cost. I still have not been compensated.
Unfortunately Bryant Homes do not build houses of quality.
They bodge. The sub contractors bodge everything and then Bryant Homes deny everything.
Have a look at my website.

If I can help you in anyway regarding advice on legal issues (as I am now there) then pm or email me.
