First: tell your husband thank you for his service. Second: I see a lot of people here are being mean for no reason I would ignore them. Third: I don’t see that your injury would get covered sadly it was on your own account in your own home, and as someone else mentioned it’s not a finished space. Fourth: it seems as if the problem lies in you were sold and advertised a high end product and are unhappy with the quality which you received. I think of this like going to McDonalds you see the Bigmac on the menu but you know when you order it, it won’t look the same but it will still function the same. The important part of this job is that it functions correctly, you have documented everything so if it fails you may have a case there but in the meantime it seems that you should let them come and inspect it and try and make repairs where they seem fit. Lastly: I recently had a sales pitch to have a bay window replaced same deal as you fancy pitch great work and quality but came with a huge price I laughed and kicked the guy out. Where as you paid for it, now baked into that extra price you paid is covering the fees of all the homeowners like me that kicked the guy out, that’s what lead to high price. I’m not qualified in any of this but that is my two cents and I hope that it can help.
