Carolina Building Group built my sunroom with life time warranty. What a joke! The room was not built well at all. All doors leak. Fan blades turn down and the fan itself looks awful. The weather has damaged the way it looks. Concrete added out side the room has cracked and room has become an embarrassment. I have tried on several times to contact company with problems but have not been able to reach them by phone or letter. I had to pay for the roof replacement that our insurance company said was causing a leak in the adjoining room. Ignored by Carolina Building Group when I contacted them about this. Very disappointed.
