I loved my three season room which added great space and was very well built. However, the sliding door screens have rollers that keep breaking. They are a very unusual design apparently. We waited several days to have someone come see after four of the rollers broke. Then waited several weeks for one door to be fixed. The other two doors are breaking now too and this is after less than one year.
I am tired of waiting the days and days to have someone come to see, then wait some more while they order parts, then wait some more for them to schedule someone to put the parts in, then wait some more because the door had to be taken to their shop.
