NONE! We had Aluminum Company install vinyl siding, bay and bow windows, gutters and gutter helmets on our home years ago. It looks as good today as the day the work was done. The work Aluminum Company recently didfor us was actually the replacement of 2 windows that another company installed for us prior to Aluminum Companydoing the aforementioned aluminum siding, windows and gutters. We used another company to initially install these2 windows because of a "cheaper price". I am now a believer in the adage that "the bitterness of poor quality remains long after the sweetness of low price is forgotten". - Oct 05, 2014 in Raleigh, NC
