I've been installing decking for 25 years. Most people want composite on the floor and top cap of the rail. The rest, railing and fascia is usually wood, with aluminum spindles.
I've had a composite deck on my house for 8 years, all we need to do is clean the floor, with olympic deck cleaner, spay on, hose off, no scrubbing.
The rails are finished with sherwyn williams solid color stain, which need to be done every 4 years.
