Simply, if we screw-up we pay for our mistake and don't try to squirm out of it by making the homeowner jump through hoops. Like most manufacturers, we try to do the very best job we can. A certified testing laboratory checks our product to make sure we meet ASTM F964 - 94, the vinyl fence standard, and performs additional tests that we require and that ASTM doesn't. We are proud of what we do and we are not afraid to have our work checked by testing professionals. We have heard that in the vinyl fence industry, on time, proper deliveries can be a problem, especially in the busiest time of the season.
Any manufacturer has a finite capacity.
The problem with lead times is that they are not specific enough, and can be manipulated by manufacturers. As you wait for your table, you observe other people putting their names on the list. Then a couple walks in. The owner greets them personally and immediately gives them a table. They are regulars, high volume dealers.
