A quick question... With a new liner installation, I also need to replace the coping as some of the original coping is broken and missing. The guy who is installing the liner was going to replace the coping with a vertical plastic coping and include it in the price of the liner replacement. I questioned whether using a plastic coping was a good idea and he said he uses the plastic coping in most of his liner installs and has had no issues with it failing over the years. He said it will be an additional $200 dollars to instead install aluminum coping.
My question is, for the low cost of $200 dollars is it worth installing aluminum coping or will plastic last for years to come.
Thanks in advance for opinions on this.
