Hello everyone, thanks in advance for your help. Here’s my story. A tree limb fell on the second story deck knocking off three sections of railing but worst of all knocked loose the 4×4 posts supporting them. I have to cut back the deck to resecure the posts but the deck is coated with fiberglass. Is it as simple as cutting it back with a circular saw then patching the fiberglass with a fiberglass kit or is it time to crash and burn. There’s no access from underneath without a tremendous amount for disassembely.Thanks again.
