I had my pool built 2 years ago. While resealing the deck, I noticed that on one side of the pool, the contractor did not put an expansion joint. The concrete slab is touching the coping and there is no room to put a joint. So far I do not have any crack on the slab, but I am concern about cracking the pool itself.
Shall I cut an expansion joint now or if after 2 years I haven't any issues, it should be ok.
I live in Florida so we don't get extreme cold. Lowest 32F.

Thanks.
