Expansion gap or a problem?

Hi, I’m a new pool owner (bought an house with a pool) and wondering if the approximately finger width gap between the pool tile and the pool decking is a problem?

It looks like it runs all around the pool with varying widths. If this is a problem, I’m not sure if I need to call a pool decking company to help fix or if this is something I can fix myself with some caulking???

The pool was built in the late 70s and is about 20k gallons.

I’ve attached some pics of the issue. IMG_3336.jpeg

Any help appreciated! Thank you.

Its likely that the opposite side of the decking has sunk a bit which opens up a gap there. You can get a slab-jacking to raise it back up or lift it with a jack and backfill it. But like said, dont let much water get in the joint.

thanks! It does look like the slab sunk and opened up that gap. I’ll take a look at slab jacking to correct that.

Is it worth trying to DIY and fill in with some closed foam then caulk the gap or is this more of a professionals only project?

We are also looking into new decking, but hoping to wait 1-2 years for that project. So hoping to find an inexpensive fix that can last that long.
