Pool was installed 5-7 years ago. The deck is not flat. There are a series of steps leading to the deep end which is the highest point. I noticed a 1/2” gap last night between the tile and concrete. How to fix? We do have redwoods but they are about 15’ from the pool. I just got the house about 7 months ago so I’m new to this.
Pool deck lifting?

Welcome to TFP.
Depends if the entire slab is lifting or if the other side has sunk causing that area to lift.
Put a level on various areas of the slab and see how it is tilted.
You can raise sunk areas by mudjacking. If expansive soil or tree roots have lifted a slab you would need to demo the slab and rebuild the deck. Or you can fill the gap with some type of foam and flexible sealant.

X2 above. The slab should have about 1/4 inch per foot of slope away from the pool. If it’s more than that, then the back may have sunk, which lifts the front.
I went around the entire slab (at least 20
Measurements in various places) with a level including the parts that did not have a gap and all of the measurements were between -1 an 2 degrees. It seems like the “caulk” and whatever is behind it is degrading. My son (who swims in the pool frequently) later told me that it has been this way for many, many seasons but his dad did not want to fix it. In summary, it does not seem to be sinking or lifting. How should I fill that gap? I understand that water getting in there is not good.

There is no easy way to fill that large of a vertical gap with "caulk".
It has been that way for years and I think if you leave it alone it will be fine for many more years.

Got a quote today. He said he could fill in the larger gaps with concrete or foam and the smaller gaps with silicone for $650. Since I’m new to this, is this something I can do on my own, let it go, or cough up the $650
