The surface appears to be between 7 and 15 + years old, some wear seen throughout (50% of surface).

I can see one clear issue on the deep end step face and top as it appears it is some type of delamination horizontal crack that only appears to run approximately 12 inches. This may be surface level only (vs structural) but to repair this either way expect a cost $1k+ for surface or $3k+ for structural. Can be confirmed once opened - if confirmed losing water - which it likely is not a water loser (as calcium is coming through it).

Overall my immediate opinion is the surface looks ideal for its age. Likely re plastered in the past 15 years or less, with remaining life left, sure some blemishes are present but often common with plaster pools over time.

There is calcium present, appears to be older and can be removed likely at a cost of $700 or more. Versus re tiling might be a cost of $1500 to 2500.

Around the pool, the concrete is in relatively good condition except for the north east side, the concrete is settling and lifting, it appears to have been filled in previously with mastic, which it may be due soon ($1k+) but what would be more ideal is to attempt to level the concrete (concrete jacking) out and then mastic ($1500+)

Additionally, some of the southside concrete has moved, and there is several trip hazards present that should be grinded and or filled with mastic ($1k+).

The water chemistry is nearly ideal, there is a perfect level of chlorine with algae present, which is generally an indicator that phosphates are present and will need to be removed with treatments ($275+).

The main drain cover appears to have been updated to a VGBA compliant cover.

The skimmer, appears to have been heavily chlorine worn, and has some buildup at the waterline, that I initially thought was a cracking skimmer, but it does not appear to be an instead is buildup. I would recommend updating the float floating weir and skimmer lid as well as a weighed basket for preference / longevity soon ($500+).

Recommend a tail sponge and maybe a new tail soon ($105 or less)

The valve is leaking during use, recommend updating as the valve may be leaking even when off ($250+).

The pool light is no longer functioning. A new light can is around $750 for a Pentair high-quality - vs a low-cost option is an Amazon $200 light can new + install $400.

The filter pressure may be slightly high and nearing its quarterly filter cleaning due date ($150) but it will also need a new pressure gauge ($50). Recommend service to confirm the elements ($500) remaining life.

Older. Working without issue. Recommend re attaching the bonding wire for safety.

The timer box / board is in poor distressed condition, and will eventually in the next one to 10 years need to be updated ($350+ install), but would be a wiser investment would be to consider, a variable speed pump with a built-in timer, and you would take that 350 and instead install new variable speed breakers and a subpanel box here for the highest level of safety (approx $650 total with electrician fee + $350 in parts).

Otherwise, all that is needed right this moment is a protective cover over the time terminals ($50) to prevent electrocution / shock.

Working without issue, still just to repaint relay and cover from UV would be best ($200+).
