The pool surface is a plaster surface. It appears to be fairly worn, likely worn 90 to nearly 100% through, nearing the gunite, and in some sections of the middle and deep end of the pool, it is nearly due for replastering. Replastering a pool this size would cost 8 to 12,000. Signs that replastering is required include water loss, which may be present as upon arrival the water level was low and had to be filled for approximately an hour and a half. This could be a sign of water loss. I found a crack on the west northwest side of the pool that runs all the way up, which will likely require approximately $2,000 in extra repairs at the plaster stage. On top of that, the other blemish by the pool light (pool light canister is wearing out of the wall - likely water loss here) may cost up to $2,000 to repair as well.
Estimated total for this section: $12,000 to $16,000.

The pool tile is all present with no loose or missing pieces. It is older tile but overall in good condition. The only area of issue is inside the skimmer throat or around the skimmer. This will need to be corrected at around $1000. The raised rock waterfalls and raised rock around the pool border appear to have many sections where it’s becoming loose and no longer watertight on the waterfall. I would estimate around $2,000 to $3,000 to refill in all the missing mortar joints and to ensure that these rocks do not become loose, especially when people are standing on them or jumping off them. Note also it does appear that these rocks have had a shiny clearcoat put over the top of them almost like a sealer. This is in fair condition now but may eventually require removal via glass bead blasting, which likely would cost around $1,500 for that service, which is not needed at this time.
Estimated total for this section: $3,000 to $4,000.

Recommend recheck water chemistry in 1 to 30 days to confirm water loss results - but as it stands now, water loss does not appear to be obvious, recommend adjusting pH in alkalinity as well as CYA levels ($100+).

The main drain cover is older and due to be updated for safety at around $200 or less to install, or simply wait for the plastering stage to install an in-floor channel drain, which is much better at around $1,000, and if you did the channel drain, this would be a compliant VGBA cover.
Estimated total for this section: $200 to $1,000.

The skimmer is missing its float and float O-ring as well as weir door and skimmer lid. I’d recommend updating all of those for less than $300 installed and maybe even a weighted basket for another $50 compared to this basket just personal preference.
Estimated total for this section: Less than $250.

The bottom cleaner appears to be a newer unit on an older hose, unsure as to why the mismatch, but overall the unit appears to only need a new tail soon ($105 installed or less).

The pool is equipped with a manual fill only. It would be wise to consider adding a $100 float that can attach to a garden hose to allow for automatic filling. Additionally, the manual valve on the house appears to be leaking from its seal which will require service. I’m estimating both are needed for less than $250 total.
Estimated total for this section: Less than $250.

The pool light does not turn on at this time, but it wouldn’t matter because it’s filled with water and condensation inside the light lens. Recommend replacement for safety. It appears to be a standard 10 inch incandescent light can. The pool light cost for a white LED Pentair light would be around $950 plus installation of $350.
Estimated total for this section: $1,300.

Due for service ($150) and possibly element updated ($500). Also a new pressure gauge ($50) and likely band ($300) soon. Or I’d recommend a Ta-100d Pentiar Sand filter as a much better option vs any repairs.

Single Speed Wet End / Variable Add On Motor. Working without issue.

It appears that the board timer is not connected to a GFCI for the variable speed pool pump and one should be installed for safety and at the same time update the GFI or GFCI for the pool light for safety. I would estimate this for less than $300 in parts and likely less than $300 for an electrician to install all of this.
Estimated total for this section: Less than $600.

Recommend painting, labeling and covering the equipment pad from UV ($300+). Otherwise ideal.
