The pool surface, estimated to be 25 years old or possibly older, is in fair to poor overall condition but has a layer of dust obstructing the view of the bottom especially in the deep end + exacerbated by windy conditions also making it hard to see the surface easily. The wear is most noticeable on the shallow end and steps. Some discoloration is visible around the return lines, likely normal during a high chlorine abuse cycle, and the pool has copper plumbing. Plaster surfaces typically last up to 30 years.
Total Potential Cost now $500 to patch shallow end top step to prolong the remaining life of the remaining surface, otherwise I would expect three plastering on the rest of the pool to occur in the next 1 to 10 years = $8-12k+

On the north side of the pool, 5-10 tiles have splits down the center from top to bottom, possibly indicating settling and potential water loss. This is unusual, likely structure-related, and the splitting is spreading from top to bottom. The tiles appear relatively new (less than a few years old), suggesting a prior Band-Aid fix for an underlying issue. Additionally, inside the skimmer throat, between the skimmer and the tile, the mortar is likely too thin and requires re-waterproofing. Repair costs are hard to confirm without exposing the main issue, but a rough estimate is $1,000-$2,000 or more, depending on the problem.
Total Potential Cost: $1,000-$2,000+ (tile and skimmer throat repairs)

Also, I do hear a hollow coping stone around the skimmer. Otherwise some of the coping stones are getting close to that point in the next 10 years expect a cost of around 500 - 2k to reset the loose coping stone around the pools copying and skimmer when needed.

The pool water shows no clear signs of water loss currently, but a recheck is recommended in 1-30 days to confirm. The water has high pH, very high alkalinity, and low chlorine levels, suggesting frequent organic matter entry or growth within the pool. Minor treatments to eliminate organic matter, including phosphates, are recommended, costing $85 and up.
Total Potential Cost: $85+

The pool’s main drain cover is outdated and requires updating for safety, costing $100.

The pool’s skimmer appears fairly new, likely less than 10 years old, and is in solid condition with minimal chlorine wear or abuse. It requires a new float, float O-ring, weighted basket, and skimmer lid, with an estimated cost of $400 for all parts and installation.
Total Potential Cost: $400

The pool’s bottom cleaner, over 10 years old, is likely due for updating or standard maintenance. Maintenance, including new hose segments, tires, and tail, costs less than $205. Alternatively, a new unit would cost $650.
Total Potential Cost: $205-$650 ($205 for maintenance or $650 for a new unit)

The manual fill does function however it does leak when it’s on recommend minor service to resolve this issue which would likely run around 125 to 250

The pool has an old Swimquip-style light with water inside the lens, located less than 10 feet from an older, likely non-bonded junction box. For safety, updating both the junction box and pool light is recommended. A new white LED Pentair pool light costs $900, while a color LED Pentair light costs $1,250. Installation for either light is approximately $350. Because the Swimquip light is a smaller 8-inch style, installing a different light requires additional modification, adding $200 in labor and/or parts. Alternatively, updating the light during a replaster stage with a new light niche would cost an additional $1,000.

The Jandy CL 580 cartridge filter, likely from 2011, is heavily sun-damaged from afternoon sun exposure and is in fair to poor physical condition. Despite this, it has no leaks, and the pressure gauge is relatively new. The filter shows high pressure, indicating the filter elements need servicing, which could cost $150. If the elements require replacement, new ones may cost $550. At that time, consider replacing the tank O-ring for $50. The filter hasn’t been opened in a while, as evidenced by organic matter buildup around the tank band.
Total Potential Cost: $750 ($150 for servicing + $550 for elements + $50 for O-ring)

Filter pump has a new drive on the back, and the motor appears relatively new, about five years old, in good condition. No water loss or leaks present. No air seen inside the pump basket. The only issue is the bonding wire is not connected. Recommend connecting the bonding wire. Estimated cost: $50.

The Pentair 3/4 horsepower booster pump, which is not turning on despite the timer possibly working, is missing its bonding wire, costing ~$50 to fix. An unusual light switch under the timer may be blocking power. The plan is to check the switch, timer, and pump in that order. If the pump needs replacing, a new one costs ~$500, with ~$500 for installation and ~$200 for durable hard plumbing hoses to replace soft ones for longevity.

The pool system lacks a connected bonding wire for the Pentair 3/4 horsepower booster pump, costing $50 to fix. No GFCI breakers or subpanels are present, and installing them with a water bond costs $300-$900. Two timers control the pumps: the left, over 20 years old, likely for the filter pump, and the right, 1-5 years old, for the booster pump. Both timers are missing protective plastic terminal components, costing $20 each ($40 total). Three switches lack covers, costing $20 each ($60 total). The right timer appears to function but shows no gears turning, suggesting it may be faulty, potentially causing the booster pump’s failure. The Unistrut style metal poles have corrosion at the bottom, and the surrounding concrete is breaking. While currently sturdy with no ruptured conduit, the poles are unlikely to remain sturdy beyond another 10 years.
Total Potential Cost: $450-$1,050 ($50 bonding wire + $300-$900 GFCI breakers/subpanel + $40 timer components + $60 switch covers)

The pool equipment is due to have plumbing and equipment covered from UV using a UV mesh. Also, the plumbing is copper and an inch and a quarter section and two 1“ and a quarter returns.
