Pool Surface
The surface is plaster. It is in overall fair condition. There’s minor wear present throughout, mostly seen on the edges and in the shallow end. Still, it is present throughout. The surface is approximately 10 to 15 years old, looking closer to 15 to 20. This can be caused by high levels of chlorine over prolonged periods of time. The wear present is low points and luckily there are no edge step chips, just normal wear for its age. Plaster typically lasts 20 to 30 years and appears to be on the last 50% of its life cycle.
In the shallow end I do see some scratches on the south east side of the shallow end, but still no major issues. The only blemish I notice of potential concern is on the southwest corner of the step entry steps on the north side of the steps. Below it there is a small rust colored stain that appears to be coming through this corner of the surface. Normally I would likely classify this as just simply a surface stain, but at its location it may be rebar related. Recommend minor treatment to confirm at around $100 to see if this is just a surface stain that can be removed or if it is in fact coming through the plaster surface. If it is coming through the plaster surface, the cost on a rebar stain repair like this would range between $500 to $1,000 and up depending on what the issue is underneath, but again I feel it is 90% or higher just a surface stain.
Cost summary (this section only)
• Minor rust stain treatment and testing: ~$100
• Rebar stain repair (if confirmed): $500–$1,000+
• No other immediate costs required

Waterline Tile
The waterline tile is all in like new condition without issues present on the north section of the pool. There is some a raised wall likely 12 inches that does have rock on the front of it. It appears to be in relatively good condition. No gaps in the mortar present, no issues to address at this time.
The only area of potential concern is on the raised walls concrete platform step. It does appear that it is settling slightly and mastic has been used in between the rock and the concrete to fill in this gap that is forming. In general this is common, especially with landscape areas that are settling naturally overtime. While it is likely not required right now, it may be in the next 5 to 10 years to have this area mastic and sealed again if desired. That might cost around $500 to $1,000 depending on gap size.
Around the rest of the pool there are some small separations occurring that mastic can be used if desired for aesthetics and this will likely also need to be redone in the next 5 to 10 years, likely not any sooner. It does appear that this pool has a potential overfill port on the south east side of the tile border and it is out of level where water typically won’t go up above and ingress into between the concrete and the tile if this pipe is clean and well kept.
Where the skimmer meets the tile it does appear that it is an original skimmer and may need to be waterproofed soon in the next five years, most likely. Resealing that may only cost $100-$500 or less.
Cost summary (this section only)
• Future mastic and sealing (raised wall / separations): $500–$1,000 (in 5–10 years)
• Skimmer-to-tile waterproofing / resealing: $100–$500 (in next 5 years)

Water Quality
The water quality as far as clarity is concerned it is clear. However, the water results show that the chlorine level is very very high, above 20. pH and alkalinity are also elevated, but the main concern is the highest CYA level. Currently it is above 150, possibly over 200. This is likely due to using chlorine tablets as a main source of chlorination.
Additionally, there is what appears to be algae present in shaded areas even with a high level of chlorine like this. This is typically a sign that algae will be hiding and when chlorine levels come down to a reasonable level, the algae will proliferate more extensively.
Therefore recommend adjustments to water chemistry, which may just simply include a 1/3 or a half drain and refill. At that time algae treatments will be required. A 1/3 or a half drain may run $200-$300 to pay somebody to do it, while the algae treatments will likely cost $100-$300 to perform depending on severity.
Also note that due to the high levels of chlorine, it is skewing the results and may require recheck in one to 30 days to confirm status.
Cost summary (this section only)
• 1/3 or half drain: $200–$300
• Algae treatments: $100–$300
• Water chemistry adjustments and recheck: included above

Main Drain
The main drain has a channel drain installed which likely was updated at the last replaster stage. It does appear that this channel drain is older than seven years and should be updated for safety, especially because this pool is likely around 6 feet deep so the chance that someone will be standing on it is pretty great. The cost of a new cover is around $200 and someone will probably charge around $100 to $200 to install it.
Cost summary (this section only)
• New channel drain cover + install: $300–$400

Skimmer
The skimmer appears to be the original and in working condition at this time. I don’t see too much significant organic matter presence. I’m sorry chlorine staining present, but the skimmer has many stains present likely from high chlorine and scratches and marks. It’s only one that is concerning me at the very bottom of the skimmer itself. Note that when skimmers get older, they begin to get brittle and can crack and rupture and caused water loss. Still in the meantime, it may be wise to consider updating the skimmer at the next replaster stage if it is the original skimmer and wasn’t updated in the past 13 years, which at time of replastering may cost $1,000 to $2,000. But for now recommend updating the float, float O-ring and skimmer lid likely for less than $200 installed.
Cost summary (this section only)
• Float, float O-ring, and skimmer lid update: <$200
• Full skimmer replacement at replaster (if original): $1,000–$2,000

Bottom Cleaner
The bottom cleaner itself appears to have some parts updated, including swivels and a cover, but it does appear that the bottom cleaner itself is likely older than five years and in relatively poor condition. Its hose swivels are all showing signs of heavy chlorine abuse, and in general, I feel confident that it will likely need $100-$300 in repairs which may just tend you to recommend changing the cleaner to a new unit versus updating this one once it expires.
Currently it is working well without any major issues. Its front right tire is skipping slightly indicating the band inside is due for update and/or service and there’s at least $100-$300 in parts to update on this unit currently which will include likely just new hose and swivels and tires soon and tail soon.
Cost summary (this section only)
• Hose, swivels, tires, tail, and service: $100–$300
• Future full replacement recommended once it expires (not estimated)

Pool Light
The pool light present is original. It is older. It is recessed back into the wall slightly, which is not necessarily the best for light distribution, but is likely no major issue. Still, the light can appears to have water present inside the light lens condensation, and therefore the light can should be updated for safety. You can is less than $300-$1,200 depending on options. You’ll pay someone around $400 to install it.
Cost summary (this section only)
• New light can + install: $700–$1,600 (depending on options)

Like model light is $700 + install $400

Filter
The filter is likely small for this size pool. It is 150 ft² which isn’t terrible. It’s just at the low end of sizing. This filter is older, likely 15 to 20 years old. The pressure gauge is indicating 22 psi even though the pump is at high speed, but generally indicates that the element inside is due to be updated. A new element on this size filter is right around $300-$400. Installation and service may run around $150 and I would recommend also updating the pressure gauge to a liquid filled at around $50 as this gauge is likely original.
Cost summary (this section only)
• New filter element: $300–$400
• Service and installation: ~$150
• New liquid-filled pressure gauge: ~$50

Filter Pump
The filter pump wet end is likely original from the original installation of the pool, which is likely over 25 to 30 years old, with a new motor. The motor is a variable speed with essentially two speed options. The motor does not have its bonding wire connected. Recommend connecting it for less than $100.
It does not appear to have any water loss issues at this time. It would likely be wise to consider updating the wet end in the next 1 to 10 years if issues develop. It appears that the seal between the pump pot and the volute area is leaking. This is what I expected as this is a very old plastic housing and it would be wise to just consider updating the entire wet end for around $200 to $300 in parts plus around $500 in labor roughly. There are additional options but that’s just a generic option using the existing motor which is a good motor.
But it may be beneficial and wiser to just consider updating the entire pump complete with a SuperFlo VS which is a $1,100 pump, maybe $1,200. This may be a better option with more functionality and would allow you to get away from this timer and instead use the onboard timer of the pump itself. A secondary even better option would be the Pentair I 3 1.5 as it does allow Wi-Fi Bluetooth connectivity and if kept out of the sun should last 30 years or more.
Also note that any of the new pump options would require installation charges of around $850.
Cost summary (this section only)
• Bonding wire connection: <$100
• Wet end replacement (parts + labor): ~$700–$800
• New SuperFlo VS pump + install: ~$1,950–$2,050
• New Pentair IntelliFlo i3 1.5 pump + install: higher cost (recommended)

Board and Timer
The board and timer has at least the timer itself updated recently. It appears to be in working condition. The timer box could just use a simple spray painting to help protect it from rust at around $50 or less.
It does not appear that the variable speed pump has a variable speed Siemens breaker. It is around $100 parts cost, but it does have a GFCI for the pool light located to the east of the pool next to the fence. Still, it would be wise to consider adding a GFCI for the pool equipment and or pool pump at around $100 parts and then an electrician may charge around $100-$200 to install it.
Cost summary (this section only)
• Spray paint timer box: ~$50 or less
• Variable speed Siemens breaker: ~$100 (parts)
• GFCI for pool equipment/pump + electrician: $200–$300

Valves and Fittings
The pool equipment pad is not covered from the sun using UV mesh. It is in the sun the large majority of the day. Recommend covering from the sun using UV mesh for less than $50, throwing it over like a blanket.
Additionally it would be ideal to repaint and re-label the equipment pad for longevity at around $200 or less.
Also there appears to be a leak on the return for the bottom cleaner. This valve may require replacement due to age and condition and if so, a cost of around $300.
Cost summary (this section only)
• UV mesh cover: <$50
• Repaint and re-label equipment pad: ~$200 or less
• Bottom cleaner return valve replacement: ~$300
