Pool Surface
The plaster surface is in good overall condition and is likely around 15 years old. It shows consistent wear for its age with no major blemishes. It appears to be a replaster job applied over an older plaster layer, with some remnants of the original visible.
There are stains throughout — likely from 3-inch chlorine cookies sitting on the surface for prolonged periods — along with regular wear. At least 15 different spots show this staining.
Rust-colored stains are present: one in the shallow end, one in the middle end, and two in the deep end. These look like potential rebar-related stains.
The remaining plaster potentially has 5–15 more years of life. However, the surface is more abrasive with wear present throughout, which allows organic matter to grow more easily. Organic matter is already growing as a result of the worn surface.
These areas will likely require around $1,000 extra on top of any replastering cost to repair if you decide to replaster. However, full replastering is not needed at this time. Instead, the noticeable rebar issue (especially in the middle end) should be addressed sooner rather than later.
Repairing one or two specific spots by cutting out, patching with an 18-inch overlap, and resealing would cost $1,500–$2,500. The repair will be noticeable and may not blend in perfectly, which is why replastering the entire surface at that time is often the better choice. This is not an urgent emergency, but the longer you wait, the more it will degrade the connected rebar structure.
Cost summary (this section only)
• Spot rebar-related repairs (1–2 areas): $1,500–$2,500
• Full replaster (if pursued later): $10,000–$14,000 (estimated for this size) + ~$1,000 for any rebar fixes during the job

Waterline Tile and Attached Rock Work
The waterline tile, especially on the south side of the pool, is in relatively good condition. No major missing portions of mortar are present — just normal wear for its age.
The skimmer connection and throat also look recently updated (likely within the past five years) and appear to be in good shape overall, even though the skimmer itself is older and shows signs of previous abuse. The skimmer is likely original to the pool.
It appears there was some original tile with decorative rock placed on top, or it could be all original rock and light blue tile. However, the tile from the middle to the south side (approximately 75 linear feet) has been updated to a dark blue color and is in good condition. This update was likely done around 2006.
The north-side rock work is older, but the mortar doesn’t appear to be gapping too much and is in fair condition. It will need attention in the next 1–10 years, specifically the waterline rock (versus the outside rock), as small gaps are forming. Estimated cost to re-mortar the rock when due: $500–$1,500.
It may be a good time to consider removing the rock and updating the tile at the next replaster stage if desired. That work might run $3,000–$5,000.
Cost summary (this section only)
• Re-mortar rock work (when due): $500–$1,500
• Rock removal + new tile at replaster (optional): $3,000–$5,000
Let me know the next section when you’re ready.

There is a light calcium buildup layer that can be removed at desired at approximately $555 or more.

Water Quality
Water quality is fair to damaged overall. Water bugs are present, free chlorine is too low, and both cyanuric acid and calcium hardness levels are low. This indicates the water is likely new or recently refilled freshwater.
I would anticipate approximately $200 in chemicals to balance the water, which will include raising cyanuric acid, calcium hardness, and chlorine levels.
Additional treatments will also be needed to help remove the algae present. This will include phosphate removers, enzyme treatments, and service, likely costing $200–$300.
Cost summary (this section only)
• Basic chemical balancing (CYA, calcium hardness, chlorine): ~$200
• Algae/organic treatments (phosphate removers, enzymes, service): $200–$300
Total estimated: $400–$500

Main Drain
There is one main drain cover in the pool. It is older (likely 20+ years) and due for update for safety.
The cover itself can be replaced for around $100 installed. However, this would not make it fully VGBA compliant.
At the time of replastering, update the main drain itself. This would add approximately $500–$1,000 extra to the replaster cost. Ideally install a channel drain instead of the current split drain for better performance and easier bottom cleaner operation.
A simple STX retro cover replacement would cost around $150 installed, while a low-cost replacement cover would be around $100 installed.
Cost summary (this section only)
• New main drain cover (now): ~$100–$150 installed

• Main drain upgrade to channel drain (at replaster): $500–$1,000 extra

Skimmer
The skimmer is likely original to the pool (2006 or earlier).
It shows heavy chlorine abuse — very dark and brown in color.
It is due for component updates: new float, float O-ring, weir door, skimmer lid, and ideally a new weighted basket.
Estimated cost for all parts and installation: around $500.
Cost summary (this section only)
• Skimmer components (float, O-ring, weir door, lid, weighted basket) installed: ~$500

Also note at this time I’m not seeing very much flow in the skimmer when the pump turns on less than 10 to 25% flow, it seems.

Bottom Cleaner
The bottom cleaner is about three years old (maybe a little less).
It is likely due for standard service, including at least one new tire, a new tail, potentially new hose segments and swivels, and some minor adjustments (the front wheel is noticeably out of alignment).
Once repaired, it should be in perfect working order for at least another 5 to 10 years.
Cost summary (this section only)
• Standard service and parts (tires, tail, hoses, swivels, alignment): not separately estimated (typically $150–$300 depending on what is needed)

Manual Fill
There is no auto fill present. The manual fill appears to be original and is not in working condition.
It will likely require repair around $250 or more to reactivate, assuming the fill line is still intact.
A simpler and potentially better option is to use a hose with an auto-fill mechanism from Amazon ($50–$100). This would provide automatic filling instead of purely manual operation.
A wireless auto fill system would cost around $750.
Cost summary (this section only)
• Manual fill repair: ~$250 or more
• Hose + basic auto-fill mechanism (Amazon): $50–$100
• Wireless auto fill system: ~$750

Pool Light
The pool light is definitely older than 20 years. It has condensation inside the lens and is a 10-inch light can.
It can be updated with the following options:
• Standard incandescent light can: ~$500
• 12V light: $300–$700 or more
• Top-of-the-line Pentair Architectural Series: ~$1,200
Installation by a professional will add around $400 regardless of the model chosen.
Cost summary (this section only)
• Incandescent replacement + install: ~$900
• 12V replacement + install: $700–$1,100
• Pentair Architectural Series + install: ~$1,600

Filter
The filter is a Hayward Clean & Clear Plus (likely model 420), almost 20 years old.
It could not be fully tested because the filter pump was not pumping water at the time of inspection.
The filter elements inside are likely due for replacement ($300–$500 depending on whether you choose low-cost Amazon or OEM versions).
I recommend a new pressure gauge, a new tank O-ring set, and new elements. With service, this would likely run around $750 or less to bring the filter back to near-perfect working order.
Alternatively, consider replacing the entire filter with a Pentair TA 100 D sand filter to avoid the ongoing cost and hassle of replacing cartridge elements in the future.
Cost summary (this section only)
• Elements + O-ring set + gauge + service: ~$750 or less
• Full replacement with Pentair TA 100 D (recommended long-term): not estimated here (typically $1,500–$2,500 installed)

Filter Pump
The filter pump has a slightly older (likely 20-year-old) WhisperFlo wet end with a newer variable-speed motor by Neptune (likely less than two years old).
It appears to be in working order overall, though it is hard to tell if there is a leak at the seal plate due to heavy foliage underneath the pump.
Upon arrival, the pump basket was 100% full of compacted debris, blocking flow so the pump was not moving any water. Recommend service to clean the basket (less than $50 including retesting).
I was unable to fully test the filter pump or filter as a result. The motor itself is relatively new and seems to be in good working condition.
The only other issue is that the electrical connection needs to be properly reconnected to make it watertight (~$150).
Cost summary (this section only)
• Pump basket service/cleaning + retesting: <$50
• Electrical connection repair (watertight): ~$150

More details in last section = Valving about shoes.

This pump is not bonded ($100).

Board and Timer
The board and timer has two new timers, but it does not appear to have any GFCI breakers.
It is missing GFCI protection rated for the variable speed pump (Siemens type) and for the pool light.
Recommend updating with the proper GFCI breakers.
Estimated cost: ~$300 for parts plus ~$350 for electrician installation.
Cost summary (this section only)
• GFCI breakers + electrician installation: ~$650

Valves and Fittings
There are no valves present — only plumbing. The plumbing appears to have been updated around the 2006 era, with older heater copper connections still in place that have not been removed. The heater can be removed for $300–$500.
The pool equipment pad should be covered from the sun using UV mesh (~$50 on Amazon).
It would be wise to consider adding a check valve on the suction side of the pump and updating the booster pump hoses to hard plumbing, as there is some hodgepodge apparatus on the return side that would greatly improve flow and reliability. This work might run around $500.
Repainting and relabeling the equipment pad might run around $100.
Cost summary (this section only)
• Heater removal: $300–$500
• UV mesh: ~$50
• Check valve + hard plumbing upgrade: ~$500
• Repaint and relabel: ~$100
