The surface is plaster. On the beach shelf there is minor check cracking present, likely due to the fact that this is slightly too shallow and has been damaged by the sun. Still, it likely has between 1 and 10 additional years before the check cracking causes the plaster to be removed and expose its lower layer. The spa on its steps also has check cracking, but more concerning is the delaminating plaster on the north side of the bench, indicating that the spa plaster is likely leaking and will require a plastering at the very least in the spot itself at a cost of $2500 to $3500. The pool plaster is in slightly better condition but not much better, and may have another 1 to 5 years of additional life, but no guarantees. The pool surface has check cracking present throughout, including the main deep end. Note that it could also be structure issue cracks on the bottom of the pool and not necessarily just check cracking, therefore replastering and attention to these issues is more likely the recourse versus just the spa. The surface is heavily mottled and overall in relatively poor condition for its age, with wear markings present throughout. It is almost certain that much of these wear markings are nearly down to the gunite in some locations. Therefore, plastering the pool and the spa at the same time would be the best value and wise choice, to resurface the pool and spa together. Expect a cost of around $12000 to $15000 in season, and out of season closer to $10000 to $12000.
Section total: $10000 to $15000.

The waterline tile all appears to be present and in overall fair condition for its age. The only areas of major concern are on the spa spillover area, and this all appears to be rock slate versus the waterline tile itself. The rock coping appears to all be present, with significant wear for its age. It is likely all due to be reworked in the next 1 to 10 years and will likely cost $2000 to $5000 to update, depending on new product or existing product, new product being more expensive and existing product being less expensive. The decorative rock work complementing the coping also is all present, but loose rock work is seen, mostly on the west side of the pool, but for the most part in every section there are loose rocks or rocks about to be loose. The most notable issue is the rock waterfall, with gaps more than 2 inches, indicating the waterfall is no longer watertight and will need to be addressed. The waterfall to be re-waterproofed would likely be between $1000 and $2000. The rock work around the pool would likely be between $2000 and $5000 to update. There are some other areas of concern, like the concrete decking on the south side of the pool near the skimmer, where it has lifted and separated, and most notably around the skimmer will likely need to be removed and redone, especially around the skimmer as there is significant movement in this critical area. This alone would likely be between $2000 and $3000. Next is the spa spillover rock work. This would likely run between $500 and $1500 depending on issues present on the spillover section. Last, there are gaps between the rock coping around the entire pool for the most part, and that has been filled in with mastic, but it is also due to be updated in several locations as there are many spots where trip hazards are forming or have formed and will need to be ground and reset, likely between $2000 and $5000 for that as well.
Section total: $9500 to $21500.

The water quality indicates that there is low free chlorine and significant total chlorine, indicating there is organic matter growing, which is seen as algae present throughout. It will likely require treatments around $375 or more, which should also include raising the cyanuric acid level slightly and lowering the pH and alkalinity. Also note that the CYA and calcium hardness levels are low, indicating that this is new water, a.k.a. water loss is likely present, which makes sense as many significant signs of that are seen.
Section total: around $375 or more.

Next is the main drains in the pool and the spa. There are two main drains in the spa. The covers themselves appear to have been updated, likely in the past 5 to 10 years. There are two main drains in the pool and two on the wall, likely for the waterfall, and one on each skimmer, for a total of six covers in the pool and two covers in the spa. All eight should be updated at a cost of around $200 each if they are older than seven years, which based on their overall condition, they likely are.
Section total: $1600.

Next is the skimmer. There are two skimmers in this pool. Both skimmers are original. Both skimmers seem to have trouble with their collar being raised slightly, likely due to the movement seen around the skimmers from the rock coping. Still, both skimmers have all parts present, but are due to be updated with a new weir door, new float, new float O-ring, new weighted basket, and new skimmer lid on both skimmers, at a cost of around $500 each installed, so $1000 total.
Section total: $1000.

Next is the bottom cleaner. The bottom cleaner is older. It needs a new tail, tires, likely hose, potentially a new net, backup valve, and service to the unit itself. The cost would likely run between $200 and $400 to update this unit, versus a new unit complete is between $500 and $600 and would likely be the best value considering this unit’s condition.
Section total: $200 to $400 to update, or $500 to $600 for a new unit.

Leaking - recommend likely minor service ($20+)

There are two pool lights installed, color changing halogen. They are operational at this time but they are filled with condensation and should be updated for safety. The cost of a like light is around $1200 plus installation of $400 each, and there are two lights.
Section total: $3200.

There is one spa light. It is a 6 inch light. It is also color changing halogen. Updating is recommended due to condensation also being present. The cost on a new light like this is approximately $1150, plus labor install $400.
Section total: $1550.

The filter appears to be leaking continuously, either out of its return union or the filter itself. The lower half of the shell filter is older, heavily sun beaten, and in relatively poor condition. It could just be leaking out of its tank O-ring, requiring a new tank O-ring at around $100, plus the band is nearly fully tight, indicating the band is due to be updated at a cost of around $400. It will likely need new filter elements at the cost of around $600, along with service of around $150, plus a tank O-ring set at around $200, and a new pressure gauge updated at around $50, which would not be recommended versus just simply installing a new filter at a cost of around $800 up to $2200, plus around $800 installation and service.
Section total: around $1500 to repair, or $1600 to $3000 for a new filter installed.

This filter pump - is running currently and appears to be leaking fairly steadily out of its return connection. This pump is from 2014. It is a variable speed IntelliFlo Pentair pump. Its motor is degraded and showing signs of failure in the near future. At the very least the motor will need to be updated at a cost of around $1200 and around $400 in labor to install on this pump, assuming the wet end is still in shape and secure, which is not guaranteed. Versus a new pump, a new Pentair IntelliFlo i3 filter pump is around $1600 up to $1900, plus around $800 to install and program.

Section total: around $1600 for motor, or $2400 to $2700 for a new pump installed.

Next is the spa jet pump. It is nearly identical to the waterfall pump, but it is a 1.5 hp pump. It is also buzzing. Same issues likely persist on this pump as well. It could be a simple capacitor fix for less than $100, or more likely a replacement at a cost of around $1200 plus $800 install, just like the previous pump.
Section total: less than $100 for a capacitor, or $2000 for a new pump installed.

The waterfall pump is next to the filter pump, in between the jet pump. This pump is buzzing, humming, and not turning on completely. It could just be a simple capacitor fix, less than $100, to help bring this pump to working status. But judging by how this pump looks, and knowing this particular model pump, there are likely more issues as the seal plate itself is low quality, and the pump will likely just need to be replaced due to its age and condition. This is currently a one horsepower pump, and a like pump may be a SuperFlo VS, and that pump is around $1200 and installation would be around $800.

Section total: less than $100 for a capacitor, or $2000 for a new pump installed.

The heater does turn on, function, and operate, but likely because there was no propane, this heater was not able to fire. Still, due to the overall condition of this heater it was not expected to function perfectly, so it is a surprise that it is functioning normally minus firing. Typically heaters like this last up to 15 to 20 years. This one appears to be 13 years old, and sure it’s towards the end of its life cycle, but some remaining life is likely. Still, the cost of a new heater like this is between $3000 and $4000, and installation will be around $1000 when the time comes, but at this time it does appear to be in potentially fair / poor working condition.
Section total: $4000 to $5000.

The board and timer is an IntelliTouch i9+3 and in working condition, with a wireless remote antenna. Currently the filter pump indicator light is stuck on, even though it is not accurate, and therefore is showing signs of this board maybe nearing failure due to age and overall condition. The cost on a new board such as this is around $1200 plus $400 installed. If there is no wireless remote present, that would make it difficult to program this panel. A wireless remote is essentially required at a cost of around $700 and up. Note that a phone connectivity kit would be a better value at about that same price of $700, and would allow connecting it to the internet and thus a phone in an app. Additionally, the breakers are not GFCI except for the plug, which is GFCI. That is great. The breakers should still be updated to GFCI for at least the variable speed pump and the pool lights. The variable speed pump breaker is around $150 and the pool lights are around $50. At that same time the plug breaker should also be updated, as it is less than $50, for safety. An electrician would also charge around $400 to install.
Section total: $1600 for a new board, around $700 for a remote or phone kit, plus less than $650 for GFCI updates.

The equipment pad plumbing is all in damaged condition, leaking in several locations and heavily damaged. On the return side there is a leaking three-way valve and older actuators. On the suction side there is one actuator and three three-way valves. On the return side there are two actuators and two three-way valves, as well as two check valves. Due to the overall poor condition of everything, it would be more likely that a cut out and replace, at $1500 to $2800, would be the best value versus pieces of repair work needed now at $1500 and up. The higher cost of $2800 would be to replace actuators and valves, repaint and relabel, and replace unions and check valves, all new, complete, and fresh. That would be the recommendation.
Section total: $1500 to $2800, with $2800 recommended.
