Surface of the pool and spa is all original likely 25 years old and getting towards the end of its life cycle in the last 25%. Wear and leopard patterns present throughout mostly on the bottom. Would hope it has another 5 to 10 years of additional life remaining but it may be less. The way to know is when water loss occurs. Again I feel we are on the last 25% of its lifecycle possibly even the last 10%. Some calcium fissures / check cracking in the deep end middle which is common with moist sub soil environments.

Re plaster for this pool should run 8-12k+ when the time comes (soon).

Waterline tile is in original condition and relatively good shape for its age with no major issues seen. Some calcium buildup that can likely be removed for around $450 but nothing too substantial. Spillover from the spa to the pool is in relatively good condition with no major issues seen. Some very minor gaps at the corners that could likely be updated or touched up when the waterfall gets touched up. Waterfall needed now as many of the stones are loose and cracked and this waterfall area will likely need to be re-waterproofed. Waterfall will likely be around $1500 which would likely include touching up the spa spillover edge tile. Otherwise the waterline rock seems to all be secure. The only issue seems to be the waterfall itself which does not appear to be watertight anymore. Also the gap between the concrete and tile can be filled in with mastic ($500+) to help seal the distance due to concrete settling.

Water quality in relatively fair to damaged condition. pH and alkalinity high. Chlorine low. Calcium hardness and CYA levels normal but slightly low therefore water loss not likely but recommend recheck in 1 to 30 days to confirm. Recommend lowering pH and alkalinity which is a sign of organic matter living in the pool as algae present on bottom. Treatments should be performed likely for around $200 up to $375 to fully remove the algae present which is different than just over chlorinating and killing most of the algae versus doing treatments which will move phosphates enzymes and algicide.

Skimmer is due for parts update including weir door, float, float o-ring, new weighted basket, and lid all for less than $500 installed. Skimmer shows signs of heavy iron and/or chlorine wear, generally a sign it should be updated at next re-plaster stage if chlorine wear which is most likely since skimmers cost only $300 and are critical. No signs of movement on skimmer which is good so replacement at plaster not required but recommended. Main drains: two wall suction ports likely for waterfall pump and one for main drain making main drain not VGB compliant. Main drain would be updated at re-plaster for approx $1k+ for pool and $1k+ for spa. In the meantime all five main drain covers should be updated for safety at around $100 each to mitigate injury from old brittle covers. Spa main drain area also likely not VGB compliant.
Estimated total: Skimmer parts less than $500 plus 5 main drain covers $500. Optional future: skimmer replacement $300-1500+, main drain / suction ports updates 1k each x 3.

Recommend minor updates : tail, swivels, etc ($105 or less)

Could not see / test. Cover stuck. Recommend service ($125) to confirm status.

Pool light has condensation inside this original light can and should be updated for safety. Approx $150-1200 for the new light can depending on options and quality, and install is $400.

Spa light did not turn on and if it’s original as expected. Cost of a new spotlight as low as $150 up to $1100 and installation around $400.

Filter is original and older and overall relatively small in size for this sized pool. Ideally to save cost you can just update the filter element which will cost between $100-150 depending on quality and update the O-ring set and pressure gauge for around another $100 plus another $150 in service. But consider soon just replacing the entire filter as this filter is older and obsolete and no longer has replacement parts other than common service items. A replacement filter that is liked that is similar in size but slightly larger and more efficient would be the AquaStar PL 35,000 and that filter costs around $900 which is felt to be a better value versus updating this filter.

Filter pump is in working condition. It’s relatively new less than five years old and one of my favorite pumps. The only downside is it does not like direct sunlight for long periods of time so highly recommend getting it out of the sun ASAP using a simple UV mesh. For longevity purposes do minor service to the pump O-ring and replace the pump lid o-ring and replace the pump basket all for less than $100.

Waterfall pump is leaking from seal plate and/or shaft seal. This is usually a sign of a $500 repair but could update the wet end for around another $300 totaling $850 to $950 in repairs, or replace the entire pump with a variable speed pump as low as $350 to $450 on Amazon which would likely be the highest quality option. Installation around $450 on top.

Heater appears to be likely original or close to original overall. It is in good working condition but shows signs it has been recently worked on or updated. It is getting towards the end of its lifecycle. Would hope it has another 1-3 years of use left before replacement required but based on other signs really anticipate only 1-2 years before replacement may be needed. Cost for a new heater around $4800 plus installation around $1000 bringing total to around $6000.

The timer is being used as an on off switch which is fine but the GFI breaker for the pool lights appears to be older and due to be updated. Also do not see any GFCIs for the pump or equipment. It is likely that a subpanel with breakers should be installed here for safety at around $350 in parts or maybe more up to $550+ and an electrician will charge around $300 to $500.

Equipment pad here present is due to be repainted, relabeled, and covered from the sun using UV mesh all of this for around $350 installed. Recommend doing that ASAP.
