I have been a happy customer for a couple of years. This is my review of their "service" from Feb. 2026 - Aug. 2026
2/3/2026 Filters cleaned
2/17/2026 Pool time fixed
4/27/2026 Spa timer pin fell 7 pm
5/30/2026 Spa timer pin fell 6:30pm
6/18/2026 the pool is going on at 10:30 am
6/19/2026 I asked Diego to reset the pool to 9 am
6/20/2026 Pool ends at 2:50 / Spa is on at 9am.
The pin was changed to 2 pm
6/23/2026 Diego changed the time FORWARD - right on front of me
6/242026 Diego fixed the time. i learned how to set the timer
6/30/2026 Black Aglae complaint. Request to begin taking pictures of timers at end of every visit.
CWS started with a cooper treatment
pool 8:20 - 2:20 / Spa 3:30 - 4:30
Began babysitting Diego
07/21/2026 Diego is showing up around 2pm.
07/28/2026 Diego is showing up around 2pm
His window has been from 9 - 11 am for over a year - no communication of a time change
07/31/2026 I had the water tested at Leslies and it came back with 50% quality score.
the water chemistry is all out of whack.
Phosphates at 1339
TDS at 3600
I essentially asked CWS what i am paying them for
8/4/2026 in an effort to correct the water quality, CWS gave the pool a phosphate treatment using Orenda PR-10000 phosphate remover. We agreed that I would call when the pool is clear and they would clean the filters.
8/7/2026 I called CWS to schedule filter cleaning on 8/12/2026
8/11/2026 Regular weekly maintenance with Diego.
8/11/2026 CWS called after weekly maintenance visit to reschedule filter cleaning for later in the week. He "didnt know why" he was scheduled for a bigger job.
8/12/2026 I had the filters cleaned by a different company. I got lucky. This company said that CWS knew exactly what they were doing and that delaying the filter cleaning would have caused the filter to crack; damaging my property.
And here is what a crack in the DE filter means: When a diatomaceous earth pool filter cracks from pressure, it either means an internal part (like plastic manifold) has split, causing DE powder to blow back into the pool or the external outer tank has ruptured, which creates an extreme safety hazard by spraying water or violently bursting.
To CWS's credit as of Aug. 17, 2026:
phosphates are 471 (1339 on July 31)
TDS n/a (3600 on July 31)
As of Aug 12, 2026, The water is circulating like a champ now compared to what it was PRIOR to the phosphate treatment! In hindsight I believe that Diego was using something he calls "soap" after he's cleaned the pool and this"soap" gets smaller particles in the middle easier to collect. This soap doesnt bubble, it is mystery soap that I never saw him use last summer. Soap also does a great job of clogging the grids in the filter. And, if the pH or alkalinity is off, that also helps to clog up the filter. These and I'm sure there are other factors I am unaware of, that have contributed to crappy water circulation.
CWS seems to have had a plan to create an environment where the water wasnt circulating well, then reduce needed chemicals, creating the algae issue. After a month of copper algaecide treatment (because I bitched about it), they killed the bloom, though the dead bloom is still on the sides of the pool and looks like shit. From the algae bloom to the delay in cleaning the filter, that is 2nd attempt to 1) damage my property, 2) breach of contract, 3) negligence / shirking their professional responsibilities in about 45 days.
I am still wondering why I allowed CWS to clean the filters in February when historically, CWS has always cleaned them late May / Early June. Something happened in having the filters cleaned in February that contributed to all of this.
I had another pool company look at my pool, and the first thing they said was the pH is too high, and they were right because I had the water tested at Leslies. None of this is rocket science, CWS knew exactly what they were doing. They were purposefully shirking their professional responsibilities.
This is my awesome experience from Feb - Aug of 2026 with CWS. All this for a whopping $250.00 a month!
The kicker of it is, I have been with this company since mid 2024, so almost 2 years now with zero issues. Something has changed in their decision making and transparency over the last 7 months that has spoiled their 1) overall service, 2) my trust in their ability, 3) my confidence in them moving forward. read more
