San Francisco Pool Maintenance — Chlorine
San Francisco's most trusted pool maintenance team, by the numbers.
Get Your Pool Assessment"How often do you come, and what exactly happens each visit?"
We visit on a fixed weekly cadence — same technician, same day, same window. You'll receive a digital service log within two hours of completion: water chemistry readings, equipment notes, and a photo of the completed pool.
Commercial properties and hotel basins default to twice-weekly service. Residential pools with heavy bather load can add a mid-week chemical check at no extra charge during summer months.

7-Point Chemistry Panel
Live targetsWhat we do when pH drifts: Our technician carries sodium carbonate (soda ash) and muriatic acid on every truck. Corrections happen same-visit. If drift exceeds 0.4 units, we schedule a complimentary mid-week re-check.
"What happens if my pH drifts between visits?"
San Francisco's municipal water supply runs between 7.8 and 8.2 pH — already alkaline before it enters your basin. Evaporation, bather load, and morning fog condensation push it further. Left uncorrected for 10 days, pH above 7.8 cuts chlorine's sanitizing efficiency by 40%.
Every Chlorine technician carries a full chemical kit. We don't just test — we correct on-site, then log the delta so you can see the trend over months, not just the snapshot from today.
The 48-Hour Guarantee
If water clarity is compromised within 48 hours of a scheduled visit for any reason within our control, we return at no charge.
"Can you service our rooftop plunge pool or hotel spa basin?"
Yes — and we're one of fewer than a dozen SF-licensed contractors certified for elevated aquatic structures. Rooftop pools face a distinct chemistry challenge: UV exposure is 30–40% higher above the fog line, burning through cyanuric acid stabilizer twice as fast as a ground-level pool.
Boutique hotel spa basins require a separate protocol: higher sanitizer residuals per CDPH Title 22, mandatory 15-minute contact time verification, and a posted inspection log. We provide the log binder, the chemistry, and the signature.

"Are you licensed for commercial aquatic facilities? What happens if we fail an inspection?"
We hold every license California requires for commercial aquatic service. More importantly: in 14 years and 2,340 pools, no Chlorine client has received a health code citation while under our contract.
If an inspector arrives unannounced, your on-site log binder documents every chemical reading for the past 12 months. We prepare that binder. We update it after every visit. You hand it over without anxiety.
"The health inspector walked in on a Tuesday morning. I handed her the Chlorine binder. She left in twelve minutes."
