How to Hire a Pool Cleaning Service You Can Actually Trust (7-Point Checklist)
A good pool service is nearly invisible: your water stays clear, your equipment lasts, and you never think about chlorine. A bad one costs you far more than the monthly fee — a replaced pool heater runs $2,500 to $5,500, and a green-to-clean recovery after a botched season can hit $400 or more. Here's how to tell the difference before you sign anything.
Know What "Normal" Looks Like — Price and Scope
In most US markets, weekly full-service cleaning runs $100 to $200 per month, depending on pool size, screen enclosure, and whether chemicals are included. Chemical-only service (they test and balance, you skim and vacuum) typically runs $60 to $110 per month. If a quote is dramatically below that range, ask what's missing — usually it's chemicals billed separately, or visits that last five minutes.
A legitimate weekly visit should include: skimming the surface, emptying skimmer and pump baskets, brushing walls and steps, vacuuming as needed, testing and balancing water chemistry, and a quick visual check of the pump, filter pressure, and salt cell if you have one. That's a 20–30 minute stop for an average residential pool — not a drive-by chlorine dump.
The 7-Point Vetting Checklist
- 1. Verify licensing where required. States like Florida, California, and Texas regulate pool contractors for repair work. Ask for the license number and look it up on your state's contractor board website — it takes two minutes.
- 2. Ask about certification. A CPO (Certified Pool Operator) or NSPF/PHTA certification means the technician actually studied water chemistry, not just watched someone else do it. Not legally required for cleaning in most states, but it separates pros from guys with a truck and a net.
- 3. Confirm insurance — in writing. Ask for a certificate of insurance showing at least $1 million in general liability. If an uninsured tech cracks your spa spillway or floods your equipment pad, that bill lands on you.
- 4. Ask how they document visits. Good companies send a photo and chemical readings after every stop (many use apps like Skimmer or Pool Brain). If they can't show you proof of service, you're paying on faith.
- 5. Check reviews for patterns, not scores. A 4.6 with 80 reviews beats a 5.0 with 6. Read the 2- and 3-star reviews specifically — repeated mentions of missed visits or surprise charges are the tell.
- 6. Ask who actually shows up. Is it the owner, a trained employee, or a subcontractor? Turnover-heavy companies rotate strangers through your backyard. Ask: "Will I have the same tech each week?"
- 7. Get the exclusions in writing. What happens after a storm? Is filter cleaning included or a $75–$150 add-on? Are algae treatments extra? Vague answers now become invoices later.
Red Flags That Should End the Conversation
- Cash only, no contract, no invoice. You'll have zero recourse when something goes wrong.
- "We don't need to test — we can eyeball it." Free chlorine, pH, and cyanuric acid can't be eyeballed. Chronically high CYA (over 100 ppm) makes chlorine nearly useless, and you'd never see it.
- Pressure to prepay months in advance at a steep discount. This is the classic exit pattern for companies about to fold.
- They diagnose expensive repairs on day one without showing you readings, photos, or the failed part. Get a second opinion on anything over $300.
- No answer on how they handle service gaps. A pool skipped for two weeks in July can turn green in days. Ask what their coverage plan is when your tech is sick or on vacation.
Questions Worth Asking on the First Call
- "What exactly is included in the monthly rate, and what's billed separately?"
- "How do you handle chemistry for salt pools?" (If they seem confused, keep looking.)
- "Can you send me a sample service report from a current customer?"
- "What's your policy if my pool turns green while under your care?" The right answer: they fix it at their cost, because it shouldn't happen.
The Bottom Line
Spend 30 minutes vetting up front and you'll likely keep the same reliable service for years — most homeowners who churn through three pool companies in two summers skipped exactly the steps above. Your pool is a $40,000+ asset sitting in the sun; the person maintaining it should be licensed, insured, certified, and accountable.
If you'd rather skip the trial and error, reach out to a trusted local pool cleaning pro and ask them these exact questions. A company with nothing to hide will welcome every one of them — and that's usually the company worth hiring.
