How to Find a Trustworthy Local Pool Cleaner (Complete Checklist)

Hiring a pool cleaner feels simple until something goes wrong — overchlorinated water that damages your liner, a missing piece of equipment after a visit, or a technician who just stops showing up. Most bad hires happen because homeowners skip a few key checks. This checklist takes 20 minutes and protects you from 90% of the problems.

1. Verify Licensing (Where Required)

Several states require pool service technicians to hold a license or certification. California, Florida, and Texas have specific requirements for contractors who perform structural work or handle certain chemicals above a certain concentration. If a cleaner is operating without a required license, you have no recourse if something goes wrong — and your homeowner's insurance may not cover damages.

How to check: Ask for their license number and verify it on your state contractor licensing board's website. Reputable cleaners list their license number on their website, truck, or invoice. If they can't provide one, ask why — and seriously consider moving on.

2. Confirm They Carry Liability Insurance

Pool service involves chemicals, electrical equipment, and access to your property. Liability insurance protects you if a technician accidentally damages your pool, cracks the deck, or is injured on your property. Ask for a certificate of insurance (COI) and verify that it's current. General liability coverage of at least $1 million is standard for professional pool service companies.

3. Ask for References — Then Actually Call Them

Anyone can fake Google reviews, but a bad actor is unlikely to have three satisfied customers willing to take a phone call. Ask for two or three references who have used them for at least one full season. Key questions to ask references:

• "Did they show up on the scheduled day, consistently?"
• "Did they communicate when something came up?"
• "Did your water chemistry stay balanced throughout the season?"
• "Were there any billing surprises?"
• "Would you hire them again this year?"

4. Ask About Their Chemical Approach

A professional cleaner should test your water chemistry every visit and document the results. Ask them which parameters they test (at minimum: free chlorine, pH, total alkalinity, and calcium hardness) and how they communicate those results to you. Some services send a text or email with test results after every visit — that's a sign of a thorough operation. If they can't tell you what they'll test or how they'll document it, that's a red flag.

5. Get Everything in Writing

Before the first visit, get a written service agreement that specifies:

• Exactly what's included in each visit (skimming, brushing, vacuuming, chemical testing, basket emptying)
• Whether chemicals are included in the price or billed separately
• Frequency and scheduled day of visits
• How to cancel or pause service
• What happens if they miss a visit
• Payment terms and billing cycle

If a cleaner resists putting things in writing, that tells you everything you need to know.

6. Do a Background Check on the Business

A quick Google search of the company name plus your city should surface any complaints. Check the Better Business Bureau (BBB), Yelp, Nextdoor, and Google Reviews. Look for patterns — one bad review is noise, three bad reviews with the same complaint (no-shows, billing disputes) is signal. Also verify that the business has a real address, not just a phone number. A sole proprietor working from home is fine, but they should still have a consistent, verifiable presence.

7. Watch for These Red Flags

• No written contract or service agreement
• Refuses to provide a COI or license number
• Asks for payment in cash only
• Pressures you to decide immediately or claims a "limited-time" rate
• No verifiable business address or online presence
• Can't explain what chemicals they use or why
• Doesn't want to meet you in person or see the pool before quoting

8. Start With a Trial Period

Even after doing everything right, it's smart to start with a month-to-month agreement rather than locking into a full season contract upfront. This gives you an easy exit if the cleaner underperforms without the hassle of a contract dispute. Once you've had 4–6 visits and are happy with the service, you can negotiate an annual rate.
