Hiring a pool service company is different from hiring most home service providers. The technician who shows up has access to your backyard, your pool’s chemicals, and equipment that can be costly to repair if handled the wrong way.
A short conversation before you sign up usually tells you everything you need to know. Here are the seven questions worth asking:
- Are you CPO certified?
- Are you licensed and insured?
- What is included in a standard visit?
- Do you offer seasonal services like opening and closing?
- How do you communicate updates and issues?
- What happens if something goes wrong during a visit?
- Can you provide references or reviews?
The rest of this guide walks through each question, why it matters, and what a strong answer sounds like.
Why It’s Worth Asking Questions Before You Hire
Pool maintenance mistakes are not always obvious right away. A skipped filter cleaning or a missed chemical test does not look like a problem on the day it happens. It shows up two or three weeks later as cloudy water, a stained surface, or a piece of equipment that failed earlier than it should have.
A pool service company that cuts corners on testing, certification, or communication often looks no different from a good one, at least on the surface. The questions in this guide are designed to surface those differences before they show up in your pool, not after.
The 7 Questions to Ask Before Hiring a Pool Service Company
1. Are You CPO Certified?
CPO stands for Certified Pool Operator, a credential issued through the Pool & Hot Tub Alliance (PHTA). The certification covers water chemistry, filtration, equipment operation, and pool safety standards.
A CPO certified technician has been trained on the same fundamentals that public pool operators are required to know, even though residential pools do not carry the same legal requirement. Asking about this certification is one of the fastest ways to gauge whether a company’s water chemistry knowledge goes beyond adding chemicals until a test strip looks right.
You can read more about what the CPO program covers on the PHTA website.
Desi Boys Pool Services is CPO certified, which shapes how our team approaches water balance, from total alkalinity, to pH, to sanitizer levels, on every visit.
2. Are You Licensed and Insured?
Licensing requirements for pool service companies vary by state and town, but insurance should not.
General liability insurance protects you if something goes wrong on your property, whether that is accidental damage to a pool feature, a piece of equipment, or even your landscaping during a visit. Workers’ compensation insurance protects the technician, and indirectly protects you from certain liability if someone is injured while working on your property.
A company that hesitates or gets vague when asked about insurance is worth a second look. A company with nothing to hide will usually answer this question directly, and many can provide proof of insurance on request.
3. What Is Included in a Standard Visit?
This question often reveals the biggest gap between pool service companies. The term “pool cleaning” can mean very different things depending on who you ask.
A thorough standard visit usually includes skimming the surface, brushing the walls and steps, vacuuming the floor, emptying skimmer and pump baskets, testing and balancing the water, and a quick visual check of the equipment pad. The CDC’s Healthy Swimming guidance lists regular water testing as one of the basic steps in keeping pool water safe, and it should be a standard part of any cleaning visit, not an upgrade.
Some companies stop at skimming and a quick chemical dose. Others, like the weekly pool cleaning included in our full service offerings, treat each visit as a chance to catch small issues, like a rising filter pressure reading or a slow leak, before they turn into bigger ones.
Ask for a specific list of what is included, not just a general description, and compare that list against the price you are quoted.
4. Do You Offer Seasonal Services Like Opening and Closing?
Pool opening and closing are two of the most equipment heavy visits of the year, and they are also two of the easiest to get wrong if rushed.
A company that handles weekly cleaning but not seasonal opening and closing means coordinating between two different providers, which can create gaps, especially if something gets missed during a handoff between companies.
Our pool opening service and pool closing service in Mercer County are handled by the same team that provides weekly maintenance, which means the person closing your pool in the fall is already familiar with how it has run all season.
5. How Do You Communicate Updates and Issues?
A pool service visit usually happens while you are at work, asleep, or simply not home. The only way you know what happened is if the company tells you.
Ask how the company shares updates. Some send a text or photo after each visit. Others leave a note at the equipment pad. Some only reach out if there is a problem, which can leave you wondering whether no news means everything is fine, or that no one showed up at all.
Clear communication matters most when something needs attention, like a part that is starting to wear out or a chemical level that needs more frequent testing for a few weeks. A company that flags these things early gives you time to plan, rather than facing a surprise repair bill later.
6. What Happens If Something Goes Wrong During a Visit?
Even careful technicians occasionally find something unexpected, like a cracked fitting, a failing pump, or a tear in a liner.
Ask how the company handles this. Do they call before doing any work beyond the routine visit? Do they provide a quote for additional repairs, or do extra charges show up on the bill without warning?
A company that pauses to call you before starting any extra work, and explains what they found and why it matters, is treating your pool the way they would want their own treated.
7. Can You Provide References or Reviews?
References and reviews will not tell you everything, but a consistent pattern across several reviews usually says more than any single conversation can.
Look for reviews that mention specific details, like communication, reliability of scheduled visits, and how the company handled an unexpected issue, rather than only star ratings. A company that has served the same neighborhoods for a while will often have nearby homeowners who can speak to their experience directly.
Red Flags to Watch For When Hiring a Pool Company
A few patterns tend to show up again and again with companies that do not work out long term.
- Vague or evasive answers about insurance or certification. A direct question deserves a direct answer.
- Pricing that changes significantly once you mention specific services. A quote should be based on your pool and your needs, not on guesswork over the phone.
- No scheduled visit times, or visits that happen whenever someone is free. Consistency is part of what you are paying for.
- Pressure to sign a long term contract before a single visit has happened. A company confident in its service usually does not need to lock you in immediately.
- No reliable way to reach anyone except a single phone number that often goes unanswered. Communication problems before you hire rarely improve after you do.
None of these red flags are automatically disqualifying on their own, but more than one at once is worth paying attention to.
What Makes a Pool Service Company Trustworthy Over Time
Trust with a pool service company tends to build the same way it does with any other ongoing relationship: through consistency.
A company that shows up on schedule, week after week, without needing reminders, is doing something that sounds simple but is surprisingly rare. The same goes for communication. A quick note about a rising filter pressure reading or a fading pool light, sent before it becomes a problem, says more about a company’s approach than any sales conversation.
Certifications matter too, but only if they are maintained. CPO certification requires renewal, and a company that keeps its team current is signaling that water chemistry knowledge is an ongoing priority, not a one time box that got checked.
Finally, a trustworthy company is upfront about what is and is not included in a visit. If something falls outside the scope of a standard appointment, like a major repair or an equipment replacement, a good company explains that clearly rather than letting it show up as a surprise.

FAQ: How to Choose a Pool Service Company
What does CPO certified mean for a pool company?
CPO stands for Certified Pool Operator, a credential from the Pool & Hot Tub Alliance covering water chemistry, filtration, equipment, and safety standards. A CPO certified technician has formal training in these areas, beyond general cleaning experience.
How much should I expect to pay for a pool service company?
Pricing depends on factors like pool size, how often you want service, and what is included in each visit, such as testing, cleaning, and equipment checks. The most reliable way to know what a service will cost for your specific pool is to request a free quote based on your pool’s size and needs.
Should I sign a contract with a pool service company?
Many pool service companies use seasonal agreements rather than long contracts, which is common in this industry. It is reasonable to ask what the agreement covers, how scheduling works, and how to make changes if your needs shift during the season.
What’s the difference between pool cleaning and full pool maintenance?
Pool cleaning often refers to surface tasks like skimming and brushing. Full pool maintenance typically includes cleaning plus water testing, chemical balancing, and equipment checks, which together keep the pool both clean and properly balanced.
How do I confirm a pool company is licensed and insured?
Ask the company directly for proof of general liability insurance, and ask whether their technicians carry workers’ compensation coverage. A company that regularly works on residential properties should be able to provide this information without difficulty.
How often should a pool service company visit during the season?
Weekly visits are standard for most residential pools during swim season, since this matches how often testing and cleaning typically need to happen. Pools with heavy use, nearby trees, or specific equipment concerns may benefit from more frequent visits.
Final Thoughts
Choosing a pool service company does not need to feel like a guessing game. Certification, insurance, a clear list of what each visit includes, and a company that communicates before problems grow are the things that separate a good long term fit from a frustrating one.
