Hiring someone to service or remodel your pool is a significant investment—and a bad contractor can cost you thousands in repairs or safety issues. Before you sign a contract or hand over a deposit, you need to verify that the company is legitimate, properly insured, and qualified to do the work.
Why Credentials and Insurance Matter for Pool Work
Pool and spa work isn't just cosmetic—it involves plumbing, electrical systems, chemical handling, and structural modifications. A contractor without proper licensing or insurance puts your property and family at legal and financial risk. If an uninsured contractor is injured on your property, you could be liable for medical bills. If their work causes damage, you have no recourse.
Check State and Local Licensing Requirements
Licensing rules vary by state and county. Some states require pool contractors to hold a specific "pool contractor" license, while others fold it into general contractor or specialty trades licenses (plumbing, electrical).
Start here:
- Contact your state's contractor licensing board or construction board website—search "[your state] + contractor license verification"
- Ask the company directly for their license number and verify it online in real time during your conversation
- Confirm the license is active and in good standing (not expired or suspended)
- Check whether the license covers the specific work you need: pool cleaning, repairs, equipment replacement, or full remodeling
If a contractor can't or won't provide a license number, walk away immediately.
Verify Insurance Coverage
Pool contractors should carry at least three types of insurance:
General Liability Insurance — covers property damage and bodily injury claims (minimum $1 million is standard in the industry)
Workers' Compensation Insurance — required in most states if the company employs staff; protects you if an employee is injured on your property
Pool-Specific or Equipment Liability — some insurers offer specialized coverage for pool equipment installation and maintenance; this is especially important for remodeling or equipment replacement work
Request a Certificate of Insurance (COI) directly from the contractor, not a screenshot they text you. A valid COI includes the insurance company's name, policy number, coverage dates, and the name and contact info of the insurance agent. Call that agent's number to confirm the policy is active.
Don't accept verbal promises like "we're insured"—get it in writing every time.
Check References and Complaint History
A valid license and current insurance are table stakes, but they don't guarantee quality work.
- Ask for at least three recent client references (ideally from the past 12 months) and actually call them—ask about timeliness, cleanliness, final cost compared to the quote, and whether they'd hire again
- Search the company name + "reviews" on Google, Yelp, and the Better Business Bureau
- Check the BBB specifically for complaints filed and how the company responded
- Look at the state's contractor licensing board website for any disciplinary actions or settled complaints
A company with one or two complaints that they resolved professionally is less of a red flag than one with multiple unresolved issues.
Get Everything in Writing
Before work starts:
- Request a detailed, itemized estimate (not just a lump sum)—for a pool resurface, this should break down labor, materials, equipment removal, and any permits
- Confirm the project timeline in writing
- Specify what permits the contractor will obtain and whether permit costs are included in the quote
- Get a written warranty on parts and labor; typical pool work comes with 1–3-year warranties
- Define the payment schedule (common: 25–50% upfront, remainder upon completion; avoid paying 100% upfront)
Use a Comparison Platform
Finding and vetting individual contractors is time-consuming. Platforms like Mercoly let you compare and review trusted pool and spa service providers in one place, with credentials and customer ratings already vetted, so you can make a faster, more confident choice.
Frequently Asked Questions
Q: What should a typical pool cleaning service cost, and should it affect my credibility checks? A: Monthly pool maintenance runs $80–$150 depending on your region and pool size; price alone isn't a credibility indicator, but an extremely low quote from an unlicensed provider is a warning sign.
Q: Do I need to pull a permit for pool repairs, and is that the contractor's job? A: Permit requirements vary by location and scope—cosmetic repairs typically don't need permits, but replastering, electrical work, or equipment replacement often do; your contractor should clarify this in writing and usually handles permit applications for an additional fee.
Q: What's the difference between a "licensed pool contractor" and a "general contractor who does pools"? A: Some states require a specialized pool contractor license; others allow licensed general contractors or licensed plumbers to perform pool work; always verify the specific license matches your state's requirements for the work you need.
