About Koko Head Pool Service
East Honolulu's most trusted pool professionals since 1995. One owner. One mission. Your pool, done right.
You Deserve a Pool Pro Who Actually Shows Up
If you've hired a pool company in East Honolulu before, you probably know the frustration: missed visits, rotating technicians who don't know your system, vague invoices, and a pool that never quite looks right. You shouldn't have to chase your pool service company—they should be chasing perfection for you.
That's exactly why Jim Costello founded Koko Head Pool Service in 1995. His son, Paul Costello, grew up in the business and has been keeping pools across Hawaii Kai, Kahala, Diamond Head, and every neighborhood in between crystal clear since 2000. Today, as the CPO-certified owner and operator, Paul personally knows each customer's pool, their equipment, and their expectations.
Many of his customers have been with him for over a decade. That kind of loyalty doesn't come from marketing—it comes from showing up every week, doing the job right, and being someone you can trust with your home.
CPO Certified Professional
Paul holds the nationally recognized Certified Pool Operator (CPO) credential — the gold standard in the pool industry. This means he's trained in:
- Advanced water chemistry — understanding the science behind balanced, safe water. Learn more about our pool chemistry services.
- Equipment systems — pumps, filters, heaters, salt systems, and automation. See our equipment repair services.
- Health and safety codes — meeting standards set by the CDC, state health departments, and industry organizations
- Energy efficiency — helping customers reduce operating costs without compromising water quality
This level of training sets Paul apart from most pool service providers in Honolulu. It's the difference between someone who "cleans pools" and a professional who truly understands your system. Read more pool care insights on our blog.

What Sets Us Apart
Same Face, Every Visit
Paul personally services pools in Hawaii Kai, Portlock, and Kahala. No rotating crews, no strangers on your property. You know exactly who's taking care of your pool—every single week.
Honest, Even When It Costs Us
When a customer's pump was failing, Paul told them their existing motor could be rebuilt instead of replaced—saving them over $800. We'd rather earn your trust for life than make a quick buck on one repair.
Built for Hawaii's Pools
Salt air in Portlock corrodes equipment faster. Iron-rich water in Haha'ione stains surfaces. Steep access in Hawaii Loa Ridge requires extra planning. We know every challenge because we've been solving them for 31 years.
We Answer the Phone
When a customer's pump died on a Sunday afternoon, Paul was there within 30 minutes. Call 808-399-4388 and a real person picks up—same day, every time.
Real Reviews from Real Neighbors
My wife has been maintaining our pool for a year. Lately it keeps getting greener and greener. She kept brushing, cleaning filters, back washing and using more shock, algicide etc but all to no avail. Based on the reviews I read I called Paul of Koko Head Pool Service. He came out the same day to inspect our system. It turned out cyanuric acid was too high and our sand filter was too small. He gave us a quote in a few hours. We drained and refilled the pool. Paul came back in a couple of days to install the new filter with glass filtering media. Paul was knowledgeable, professional and friendly. The cost was reasonable. Now the wife is happy and I am happy too. 6 Stars to Paul if there is such thing.
I called Koko Head Pool Service because I'm currently having problems with my pool pump and waterfall timer, and I'm considering changing pool service companies. Paul answered my call right away and offered to take a look at my pool problem immediately. He also followed up the next day. His responsiveness and reliable attitude is all I needed to make my decision using his service moving forward. He was professional, knowledgeable, answered all my questions, and gave me the confidence to trust his reliability. Thank you for caring!
Paul provides excellent weekly pool service, and we highly recommend Koko Head Pool Service. One example of Paul's excellent service is when he reached out during a recent rainstorm to see if we were in town. When he learned that we were out of town, he went over to pump our pool, preventing flooding on our lanai and potentially into our house. Appreciate you, Paul and team!
