What East Honolulu Pool Owners Say
Paul promptly arrived at my residence within 30 minutes of my call to assist me with troubleshooting an issue. Subsequently, he replaced a part on the filter on the same day, providing exceptional service and demonstrating his professionalism. I am confident that he will be the preferred provider for all my future pool maintenance needs. His service is truly exceptional, and a five-star rating does not adequately reflect his capabilities.
Kokohead pool service is the best choice you can make for your pool care. Paul was quick to respond and quickly diagnosed the problem with my salt water chlorinator. He then made sure to test and balance out my chemical levels. You will not regret calling them. Highly recommend for quick friendly service.
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.
