They refuse to fix my pool after two weeks. They decided to drop me instead of cleaning it. Disgraceful.

James went the extra mile to make sure our pool is ready for summer. Our pool pump broke and he tried his best to fix it but it just needed to be replaced being so old. He came to fix our pool pump way after hours and service the pool, did not leave us hanging at all.
Will continue to use for many other seasons.

Love Three Cousins Pool Service! They make pool ownership easy. They take care of everything. They are very responsive and helpful regarding maintenance in between service, scheduled service days, and back office bookkeeping. Highly recommend.

All the guys are hardworking, so this isn't meant to take anything away from them, but Bobby is our main guy and we're very happy about that!

Three cousins rocks !!! I had to get rid of my Previous pool company I had. They just stop showing up and run around stories. I had been with them for 5years I get it sometimes things happens I get it. But enough is enough. Three Cousins took care of my pool the entire summer and not one issue with my pool, chemicals was balance perfect. Closed my pool today and I can say that I made the right switch!!!!
Thank you three cousins see you in the spring!!!!!!!
Stay safe!!!!

Hands down the worst pool company I have ever encountered!

Three Cousins was hired this year to service the pool at a home that we rent, and both their service and level of professionalism has been horrific. When they first opened the pool, it remained green and cloudy for 4 weeks. Rather than really address the situation, once a week they would just pour in more chemicals, scratch their heads and tell us that eventually it would start to clear-up. A MONTH later it finally did, but only after they finally vacuumed it and told us a new pump was needed.

The weekly servicing is even more ludicrous

[Intro added in response to business owner feedback]
Final work product is excellent, scheduling is a bit ... laid back. The Three Cousins not only open/close pools, they offer creative solutions for the homeowner in need. They have open/closed our in-ground pool, power washed our home and exterior walkways, replaced a wooden gate, created a brick walkway and installed an interim drainage solution. They will shop for materials at Home Depot or the Pool Store if needed. Alternatively, you can provide all supplies.

We started using this company a few

Dealing with corporate pool services, I finally had enough. I was tired of being treated like a price tag. Then I came across Three Cousins, genuine and honest hard working men. They answered all my questions and gave estimates free of charge. They took there time to come to my house and talk face to face. I felt like I was being helped instead of being taken advantage of. They were very knowledgeable and I recently bought my closing pool cover from them. The price was worth it, compared to other companies. One of the best family owned business out there!

Did a great job on a custom pool cover, and did it quickly. I'l be sure to reach out to The Three Cousins again for any of my pool needs in the future.
