I’m very satisfied with GL Pools. They have kept my pool and spa in great shape and keep me informed with a weekly email detailing the service completed. I would highly recommend their service.

I met GL Pools from my pool contractor as this is who he hired for the start up service. I was so impressed with the kindness and care of everyone I met/spoke to, that I hired them to maintain my pool after the initial start up service concluded. They do a top-tier job twice a week which keeps my pool sparkling perfection. Friendly, attentive, supportive, and empowering employees abound, and I couldn't be more grateful they service my pool.

We switched to GL pools several months ago. It has been the most wonderful experience and best decision we made for our pool service and weekly cleaning. They are responsive, respectful, honest, knowledgeable, friendly and really take the time to answer your questions and explain things in detail. Very good pricing too! Thank you to all the staff that takes care of us weekly and our repairs. Our pool looks amazing thanks to you. You guys are the best and we are so grateful to each and every one of you!

Called GL Pools for an estimate. I received a fast response and he scheduled the estimate quickly. Upon meeting with Ryan he was professional and seemed knowledgeable about our equipment. He provided us with a detailed estimate and took pictures of our pool which was presented in the estimate (very nice). I will definitely contacting Ryan for their service.

Have really appreciated gl pools. They're always really nice and we have random questions sometimes. They've taken care of our pool since it was built. The weekly emails help me too. All the techs have been great and Adriana is our latest. 10/10 recommend.

I think GL is a very good pool service company. The repair guy in my area, Ken Hirsch is great. Always explains everything and i can count on the problem being fixed. Their weekly service techs are all very good and personable. The only thing I don't always like is that they change techs in my are frequently. I have had probably 6 or 7 different service guys and gals in the past 3-4 years. Like I said, they are all trained well, but it seems that as soon as we get used to the same person and he/she gets used to our pool, they are gone. Overall, pretty happy with GL Pools!
