I have to say that if it's not too late where they have to turn folks away because they are that good and will become popular and successful just by word-of-mouth, these are the best, nicest, most proficient, efficient and reliable pool people I have ever had the pleasure and honor of dealing with over the past 21 years that I've lived here in comack. Sign up before it's too late!

The workers are friendly, efficient and trustworthy! You can always feel confident in the jib they do since you get to deal directly with the owner, Frank Gransasso. He is always on site and is extremely professional and pleasant! We have referred many of our neighbors to him and everyone is always more than satisfied! We would absolutely recommend this company highly...they will not disappoint!!

I am looking to purchase a home and I was in need for someone to do a pool inspection. Unfortunately a lot of the companies I called would only work around their schedule. I only had time on Sunday. Frank was very accommodating with my schedule. He gave me a report of what will need to be done. Also he told me what he recommends doing right away and then what will need to be done in the future. I found that to be very helpful as he knows purchasing the home is already a big investment and then spending more money to fix the pool would be difficult. I highly recommend Frank. Thank you.

Frank and his entire staff have been amazing. They are all very respectful and reliable. Contacting Frank and the staff is extremely easy and they are quick to respond. Knowing how difficult 2020 has been, everyone who performed services on our pool was safe, considerate with observing distancing protocols, along with being respectful to everyone around. Thank you for everything. Looking forward to another season ahead.
