GranSasso Inc. Swimming Pool Services 10 Walter Court, Commack, NY 11725

"We have been using GranSasso for over a year now and I can’t say enough good things! From replacing our pool filter, liner, and stairs to opening and closing the pool they have been amazing! Always professional, friendly, and on time! Shanon in the office always promptly responds via email to answer any questions I have had about the services they have provided us! HIGHLY RECOMMEND!!!"

"My husband and I could not be happier with GranSasso pool service. We moved into our home last December and were elated to open the pool, but were at a loss on how to maintain it properly as new homeowners. Everything was made seamless with help of GranSasso! Their customer service team is friendly, knowledgeable, and extremely responsive. They assisted with a repair, provided weekly maintenance (always on time, rain or shine and always incredibly helpful and informative and hard working), and made opening and closing a breeze. We received so many compliments on how blue and clean the water was. If you’re looking for an outstanding pool service, and looking to enjoy your summer stress free, look no further than GranSasso! Summer, Shannon, Frank and everyone are nothing short of a joy to work with! Thank you all for a stellar season. Already counting the days until the next!"

"Just switched over to GranSasso for pool closing and will utilize their maintenance services next season. They are a class act and really appreciate Frank, Shannon and the team for converting me over.. I love good service which is hard to find! Thanks Joe"

"We cannot say enough about GranSasso! Always professional, honest and our pool is literally crystal clear one day after opening! The guys do such a great job always leaving the pool area pristine! I love that the invoice has a section to check “gate closed” which is so important for pet owners. The girls in the office make scheduling a breeze and send reminders for services, appts, etc. would recommend them 100%. Picture posted is on the day of opening 5/18/23."

"I switched this year to GranSasso after the endless unreliability of my previous pool service provider finally got to me! From the pool opening to maintenance and closure, they provided a phenomenal service to plan and my budget. We finally had a summer free of pool related uncertainties, and my 3 boys were so grateful and happy about it!! Thanks everyone at GranSasso for your kind, courteous, and professional commitment!! We can’t wait for next summer."
