This was my 4th pool company in 3 years. It will be my last. They are amazing from all aspects both during the season and after. The summer is short so don’t waste time on a bad pool company. Use these guys.

We bought a new home with a pool last year in the early summer and got into quite a jam due to the previous owners. This company was kind to make recommendations for our situation even through it wasn't a problem they service. We eventually booked with them for weekly service and they have been great. Their reviews are well earned. Super professional, friendly, helpful, and reliable; I also appreciate the transparency around cost and timelines. Highly recommend.

We have been using Gran Sasso the last 3-4 years and are always happy with their service. Prior to using them we used two other pool companies and had a lot of trouble getting our water clear. Once we started using Gran Sasso our pool is ready to go within a few days of opening.

GranSasso pool services exceeded my expectations in every way each year. From their meticulous pool opening process to the seamless closing procedures, their attention to detail has been impressive. Their weekly pool maintenance service has kept my pool crystal clear and perfectly balanced throughout the season. The technicians are knowledgeable, professional, and always go the extra mile to ensure everything is in top condition. I highly recommend GranSasso for all your pool needs.

Gransasso & Company are always a pleasure to deal with, do a great job, and my pool is crystal clear in the spring. This year within 4 days of opening the pool the kids were already swimming!

I hired them to soft wash my entire house, clean my exterior windows, shine my gutters, and pressure wash my driveway, sidewalk, and porches. I highly recommend Waterboys Pressure Washing!

These guys are awesome. Our house looks amazing! Definitely recommend!! I thought I needed to repaint my house, turns out I just needed Waterboys. They saved us so much time and money.

Jon

Very professional!! I told my wife last night prior to their scheduled arrival this morning, that everyone I had contact with was very professional and that’s the way you run a business!
