Pool closing service

Pool season is everyone’s favorite, but when it is time for the summer fun to end, ensuring your swimming pool is appropriately prepared to close for the season is very important. If you have yet to winterize your pool, you run the risk of freeze damage, pool cracking or leaking, and other expensive damages that can take place. To avoid having to pay for costly repairs or impact how quickly you can use your pool when it comes time to reopen again, it is best to hire a professional swimming pool company to perform quality pool closing and winterization services.

From the first swim to the final lap in a season, Dolphin Pool Services, LLC is here to guide you and your pool through the seasons.

Our certified pool technicians will make sure that you have peace of mind all winter long.

When should you close your pool?

We recommend closing your pool when the water is consistently below 60 degrees Fahrenheit. However, If you live in an area with several trees, leaves can quickly become your swimming pool’s number one enemy and nightmare. When this is the case, we recommend going ahead and closing your pool before the leaves take it over and clog the filtration system and stain your pool!

Closing your swimming pool at this time will also help minimize and prevent algae and bacteria growth during the colder months. The last thing any pool owner wants is to open their swimming pool in the spring and find a green pond. If you’re unsure if you should close your pool or not, please contact our service department for more information.

Very professional staff for all activities for our complete pool refurbishment. Amazing! Very patient with my decision making and very competitive price (I got 4 other estimates). They did everything they said they would. We absolutely love the pool and feel good about the work and appreciate their support through all of it.

After five years of service, still continue to sing praises about this company. My experience with Dolphin has always been top notch and looking forward to another great year of pool service with them. Pool always cleaned to high standard, pictures of pool sent to me during each visit, high quality products, etc.

Dolphin Pools (with no guarantee of future work) came to the rescue and had my pool back in working order within several days. Roman and his team's quick response and rapid repair along with their knowledge and professionalism made it easy to discontinue using the company I had used for many years.
