From Our Website

We can do the first major clean-up and vacuuming of the season to get your pool on the right track for the summer following your pool being opened for the season. We offer an initial, one-time maintenance which would normally be typical of pools that need to be cleaned after the pool is opened or has been closed for a number of seasons. This involves cleaning the pool, removing the bulk of debris. This would include two of our technicians to perform the job and are charged hourly. Please call for further details.


Underwater Pool Masters provides three types of Pool Closings to choose from for your Above-Ground or In-Ground pool. Prices vary depending on your unique pool and equipment. We can customize your services so you get just the right closing package for your needs. All closings are performed by knowledgeable and experienced technicians. Please call our office at (508) 852-0590 to schedule. For all closings, customers must have pool water lowered 1 inch below the skimmer if blow-out gizmo is NOT being used, electricity on and available, gates and doors unlocked, and all necessary parts (white/black plugs, gizmos, covers, water bags, air pillows, cables/winches etc.) available by the pool.
