Pool Opening & Closing FAQ
Most Long Island pool owners open their pools between mid-April and late May. We recommend opening when daytime temperatures consistently reach the mid-60s. Opening earlier prevents algae buildup that occurs in warming, stagnant water under winter covers.
We recommend closing your pool between late September and mid-October on Long Island. Closing before the first hard freeze protects your plumbing and equipment. Water temperature should be below 65°F to minimize algae growth during winterization.
Our pool opening service includes removing and storing the winter cover, reinstalling ladders and accessories, reconnecting pumps and filters, inspecting all equipment, filling the pool to proper level, balancing water chemistry, vacuuming debris, and running the system to verify proper operation.
Pool winterization includes lowering the water level, blowing out all plumbing lines, adding antifreeze to lines and skimmers, adding winterizing chemicals, removing and storing ladders and accessories, draining pumps and filters, installing winter plugs, and securing the winter cover.
