Pool Opening and Closing Service in Southern Maine Done Right for the Maine Climate
A pool opened and closed correctly survives every Maine winter and comes back ready to swim. Mowry Brothers Pool Company handles seasonal service across York County and Southern Maine the way it needs to be done in this climate.

What Does a Professional Pool Opening and Closing Include in Maine?
A professional pool opening includes removing and storing the winter cover, reinstalling equipment, inspecting all components for winter damage, filling to correct water level, starting up and testing filtration and sanitization, and balancing chemistry. A professional closing includes balancing chemistry, blowing out all plumbing lines, winterizing equipment, lowering water level, and installing a properly fitted winter cover.
Why Maine Pool Closings Are Different From Other Climates
Southern Maine pools face a genuine freeze threat from November through March. Any water remaining in plumbing lines that is not removed will freeze, expand, and crack the pipes — underground or at the equipment pad.
The closing process Mowry Brothers uses is calibrated to Maine's climate — not the same generic procedure used in milder states. Every plumbing line is fully blown out with compressed air. Equipment is winterized correctly for your specific setup.
A proper closing typically costs less than a single plumbing repair caused by an improper one. If you have been closing your own pool and are uncertain whether the lines are fully cleared, having Mowry Brothers perform this service establishes the right baseline.
Pool Closing Covers
Not all winter covers provide the same protection. A properly fitted solid cover or safety cover protects the pool, simplifies the spring opening, and is safer in households with children and pets.
If your current cover creates a difficult spring opening, Mowry Brothers can advise on cover options during a closing appointment.

Pool Opening and Closing FAQ for Maine
Most Southern Maine pools are opened between Memorial Day weekend and mid-June. Opening too early when overnight temperatures still drop near freezing can make chemistry management difficult. A heater extends your options on timing.
Most York County pools are closed in September or early October before overnight temperatures consistently drop below 40 degrees. Closing too late risks an unexpected freeze event before the pool is properly winterized.
Water remaining in pool plumbing lines freezes, expands, and cracks the pipe — underground lines, equipment connections, and fittings all can fail. The damage is not visible until spring when the pool is refilled and pressurized.
