Our Pool Closing Checklist

- Add antifreeze to lines where needed
- Remove and store accessories, ladders, and rails

Why Proper Closing Matters
Connecticut winters can push temperatures well below freezing for weeks at a time. Water left in pipes, pump housings, or filter tanks expands when it freezes — cracking PVC fittings, splitting pump volutes, and fracturing filter tanks. A single freeze event can produce $1,000–$3,000 in equipment damage that a thorough closing would have prevented entirely.
Our closing technicians follow a documented procedure for every visit. They don’t leave until every return line has been blown clear, every piece of equipment is fully drained, and the winter cover is taut and anchored. We also photograph the closed equipment and send the images to you so you have a record of what was done and how everything looked going into winter.
Protecting Your Equipment
Frozen water in pool equipment is one of the most costly repairs a pool owner faces. Heat exchangers in gas and heat-pump heaters are especially vulnerable — a single freeze can crack a manifold that costs $800 or more to replace. Our technicians purge every heat exchanger port and verify the drain valve is fully open before leaving the site.
We also inspect your safety cover during closing. A cover installed with fraying straps or loose anchors is a liability risk through the winter. If we find anything concerning, we’ll tell you and can usually address it on the same visit.
When to Close Your Pool in Connecticut
The ideal closing window in Fairfield County is mid-October to early November, once water temperatures consistently drop below 60°F. Closing while the water is still warm invites algae growth under the cover. Closing too late risks a freeze event before your equipment is fully drained. We monitor local forecasts and are happy to advise on timing if you’re unsure.
Frequently Asked Questions
How long does a pool closing take? Most residential pools take 2–3 hours. Larger pools with heaters, automation systems, or attached spas may take longer.
Do I need to be home? No — as long as we have access to the pool and equipment pad, we can close while you’re away. We’ll send a confirmation with photos when we’re finished.
Can you close an above-ground pool? Yes. We service both in-ground and above-ground pools throughout Fairfield County and Westchester County.
What if it freezes before my closing appointment? Call us immediately. A single light frost typically isn’t enough to cause damage if the pool is still full of water, but an overnight hard freeze can be. We’ll assess urgency and prioritize accordingly.
We close pools from September through November. Our October schedule fills quickly — book early to guarantee your preferred date.
