A professional closing in Kennewick typically runs $325–$600 and a spring opening $275–$500; many companies discount the pair booked together:
| Job | Typical Kennewick price |
|---|---|
| Fall closing / winterization | $325–$600 |
| Spring opening | $275–$500 |
| Opening + closing package | $550–$1,050 |
| Startup chemicals (opening) | $85–$165 |
| Cover removal, cleaning and storage | $110–$220 |
| Winter cover install (existing cover) | $85–$220 |
| New safety cover, measured and installed | $1,800–$4,200 |
Washington rates are above the national baseline used for these estimates, mainly on labor and permitting. Price moves with pool size, the number of lines to blow out, a spa or water feature, a heater and an in-floor cleaning system — and whether the company clears a green opening or charges separately for the algae recovery.
A sagging cover holding rain and leaves is the most common winter problem. A cover pump and a quick look after storms prevents a green spring.

Westside pools fight organic debris — fir needles are a skimmer's nemesis — through a season that rewards automatic covers; eastside pools run a hotter, dustier, more evaporative summer. Both ends close properly for freezing winters. West of the Cascades expect a mid-June-to-September window with mild, gray shoulders — heat pumps and solar covers are what make the investment rational. East of the mountains, summers hit 95°+ and the season stretches noticeably longer.

DIY closings save the service fee but need an air compressor or shop vac strong enough to clear the lines, the right plugs and a careful hand with the heater. One missed line that freezes can cost more than a decade of professional closings. Many owners split it: a pro blows out and plugs the lines, and the owner handles the cover and spring cleaning.

Close when daytime water temperature stays below about 60–65°F but before the first hard freeze — typically late September through October in Kennewick. Closing too early while the water is warm invites algae under the cover; closing too late risks a freeze in the equipment.

Both ends close properly for freezing winters.
Open once nights stay above freezing and the water is around 60°F or warmer — late April into May for most of Kennewick. Opening early costs a little more in heating and chemicals but prevents the algae bloom that turns a late opening into a green-to-clean job. Book ahead: openings cluster into the same few weeks.
A full winterization balances and treats the water, lowers the level below the skimmer or returns, blows out and plugs every suction and return line, adds pool antifreeze where lines cannot be fully cleared, drains the pump, filter, heater, chlorinator and salt cell, removes and stores drain plugs and fittings, and installs the cover with a cover pump. Ask for the checklist in writing and keep it with your equipment records.

In freezing climates, yes: lower the water below the return, remove or winterize the pump and filter, add a winter chemical kit and an air pillow under the cover to relieve ice pressure on the walls. Many service companies handle above-ground closings for less than an inground closing; the guides on PoolPad cover the DIY version step by step.
Water expanding in the plumbing and equipment cracks pump housings, filter tanks, heater exchangers and above-ground pipe — repairs that run from a few hundred dollars for a pump lid to several thousand for a heater. If a freeze is coming and the pool is still open, keep the pump running continuously; moving water resists freezing and most automation systems have a freeze-protect mode for exactly this.
