We serve Salt Lake City and surrounding communities including Herriman and Riverton. Our technicians are background-checked and rigorously trained, and our proprietary technology keeps you informed of your pool’s condition and service status throughout the process.

When to Close Your Pool in Salt Lake City

There’s no single date on the calendar that signals it’s time to close. The right indicator is water temperature: once it drops below 65°F, algae growth slows significantly, and the risk of freeze damage to plumbing and equipment rises. In the Salt Lake City area, that shift typically happens in September or October, though it varies year to year.

A few practical signs to watch: overnight temperatures consistently dipping toward freezing, falling leaves piling up around your skimmer, and water that’s just too cold to use. Closing at the right time helps protect your equipment and can make your spring opening smoother. Closing too late can mean cracked pipes and a much bigger repair bill before your first swim of the season.

What Our Pool Closing Service Includes

We offer customizable pool closing plans built around your pool and your schedule. Whether you want us to manage the entire process or handle just the most technically demanding steps, we work with you to help make sure nothing gets missed.

Our closing process covers five core steps:

• Removing all debris from the pool’s water, filter, and skimmer so nothing is left to decompose or clog equipment over the winter
• Readjusting the water level to account for ice expansion and help prevent overflow from winter precipitation
• Testing water and adding chemicals for the winter (like algicide) to help keep pH, alkalinity, calcium hardness, and chlorine balanced during the off-season
• Draining equipment of excess water to prevent freezing, including pumps, filters, and heaters where applicable
• Inspecting and installing a winter cover to keep debris out and help protect pool surfaces through the cold months

Proper water chemistry at closing does the work that active filtration normally handles. Balanced water come spring can mean less cleanup, fewer chemical corrections, and a faster path back to swimming.

What Happens Without a Proper Pool Closing

Skipping professional pool closing or rushing through the steps can lead to real damage over a Utah winter. Freezing temperatures can crack plumbing lines and cause pumps and filters to fail. Vinyl liners may separate as water expands and contracts through freeze-thaw cycles.

Salt Lake City’s water is notably mineral-heavy. Without balanced chemistry at closing, calcium and scale deposits can build up on pool surfaces over the off-season, and debris left in the water promotes algae growth. Both problems can make for a harder, more expensive opening in spring. In some cases, an improperly closed pool may need equipment repairs or replacement before it’s usable the following season.

Frequently Asked Questions

What Chlorine Level Should My Pool Have at Closing?

Your pool water should have a chlorine level of 1–3 ppm and a pH of 7.2 to 7.6 at closing. These ranges help keep the water clean and balanced through the off-season without active filtration running.

Should I Shock My Pool Before Closing?

Yes. Shocking the pool a few days before closing helps eliminate bacteria and contaminants before the water sits for the winter. Just make sure chlorine levels return to the normal range before the pool is closed.

Does the Pool Need to Be Cleaned Before Closing?

Always. Debris left in the water over the off-season breaks down and feeds algae growth. Cleaning before closing is one of the most important steps in protecting water quality and helping make your spring opening easier.

Can I Close My Pool Without Professional Help?

It’s possible to close a pool independently, but the process has several steps that require the right tools, chemicals, and sequencing. A professional pool closing service reduces the risk of missed steps that lead to freeze damage or a difficult spring opening. Our team brings everything needed and helps make sure every step is done correctly.
