Pool Opening Service

Opening your pool involves much more than removing the winter cover. After months of cold weather, your pool equipment, plumbing, and circulation system need to be professionally inspected, prepared, and restarted to ensure safe, reliable operation throughout the swimming season.

Since 2002, Ultimate Pool Service has provided professional pool opening services throughout Oakville, Burlington, and Mississauga, helping homeowners start the season with confidence.

Our Pool Opening Services

This service is typically completed over two business days. On the first day, we remove the winter cover and prepare the pool for start-up. On the second business day, one of our experienced senior service technicians completes the equipment preparation, start-up, and testing to ensure all technical aspects of the pool opening are performed safely and correctly. 

Equipment Start-Up Service

Equipment Start-Up Service

Testimonials From Our Clients

Been dealing with Ultimate Pool Service for a few years now. They were instrumental in getting our pool renovated with new liner, pump, etc. Here's where it gets really good. My employer closed their operations in Eastern Canada in May, leaving me scrambling. To minimize short term expenses I had to take over the weekly maintenance. The response from Ultimate Pool Service was 100% supportive. Since then I've learned that the weekly maintenance is tougher than it looks AND Ultimate Pool Services had been very responsive and helpful ( thanks Brian ) when I'm in over my head. Did I say THANK YOU Brian and Grant

Derek Fournier

A team I can always count on! Very happy with Ultimate! I’ve opened and closed with them for a few years now and am always impressed with the great service. The staff is always friendly, knowledgeable and professional. You can count on them to get the job done! Thanks, Brian, Grant, Sarah, and team!

Jacq Steele

Very impressed with Ultimate. Called because we were having suction issues and couldn't vacuum the pool. Someone was at our house within an hour and we discovered it was one of the owners of the business. He was extremely professional and helpful, and because he was already there and fixed the issue so quickly he did some liner pulls as well for us. Now the pool is working perfectly and looking great. Thanks Brian! We will for sure be calling Ultimate again.

David Locke

We've been using Ultimate Pool for pool maintenance for several years now. Very knowledgeable and dependable. Brian is very prompt to return voicemail messages and really knows his stuff. They always come when scheduled. Helped trouble-shoot and repaired several problems.

Frequently Asked Questions

Find answers to common questions about pool opening services.

What's included in a pool opening service?

The services included depend on the package you choose. A Full Pool Opening includes winter cover removal and cleaning, while both opening options include equipment preparation, start-up and testing, installation of return fittings and accessories, and circulation system start-up by an experienced senior service technician. 

What's the difference between Full Pool Opening and Equipment Start-Up?

Full Pool Opening includes the removal and cleaning of winter cover. Equipment Start-Up is designed for homeowners who remove their own cover but want an experienced senior service technician to prepare, start, and test the pool equipment. 

When should I schedule my pool opening?

We recommend scheduling your pool opening approximately two weeks before you plan to begin swimming. This provides time for the pool to circulate, clear, and be professionally balanced, while also allowing time to address any unexpected equipment repairs or water quality issues before you plan to use the pool.

Booking early also provides the greatest selection of appointment dates during our busiest spring season.

Do I need to be home during the service?

In most cases, no. As long as technicians have access to the pool area, equipment, and a water source, service can be completed without the homeowner present.

Why isn't my pool clear immediately after opening?

Cloudy or discoloured water after a pool opening is normal. How quickly your pool clears depends on several factors, including how long the pool has been closed, the type of winter cover used, and the condition of the water when the pool was closed in the fall.

Once the pool is circulating, properly filtered, and the water chemistry has been balanced, most pools will gradually become clear within 24-48 hours. Pools with heavier debris, poor water chemistry, or algae growth may require additional cleaning, balancing, or vacuuming before they are fully swim-ready.

Should I schedule maintenance after my pool opening?

Professional weekly pool maintenance helps keep your water clean, balanced, and ready to enjoy throughout the swimming season. It also includes routine cleaning, visual equipment inspections, and professional water testing to help maintain proper water chemistry. 

How long does a pool opening take?

A Full Pool Opening is typically completed over two business days. The first visit focuses on removing the cover and cleaning the area around the pool, while the second visit is completed by an experienced senior service technician who performs the equipment preparation, start-up, and testing.

Why doesn't Ultimate Pool Service start my heater?

For safety and regulatory compliance, pool heaters should only be started and serviced by a licensed gas technician. After your pool opening has been completed, we'll provide the contact information for licensed gas fitters who can safely start and inspect your heater.
