A carefully performed spa closing before the first freeze
We recommend booking your spa closing early in the fall to secure a service date before the first periods of freezing weather.
Certain signs indicate that it is time to start thinking about winterizing your spa:
- Nighttime temperatures are approaching 0 °C.
- You do not plan to use your spa again before spring.
- The first periods of freezing weather are in the forecast.
- You are leaving for several months.
- Your home will be unoccupied during the winter.
Our technicians handle the main steps involved in winterizing your spa, from draining it to preparing the plumbing and equipment.
Even a small amount of water left in the plumbing, jets or pumps can freeze and expand during the winter, potentially damaging certain components. A properly performed closing protects your spa and makes it easier to reopen in the spring.

Why is it essential to close your spa properly for the winter?
Quebec winters are hard on spas. Water left in the plumbing and equipment can freeze, expand and damage costly components.
A professional closing protects your investment by ensuring that the plumbing is completely drained and the equipment is prepared and secured for winter temperatures.
The cost of a closing is generally minimal compared with the repairs that freezing can cause.


Essential winter protection: THE FOAM BLOCK AND PROTECTIVE COVER
The foam block installed in the spa helps the cover support the weight of the snow during winter. The opaque cover helps limit water infiltration through the seams of the spa cover.
For adequate protection, it is important to keep these items in place throughout the cold season.
Piscines et Spas Poséidon cannot guarantee the closing if the recommended foam block and protective cover are not installed, as water infiltration could damage the spa plumbing.
How should you protect your spa during the winter?
Even after closing, a few precautions are necessary to keep your spa in good condition:
- Regularly remove snow that has accumulated on the cover
- Use a snow broom rather than a sharp object
- Make sure the protective cover remains securely in place
- Never walk on the spa cover
- Do not attempt to break any ice on the spa
- Monitor the condition of the spa cover and protective cover during the winter
- Store accessories in a dry, accessible location
- Store chemicals in a cool location protected from the elements
- Clean and store the filter cartridges until the next season
Contact our team if you hear a noise coming from the spa, if ice appears to be forming inside or if the cover seems to be sagging.

Everything you need to know about our spa closing service
Why should you have your spa closed by a professional?
An improperly performed spa closing can cause water in the plumbing, pumps or heater to freeze, resulting in extensive damage and costly repairs. A technician has the equipment required to completely blow out the water lines, eliminate all traces of moisture and prepare the spa to safely withstand the winter.
When is the best time to close your spa?
We recommend closing your spa before the first significant freeze. Ideally, the closing should be performed while temperatures remain above 0 °C to prevent the water in the plumbing from beginning to freeze during the work.
What does a spa closing service include?
Depending on your installation, our service may include:
- safely shutting off the electrical power;
- completely draining the spa;
- blowing out all the plumbing;
- drying the pumps and equipment;
- cleaning or storing the filter cartridges;
- installing winter protection;
- a general inspection of the spa before winter.
Our goal is to ensure that no water remains in components that could be damaged by freezing.
Do I need to be present during the closing?
No. In most cases, you do not need to be present. If access to the spa has been arranged and we have received all the necessary information, our technicians can perform the closing and send you a report once the work is complete. This flexibility is one of the benefits of our service.
How long does a spa closing take?
The duration varies depending on the model, the location of the spa and the complexity of the installation. For most residential spas, a complete closing is performed in less than two hours.
Do you close all brands of spas?
Yes. Our technicians work on most major spa brands sold in Quebec, whether it is a residential spa, a swim spa or an in-ground spa.
My spa is installed in a gazebo or indoors. Is that possible?
Yes. We also close spas installed in a gazebo, under a shelter, inside a building or in more confined spaces. Our team adapts its work method to your installation.
Should I remove the filter cartridges?
Yes. We recommend removing the cartridges, cleaning them thoroughly and then storing them in a dry location during the winter. This extends their service life and makes it easier to reopen the spa in the spring.
Can I simply drain my spa without blowing out the plumbing?
No. Even after draining, several litres of water can remain in the lines, pumps, heater and jets. If this water freezes, it can crack the plumbing or damage spa components. Completely blowing out the plumbing is an essential step in a professional closing.
Should I turn off the electricity to my spa during the winter?
Yes. Once the closing is complete, the electrical power must remain off until the spa is reopened in the spring. This prevents any equipment from attempting to operate while the spa is empty.
What happens if snow accumulates on the cover?
We recommend regularly removing heavy snow accumulation to reduce the weight on the cover. Use a snow broom rather than a metal object that could damage the vinyl. It is also important never to walk on the spa cover.
What should I do if I notice ice or an unusual noise during the winter?
Contact our team promptly.
Ice inside the spa, a noise coming from the equipment or a cover that appears to be sagging may indicate a problem requiring attention before significant damage occurs.
Does closing protect my spa against all winter damage?
A professional closing considerably reduces the risks associated with freezing, but it is still important for the winter protection to remain securely in place throughout the season and for the spa to be visually inspected from time to time.
Why install a foam block and a winter cover?
The foam block helps support the spa cover and limit water infiltration that could reach the shell. An opaque winter cover also protects the spa cover against the elements, UV rays and snow accumulation. Together, these protections help reduce the risk of damage during the winter.
When should I schedule my spa opening in the spring?
We recommend scheduling the opening as soon as temperatures are mild enough and you want to start using your spa again. Booking early generally allows you to secure the date that suits you best.
What are the risks of an improperly performed spa closing?
An incomplete closing can cause several problems, including:
• pipes cracked by freezing;
• a damaged pump;
• a cracked heater;
• broken manifolds;
• burst jets;
• damaged valves;
• water infiltration;
• complete replacement of certain components.
In many cases, these repairs can cost hundreds or even thousands of dollars.
