PISCINES ET SPAS POSÉIDON,
expertise that goes beyond water

Balanced water for a more enjoyable swim
Beautiful water is about more than appearance. Through precise testing and proper product dosing, our technicians maintain your pool's balance and intervene before problems take hold.
Properly balanced water generally requires fewer chemicals. The result: clear, pleasant water with fewer fluctuations that can make swimming uncomfortable.
Factors that can quickly throw your water out of balance:
- A heat wave
- A thunderstorm
- A pH imbalance
- Insufficient sanitizer
Regular visits allow us to intervene before a problem takes hold.
A water filtration system that always performs
Our technicians understand all your pool systems. The filtration system, pump and other equipment are checked to keep your pool healthy, efficient and well maintained.
Efficient filtration is the key to clean pool water:
- The baskets are cleaned;
- The filters are working properly;
- Backwashing is performed at the right time;
- Water circulation is optimal.


A pool that is always ready for your guests
No more cleaning the pool a few hours before your guests arrive.
Your pool stays clean, balanced and ready to use at all times.
Prompt action as soon as a problem is detected during one of our visits, ensuring that your pool operates properly.
Everything you need to know about our
pool maintenance service
What does a pool maintenance service include?
Depending on the selected plan, maintenance may include:
- complete water testing;
- chemical adjustments;
- cleaning the skimmer and pump baskets;
- brushing the walls and floor;
- vacuuming;
- cleaning the waterline;
- checking the filtration system;
- inspecting the equipment;
- recommendations to ensure your pool operates properly.
What are the benefits of weekly maintenance?
Regular maintenance keeps the water crystal-clear, reduces the risk of algae, extends the life of the equipment and helps prevent costly repairs. You also save time and enjoy a pool that is always ready for swimming.
Do you supply the chemicals?
Yes, we can supply the necessary products based on your needs or use those you already have. Our technicians add only the amounts required based on your water test results.
Does maintenance reduce chemical consumption?
Yes, a regularly maintained pool generally requires fewer corrective treatments than an unattended pool. By maintaining the proper water balance from the start, shock treatments, algae problems and major adjustments can often be avoided.
Do you maintain saltwater pools?
Yes, we maintain pools equipped with salt chlorine generators as well as pools using chlorine, bromine and several other sanitation systems. We also check the salt cell's operation and the settings specific to this type of installation.
Do you maintain heated pools?
Yes, during our visits we also check that the heating equipment is operating properly, whether it is a heat pump, gas heater or another system. Properly balanced water also helps protect this equipment.
Do you maintain in-ground and above-ground pools?
Yes, our technicians maintain in-ground pools, above-ground pools and a variety of residential and commercial installations. We adapt our methods to the type of pool and the installed equipment.
What happens if my water turns green?
Green water generally indicates the presence of algae or a significant water chemistry imbalance. Our technicians will perform a complete analysis to identify the cause of the problem and apply the appropriate treatment to restore clear water as quickly as possible.
How do I know if my pool needs maintenance?
Several signs may indicate that maintenance is needed:
- Cloudy water;
- Algae growth;
- Deposits on the pool floor;
- A dirty waterline;
- Less effective filtration;
- High chemical consumption;
- An unusual odour;
- Reduced equipment performance.
Regular maintenance can generally prevent these problems.
Do you check the equipment during visits?
Yes, at every visit our technicians visually inspect the pool's main equipment. This inspection often makes it possible to quickly detect a leak, unusual noise, filtration problem or early failure before a more extensive repair is needed.
Can I be away during your visit?
Yes, in most cases you do not need to be present. Our technicians perform the scheduled work and can send you a detailed report of the work completed along with any recommendations.
Do you offer one-time service or only maintenance plans?
We offer both one-time visits and regular maintenance plans. Whether you want a single visit or weekly maintenance throughout the season, we can recommend the solution best suited to your needs.
In which areas do you offer pool maintenance service?
