Installation
The complete guide to above-ground pool installation
Installing an above-ground pool is one of the best investments for enjoying summer with your family, without the cost of an in-ground pool. But a successful above-ground pool installation relies on rigorous site preparation and careful attention to several technical steps. Here is our complete guide, built on industry best practices for a successful project across Montreal's South Shore and Montérégie.
Step 1: choosing the ideal location
First, you need to select a flat, clear, and sufficiently sunny location. Avoid areas under trees (falling leaves and branches) and make sure to respect the minimum distances from property lines required by your municipality. A permit application is often necessary — our team can guide you through this administrative process.
Step 2: choosing the shape and size
Above-ground pools come in two main shapes:
- Round — economical, quick to install, ideal for small to medium yards (12 to 27 feet in diameter)
- Oval — more swimming surface, perfect for active families (12x15 to 12x21 foot formats)
The choice depends on the space available in your yard, your budget, and the intended use. Our article on how to choose the right pool size covers this topic in more depth.
Step 3: site preparation
This is the most critical step for the durability of your pool. The ground must be:
- Excavated and leveled precisely (a deviation of more than 1 inch can compromise the structure)
- Covered with a compacted sand base for a smooth, stable surface
- Free of rocks, roots or debris that could puncture the liner
In several South Shore municipalities, clay soils require special attention to drainage to avoid water accumulating under the structure after heavy rain.
Step 4: assembling the structure
Once the ground is ready, the metal structure (walls, uprights and top rail) is assembled according to manufacturer specifications. This step requires precision to ensure the pool is perfectly round or oval, without deformation.
Step 5: installing the liner and filling
The new liner is then installed inside the structure, adjusted to remove wrinkles, and the pool is filled gradually. Completely filling a standard pool generally takes between 12 and 24 hours, depending on available water flow.
Step 6: essential accessories
A functional pool needs an adequate filtration system. Here are the most common accessories to add right at installation:
- Filtration pump — ensures continuous water circulation
- Filter — traps impurities for clear, healthy water
- Heat pump — efficiently heats the water and extends the swimming season by several weeks
How long does installation take?
For a standard round pool, complete installation (excavation, structure, liner) generally takes one to two working days, excluding fill time. Larger oval pools may require an extra day depending on site complexity.
What does installation cost?
At Piscine Rive Sud, a round pool installation starts at $2,500 for a 12-foot diameter and reaches $5,000 for 27 feet. Oval models, offering more surface area, start at $5,100 for a 12x15 format and go up to $5,600 for 12x21. These prices include the structure, liner and labor; accessories such as the pump, filter or heat pump are added based on your needs.
Tip: plan your installation in spring to enjoy your pool from the start of summer and avoid high-season delays.
