SPC (Stone Polymer Composite) vinyl flooring has become the most popular floor covering on the South Shore, and it is hardly surprising. Waterproof, durable, easy to maintain, and with a visual appearance that mimics wood or stone perfectly, it is an option that truly makes sense for homeowners in Brossard, Longueuil, or Saint-Lambert who want a beautiful floor without the hassle.
The good news is that SPC vinyl floor installation can be done as a DIY project by a skilled homeowner. The bad news is that a poorly executed installation can cause problems: lifting, gaps between planks, or creaking noises. In this complete guide, we explain everything, step by step, to ensure your installation project on the South Shore is a success.
And if you prefer to entrust the installation to professionals, our team at Artisan Espace Design is here for you! We offer a professional installation service across the entire South Shore, from La Prairie to Saint-Lambert.
What is SPC vinyl flooring and why is it so popular on the South Shore?
SPC is an evolution of traditional luxury vinyl (LVP). Its rigid core made of a polymer and stone composite gives it exceptional dimensional stability, which is very important in the context of the Quebec climate. Unlike older flexible vinyls that could warp with temperature changes, SPC remains stable even with the significant thermal variations we experience on the South Shore between our hot summers and cold winters.
A quality SPC floor consists of 4 to 5 layers: a cork or foam base layer (for acoustic comfort), the rigid SPC core, a printed vinyl layer with the decorative pattern, and a transparent protective wear layer. It is this last layer that determines the product’s durability: for heavy residential use, a wear layer of 20 mil (0.5 mm) is the recommended minimum.
Available in classic formats (long planks mimicking wood) or tiles (for a stone or concrete effect), SPC vinyl flooring is installed as a floating floor with a click system, without glue or nails. This is why the installation is accessible to DIYers: no special equipment or specific carpentry skills are required.
Tools required to install an SPC floor on the South Shore
Before starting, ensure you have all the materials on hand. There is nothing more frustrating than starting the installation and realizing a tool is missing!
- Circular saw or miter saw (for straight and angled cuts)
- Jigsaw or hand saw (for cuts around obstacles like pipes)
- Spirit level or laser level
- Tape measure and square
- Rubber mallet and tapping block
- Pull bar (for the last row)
- Pencil or marker
- Industrial vacuum
- Knee pads (your back will thank you!)
- Spacers (minimum 8 mm for the expansion joint)
Step 1: Prepare the subfloor
Subfloor preparation is the most important step and, unfortunately, the one many DIYers neglect. A poorly prepared subfloor is a recipe for an SPC floor that creaks, warps, or shows visible irregularities.
Begin by carefully inspecting your subfloor. If it is concrete (which is often the case in South Shore basements), check that it is clean, dry, and level. A tolerance of 3 mm (1/8 in) over 2 meters (6 ft 7 in) is generally accepted. Beyond that, a self-leveling compound must be used to correct irregularities.
If it is a plywood (wood) subfloor, check that it is securely screwed down, with no planks that move or make creaking noises. Any holes or defects must be filled with wood filler before installation.
Moisture check
On the South Shore, moisture is a critical factor, especially for basements. Excess moisture in the concrete can compromise the adhesion and durability of your SPC flooring. Use a hygrometer or a calcium carbide moisture test to ensure the concrete’s moisture level is below 85% (RH). If the level is higher, a vapor barrier will be necessary.
Step 2: Acclimatization of the SPC flooring
Although SPC is less sensitive to moisture variations than wood, it is still recommended to let the flooring boxes acclimate in the room for 48 hours before installation. The room temperature should be between 18°C (64.4°F) and 27°C (80.6°F). This allows the material to adapt to the ambient temperature and humidity of your South Shore home.
Store the boxes flat or upright, without stacking them in a way that creates pressure on the planks. During acclimatization, keep the heating or air conditioning at their normal levels.
Step 3: Plan the plank layout
Before laying the first plank, take the time to plan the layout. The golden rule: the planks should be parallel to the longest wall or the main light source (usually the windows). This creates a sense of depth and visually enhances the space.
Measure the width of the room and divide it by the width of a plank to calculate the width of the last row. If this last row is less than 5 cm (2 in), reduce the width of the first row to balance both sides.
Do not forget to allow for expansion joints: minimum 8 mm (5/16 in) between the floor and all walls, door thresholds, and any fixed obstacles. Even rigid SPC needs this space to expand slightly during temperature changes.
Step 4: Starting the installation — The first row
The first row is the most important: it determines the alignment of everything else. Place the spacers against the starting wall to maintain the 8 mm (5/16 in) expansion joint, then lay the first row of planks with the tongue facing the wall.
Use the mallet and tapping block to assemble the planks without damaging the edges. To cut the last plank of a row, measure the remaining space minus 8 mm (5/16 in) for the expansion joint, mark the cut, and use the saw.
Keep the cut piece if it is longer than 30 cm (11.8 in). It will be used to start the next row, which will allow the longitudinal joints to be staggered by at least 30 cm (11.8 in) between rows.
Step 5: Installing the subsequent rows
For each row, first insert the short end of the new plank into the previous plank, then slightly tilt the plank and slide the long tongue into the groove of the previous row. A light tap with the mallet on the tapping block will lock the clips in place.
Regularly check with your level and tape measure that the rows remain straight and that the expansion joints are maintained. If you notice any drifting, correct it immediately rather than continuing and ending up with a crooked floor at the end of the room.
Stagger the longitudinal joints by at least 30 cm (11.8 in) (ideally 40 cm) between adjacent rows. This provides a more natural look and better distributes mechanical stress.
Step 6: Special cuts and obstacles
Doors, pipes, and inside or outside corners require special cuts. For pipes, drill a hole slightly larger than the pipe’s diameter (about 5 mm larger), then make a straight cut to the hole to pass the plank through. Hide the cut with a decorative finishing ring.
For door frames, use a small saw to slightly undercut the bottom of the frame so the floor can pass underneath. Slide a piece of flooring under the frame to check that the cut is sufficient.
Step 7: The last row and finishing touches
The last row is often the most delicate. Measure the remaining space, subtract 8 mm (5/16 in) for the expansion joint, and cut the planks lengthwise using your circular saw. Use the pull bar to click the last row into place without damaging the wall.
Once the installation is complete, remove all spacers. Install baseboards or quarter-round moldings to cover the expansion joints around the entire perimeter of the room. Baseboards should be fixed to the wall and not the floor, so as not to block expansion.
For transitions between rooms or between different types of coverings, use appropriate transition profiles (T-molding, reducer, or quarter-round as needed).

FAQ — SPC Vinyl Floor Installation on the South Shore
1. Is SPC vinyl flooring suitable for a basement on the South Shore?
Yes, it is actually one of the best choices for a basement. SPC is waterproof (unlike wood) and very resistant to the moisture variations common in Quebec basements. However, ensure the concrete is dry and the moisture level is acceptable before installation.
2. Is an underlayment membrane required with SPC vinyl?
Many high-end SPC floors come with a pre-installed acoustic membrane (cork or IXPE foam). If this is the case, no additional underlayment is required, as a double layer of cushioning can compromise the stability of the clips. If your floor does not have a pre-installed membrane, a thin acoustic membrane of 1 to 2 mm (0 in to 1/16 in) can be added to reduce impact noise.
3. Can SPC be installed over an old floor?
Yes, in many cases. SPC can be installed over tile (if the joints are not too deep), concrete, or plywood. It should not be installed over thick flexible vinyl flooring (more than 3 mm) or over a heated floor whose compatibility has not been verified.
4. How long does an SPC vinyl floor installation take?
For an experienced DIYer, allow about 8 to 10 hours per 100 square feet (approximately 9 m²). A standard 12 x 14-foot room can take a full day. For a professional, the time is generally reduced by half.
5. What SPC thickness do you recommend for the South Shore?
For standard residential use, a total thickness of 6 mm (1/4 in) with a 20 mil wear layer is a good minimum. For high-traffic areas or homes with pets, aim for 8 mm (5/16 in) total thickness and a 28 mil wear layer. For the basement, the presence of an integrated acoustic membrane is a plus.
6. Is SPC flooring compatible with radiant floor heating?
Yes, provided you choose a product certified for radiant heating. Ensure the maximum floor temperature does not exceed 27-28°C (80.6°F to 82.4°F) (according to the manufacturer’s recommendations). Our range at AED includes several SPC products compatible with both hydronic and electric systems.
7. How do you clean an SPC vinyl floor after installation?
Wait at least 24 hours before the first cleaning. Use a vacuum or broom to remove cutting dust, then a damp mop (wrung out, not soaking) with a neutral cleaner. Avoid abrasive products, waxes, and steam cleaners that can damage the wear layer.
8. Can SPC be installed diagonally?
Technically yes, but it is an advanced technique that generates many cuts and material waste (up to 20% extra). Diagonal installation is rarely recommended for a first DIY project. If you want a different visual effect, consult our team at AED instead.
9. How many boxes of flooring should I buy?
Calculate the room’s area (length x width in square feet), then add 10% for cuts and waste. If your room has many angles or if you are installing diagonally, increase this to 15%. SPC flooring is generally sold in boxes of 20 to 25 square feet.
10. Can a damaged SPC plank be repaired after installation?
Yes, and this is one of the great advantages of floating installation. Unlike glued or nailed flooring, a damaged SPC plank can be removed and replaced without dismantling everything. Simply disassemble the planks up to the damaged one, replace it, and reassemble. This is why it is always recommended to keep a few extra planks after installation.
11. What is the lifespan of a quality SPC vinyl floor?
A good quality SPC floor (wear layer of 20 mil and above) can last between 15 and 25 years in normal residential use. The lifespan depends mainly on the quality of the wear layer, regular maintenance, and usage (number of people, presence of pets, etc.). The manufacturer’s warranty is a good indicator: look for at least 25 years for residential use.
12. What is the average cost of installing an SPC vinyl floor on the South Shore in 2026?
In 2026, the professional installation cost for an SPC vinyl floor on the South Shore varies between $2 and $4 per square foot (labor only), depending on the room’s complexity and the required preparation. The total cost (materials + installation) is generally between $6 and $12 per square foot for intermediate to high-end SPC flooring.
