Optimize your composite deck stairs in Quebec
Technical note: Installation details vary by municipality, product line, board profile, fastening system, loads, and site conditions. Use this article as general guidance only; confirm the final design with your local building department, the manufacturer's current installation guide, and a qualified contractor or engineer when structural loads are involved.
Creating a deck in Quebec with solid stairs is a key element of your outdoor living space. Choosing the right method for cutting and installing stair stringers ensures safety and durability, especially with advanced materials like those offered by Fiberon, TimberTech, Trex, and TruNorth.
Essential tools and materials
- Circular saw: for straight cuts.
- Jigsaw: for finishes.
- Carpenter's square: for tracing step and riser angles.
- Clamps: to hold the stringer in place.
- Drill/driver and appropriate bits.
- Measuring tape and spirit level: for precise tracing.
- Treated wood or galvanized steel stringer: your stair support.
Choosing the right composite material
Brands like Fiberon, TimberTech, Trex, and TruNorth offer composite decking boards resistant to the Canadian climate's harsh weather. Depending on the frequency of use and sun exposure, choose an appropriate finish:
- Trex Boardwalk for a natural wood effect.
- TimberTech Legacy for rich, lasting color.
- Fiberon Symmetry for a non-slip surface.
- TruNorth UltraShield for maximum UV resistance.
Measurements and tracing: the foundation for a successful installation
Calculating step height and depth
To ensure comfortable climbing, use tread and riser dimensions accepted by your municipality and keep them uniform across the entire stair run. Values such as a 7-¾" (19.6 cm) maximum riser and 10" (25.4 cm) minimum tread depth are common references that must be validated with local code.
Transfer your measurements onto the stringer using a carpenter's square, aligning the 'rise & run' scale according to your calculations.
Tracing the stringer
Position the calculation ruler on your stringer and carefully trace each step. Check for regularity by placing a spirit level on each traced line.
Cutting stair stringers
Main cut
Using a circular saw, make your cuts following the lines. Always work with the saw blades under the stringer to prevent splintering. Leave a few millimeters if you plan to finish with a jigsaw.
Finishing and safety
Complete the cuts with a jigsaw for a clean result. Always wear safety glasses, gloves, and ensure the stringer is securely fastened with clamps.
Installing stairs on your composite deck
Spacing and structural support
- Stringer spacing: follow the manufacturer's stair-span table for the exact board profile; many composite stair treads require 9" to 12" O.C. support rather than 16" O.C.
- Reinforcements: add an extra stringer if your stair width exceeds 36" (91 cm).
- Intermediate platforms: essential for large elevation changes.
Appropriate fasteners
Use stainless steel screws designed for composite. Prioritize hidden fasteners compatible with Trex and patented systems from Fiberon or TimberTech. For TruNorth, follow the manufacturer's recommendations to prevent warping.

Aesthetic finishes
Cover the risers with boards that match your composite deck's surface. Play with colors (cocoa, sand, foggy dew) to create a harmonious look.
Maintenance and durability
Minimal maintenance ensures extended longevity. A simple gentle pressure wash and a mild degreaser are enough to maintain the brilliance of your stairs.
