How do I build concrete porch steps with a landing in NB?

Building concrete porch steps with a landing in New Brunswick is a multi-phase project that requires frost-depth footings, careful forming, air-entrained concrete, and proper reinforcement — it's one of the more complex flatwork jobs for a residential contractor and is generally not a DIY project given the structural requirements and volume of concrete involved. Here's what the process looks like from start to finish.

Phase 1 — Planning and permits. Determine your total rise (the vertical distance from finished grade to the porch floor level), then divide by your desired rise per step (7 inches is standard) to get the number of steps. A landing — the flat platform at the top or an intermediate level — should be at least 36 inches deep in the direction of travel and as wide as the doorway plus clearance on both sides (minimum 36 inches wide; 48 inches or wider is more comfortable). Check with your local building office in Moncton, Fredericton, or Saint John — some municipalities require a permit for steps over a certain size, particularly if they're connected to the house.

Phase 2 — Excavation and footings. Excavate below the step and landing footprint to frost depth — 4 feet minimum in southern NB, 4.5–5 feet in northern NB. The footing can be formed as either sonotube pier footings (12-inch diameter minimum) or a continuous perimeter footing wall. Pour the footings with 25–30 MPa concrete and allow to cure for at least 7 days before building the step structure above.

Phase 3 — Building the form work. Forms define the shape of the steps and landing. Use 3/4-inch plywood for the risers (the vertical face of each step) and 2x8 or 2x10 lumber for the sides. Each riser form must be positioned precisely at the correct rise height and well braced — fresh concrete exerts significant hydraulic pressure on forms, especially for a mass with a landing. The landing form is essentially a flat box at the top of the structure. Apply form release oil to all form surfaces before pouring.

Phase 4 — Reinforcement. Place #10M rebar throughout the step and landing mass, typically in a grid pattern at 12-inch centres horizontally and vertically. Maintain a minimum 1.5-inch cover from the concrete surface to the nearest rebar. Tie the rebar grid to the footing rebar for structural continuity. Steps without reinforcement will eventually crack into pieces; reinforcement holds the structure together even after cracking occurs.

Phase 5 — The pour. Order air-entrained 30–32 MPa ready-mix concrete. A typical 4-step set with a 3x4-foot landing uses approximately 1.5–2.5 cubic yards. Pour the steps from the bottom up, consolidating each section with a vibrator or rod to remove voids. Finish treads with a broom texture (front-to-back strokes for good traction), and slope each tread forward 1–2% for drainage.

Phase 6 — Curing and sealing. Cover with plastic or curing compound for 7 days minimum. After 28 days, apply a penetrating silane/siloxane sealer.

Cost for steps with a landing in NB runs $2,000–$5,000 installed. New Brunswick Concrete can match you with experienced porch and step contractors for free quotes in your area.
