How do I replace crumbling concrete front steps in New Brunswick?

Replacing crumbling concrete front steps in New Brunswick is a job for a professional concrete contractor — the steps require a frost-resistant footing at 4–5 feet depth, proper forming, reinforcement, air-entrained concrete, and finishing, all within a tight working window. The good news is that new concrete steps, properly built, will last 30–50 years in NB with minimal maintenance.

Before any concrete is poured, the failed steps need to be broken up and removed. Concrete demolition is physically demanding work — a sledgehammer and rotary hammer work for small steps, but for a full set of steps with a landing (typically 1–2 cubic yards of concrete), a concrete saw and small excavator or jackhammer is much faster. Demolition of a standard front step set runs $300–$800 in NB depending on size and access.

The footing is the most critical element. NB's frost depth of 4–5 feet means any freestanding step structure needs footings that extend below the frost line. Steps that don't have frost-depth footings will heave every spring, crack, and eventually become unsafe. This is the reason so many older NB front steps are crumbling — they were built on shallow footings that have been heaving and settling for decades. Proper footing installation requires excavation 4+ feet deep, forming and pouring the footing, and waiting for the footing to cure before building the step structure above.

Forming and reinforcing the steps is skilled work. Step forms are built from 3/4-inch plywood and 2x lumber, shaped to the exact rise and run dimensions. #10M or #15M rebar is placed throughout the step mass to hold it together and prevent cracking. The forms must be plumb, level, and braced to resist the pressure of fresh concrete. A typical 4-step set with a landing uses 1.5–2.5 cubic yards of concrete — enough that a ready-mix delivery makes sense over mixing by hand.

Concrete mix specification: Use air-entrained concrete (4–7% air content) at 30–32 MPa (4,000–4,500 PSI) for front steps in NB. Steps see full freeze-thaw exposure, foot traffic, shovelling, and de-icing salt — the best mix specification pays for itself in longevity. Non-air-entrained concrete will spall within 5–10 years in NB conditions.

Finishing: Broom finish the treads for traction. Steps finished too smooth are dangerously slippery in NB winters when ice forms. Edging the step nosings gives a crisp, durable edge that resists chipping.

Apply a penetrating silane/siloxane sealer after the concrete has cured for 28 days — and reapply every 2–3 years. This is the single most effective maintenance practice for extending step life in NB.

Cost for a new set of concrete front steps in NB (3–5 steps with landing) runs $1,500–$4,000 depending on size and complexity. New Brunswick Concrete can match you with experienced step and porch contractors in Moncton, Fredericton, Saint John, Dieppe, and surrounding areas for free quotes.
