Gatineau Concrete Step Repair Without Full Replacement
Treads settle. Edges spall from winter salt. Risers crack. Not every problem means tearing out the whole flight. We assess each step individually, lift what is salvageable, patch what can be bonded, and replace only the concrete that has truly failed. The result is a safe, usable flight at a fraction of new-construction cost.
A full flight replacement is a major undertaking. A targeted repair is not. By examining each tread, riser and edge individually, we address only the concrete that is actually failing. One tread has settled out of plane, so we lift it. An edge has spalled, so we patch it. A single riser is cracked through, so we replace that section. The rest of the flight stays intact.
The key is honest assessment. If the whole flight has heaved off its footing, if the original rise and run violate code, or if the concrete is failing across most treads, then repair is just delaying the inevitable. In those cases, we recommend new entry steps or a complete staircase pour instead of chasing repairs that will not hold.
This same logic applies to our sidewalk and walkway repair work, where fixing only what is broken keeps costs down and results in a durable concrete surface.

How Step Repair Gets Done in Gatineau
Inspect each tread
We examine the entire flight, noting settlement, spalling, cracks, edge chips and surface wear. Each tread gets classified as repairable in place, liftable, patchable, or requiring replacement.
Lift settled treads
Where the concrete body is sound but the tread has sunk, slab-jacking raises it back to the correct elevation, restoring consistent rise and run across the flight.
Bond repair patches
Spalled noses, chipped edges and surface damage are patched with a compatible bonded mortar that matches color and restores the original profile and safety.
Pour replacement treads
Treads that are cracked through, missing support or beyond repair are cut out and re-poured to match the surrounding flight in rise, run, finish and color.
Knowing when to stop
When Repair Is Not the Right Answer
Repair works when failures are isolated, the substructure is sound, and the original rise and run meet code. It fails when the whole flight has shifted, the rise and run are non-code, or the footing was installed above the frost line and heaves every winter.
On every site visit we tell you which situation you are in. If repair is just throwing money at a doomed flight, the written quote will recommend new front entry steps or a fresh staircase instead. That honesty saves you time and money.
Lifting treads, patching edges, sectional replacement and when a flight has to come out entirely.
Yes, often. We saw-cut around the failing tread, remove it cleanly, and pour a new tread to match the surrounding rise/run, finish and color. The repair is visible but the flight is safe and working at a fraction of full-replacement cost.
A bonded repair mortar that matches color is applied to the spalled edge, finished to the original profile, and protected through cure. Done right, the patch lasts as long as the surrounding step; done wrong it pops off in a season. We do it the right way.
Often, where the step body itself is sound. Slab-jacking lifts a settled but otherwise intact tread back to its original elevation, restoring even rise across the flight. Where the tread is also cracked, sectional replacement is the better call.
When the rise/run is non-code, when the footing is wrong (steps heaving every winter), or when most treads have failed. In those cases, repairs chase the same problem forever. A fresh flight is the honest answer; the quote will say so.
Most step repairs are a half-day to a day per visit; tread replacements that include cure time stretch across two days. The schedule is in the written quote so you can plan around the temporary loss of access.
One tread had cracked through, the rest were fine. They replaced just that one, matched the rest, and the flight is safe and even again. Far less than a full replacement.

Edge spalling from road salt on three risers. Patched with matching mortar, bonded properly, holding through the next winter. Looks intentional now.

Settled tread lifted back to grade. Took half a day, cost a fraction of replacement, and the rise across the flight is consistent again. Smart fix.

Honest assessment that the whole flight was past repair and a new pour was the right call. Could have charged me for patches that would have failed. Trust earned.
