Honest diagnostic

Repair or replace your concrete steps?

Six questions you can answer by looking at your own steps. You'll get one of three verdicts — resurface, repair or replace — with the reasons and the ballpark cost. If the cheap option is the right one, that's what it will tell you.

Look at the tread surfaces. What do you see?

Scaling is the top skin flaking off. Spalling is deeper chunks breaking away.

Answer from what you can see — no tools beyond a hammer.

How the verdict works

The quiz weighs what you see in three buckets:

  • Surface signs — light scaling, popouts and crazing. On their own, they point to a resurface: grind off the weak skin and put down a new surface, often a quartz system.
  • Local damage — broken nosings, a few hollow spots, open but level cracks, a small gap at the house or early rust stains. These point to a repair: rebuild the edges, fill the cracks, reset a settled precast set, treat the steel.
  • Structural signs — widespread hollow sound, cracks with one side higher than the other, steps that rock or have sunk, water running toward the house, or bare rusted rebar. These point to replace, because no coating or patch fixes a failing base or delaminated concrete.

Age only tips the balance when several problems stack up on old steps. Old steps in good shape still get a “resurface” verdict.

Why we built it this way

Most step companies only sell one thing — new steps, or repairs. We do both, so we can afford to be straight with you. A resurface or repair now, done properly, keeps you happy. That’s worth more to us than a replacement you didn’t need yet.

Before you start

You’ll need good light and a hammer or something solid to tap with. Look at the treads, the front edges (nosings), the risers, and the joint where the top step or landing meets the house. Then work through the questions above.

If you’re not sure what you’re looking at, the damage dictionary below shows the eight most common types of concrete damage, what causes them and what they usually take to fix.

Damage dictionary

Name what you see on your steps

Eight common kinds of concrete damage, what causes them, and what they usually take to fix.

Scaling

Usually: resurface

What it looks like
The top skin flakes or peels off in thin patches, leaving a rough surface. Often worst where salt and meltwater sit.
Why it happens
Water in the surface freezes and expands; de-icing salts make the cycles harsher. Non-air-entrained or overworked surfaces scale first.
What it usually takes
Shallow scaling on sound concrete can be ground and resurfaced or quartz-coated.

Spalling

Usually: repair

What it looks like
Deeper chunks break away, usually at the front edge of a step (the nosing), corners, or over rusting steel.
Why it happens
Freeze-thaw damage deeper in the concrete, impact from shovels and ice chippers, or rebar rusting and expanding.
What it usually takes
Isolated spalls are rebuilt with repair mortar. Widespread spalling means replacement.

Popouts

Usually: resurface

What it looks like
Small cone-shaped pits, often with a broken piece of stone at the bottom.
Why it happens
A porous stone (aggregate) near the surface absorbs water, freezes and pops the concrete above it off.
What it usually takes
Usually cosmetic. Patch or coat if the look bothers you.

Crazing

Usually: resurface

What it looks like
A fine spider-web of hairline cracks across the surface, most visible when the concrete is drying after rain.
Why it happens
The surface dried or cooled faster than the concrete beneath it when it was first placed.
What it usually takes
Cosmetic. A penetrating sealer helps; a quartz finish hides it completely.

Delamination

Often: replace

What it looks like
Sounds hollow when tapped. The surface may lift off in sheets.
Why it happens
The top layer separated from the concrete below — common after finishing errors or repeated freezing of trapped water.
What it usually takes
Nothing bonds well to a delaminated layer. Small areas can be cut out; large areas mean new steps.

Settlement & tilt

Often: replace

What it looks like
Steps sink, lean away from the house or rock. A gap opens at the foundation wall and water runs toward the house.
Why it happens
A thin, soft or poorly compacted base, or frost moving the soil underneath.
What it usually takes
Precast steps can sometimes be lifted, re-based and reset. Poured steps that have moved usually need replacing.

Rust stains & exposed rebar

Usually: repair

What it looks like
Orange-brown streaks, or bare steel showing at edges and cracks.
Why it happens
Water and chlorides from salt reach the reinforcement. Rusting steel expands and cracks the concrete around it.
What it usually takes
Early staining can be repaired and sealed. Exposed, rusting steel over a large area means replacement.

Efflorescence

Usually: resurface

What it looks like
A white, powdery or crusty film, often near joints and the bottom of risers.
Why it happens
Water moving through the concrete carries soluble salts to the surface, where they dry out.
What it usually takes
Cosmetic. Clean it off, then look for where the water is coming from.

FAQ

Repair or replace?: common questions

How do I know if my concrete steps are unsafe?

Steps that rock, have sunk or tilted, have a large gap at the house, have loose pieces at the edges, or have uneven risers are trip and fall hazards. If a piece moves when you step on it, stop using that step and call us.

What's the difference between scaling and spalling?

Scaling is the loss of the thin surface layer — it looks like flaking or peeling. Spalling is deeper — chunks breaking away, often at the front edges or over rusting steel. Scaling on sound concrete can usually be resurfaced; spalling needs repair or, if widespread, replacement.

Why does the quiz ask about tapping the steps?

A dull, hollow sound means the surface has separated from the concrete below (delamination). Nothing bonds well to delaminated concrete, so it decides whether a coating or overlay is even possible.
