Why existing concrete stairs are often retained

When a stairwell becomes dated, many residents assume that full replacement is the only option. In practice, that is often not necessary.

In many apartment complexes, gallery flats and residential buildings, the concrete stair structure remains technically usable for years. The surface may be worn, but the load-bearing structure is often still in good condition.

The broader set of requirements for owners' associations (VvE) and commercial stairwells is found in stair renovation for owners' associations and commercial buildings.

Short answer

Existing concrete stairs are often retained because the structure can usually last for decades. By renovating the existing base instead of replacing it entirely, costs, disruption, project duration and waste streams can often be reduced considerably.

Why concrete often lasts longer than people think

A concrete staircase is a structural part of the building. When there is no serious damage, concrete can keep functioning for decades.

Common problems relate to wear of the walking surface, damaged finishes, a dated appearance, soiling and insufficient grip. These problems do not automatically mean that the structure itself needs replacing.

How such a concrete tread is then renewed is found in renovating prefab concrete VvE stairs.

The difference between structure and finish

In renovations it is important to distinguish between structure — the load-bearing element — and finish — the layer that provides appearance, grip and ease of use.

In many buildings it is precisely the finish that is dated while the structure is still fully usable. This can make renovation more attractive than full replacement.

The finish determines not only appearance and grip but also fire behaviour; why that matters is found in why fire classification matters in a VvE stairwell.

Why full replacement is often invasive

Removing an existing concrete staircase has major consequences: demolition work, noise nuisance, dust, logistical challenges, a longer project duration and higher costs. For apartment complexes this means additional disruption for residents.

That is why most projects first investigate whether renovation is possible.

Why renovation fits within a long-term maintenance plan (MJOP)

A long-term maintenance plan (MJOP) looks at the lifespan of building components. When the existing concrete structure is still sound, renovation offers clear advantages: lower investment costs, less disruption for residents, shorter execution and a more efficient use of maintenance budgets.

What postponing maintenance ultimately costs is found in what postponing stair maintenance costs in an apartment building.

Why build-up height is a point of attention

When renovating existing stairs, the stair geometry plays an important role. Riser heights, going, landing connections and existing detailing are all considered. Particularly in older apartment complexes, a limited build-up height is a relevant starting point.

EverStep Solid by Omnistair is 4.3 mm thick — in most cases the system fits directly over the existing tread without dimensional adjustments.

Why sustainability increasingly plays a role

Retaining existing structures aligns with a broader movement in the construction sector: reuse, material savings, a reduction in demolition waste and extending lifespan. When a concrete structure still functions well, renovation contributes to these goals.
