System-based quality assurance versus the carpentry model — what is the difference?

In the stair renovation market, two fundamentally different working methods operate side by side. It makes a big difference for the consumer and the commercial client which method a provider uses — even though that difference is not always immediately visible from the outside.

The carpentry model

In the traditional carpentry model, a stair finish is installed based on the expertise and experience of the individual fitter. The quality of the end result therefore depends on the person carrying out the job at that moment.

That need not be a problem — an experienced and careful fitter can deliver excellent work. But the assurance of quality is person-bound, not system-bound.

In the event of complaints or warranty issues, the question is: who is responsible? The fitter? The dealer? The manufacturer?

The system-based model

In a system-based approach, quality is embedded in the system itself. That means:

• The material has fixed, documented properties.
• Installation follows a standardised protocol.
• The installer is trained and selected for the specific system.
• Warranties are tied to the material and the installation method.
• In the event of complaints, the line of responsibility is clear: system — installer — manufacturer.

How does Omnistair work?

Omnistair works exclusively through selected installers with system training. The installation of EverStep, Signature and EverStep Solid follows a system protocol. The installer is selected and specifically trained on the Omnistair system — not just generally skilled.

More about that system training is covered under stair renovation training. Companies that want to work with the system themselves can find the steps under becoming a stair renovation dealer.

This has consequences for the warranty: the product warranty is tied to correct installation by a selected installer with system training.

Why is this relevant for clients?

For private clients: more certainty about the end result and clarity about who is accountable.

For owners' associations (VvE) and professional clients: demonstrable quality assurance is a requirement — not a wish.
