How to Install a Spiral Staircase

Stair Installation Made Simple

Your Salter Spiral Stair will arrive on location in an easy to assemble kit. Each Salter Spiral Stair product type requires a slightly different installation method and we offer a detailed set of easy to follow instructions for each product line below. You will never miss a step, no matter which product you purchase.

Indoor Foundations

If your spiral stair will be indoors then it’s highly unlikely that you’ll have to make any adjustments to your floor space before installing your spiral stair.

One location where you may consider making adjustments is if your stair will be on a concrete floor in the basement.

The concrete will be more than stable enough. But it may have some cracks or crumbling in it due to age and maybe even water flow through some storm doors and across the slope of the floor toward the sub pump. Especially if it’s an older house with an unfinished basement.

If this is the case then taking the time to fill these cracks with a quick concrete mix and trowel job should be sufficient. Let the concrete repairs cure then install as planned.

Experience Required and Minimal Tools Needed

Not everyone has a construction background, so DIY projects should reflect that. We incorporate this knowledge into our stair build system. Any two average homeowners with zero background in construction can assemble our spiral stairs in the course of a weekend and move on to the next stage of a home project with ease. Better yet, this assembly can be done with a minimum of standard tools. Absolutely no specialty tools are required. So you’re already equipped to handle this project and have no further expenditures to worry about.
