An exterior spiral stair needs a galvanized or powder-coated finish rated for full winter exposure; an interior one only needs to look good, which opens up more finish options.
A prefabricated spiral staircase kit typically starts around $3,500, while a fully custom spiral built to a non-standard diameter or an exterior-rated finish can run $18,000 or more depending on rise and material.
Metal spiral kits sized to a standard diameter and rise, the most budget-friendly option.
A fully custom spiral built to a specific diameter, rise and finish where a standard kit doesn't fit.
Wood treads over a metal frame for a warmer interior look than an all-metal kit.
Galvanized or powder-coated steel for an exterior deck-access spiral stair.
Whether a standard prefabricated kit fits or you need a fully custom diameter, we install both.
We size spiral stairs to genuinely tight footprints without cutting corners on tread depth or headroom.
Loft access, deck access, or a feature interior stair – one crew for all of them.
Available floor space and total rise determine whether a standard kit fits or a custom build is needed.
Kits are ordered to spec; fully custom spirals are fabricated to the exact measured rise and diameter.
The centre column is set plumb first, then treads and railing are installed and checked for level.
We test every tread for level and secure fastening before calling the job done.

It depends on code and comfort – a very tight diameter is possible for occasional-use access, while a primary staircase needs more room; we'll confirm what fits your space and use case.
Yes, a standard kit is usually the more budget-friendly option when your space matches an available standard diameter and rise.
