We re-use your existing spaces
We pull the wood spindles and re-drill your existing spaces on your Bethlehem stair so the iron sets into the holes you already have — no new layout.

An iron baluster swap pulls the dated wood spindles from your Bethlehem stair, re-drills on your existing spaces, and sets the new iron in construction adhesive — handrail, newels, and treads untouched, usable that evening. On a typical SteelStacks new-build or north-side single-flight stair that's one day with very little mess, about $2,000–$3,000.

Bethlehem's SteelStacks-era south-side homes were almost all built with builder-grade wood spindles that owners now want to update to iron without a full rebuild. Because the railing geometry stays put, the swap is the lowest-disruption way to do it.

Modern White Oak project — wood pickets swapped for single-pattern satin-black iron in the existing spaces, under a natural white-oak handrail. The exact low-disruption swap Bethlehem SteelStacks owners ask for.
View this projectMost Bethlehem single-flight swaps run about $2,000–$3,000, driven by the pattern and run. A straight SteelStacks new-build run in plain square iron sits near the low end; an ornamental pattern with a balcony run trends higher. That's a range to set expectations, not a quote — we'll give you a firm number after we measure.
No. Your handrail, newels, and treads stay in place — we only pull the wood spindles and re-drill on your existing spaces for iron. That's what keeps it a one-day swap with very little mess rather than a rebuild.
One day, with very little mess. We pull the wood balusters, re-drill the existing spaces, and set the iron in construction adhesive — usable that evening. Material lead time after your measure is about two weeks.
Yes. We set the iron so the spacing satisfies the IRC 4-inch-sphere guard requirement — often tighter and safer than the original wide-set wood spindles in older Bethlehem stairs.
Yes — square-stock iron in satin black or oil-rubbed bronze is the most-picked pattern for the south-side transitional look. We bring samples to hold against your handrail so the pattern suits the open-plan room.
