Brownstone Stair Rebuild

Many of the staircases we encounter all suffer from similar problems: sagging supports, cut spindles, and delicate (and often broken) railings. This staircase had all these problems and then some, and required a complete rebuild.

Before After Painted

Because the staircase had previously been repaired with inferior materials, we tore the entire staircase out and started from scratch. The pine risers and treads were replaced with mahogany ones that were fabricated entirely onsite.

Woden Beam Steel Beam

The wooden beam beneath the stairs was completely broken. We bolted it back together and also installed a steel beam to stabilize the entire staircase.

Curved risers Curved treads

A unique feature of this staircase was that the bottoms steps each had a slight curve to it. To achieve this curve, the mahogany risers were curfed to allow the wood to be bent. The steps themselves were also given an identical curve.

Compass Curved treads

There was a sharp bend in the staircase itself where it curved around near the upper level of stairs. To achieve this bend, we employed the use of a large homemade compass when cutting the steps.

Knotched steps Curved steps
Each step was precisely curved and knotched where they met both the inner and outer stringer (click to enlarge)

Special care also had to be taken to ensure that the knotches and curves on the other side of each step, on the outer stringer, were even and identical. Once completed, the balusters will fit around these cutouts.
