Introduction
Staircase Replacement for Mercer Island Homes
Full staircase replacement when the existing stair is failing, unsafe, or poorly laid out. WA Stair Guy provides staircase replacement for homeowners in Mercer Island, King County, and nearby communities in the Eastside area.
About the Service
When stringers are damaged, the stair is out of code, or the layout does not work, replacing the entire staircase is often the better investment. We remove the old stair and build a new one sized for the opening. More about staircase replacement
Local context
Why Homeowners in Mercer Island Choose This Service
Remodels in Mercer Island usually start with the stair that is already there. With midcentury homes and large custom remodels common here, we plan layouts and materials that suit the existing architecture rather than forcing a one-size design.
Mercer Island is mostly single-family homes, many midcentury, along with larger remodels and new builds.
We serve neighborhoods such as First Hill, East Seattle, Mercerwood, about 6 miles from Seattle.

We plan the sequence to keep downtime as short as possible and discuss temporary access up front.
