Local context
Why Homeowners in Mercer Island Choose This Service
Railings set the tone of an entry. Many Mercer Island homes, including midcentury homes, still have original or builder-grade railings, so replacing infill, rails, and posts is often the most visible upgrade for the budget.
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.
