Local context
Why Homeowners in Renton Choose This Service
Remodels in Renton usually start with the stair that is already there. With postwar homes and hillside split-levels common here, we plan layouts and materials that suit the existing architecture rather than forcing a one-size design.
Renton combines postwar neighborhoods near downtown with hillside developments and newer townhomes.
We serve neighborhoods such as Highlands, Kennydale, Fairwood, Talbot Hill, about 12 miles from Seattle.
