What’s different about concrete in Renton
Slopes and hills
Talbot Hill, Kennydale and the edges of the Highlands have sloped lots, steep driveways and yards that need walls or steps.
Soil and water
The Cedar River valley and the area near the lake have softer, wetter soils than the hills. Settled patios and sunken walk panels are common there. Low spots that hold water through winter are a common reason slabs fail. Base depth and drainage get extra attention on valley lots.
Sidewalks and right-of-way
Renton issues Right-of-Way permits through its online permit portal, and work on sidewalks, curbs or driveway aprons along the street needs one.
Trees
Street trees and big firs along lot lines lift walks and driveway edges, especially in older parts of the Highlands.
Lots and access
Many lots have good access from the street. Hillside back yards and fenced side yards can still need a pump or a long wheelbarrow run.
Homes we see
Post-war houses in the Highlands, mid-century homes in Kennydale and Talbot Hill, and newer subdivisions on Benson Hill and in Fairwood.

Concrete in Renton: common questions
Do I need a permit for concrete work in Renton?
Patios and walks on your own property are often exempt, but retaining walls over 4 ft from the bottom of the footing and work in the right-of-way need permits. Renton Permit Services handles both, and many permits can be applied for online.
Can a sunken Renton patio be lifted instead of replaced?
Often, if the slab is in one piece. Lifting works best when the soil underneath has stopped moving. If the base is wet and soft, replacement with a new base is usually the better fix.
Do you work in both the valley and the Highlands?
Yes. The ground is different, so the base and drainage plan is different, but the services are the same across Renton.
