Concrete work in Redmond
Redmond mixes flat valley neighborhoods along the Sammamish River with hillside subdivisions on Education Hill and around Grass Lawn and Overlake. Much of the housing is from the 1970s on, so we see plenty of first-replacement driveways, patios that have settled, and new slabs for garages and backyard structures.
We work across Education Hill, Grass Lawn, Overlake, Idylwood, Bear Creek, Willows/Rose Hill, Redmond Ridge and downtown.

What’s different about concrete in Redmond
Slopes and hills
Education Hill and the hills around Overlake and Bear Creek have sloped lots and stepped back yards, which brings retaining walls and steps into many projects.
Soil and water
The Sammamish valley floor has softer river soils and a higher water table than the surrounding hills. Valley-floor slabs need extra attention to base depth and drainage. Downspouts and yard drains that empty onto the driveway or patio are a common reason slabs settle and grow moss. We plan where water goes before we pour.
Sidewalks and right-of-way
Redmond requires a Right-of-Way Use Permit for work that modifies infrastructure in the right-of-way, including sidewalks, so driveway aprons and walks along the street need that permit.
Trees
Subdivision street trees and big Douglas firs at lot edges are behind a lot of lifted walks and cracked driveway panels.
Lots and access
Subdivision lots usually give decent access for trucks, which helps on driveways and patios. Back yards behind fences may still need a wheelbarrow route or pump.
Homes we see
1970s through 2000s subdivisions, townhomes, and new construction around downtown and Overlake.

Concrete in Redmond: common questions
Do I need a permit for concrete work in Redmond?
Ground-level patios and walks are often exempt, but retaining walls over 4 ft from the bottom of the footing and anything in the right-of-way, such as sidewalks and driveway aprons, need permits. Redmond’s Development Services Center can confirm for your lot.
Why do Redmond valley slabs settle more?
Lower areas near the Sammamish River tend to have softer soils and more groundwater than the hills. A deeper compacted base and good drainage reduce settling.
Can you match a new patio to an existing driveway?
We can get close with the same finish and joint layout. New concrete rarely matches weathered concrete exactly in color, so we talk about borders or a contrasting finish.
