About working in Wilsonville
What we've learned installing retaining walls in Wilsonville.
Wilsonville sits at the I-5/Hwy 99W intersection, which makes it logistically efficient for us. The mix of newer subdivisions, established neighborhoods, and townhouse communities means we see a wider range of project sizes here than in any other city in the corridor.
Terrain & soil
Flat-to-gently-rolling lots dominate. Soil profile is consistent — loamy topsoil over clay 12-18 inches down, which makes drainage planning predictable. The flat terrain means most patios and walkways can be laid without the engineering complications we see in West Linn or Oregon City.
Properties we work on
Mix of subdivisions from the 1990s onward, plus newer master-planned communities (Villebois, Frog Pond). Lot sizes range from townhome-sized (0.08 acre) to 0.4 acre on the older neighborhoods. HOA architectural review is common — we know the process.

Common questions
What Wilsonville homeowners ask about retaining walls.
How much does a retaining wall cost?
Retaining walls in our area typically run $10,000–$30,000. The drivers are wall height, soil conditions, drainage requirements, and material (block, stone, or timber).
How tall can you build a retaining wall?
Standard residential walls run 2–4 feet. For walls above 4 feet we engineer with stepped or tiered designs, geogrid reinforcement, and drainage systems built in. Tall walls require permits — we handle that.
Why do retaining walls fail, and how do you prevent it?
Walls fail because drainage was an afterthought. We design drainage first — perforated pipe behind the wall, crushed gravel backfill, weep holes where needed — then build the wall around that system.
Do retaining walls come with a warranty?
Yes, 5-year warranty on every retaining wall install. Warranty terms attach to your signed contract.
Do you require an upfront payment?
No. We never require upfront payment. The free site visit gives you a locked quote, and you're not invoiced until the work is complete.
