Retaining Walls by Lee’s General Landscaping

Stop the erosion. Keep your hillside. Use your yard again.

Hey, it’s Mr. Lee. You’ve got a slope eating up your space? Or maybe the lawn’s sliding a little more every rainy season? That’s where a retaining wall can save the day—and your property.

We build tough, clean, good-looking retaining walls that do more than hold dirt. They give you back usable yard space, protect your home from erosion, and look great doing it. Whether you’re dealing with a steep hill or just want to level out an area for a patio, we’ve got you covered.


Why Build a Retaining Wall?

Here’s why Seattle homeowners call us for retaining walls:

  • Control Erosion: Stop soil from sliding and water from carving out your hillside.
  • Level the Land: Create flat, usable space for patios, gardens, and lawns.
  • Fix Drainage Problems: Walls help redirect water where you want it to go.
  • Boost Curb Appeal: A well-built wall adds structure and polish to any yard.
  • Protect Your Foundation: Water and soil can creep toward your home—walls stop that.

Our Retaining Walls Are Built to Last

  • We Start with a Solid Base: Every wall starts with deep excavation and compacted gravel. No shortcuts.
  • We Engineer for Strength: Proper block placement, geogrid support, and drainage—every time.
  • We Manage Water Properly: Poor drainage is the #1 reason walls fail. Ours include proper backfill and perforated drainpipes, so the wall can breathe.
  • We Build Clean & Tidy: When we’re done, the job site looks better than when we arrived. Guaranteed.

Types of Retaining Walls We Build

Block Retaining Walls

Our go-to for most yards. Durable, cost-effective, and flexible in height and design. Tons of block colors and textures to match your style.

Natural Stone Walls

For a more rustic, organic look. We use locally sourced stone and dry-stack with care for stability and style.

Repurposed Concrete Walls

We love recycling! If we’re demoing old concrete, we can often reuse it as building material. Great for rustic or modern designs.

Pressure-Treated Timber Walls

A more budget-friendly option with a natural feel. Works well for garden terraces, low walls, or rural properties.


When You Might Need a Retaining Wall

  • Sloped yard is eroding or unusable
  • You want to install a patio or garden on a hill
  • Water pools in one area after rain
  • Foundation is exposed or cracking
  • You’re losing soil down the hill every winter
  • You want more flat lawn for kids, pets, or entertaining

Permit Considerations

If your retaining wall is over 4 feet tall, most cities (including Seattle) require a permit. Don’t worry—we’ll walk you through it or help design terraced walls that avoid the permit process altogether. Either way, we play by the rules.
