“Washington Retaining Wall completely transformed our backyard with a beautiful stone retaining wall. The crew of three worked efficiently and finished the 20-foot section in just four days. They left the site spotless and the drainage system they installed is already handling our spring runoff perfectly.”
Natural Stone Retaining Wall
“Had a serious erosion problem on our sloped yard and these guys came through. They built a solid block retaining wall that stopped the soil loss immediately. The whole project took about a week and a half, and honestly the quality blew my expectations away.”
Residential Retaining Wall Installation
“We were losing our backyard to erosion every time it rained hard. Washington Retaining Wall designed and installed a stone retaining wall with proper drainage that fixed the problem completely. Best part? They explained everything clearly and didn't try to upsell us on stuff we didn't need.”
Slope Stabilization & Erosion Control
“Our old timber retaining wall was leaning badly and we thought we'd need a total replacement, but they were able to repair and stabilize it instead. Saved us a ton of money and it looks great. The crew was professional and respectful of our property throughout.”
Leaning Wall Repair
“Absolutely stunning natural stone retaining wall now frames our garden. The team carefully placed each boulder and the finished look is exactly what we wanted. Took them three weeks to complete the 30-foot wall, and the cleanup at the end was thorough.”
Boulder & Natural Stone Wall
“Our old railroad tie wall was falling apart, so we had Washington Retaining Wall replace it with a modern block retaining wall. The whole crew moved fast and removed all the old material without making a mess. Really impressed with the attention to detail on the new drainage system.”

When Washington homeowners search for a retaining wall contractor near me, Washington Retaining Wall is the local crew they find and trust. We design, install, repair, and replace retaining walls on sloped and hillside lots across Washington and the surrounding area.
Our region brings real challenges: expansive clay soil that swells with winter rain, steep cut-and-fill lots, and saturated backfill that is the number one cause of wall failure. Every wall we build is engineered around drainage first. Request a free estimate and we'll assess your slope with no obligation.
Retaining wall repair is where we see the most urgent calls. A leaning or bowing wall is almost always a drainage problem: water trapped in saturated backfill builds hydrostatic pressure, and expansive clay soil pushes the wall outward, especially after heavy winter rain.
Cracking, bulging, sinking, and settling follow from clogged or missing weep holes and French drains, an undersized footing, or poor compaction. Small movement rarely stops on its own, and a minor lean can become a collapse once soil is fully saturated. Call us at (771) 252-1406 and we'll take a look.
We diagnose the real cause, correct the drainage, and rebuild only what's needed. Contact us to discuss your wall.
Washington Retaining Wall builds with the full range of materials and matches each to your site: segmental block and SRW systems (Allan Block, Versa-Lok, Keystone), poured concrete and reinforced CMU for tall or surcharge-bearing walls, boulder and natural stone that drains through the gaps, and pressure-treated timber for low garden beds. Taller walls get geogrid reinforcement, and every wall is built with gravel backfill and working drainage.

Retaining walls in Washington are typically quoted per square foot of wall face, and typical ranges depend on the material, wall height, drainage and excavation, site access, and whether engineering is required. A low block garden wall on level ground sits at the bottom of the range; a tall engineered hillside wall with tiebacks sits well above it. Final pricing depends on site conditions, so visit our pricing page or request a free on-site estimate.
In most jurisdictions, a retaining wall permit is tied to height and load. Commonly, walls over about four feet measured from the footing require a permit, and a wall supporting a surcharge such as a driveway or structure often needs one at a lower height, along with engineered drawings. Thresholds, fees, and setback rules vary by city, so none of this should be treated as a fixed rule. Washington Retaining Wall can advise on what the process typically looks like for your project. Requirements vary, so always verify with the Washington building or planning department before starting your project. Get in touch and we'll walk you through it.
