Slopes washing away, old walls leaning, or a backyard you just cannot use? We build concrete retaining walls in South Whittier that hold up to clay soils, heavy rain, and seismic conditions - starting with a free on-site estimate.
Concrete retaining walls in South Whittier hold back slopes and protect your yard, driveway, and foundation from soil erosion - most residential projects take two days to two weeks from excavation to finished wall, depending on height, length, and whether permits are required.
Most homeowners who call us have either watched a slope erode through a few rainy seasons, noticed an old wall starting to lean, or finally decided to deal with a backyard slope that has been unusable for years. South Whittier was largely built out in the 1950s through 1970s, so many original walls in the area are now 60 or more years old - often built before modern drainage and seismic standards were common.
If a retaining wall will create flat outdoor space for you, pairing it with our concrete floor installation work lets us finish the whole area in one coordinated project.
If soil washes down your hillside or collects at the base of a slope after a winter storm, the ground needs support. South Whittier rain tends to arrive in heavy bursts rather than steady drizzle, so even a modest slope can lose significant soil in a single storm. Left alone, erosion can undermine your yard, fence, or foundation over time.
A wall that has started to tilt forward, or shows horizontal cracks across its face, is under stress it was not designed to handle. This is common in older South Whittier homes where original walls were built without the drainage systems that are now standard. A leaning wall does not fix itself - it gets worse until it fails.
When a raised planting bed or slope borders a hard surface like a driveway or patio, the soil will eventually push into it or wash over it. You may notice the edge of your driveway cracking, pavers shifting, or soil collecting on the concrete after rain. A retaining wall creates a clean, permanent boundary that protects those surfaces.
If part of your yard is too steep to mow, plant, or let children play on, a retaining wall can turn that wasted space into a flat, usable area. Many South Whittier homeowners have used one or two walls to create a garden, a seating area, or simply a yard that is actually enjoyable. If you have been ignoring a slope, this is the service that changes that.
We build both poured concrete walls and concrete block walls, and the right choice depends on your wall height, the look you want, and the conditions in your specific yard. Poured concrete walls are formed on-site and work well for longer continuous runs or walls that need to handle significant soil pressure. Concrete block walls - sometimes called CMU walls - give you a clean, modular look and are well-suited for shorter walls and tiered landscaping projects. Either type gets the same gravel backfill and drainage system behind it, because drainage is what determines whether a wall lasts 50 years or fails in five.
We also handle terracing projects where two or more walls step up a steeper hillside, creating flat usable areas between each level. When those areas need steps connecting them, our concrete steps construction service integrates naturally with the wall work for a complete, finished result.
Best for longer walls, taller walls, or any situation where continuous strength and minimal visible joints matter.
A practical choice for shorter walls and tiered gardens where a modular, structured appearance fits the landscape.
Right for steep hillside lots where a single wall cannot address the full height change safely.
Designed specifically for slopes that are actively losing soil to rain runoff and need immediate stabilization.
For existing walls that are leaning, cracking, or lack proper drainage behind them and cannot be saved with repairs.
South Whittier sits on clay-heavy soils that are common throughout the Whittier-area foothills and the broader Los Angeles Basin. Clay soil absorbs water and swells - sometimes significantly - and that swelling pushes against the back of a retaining wall with real force. Combine that with Southern California winters that can drop most of the year's rain in just a few heavy storms, and you have conditions that test every wall every season. A wall built without proper drainage behind it will not handle those winters for long. Homeowners in Hacienda Heights and Whittier face the same soil and drainage challenges, and we work throughout both areas regularly.
South Whittier is also an unincorporated community, which means permits for retaining walls go through the LA County Department of Public Works - not a city building department. The county also requires that walls above a certain height be designed to handle lateral seismic forces, because the Whittier Narrows fault zone is nearby and remains active. This is not just red tape. A wall that is only designed for the weight of soil - and not for ground movement - is a genuine risk in this neighborhood. We handle the permit process and coordinate engineer reviews when required, so you are not navigating that on your own.
Call or message us and we will schedule an in-person visit. A retaining wall quote based only on a phone description is not reliable - we need to see your slope, measure the area, and check soil conditions. You will receive a written estimate within a few days of the visit.
If your wall will be four feet tall or higher, we apply for the required LA County Department of Public Works permit before any work begins. Permit approval in unincorporated LA County typically takes one to four weeks - we keep you updated so there are no surprises on timing.
The crew excavates the footing trench, clears vegetation, and sets up drainage materials behind where the wall will go. This is the noisiest phase of the project. Move patio furniture, potted plants, and vehicles out of the work zone before the crew arrives.
For a poured wall, we build forms and pour concrete. For a block wall, we lay courses on the prepared footing. Once cured, we backfill with gravel and soil, grade the surface, and do a final walkthrough with you to confirm the wall is plumb and the drainage is working.
Free on-site estimate. We handle LA County permits. No pressure, no obligation.
(562) 586-9375We hold a current California contractor license - verifiable on the CSLB website in minutes. Every retaining wall project is covered by liability insurance so you are protected from start to finish.
The clay-heavy soil in South Whittier swells when wet and shrinks when dry. We install gravel backfill and drainage pipes behind every wall, specifically because skipping that step is the single most common reason walls in this area fail within a few years.
South Whittier is unincorporated, so permits go through LA County - not a city building department. We have pulled permits through this office many times and manage the entire application and inspection process on your behalf.
South Whittier sits close to an active fault zone. For walls that require it, we coordinate with licensed engineers to ensure the design accounts for lateral seismic forces - not just the weight of soil - which the county requires and which protects your property.
Every retaining wall we build in South Whittier is designed for local conditions from the ground up - proper drainage, the right footing depth, and full permit compliance. That combination is what makes the difference between a wall that holds for decades and one that needs attention after a few rainy seasons.

Retaining wall design standards are published by the American Concrete Institute. Seismic hazard information for South Whittier is available from the California Geological Survey.
