Sliding soil and crumbling slopes cause real damage. We build concrete retaining walls in Brentwood that hold back the hillside, handle permits, and create flat, usable space where there was none.
Concrete retaining walls in Brentwood are built to hold back sloped soil, prevent erosion, and create usable flat space on hillside lots - most standard residential walls take two to five days of active work, with permit timelines added for taller walls that require city review.
Most homeowners reach out because a slope is creeping, an old wall is leaning, or they want to reclaim space on a property that is too steep to use. In Brentwood, the clay-heavy soil and wet-dry climate cycle make retaining walls more critical here than in a milder, sandier environment. Water builds up fast behind a slope in a wet winter, and clay soil that has absorbed that water loses its grip quickly. If your project also needs hardscaping near the base of the wall, take a look at our concrete floor installation service. For properties with sloped steps that need rebuilding, our concrete steps construction work is closely related.
If you can see a slope that is slowly moving - soil piling up at the base, cracks forming in the ground above, or a fence post that has started to lean - the hillside is no longer stable on its own. In Brentwood, this often becomes obvious after a wet winter when the clay soil has absorbed a lot of water and lost its grip. Do not wait for the movement to reach your foundation or driveway before acting.
If an existing wall is tilting forward or you see cracks running horizontally across it, the wall is under stress it can no longer handle. Horizontal cracks in particular are a warning sign that pressure behind the wall is winning. A leaning wall does not fix itself - the longer it is left, the more soil movement and damage accumulates on both sides.
When rain runs down a slope and carves small channels in the soil, or water collects at the bottom of a hill and sits there, the slope is actively eroding. Brentwood winter rain events can move a surprising amount of soil in a single storm. A retaining wall with proper drainage redirects that water before it causes damage to your yard or structure.
If part of your yard is too steep for a lawn, a patio, or a garden, a retaining wall can create a level terrace where there was none. This is common in Brentwood neighborhoods built on hillside lots where usable backyard space is limited. If you have been looking at a slope and wishing it were flat, that is a good reason to call for an assessment.
We build concrete retaining walls for residential properties throughout Brentwood and the wider East Bay. Every project starts with a site visit to assess the slope, soil conditions, and what the wall needs to hold back. We excavate to stable soil for the footing, build and pour the concrete wall, and install drainage - gravel backfill and perforated pipe - behind the wall as it goes up. That drainage step is the part homeowners never see, but it is the part that determines whether the wall lasts 10 years or 50. We pull all permits before work starts and coordinate city inspections so the job is fully documented and code-compliant. For properties that also need flat concrete surfaces at the base of the wall, our concrete floor installation service handles patios, slabs, and flatwork in the same project sequence.
Retaining walls on stepped or terraced lots often connect to staircase work. Our concrete steps construction service builds or replaces the steps that connect terraced levels - a natural companion project when a wall creates new elevation changes on a property.
Best for taller walls or those carrying significant loads - monolithic concrete is the most durable option for hillside and engineered applications.
Suited for shorter walls and garden terracing where a finished block appearance fits the landscape design.
Ideal for steep lots where a series of shorter walls creates multiple usable levels rather than one tall, heavily loaded wall.
Right for any wall project where soil saturation has caused past failures - drainage installation is always included as a standard part of our builds.
Two local conditions shape every retaining wall project in Brentwood. First, the clay-heavy soils throughout East Contra Costa County swell when wet and shrink when dry - a cycle that repeats every year and puts constant pressure on whatever is holding the slope back. A wall built here needs a deeper footing than it might in sandier soil, and the drainage system behind it needs to handle Brentwood wet-season rain events without letting water build up. Second, Brentwood expanded rapidly in the 2000s, and some of that growth left behind graded lots with fill soil that has not fully settled. Fill is less stable than native soil and can shift more dramatically on sloped properties - something worth assessing before deciding how the wall needs to be built.
We serve properties throughout the region, including in Antioch and Oakley, where the same clay soils and permit requirements apply. Whether your home is in a newer Brentwood subdivision with an active HOA or on an older property closer to Marsh Creek Road, we know what local soil and city process require.
We respond within 1 business day. Retaining wall quotes cannot be done over the phone - we need to see the slope, measure, and assess soil conditions. We schedule a free on-site visit and come to you.
After the site visit you receive a written estimate covering materials, labor, drainage, and any permit fees. If your wall requires a city permit - which taller walls do - we explain the timeline and handle the application so you do not have to.
We excavate to stable soil, set footings, form and pour the wall, and install drainage material behind it as the wall goes up. Most standard residential walls take two to three days of active construction once permits are in hand.
Once the wall passes city inspection, we backfill and clean up the site. Concrete needs about a week before the area behind the wall should be loaded. We walk through the finished work with you and explain what to watch for in the first wet season.
We respond within 1 business day. After you submit, someone from our office will call to schedule a free on-site estimate at a time that works for you. No obligation, no sales pressure.
(925) 504-0962We apply for all required City of Brentwood permits as part of every project - not as an add-on, not after the fact. For walls over the height threshold, we manage the engineering review and inspection scheduling so the job is fully code-compliant before we ever break ground.
Every wall we build includes properly installed gravel backfill and perforated drain pipe behind the wall, with weep holes at the base. In Brentwood, where wet winters follow dry summers, drainage is not optional - it is what separates a wall that lasts decades from one that fails in five years.
We work throughout East Contra Costa County and have built walls in Brentwood, Antioch, Oakley, Pittsburg, and beyond. The clay soil conditions, fill-lot issues, and permit process here are not surprises to us - they are the standard conditions we plan for on every job. That local experience is why our customers in newer subdivisions do not face unexpected problems mid-project.
Many Brentwood neighborhoods require HOA approval before structural work begins. We have worked in subdivisions with strict design standards and can help you understand what your association requires - and how to design the wall to meet both city code and HOA rules - before you commit to the project.
Retaining walls are one of the most consequential concrete projects a homeowner can undertake - a wall that fails can damage everything below it. We build them to pass inspection and to hold up through Brentwood winters, not just to look right from the street. See what the American Concrete Institute recommends for quality concrete construction.
