A structure is only as solid as what it sits on. We pour concrete footings in Brentwood built to handle local clay soils, seasonal ground movement, and California seismic requirements - with permits handled from start to finish.
Concrete footings in Brentwood are the buried bases that hold up decks, fences, retaining walls, additions, and outbuildings - most residential footing projects take one to three days of active work, with a permit inspection required before the pour and a few days of curing before construction above can continue.
Most homeowners reach out because they are starting a new project - an ADU, a deck, a detached garage - and need the foundation work done right before framing begins. Others call because an existing structure has started to lean, sink, or pull away from the house, which usually points to a footing that has shifted or failed. In Brentwood, that shifting almost always traces back to the clay-heavy soils throughout eastern Contra Costa County: clay expands when it absorbs winter rain and shrinks back through summer, and that cycle moves anything sitting on top of it that was not built to handle the load properly. Our foundation raising service addresses cases where an existing structure needs to be leveled after footing movement.
For larger projects like new home additions or ADU builds, our foundation installation service covers the full perimeter and slab foundation work that those structures require.
Any new deck, fence post, pergola, detached garage, or backyard structure needs a footing to stay stable over time. If you are planning a project and a contractor has not mentioned footings yet, ask - it is one of the first things that should be discussed. Skipping this step is one of the most common reasons backyard structures fail within a few years.
If a deck, fence, or outbuilding has started to tilt, sink on one side, or separate from the wall it was attached to, the footing underneath may have shifted or failed. In Brentwood, this is especially common after a wet winter followed by a dry summer, because clay soils expand and contract with moisture changes. This kind of movement does not fix itself - it typically gets worse.
Cracks that run diagonally from corners or that are wider at the top than the bottom often point to uneven settling in the footing below. Brentwood expansive soils can cause this kind of differential movement, where one part of a footing moves more than another. A contractor can assess whether the cracking is cosmetic or a sign of a structural problem that needs attention.
If a home inspector noted concerns about settling, inadequate support, or unpermitted structures, that is a direct signal to have a concrete contractor evaluate the footings. In Brentwood competitive real estate market, addressing these issues before listing can make a meaningful difference in whether a deal closes without complications.
We handle footing projects from the permit application through the final city inspection and pour. That includes 811 utility locating before any excavation, digging to the depth required to reach stable soil, setting forms or reinforcement, coordinating the pre-pour city inspection, and the concrete pour itself. Rebar or welded wire reinforcement is included where the project requires it - which in Brentwood is most of the time, given the soil conditions and California seismic requirements. We also close out the permit once the work is done so you have a clean record on file. For structures that need a full perimeter foundation rather than individual footings, our foundation installation service covers that scope.
In cases where existing footings have moved and the structure above needs to be lifted and re-leveled, our foundation raising service addresses the lifting, shimming, and re-support work required before any new footing work can hold correctly. Many Brentwood properties that have seen years of clay soil movement need both services on the same project.
Right for homeowners building or replacing a wood or composite deck that requires concrete piers at each post location to stay level over time.
Suited for property owners adding an accessory dwelling unit or room addition where a full continuous or isolated footing system is required by the city permit.
Designed for fence posts, gate pillars, and retaining walls where a poured concrete base is needed to keep the structure from leaning or shifting in clay-heavy soil.
Best for detached garages, workshops, and storage structures that need permitted, engineered footings to satisfy the City of Brentwood building inspection requirements.
Two local conditions shape how footing work is done in Brentwood and the surrounding East Contra Costa area. The first is clay soil. Much of the region sits on ground with high clay content, which expands when it absorbs winter rain and shrinks as it dries through summer. That seasonal movement puts repeated stress on any footing that was not dimensioned specifically for it. A footing that might be adequate in sandy Bay Area soils can fail in Brentwood conditions within a few seasons. The second condition is seismic zone. All of California is seismically active, and footings here are required to account for ground movement from earthquakes - which means specific reinforcement connections between the footing and the structure it supports. Both conditions come up on every project we do in this area. We account for them in how we size and reinforce each footing before a single shovel goes in the ground.
We install footings throughout the region, including in Antioch and Pittsburg, where the same clay soils and seismic requirements apply. Brentwood growing ADU market means we have processed a significant number of ADU footing permits through the City of Brentwood Building Division, and we know the plan check and inspection process well. That familiarity reduces delays for your project.
We respond within 1 business day. Most footing quotes need an in-person visit - we need to see the site, understand what is being built, and check soil conditions before giving you an accurate number. The estimate visit is free and typically takes 30 to 60 minutes.
You receive a written estimate covering excavation, forming, materials, reinforcement, and permit fees - before you commit. We then file the permit application with the City of Brentwood Building Division, which typically processes in one to two weeks for straightforward residential projects.
Before excavation begins, we call 811 to have buried utility lines marked. Clear the work area of plants, furniture, or stored items before the crew arrives. Digging, forming, and setting reinforcement usually takes one to three days depending on project size.
A Brentwood building inspector visits to confirm the excavation and reinforcement match the approved plan - typically a 15 to 30 minute visit your contractor schedules. Once signed off, we pour the concrete. In summer, we use early-morning scheduling and curing additives to protect the fresh concrete from Brentwood heat.
Free estimate, permit handling included. We know the City of Brentwood process and the local soil conditions - you get both in one call.
(925) 504-0962We determine footing depth and dimensions based on the actual soil conditions on your site. In clay-heavy East Contra Costa soils, that usually means going deeper and wider than minimum code requires - because minimum code is written for average conditions, and Brentwood soils are more demanding than average.
Brentwood has processed a large number of ADU permits in recent years, and we have worked through that process many times. We handle the application, coordinate the plan check, and schedule the pre-pour inspection - so your ADU project does not stall at the permit stage. Verify contractor licensing through the{' '} <a href="https://www.cslb.ca.gov" target="_blank" rel="noopener noreferrer" className="text-secondary underline underline-offset-2">California Contractors State License Board</a>.
California building standards require footings to account for seismic forces - not just the load of the structure above. We include the reinforcement connections and embedment depth that satisfy those requirements on every permitted project, so your structure is built to current California standards from the ground up.
Pouring concrete footings in Brentwood summer heat without the right precautions creates weak spots that do not appear until a structure shifts years later. We schedule summer pours for early morning and use curing compounds on every hot-weather project - because properly cured footings are the only kind worth pouring. See concrete curing guidance at{' '} <a href="https://www.concrete.org" target="_blank" rel="noopener noreferrer" className="text-secondary underline underline-offset-2">concrete.org</a>.
Every footing we pour creates a documented, permitted record with the City of Brentwood - which protects your property value and prevents complications when you sell or expand the structure later. That paperwork is part of what you are paying for, and it is worth having.
