Building a deck, addition, or retaining wall in Gilroy? We pour concrete footings that reach stable soil, meet seismic requirements, and clear the city inspection before construction starts.

Concrete footings in Gilroy are the buried base that holds up everything above them - a deck, a room addition, a retaining wall, or a covered patio - and most residential footing projects run one to three days from excavation to the pour, with the concrete ready for construction within a week of curing.
If you are planning any structure that attaches to your home or carries significant weight, footings are not optional. In Gilroy, the City of Gilroy Building Division requires a permit and an inspection of the footing before the concrete is poured - meaning a city inspector must confirm the depth and size are correct before the work gets buried underground. That inspection step is actually good news for you. It means a neutral expert has verified the job is right, which protects your investment for decades. Many homeowners in Gilroy combine footing work with a larger project, such as foundation installation, to get the structural base of their addition or new structure completed under a single coordinated scope of work.
We handle the permit, schedule the inspection, and give you a straight assessment of your soil conditions before we recommend a footing size - so you are not paying for more than your project needs, and you are not getting less than it requires.
Cracks that start near ground level and run diagonally or horizontally along a wall usually point to a footing that is shifting or settling below. In Gilroy, where clay soils expand and contract with every rainy season, this kind of movement is more common than in areas with stable sandy soil. A crack that has grown wider over the past year is a stronger signal than one that has stayed the same for a long time.
Walk across your deck or porch and pay attention to whether it feels level and solid. If one side sits noticeably lower than the other, or if the structure flexes more than it used to, the footings underneath may have shifted. This is especially worth checking after a wet Gilroy winter, when the soil has gone through a full swell-and-shrink cycle.
Any new structure that attaches to your home or carries significant weight - a room addition, a covered patio, a retaining wall - will need proper footings before construction begins. In Gilroy, the city permit process requires footings to be inspected before the concrete is poured. Starting without them puts your project and your property value at risk.
A fence post that is tilting or a retaining wall that is bowing outward often means the footing at the base has failed or was never deep enough. In Gilroy's clay-heavy soil, footings that do not reach stable ground are especially vulnerable to this kind of movement over time. If the lean is getting worse each season, the right call is to have it assessed before the problem gets more expensive to fix.
We pour concrete footings for a wide range of projects - decks, room additions, covered patios, retaining walls, fences, outbuildings, and ADUs. Every footing project starts with an assessment of your soil conditions, because the clay soils in this part of Santa Clara Valley require a different approach than the sandy or loam soils you find in other regions. We dig to undisturbed, stable soil rather than stopping at a standard depth, embed the required seismic reinforcement steel, and schedule the city inspection before any concrete goes in the ground. If your project is a larger structural build, we can coordinate the footing work with a full foundation raising scope so the entire substructure is handled under a single plan.
For homeowners in Gilroy's older neighborhoods - particularly the pre-1980s homes downtown and in the historic core - we also handle footing replacement and reinforcement on structures where the original footings no longer meet current standards. These projects require honest assessment of what is there before any work begins, and we give you a clear picture of what we find and what it will cost before we do anything extra.
Suits homeowners adding a new deck, pergola, or covered patio that needs proper structural footings to pass the city permit inspection.
Suits homeowners expanding their living space and needing code-compliant, seismically reinforced footings before the framing crew can start.
Suits homeowners building a new retaining wall or replacing one that has failed, where a proper footing base is critical to wall stability on Gilroy's clay soils.
Suits homeowners adding a detached ADU, garage, or workshop where a full footing system is required before any vertical construction can begin.
Two local conditions drive nearly every decision we make when pouring footings in Gilroy. First, the clay soils throughout the Santa Clara Valley swell and shrink with the seasonal rain cycle. A footing that sits in clay without reaching stable soil below it will move year after year - and the structure on top of it will follow. We dig past the clay to undisturbed ground, which is often deeper than a contractor using a standard spec would go. Second, Gilroy sits close to the Calaveras and Sargent fault systems, and California's building code requires structural footings in this area to be designed and reinforced for seismic movement. That means more steel, more coverage, and more careful inspection - but it also means your deck or addition is not going to shake apart if the ground moves. We serve homeowners throughout Gilroy and bring the same soil-and-seismic discipline to footing work in Morgan Hill and Hollister, where similar fault proximity and clay conditions apply.
Gilroy also has a meaningful stock of older homes - many in the downtown area and the historic core were built before the 1980s, when footing standards were less rigorous. If you are adding onto one of these homes, there is a real chance the existing footings nearby are shallower than today's requirements. We assess what is there before recommending anything, so you have a clear picture of scope and cost before any work begins. The City of Gilroy Building Division requires a permit and pre-pour inspection for most structural footing work, and we handle that process from application to sign-off. For more on California's seismic requirements, the California Seismic Safety Commission and California Geological Survey both publish resources that are worth reading if you want to understand the regional hazard picture.
We come to your property and look at the location, the soil, and what you are building. Most site visits take 30 to 60 minutes, and a written estimate follows within one business day. This visit is your chance to ask questions and get a feel for whether you are comfortable with the person you are hiring.
We apply for the permit through the City of Gilroy Building Division and arrange for underground utility lines to be marked before any digging begins - a free service in California that takes a day or two. We keep you updated so you always know where the permit review stands.
The crew digs to stable soil, sets the required steel reinforcement inside the forms, and prepares the site for the city inspection. Most residential excavations finish in a single day. The work area is off-limits until the pour is complete and the concrete has set.
The city inspector verifies the footing before any concrete is poured - this is a required step and a protection for you. After the inspection passes, the concrete truck arrives and the pour is typically done in a few hours. The footing needs about seven days to reach working strength, and your contractor will tell you exactly when the next construction phase can begin.
We assess your site, review your soil conditions, and give you a written estimate with no obligation. Most responses within one business day.
(669) 345-1108Gilroy's clay layer depth varies across neighborhoods - we dig until we hit stable, undisturbed soil rather than stopping at a fixed number. A footing that sits entirely in clay will move. One that reaches firm ground will not. That difference is what your structure's long-term stability depends on.
Gilroy sits near active fault systems, and we include the seismic steel reinforcement that California requires in this region on every footing we pour. The city inspector will verify it before the pour. You should not have to ask for this - it should be standard, and with us it is. See the American Concrete Institute for published reinforcement standards.
We apply for the City of Gilroy building permit, schedule the pre-pour inspection, and communicate with the Building Division on your behalf. Homeowners in Gilroy report that the permit step alone saves them hours of back-and-forth with the city - we handle it so you can focus on the rest of your project.
Many homes in Gilroy's pre-1980s neighborhoods have footings that are shallower than today's standards. We tell you honestly what we find when we dig, explain what it means for your project, and give you a clear cost picture before doing any additional work. No hidden charges, no pressure.
Every footing project we complete in Gilroy is permitted, city-inspected, and built to the seismic and soil standards that this part of California requires. That is not a talking point - it is the minimum your home deserves.
If your Gilroy home needs the foundation lifted or reinforced rather than just new footings, we handle the full raising scope with permits and inspection.
