What goes into a new foundation in Fremont?
Foundation installation in Fremont means building the base your house or addition rests on. That's either a slab poured right on the ground or a raised foundation with a crawlspace under it, picked to suit your soil, your lot and your budget.
Most people who call about a foundation are building a new house or adding onto one, and they haven't settled what it should sit on yet. The price moves with the size of the footprint, the type you pick, how much your clay moves and how much digging the slope calls for. The schedule turns on paperwork first, because the soils report and any permit come before we dig. The estimate puts our price and the work for your lot in writing.
When does a Fremont project need a new foundation?
Plans for a new house
You've got a lot and drawings, and the foundation is the first thing that goes in and the hardest thing to change. Picking the type after the plans are final can mean redrawing them, so it pays to have us look early.
An addition off the house
A new room needs its own base that sits level with the floor you already walk on. When the two are built differently, the seam between them is usually where cracks show up first.
Yard that cracks every summer
Long cracks in the dirt by late summer and sticky mud after rain usually mean clay. If the foundation isn't planned for it, the movement shows up later as cracked floors and doors that stick.
How we handle foundation installation
I want to see your soils report and the slope of the lot before we talk slab or raised, because the ground and your budget make that call, not us. Once the type is settled, our crew lays out the footprint and digs out and packs the subgrade, the ground the concrete sits on, so it doesn't settle under the house. Then we build the forms, set the rebar, the steel that holds the concrete together when the ground pushes and pulls, and pour. The base is the part nobody sees and the first thing people want to cut from the budget, and it's the last thing I'll cut, because a good-looking foundation on a bad base cracks and my name is on it.
A raised foundation stands on concrete footings, and we pour those as their own job for walls and additions too. If you're putting up a small commercial building, we also handle concrete parking lot building so the lot and the building get planned together.

What happens when you call about a foundation in Fremont?
Here's how a foundation job runs from your first call to a clean site, and what you'll have in hand before anyone digs.
Call and set a visit
You call or send the form, and I come out to walk the lot, measure it and ask what you need the foundation to do. That visit is where we talk through slab or raised for your ground.
Get the work in writing
You get a written estimate that spells out the base, steel and joints, so you can see what you're paying for and compare it with other bids. If the number runs high, we'll show you which choices move it.
Sort out the permit
We sort out any permit before we dig. In Fremont, every building permit ends with a city inspection that checks the work against the approved plans and closes out the permit.
Prep, pour and clean up
Our crew does the digging, base, forms, steel and pour with me on site. We clean up before we leave.
Why Fremont homeowners call Ironset Fremont Concrete for foundations
On a foundation, the soil decides more than the concrete does, so bring us your soils report and ask for an estimate.
The owner looks at your job
I come out to look at the job myself, and our crew does the prep, forms, pour and finishing. When you have a question about your foundation, you're talking to the person who wrote your estimate.
A licensed name on your permit
We're licensed and fully insured. A foundation goes through permits and inspections, so the contractor on that paperwork should be one you can check before you sign.
Learned by fixing bad slabs
I learned this trade fixing slabs other people got wrong, and made it a full business in 2021. Most of our calls come from Fremont homeowners and their neighbors who saw our work.
Foundation installation, soil and permits in Fremont
In Fremont, the city's Permit Center handles building permits for new homes, additions, alterations and repairs. Its list names that work and doesn't name foundation installation on its own, so whether your job needs its own permit is the Permit Center's call, and we ask before we dig. When a permit is needed, we handle the paperwork and inspections with them.
The ground is the bigger local story. California clay swells in winter rains and pushes up on a foundation, then shrinks in dry summers and pulls away, which is why the soils report carries so much weight. The state also maps liquefaction zones, where the soil under a foundation has to be investigated and countermeasures built into buildings meant for people, and cities and counties have to use those maps when they issue permits. In May 2026 the state released preliminary earthquake fault zones for public review that affect Fremont, and the building office has the final word on where your lot stands. We plan for the same seasonal clay on jobs in Union City and Newark, and we're based in Fremont and take jobs in the cities around it.
Questions about foundation installation in Fremont
How do I choose between a slab and a raised foundation in Fremont?
Start with the soils report, because the choice turns mostly on your budget, your design goals and the expansion index in that report, which rates how much the clay on your lot swells. One foundation guide written for another region finds that risk usually drops as foundation cost rises, with shallow systems carrying more risk than deep ones, and many owners accept some of that risk to keep the price down.
How much does a new foundation cost in Fremont?
A slab foundation in San Francisco usually costs about $7 to $18 per square foot installed, which gives you a frame for a Fremont slab before anyone has measured your lot. A raised foundation prices differently, so the written estimate after I see the lot is the number to plan on.
Who can legally build a foundation in California?
Only a contractor licensed by the state contractor board, because California law requires a license for anyone who bids on or contracts for a job worth $1,000 or more in labor and materials. Any project that needs a permit or workers also needs a licensed contractor, so ask for the license before you sign anything.
What causes a new foundation to crack?
Most cracks start under the concrete, with a base that was raked level instead of dug out and packed, or with clay the design didn't plan for. Pouring in midday heat leaves a weak top, and skipping control joints, the cuts that give concrete a planned place to crack, lets it crack wherever it wants. We pack the base, plan around your soils report and time the pour and the cuts so the concrete isn't fighting the heat.
Does an older Fremont home need a review before foundation work?
If the property is 50 years or older, Fremont requires a historic evaluation before it issues permits for demolition, relocation or exterior changes. If your house is that age, tell us at the estimate so we can plan the permit around it.
What should I have ready before a foundation estimate in Fremont?
Have the address, a rough idea of how the lot slopes and your soils report if you've got one. If you don't have a report yet, tell us when you call (510) 574-8512 or send the form, since it's the first thing I'll ask about.
Other concrete work that goes with a foundation
Concrete footings
Footings are the wide concrete strips that carry a raised floor, a wall or post, and their depth and steel decide how well everything above holds.
Concrete parking lot building
Building a small office, shop or rental with its own parking? We pour the lot with a packed base and a slope that carries water off the lot.

Get your foundation type settled early
The foundation type shapes your plans and your permit, so settling it before the drawings are done saves changing them later.
