What does it take to put a new foundation under a house in Petaluma?
Foundation installation in Petaluma means building the concrete base a house sits on and is tied to, for a new home, an addition or an older house that needs a replacement. Done right, it carries the house's weight evenly and is built to hold the house in place when the ground shakes.
Most people who call us about a foundation are building a new house or an addition, or they live in an older home whose foundation is cracked, crumbling or missing under part of it. If the old foundation is sound and the house has only dropped, foundation raising may be the better fix, and I'll tell you so when I see it. The price turns on the layout, the size and depth your engineer calls for, how much digging and steel the plans need, and how easy the site is to reach, while the schedule turns mostly on the city's review and the weather for the pour. Your written estimate lists what's included, so you can see what goes into your own figure.
How do you know a house needs a new foundation?
Cracks in walls and floors
Cracks that run across drywall, plaster or the floor, especially ones that keep getting longer, usually mean the ground under the house is moving or the old foundation is breaking up. Waiting lets the damage spread into the framing, doors and plumbing, and that adds to the repair.
Sticking doors, sloping floors
When doors stop latching and a marble rolls across the floor, part of the house has usually dropped. The longer it sits that way, the more the frame twists and the more work it takes to bring it back level.
Crumbling or missing foundation
On older homes we find concrete that flakes when you scrape it, wood posts sitting on bare dirt, or stretches with no foundation at all. A house like that may not be tied down well enough for an earthquake, so it's worth having someone look at it before the next one.
How we handle foundation installation
I start by reading your approved plans and talking with your engineer about anything the site raises, and I keep in touch with them as the job goes along. Our crew lays out the foundation, digs the footings to the depth and width on the plans, and packs the bottom of the trench so the concrete sits on firm ground instead of loose dirt. We set the forms and tie in the rebar, the steel inside that holds the concrete together when the ground or the house pushes on it. On a crawlspace home I pay close attention to how the house will be anchored, the bolts and hardware the plans call for that the frame gets fastened to, because that's what keeps the house tied to its foundation in an earthquake. Then we pour, finish the top so the framing sits level, and keep the concrete damp while it cures, which is the slow gain in strength it needs before it carries weight. If the budget gets tight, the digging and ground prep are the last place I'd cut, since they're buried by the end of the pour and nothing built on top can make up for them.
Some jobs need more than the house foundation. A deck, a porch or a small addition often rests on concrete footings, separate pads poured under the posts or walls that carry it. For property owners and small businesses, we also take on concrete parking lot building, where the same care with the base decides how the lot holds up.

What happens after you call about a foundation
Here's how a foundation job runs from your side, from the first call to the final walk-through, with the city's review in the middle.
Call us or send the form
Reach us at (707) 283-3110 or through the form, and have your address, your home's layout and any plans handy. If you know your lot sits in a Flood Plain-Combining or Floodway zone, tell us then, because it adds a permit.
I visit and write it up
I come out, look at the site and ask how you'll use the house and the space under it. You get a written estimate that lists what's included, so you can read through it line by line.
We handle the city steps
We help with the permit application and plan our start around the city's approval and inspections. Some Petaluma permits come back at submission or within a few days, but most take a few weeks or even several months, so that wait usually sets the start date.
We build it and walk it
Our crew forms, pours and finishes the foundation, with the city's inspections fitted in where the permit calls for them. Before we pack up, I walk the finished job with you.
Why Petaluma homeowners call Allied Petaluma Concrete for a foundation
On a foundation, the work that matters most is buried by the end of the pour, so it's worth asking about before anything else. Send us your address and plans and I'll set up a time to come out.
The owner writes your estimate
I come out myself to look at the site and the plans, and I put the estimate in writing with what's included spelled out. You'll know what you're paying for before anything gets dug.
Our own crew pours it
The forming, pouring and finishing are done by our own crew. That keeps the details from the plans and from our talks with your engineer with the people who build it.
Licensed and fully insured crew
Allied Petaluma Concrete is licensed and fully insured. That protects you and your property while the ground is open and the forms are up.
Building in Petaluma since 2013
I learned concrete on a flatwork crew, came back to the trade in 2013 and started this business in Petaluma. I'd rather tell you plainly what concrete will and won't do than promise more than it can give.
Foundations, footings and permits in Petaluma
The city's Building Division lists foundations among the new work that needs a building permit, and its exemption for flatwork leaves out concrete that holds up a structure, so plan on a foundation going through the city's permit process. You fill out an application and pay a fee, and in most cases city staff review and approve the engineering plans. We help with the application and plan our start around the city's approval and inspections. Some lots have another step. In Petaluma's Flood Plain-Combining and Floodway zones, nothing gets built or altered without a development permit first. In the state's Liquefaction Zones, which cities use in permitting, the stability of the soil under the foundation has to be looked into and countermeasures built into homes, so if your lot sits in either kind of zone, plan for that from the start.
We're based in Petaluma and work in the cities around it across the North Bay, where we meet a lot of older crawlspace houses and additions going onto existing homes. On those jobs we look closely at where the new work ties into the old and how water runs off the lot, and we bring the same care to jobs in Novato and Santa Rosa.
Questions about foundation installation in Petaluma
Do I need a permit for a new foundation in Petaluma?
Yes, Petaluma lists foundations among the work that needs a building permit, so plan on one for any new or replacement foundation. All work in the city, permitted or not, also has to meet the California Building Standards Code and city ordinances. If you have a question about your own project, the Building Division answers them at building@cityofpetaluma.org.
How much does foundation installation cost in Petaluma?
Your price comes from your plans and your lot, and you get it as a written estimate after I've seen the site. The biggest drivers are the layout, the foundation's size and depth, how much steel and digging the engineer calls for, how easy the site is to reach, and any extra permit steps your lot needs.
What can an earthquake do to a crawlspace foundation?
In an earthquake, a cripple wall that isn't anchored well enough can let the house slide off its foundation, and one that isn't braced well enough can collapse. That's why anchorage and bracing are the first details worth asking any contractor about on a crawlspace home.
What causes a house foundation to crack and move?
A common cause is soil that shrinks and swells, lifting the house when it gets wet and letting it settle as it dries, often more than a house can take. Research on homes in general finds that this movement commonly cracks floors and walls, which is why the ground under the site matters when the foundation is planned.
How long does foundation installation take in Petaluma?
The city's permit review is usually the longest wait, and the work on site starts once it's approved, as the steps above lay out. How long our crew is on site depends on the layout and size, plus the time the concrete needs to cure before framing goes on, and I'll talk that through when I see the site.
Will my new foundation crack like the old one?
Most concrete gets a few fine hairline cracks as it shrinks and cures, and I'd rather say that plainly than promise otherwise. Cracks that open wide and keep growing usually come from moving ground or a weak base, which is why most of our care on a foundation goes into the work that ends up buried.

Concrete footings
When a deck, porch or small addition needs its own support, footings poured to the right depth carry that weight down into firmer ground.
Concrete parking lot building
Property owners and small businesses who need parking poured get a deep, packed base and planned drainage, so the lot holds up under daily traffic.
