Can my house be raised, and is it worth it?
Foundation raising lifts your house so its foundation can be replaced or the house can sit higher on piers, and Walnut Creek Concrete Works does this work in Walnut Creek and the cities around it in the East Bay.
This page covers both jobs people mean by it, lifting the whole house and adding support under a foundation that's settling, because the methods and the price are different for each. The price moves with the size of the house, whether we're only lifting it or also replacing the foundation or setting it on piers, and what shape the house is in. The schedule turns on permits, inspections, the weather and any engineer the job needs. Your estimate is written out so you can see each part of the job, and that's where your own figure comes from.
How do you know your foundation needs attention?
Floors that slope or dip
If a ball rolls across the kitchen or a hallway dips in the middle, part of the house has usually settled lower than the rest. Waiting lets the low side keep dropping, and the further it goes, the bigger the job to bring it back.
Doors that stick or won't latch
When doors that used to close fine start rubbing or won't catch, the frame around them has usually been pulled out of square by movement underneath. Planing the door fixes it for a season, but the foundation keeps moving.
Cracks that keep growing
Hairline cracks in concrete are common, but foundation or wall cracks that widen, run in steps or come back after patching usually mean the ground under the house is moving. The longer that goes on, the more of the house it pulls along with it.
How we handle foundation raising
I start by looking your house over to see whether it can handle a lift, because some houses aren't worth the stress, and then I lay out your options plainly. We help you plan where to stay during the lift, and I tell you up front that some drywall cracking can come with it, so nobody's surprised. Once the permit and any engineer's plans are in place, my crew and I lift the house, the new or repaired foundation goes in underneath, and we set the house back down and clean up. On the foundation itself, I care most about the subgrade, the ground it sits on, because that's hidden on day one and it decides how well the house holds up for years after.
A lift often brings other concrete work with it. If old slabs or walls need openings cut or sections taken out to make room for the new foundation, our concrete cutting work handles that, and if equipment or the new height leaves the driveway cracked or out of line with the garage, we can rebuild it through our concrete driveway building service.
Raising to replace the foundation
This suits a house whose foundation is past repair, because lifting the structure lets a new foundation go in underneath it. It costs more than a lift alone, but you end up with the house on a foundation built from the ground up.
Raising onto piers above the flood zone
This suits a house in a flood zone, because the house is lifted and set on piers or pilings so the living space sits above the flood level. It adds to the cost of the lift, and the city's flood rules shape how it's done.
Underpinning a settling foundation
This suits a house where most of the foundation is sound but one part is sinking or cracking, because underpinning adds support under the foundation you already have. It can steady the house without lifting the whole thing.

What happens when you call about raising your house in Walnut Creek?
Here's how a lift goes from your first call to the final walk-through, and who does what at each step along the way.
Call or send a message
Call (925) 532-0140 or use the form, and I'm the one who answers. We set a time for me to come see the house.
I walk the house with you
I look at the foundation, the framing and the site, and ask how you use the house. You get a written estimate that breaks out each part of the job, so you can see what drives the cost.
We line up permits first
If the job needs a permit, an engineer or a designer, we get that in place before we put anything on the calendar. The city requires an after-hours permit for construction on Saturdays and city holidays, so a weekend lift day gets that permit added.
Lift, set down, walk through
My crew does the work with me on site from the first jack to the cleanup. When it's done, we walk the house with you and go over what was done underneath.
Why homeowners here call us to raise a house
I look at every house myself
I come out to every job and check whether the house can take a lift before we talk about methods. If it isn't worth doing, I'll tell you that instead of selling you a job that won't hold up.
Learned on East Bay crews
I learned this trade on crews around the East Bay before starting this business in Walnut Creek in 2023. Three years in, I still answer my own phone, so you're never passed around.
Licensed and insured for your lift
We're fully licensed and insured. Your satisfaction, guaranteed, and if something about your house worries me, you'll hear it before the lift, not after.
On a lift, what the house sits on afterward matters more than anything you'll see, so tell us about your house and I'll come take a look.
Foundation raising, permits and map checks in Walnut Creek
Lifting a house physically changes your property, and the City of Walnut Creek requires a building permit when you do that, so plan on one. I tell you at the estimate, and we handle the application with the city. Two checks on your address come before the job starts. If the house sits in a Special Flood Hazard Area on FEMA's flood maps, the city applies its flood damage prevention rules to new development and additions, so email the Engineer on Duty at dutyengineer@walnut-creek.org to go over what applies to raising your house. Parts of Walnut Creek also fall on the state's earthquake hazard zone maps, and you can enter your address in the state's EQZapp tool to see whether yours does.
A lot of the houses we look at here are older, with foundations that have had decades to move, and that's usually where the conversation about a lift starts. We see the same kinds of houses on jobs in Lafayette and Orinda, and there the permit goes through whichever city or county office covers the address.
Questions about raising a house in Walnut Creek
How much does it cost to raise a house in Walnut Creek?
Raising a house usually costs about $10,000 to $60,000 per job across the US, and that covers just lifting the structure. A bigger house costs more, and so does lifting to replace the foundation or set the house on piers above the flood zone. Your written estimate breaks out each part for your house.
How long does it take to raise a house?
One national cost guide puts the whole process at 4 to 8 weeks on average, with the lift itself taking 2 to 7 days once preparation is done. Permits, weather and inspections all move that timeline, so plan the project around them instead of a fixed date.
Can we stay in the house while it's being raised?
No, being in the house during the lift isn't recommended, so plan another place to stay for the lift days. Before the lift, all the utilities get disconnected, including plumbing, electric, gas, heating, cooling, phone and internet. Your furniture and belongings can stay inside, but the crawlspace or basement needs to be emptied.
Will raising my house crack the walls?
Some cracking is likely, because one cost guide says a lift will probably bring some disruption to walls, floors and ceilings, like cracked drywall. Repairing it is separate from the lift, since California's licence class for raising and underpinning structures leaves out repairs to the parts of the house that stay in place. Ask how that repair will be handled before the work starts, and we'll go over it at the estimate.
What is the best way to fix a settling foundation?
Raising the house and underpinning the foundation are the two usual ways, and which one fits depends on the house's condition and what's wrong underneath. One pile maker's manual says helical piles, steel shafts screwed deep into the ground, can add support to or replace foundations damaged by uneven settling, cracking or heaving, so they're worth asking about if that's what you're seeing.
What causes a house foundation to crack or heave?
Swelling soil is one cause, because clay soils can soak up water from irrigation or rain and swell with enough force to lift a building and crack concrete. Uneven settling works the other way, when part of the ground under the house drops lower than the rest. When I come out, I look at where the water around your house goes, because that's often part of the answer.
Concrete work that often comes with a lift
Concrete cutting
Need an opening in a slab, a damaged section taken out, or room made for new footings? Clean saw cuts remove what has to go and leave the rest whole.
Concrete driveway building
If your driveway is cracked, sinking or no longer meets the garage at the right height, a new one poured over a packed base gives you a smooth way in.
