Does my house need foundation raising, and what's involved?
Foundation raising lifts the sunken part of your Concord house back toward level and rests it on support meant to keep it from sinking further, so the floors, doors and walls line up again.
Most people call me after they've watched a crack for a while and started wondering whether it's the house or just the paint. The price and the schedule come down to things you can't see from inside: whether the house sits on a slab or over a crawl space, how many piers it needs, how hard it is to dig along the walls, and what has to change so it doesn't settle again. A permit can add time when the work moves soil, and we handle that paperwork when one's needed. I'll go through all of it at your house and put the figure for your job in writing, so you know what you're paying for before you decide.
How do you know if your foundation has settled?
Doors that won't latch
A door that used to close fine now rubs at the top corner or won't catch, because the frame has gone out of square as one side of the house dropped. Waiting usually means planing doors that keep sticking while the house keeps moving.
Cracks that keep growing
Diagonal cracks off the corners of doors and windows, or stair-step cracks in brick, that are longer this year than last usually mean the settling is still going on. The longer it runs, the more wall there is to patch once it stops.
Floors that slope
You feel a dip walking across a room, or furniture rocks on a floor that used to be flat, which usually points to one corner or a few piers sinking. Left alone, the low side tends to keep going, and the lift gets bigger.
How we handle foundation raising, start to finish
I start by looking for what made the house settle, because lifting it doesn't help if the cause is still there, and most often that's water, like a downspout emptying against the wall or a yard that drains toward the house. Once we know the cause and whether you have a slab or a crawl space, we plan the lift, dig where we need to reach the footing, set the support, bring the low side up a little at a time while we watch the doors and cracks inside, then backfill and clean up. Before any of that starts, the written scope says what's ours and what isn't, like patching drywall and paint, so nothing about the finish surprises you later.
A foundation job often runs into the concrete around the house. When a pier has to go under a patio, walk or garage slab, we use concrete cutting to take out a neat section and pour it back, instead of breaking up the whole slab. If the driveway sank with the house or has to come out for access, we can replace it as part of our concrete driveway building work once the house is steady.
Houses over a crawl space
On a pier and beam house we can reach the framing from underneath, so leveling usually means shimming the low spots or replacing piers that have sunk. It's the lighter of the two jobs, with less digging outside.
Houses on a slab
There's no getting under a slab, so it has to be lifted on piers set down to soil that can carry the load, which means noisy digging along the outside of the house. That extra work is why slab jobs cost more.

I look inside and out with you and track down what made the house settle before I talk about lifting it. You get a written estimate that covers the work, how we'd deal with the cause and what's outside our scope.
Sort out permits, then lift
Once you've decided, we take care of the city or county side and then do the work, with me on site the whole way. I'll tell you before each stage that affects you, like digging along a wall or lifting the floor you walk on.
Walk the finished job together
When the house is up and the ground is filled back in, I walk it with you and we check the doors, floors and cracks you showed me at the start. We go back over the written scope so you know what's finished and what's left for your painter.

Foundation raising and permits in Concord
In Concord, the city's Engineering Division issues separate grading and encroachment permits when a project moves soil or works in the public right-of-way, the strip along the street that belongs to the city. Digging along a slab to set piers can move soil, but whether your job needs those permits, or any other, depends on the work at your address, so we check with the city or county that covers your house and handle the paperwork when a permit is needed. If you'd like a look first, the city's Project Pal tool shows which permits a project calls for and estimates the fees.
The Concord-Green Valley Fault runs under the city, though that by itself tells you nothing about any one house. What I go by is what I find at yours, and we see the same mix of slab houses and older homes over crawl spaces on jobs in Pleasant Hill and Martinez.
Questions about foundation raising in Concord
How much does foundation raising cost in Concord?
House leveling across the US usually costs about $3,500 to $30,000 per job, according to a 2026 cost guide, so that's a national range and not a Concord quote. Underpinning is priced per pier, with different rates for steel push piers and helical piers, so the number of piers your house needs moves the total a lot. I'll put the figure for your house in writing after I've seen it.
How long does foundation raising take, and can I stay in my house?
You can usually stay in your house the whole time, so plan on some workdays at home rather than a move. One cost guide puts pier and beam shimming at 1 to 3 days and slab underpinning at 3 to 7 days, depending on how many piers go in, and one helical pier maker says its piles go in without vibration so the people inside are barely disturbed.
Will leveling my house fix the cracks in my walls?
Leveling stops the cracks you have from getting worse, and lifting can partly close some of them, but it won't patch them. One cost guide says most contractors leave drywall, trim and paint repair out of their scope, so budget for a painter or drywaller once the house is back up.
What is underpinning, and when does a house need piers instead of shims?
Underpinning keeps a foundation from settling further by moving the house's weight down to deeper ground that can carry it. Settling that's still going on calls for piers, and shimming it instead tends to mean leveling again later, so ask any contractor which one your house needs and why.
What causes a house to need leveling again after it was already fixed?
A properly leveled house on stable soil shouldn't need it again, so a repeat job usually means the cause was never fixed. The usual culprit is drainage that keeps soaking the ground under the house, which is why it's worth asking any contractor what made yours settle before they talk about lifting.
How can I tell if my house is on a slab or pier and beam?
If there's a crawl space hatch, vents low on the outside walls and floors that sound a little hollow, it's pier and beam. If the floor sits right on the ground with no space under it, it's a slab, and either way, tell us which when you call, along with where the cracks are, so I know what to look at first.
