Foundation raising in Castro Valley CA - a steady house with floors closer to level
Floors that slope, doors that stick, cracks that keep growing? We find the cause, stabilize the house and bring the floors back closer to level.

Is your sloping floor a sign the foundation needs raising?
Foundation raising in Castro Valley lifts your house and its foundation so the floors move back toward level and the house is stable again, whether that takes a small correction in one corner or a lift of the whole structure.
Most calls start with something you notice long before you look at the foundation, like a door that won't latch, a crack climbing from a window corner or a marble that rolls to one side of the room. What moves the price is how much of the house has to come up, how far, how easy the foundation is to reach and what it takes to fix whatever pushed it out of level. The schedule turns on that same fix and on whether the job needs a county permit, which we check on early. I'll come out and measure, and your estimate spells out what's included.

Foundation lifts, slabs and driveways
How we handle foundation raising
I start by measuring how far your floors are out and where they fall, then look for what's moving them, usually water around the foundation or the soil under it. Much of the East Bay sits on clay that swells when it's wet and shrinks when it's dry, so a house can read closer to level in March than in September, and I note the season when I measure. Leveling alone tends not to last while that cause is still active, so we plan the fix for it alongside the lift instead of after. I'll tell you up front that the goal is a stable house with floors brought back closer to level, not perfectly flat. Our crew digs along the foundation where the supports go and raises the house in stages, checking the floors as we go. Everything attached to a floor moves with it, so before we start we talk through the drywall cracks and doors that may need rehanging, and the chance that tile cracks or plumbing needs adjusting.
A lift often touches the concrete around the house too. When a slab, walk or patio sits right where we need to dig, we use concrete cutting to open a clean section instead of breaking out more than we have to. If your driveway dropped with the house or sends water toward it, we can replace it with a new concrete driveway on a base that's dug out and packed, sloped to carry water away from the foundation.
Why Castro Valley homeowners call us to raise a foundation
I walk every job myself
I come out, measure the floors and do the estimate myself, and our crew lead runs the lift with our own crew. You hear the plan from the person who made it, and the people under your house are the ones who were told it.
Licensed and insured before digging
We're licensed and insured. A lift means digging along your foundation and putting real load on it, so that coverage matters to you if something goes wrong on site.
Plan and quote set first
We've been in business since 2017, and what I care about most is a job that goes the way we planned it together. The order of work is set before anyone shows up and the estimate says what's included, so the quote matches the job.
Based in Castro Valley
We're based in Castro Valley and work across the cities around it, from Oakland and San Leandro down to Union City and out to Dublin, San Ramon and Pleasanton. The older houses and shifting soil you're dealing with are the kind we work around, so the plan fits your house and not a template.
On a lift, knowing why the house moved matters more than how fast it comes up. Send me your address and what you're seeing, and I'll come out and measure.

Foundation raising questions from Castro Valley
How do I know if my sloping floor needs a foundation assessment?
As a general guide, a slope under 1 inch over 20 feet is within normal range for an older home, while more than 2 inches over 20 feet, or any slope that's measurably getting worse, warrants a structural assessment. Since clay soil shifts floors with the seasons, measure the same spot a few months apart if you can. Send me those numbers with your address and I'll come out and take a look.
Will my house be perfectly level after foundation raising?
Usually not, and on an older house that's the right call. Pulling a floor all the way flat can cause more damage than leaving it slightly out, so most good outcomes stabilize the house and recover part of the slope. I'll tell you at the estimate what I think is realistic for yours.
How much does foundation raising cost in Castro Valley?
It's priced to your house after I measure it, because no two lifts are the same size. Cost moves with how much of the house comes up and how far, how much digging it takes to reach the footing, whether we have to cut through a slab or walk to get there, and what the drainage or soil fix behind it involves. The touch-ups afterward add to it too, so I go through all of it at the estimate.
Who handles building permits for foundation work in Castro Valley?
Alameda County does, because Castro Valley is unincorporated, and its Building Inspection Department takes applications through an online permit portal. We check with the county early, and when a job needs a permit we handle the application and set up the inspections.
How do I check if my Castro Valley home is in an earthquake hazard zone?
Type your address into the state's EQ Zapp map on a phone or computer to see whether it's in a mapped earthquake hazard zone. The state's hazard maps show liquefaction and earthquake-induced landslide zones, and projects on properties in those zones may be required to investigate and address the hazard during local permitting. While I'm looking at your foundation, it's also worth asking about your cripple walls, the short wood walls between the foundation and the first floor, because national guidance warns that weak anchorage can let a house slide off its foundation in an earthquake and poor bracing can let those walls collapse.
Which contractor license covers raising a house in California?
The state license board's building moving and demolition classification covers raising, lowering and underpinning structures, including their foundations. Repairs to the parts of the house that stay in place fall outside that classification, so ask whoever you hire how those repairs get handled.
Work that often goes with foundation raising
Concrete cutting
Clean saw cuts through slabs, walks and patios let us reach the foundation or remove a broken section without cracking the concrete you're keeping.
Concrete driveway building
A driveway that dropped with the house or sends rain toward it is worth replacing once the foundation is stable, on a base dug out and packed.
