Foundation raising in Vallejo CA - your home lifted and set on new concrete
Thinking about raising your house or replacing the foundation under it? We start with an engineer's look, then build the new concrete below.
What does it take to raise a house in Vallejo?
Foundation raising in Vallejo, CA means separating your house from its foundation, lifting it on hydraulic jacks and holding it on temporary supports while a new or extended foundation is built underneath, so your home ends up sitting on fresh concrete.
Most people asking about this want their house sitting higher than it does now, and the first thing I want to know is what's under it today. Depending on its condition and how much more weight it can carry, the old foundation gets either extended or torn out and rebuilt, and that choice decides how much new concrete the job takes. The price also moves with how far the house goes up and what repairs turn up once things are open, while the schedule turns on preparation, permits, the foundation type, inspections and weather. Your own figures come in the written estimate after I've seen the house.
How we handle foundation raising, one stage at a time
Raising a house is a big structural job, so the first step is having a structural engineer look at whether yours can be raised at all, and nothing gets dug until that answer is yes. If it is, we handle the concrete work under the house as part of the team. Once the house is up on its supports, our crew digs out and packs the subgrade, the soil the new footings sit on, then sets rebar, the steel bars that give concrete the strength it doesn't have on its own, builds the forms and pours. Then comes curing, the wait while the concrete gains strength before it takes the weight of your house. The digging and packing are hidden the day the house settles onto them, and they're the first thing people want to trim from a budget, but I won't, because the whole house rides on them, the same way a barn is only as sound as the ground under its posts. I explain each stage as we go so you know what's happening to your house.
Some of the connected work happens right alongside the raise. Where old concrete is in the way of new footings, concrete cutting lets us take out just the section we need with a clean edge. When the house comes back down at a new height, the drive often no longer lines up, and concrete driveway building gets the approach meeting the garage again with water running away from the house.
Why Vallejo homeowners call Precision Vallejo Concrete for foundation raising
I come out and run the crew
I look at every job myself, write up the estimate and stay on site running our crew while the work gets done. When your house is up on supports, the person answering your questions is the same one who walked it with you first.
In business since 2017
I started this business in Vallejo in 2017 after learning the trade on crews around the Bay Area, and we work in the cities around it in Solano County and Contra Costa County. You get a crew that's close by and one I built myself.
Licensed and insured before we dig
We're licensed and insured. On a job where your house is sitting on temporary supports, you want the people working under it covered.
Permits checked with your city first
Each city handles permits its own way, so we check with that city's building office before we start. When your job needs a permit, we can take care of the paperwork and plan our work around the city's inspections.
On a house raise, the concrete your home comes back down on matters more than anything you'll see afterward. When you're ready, call (707) 310-8309 or tell us about your house, and have its size and foundation type handy.

Questions before booking foundation raising
How much does it cost to raise a house in Vallejo?
House lifting usually costs about $10,000 to $40,000 per job across the US, and that range is for raising the structure alone, not the new foundation work under it. National averages also go up with a home's square footage, so a bigger house usually costs more to raise. Your written estimate will show what your house needs.
Can my house be raised?
Usually yes if it sits on a basement, crawlspace or open foundation, since FEMA's guide says lifting works well for those. A slab-on-grade house, one built right on a slab poured on the ground, is often not practical to raise with the slab intact. That's why the engineer's review comes first.
How long does raising a house take?
The whole process takes about 4 to 8 weeks on average, and the lift itself is 2 to 7 days of that once preparation is done. Plan on several weeks of work, with the lift a short part of it.
Who is licensed to raise a house in California?
The state licensing board's building moving and demolition class covers contractors who raise and lower structures, including their foundations. That class leaves out altering, adding to, repairing or rehabilitating the parts of the house that stay in place. On a raise, we handle the concrete under the house as part of the team.
Does raising a house in Vallejo make it riskier in an earthquake?
It can, because FEMA notes that elevating a home can make it more likely to be damaged in an earthquake, so that risk belongs in your decision. In California, cities and counties run building permits and have to use the state's mapped Liquefaction Zones when they do, and in those zones the soil under a foundation has to be investigated and countermeasures built into the design. You can see whether your address sits in an earthquake fault zone, a seismic hazard zone or both with the state's EQ Zapp tool.
How do I get my house ready to be raised?
You empty the crawlspace or basement and have all the utilities disconnected, including plumbing, electric, gas, heating, cooling, phone and internet. Everything inside the house can stay where it is, though staying inside the home while it's lifted isn't recommended.
Other concrete work around a raised house
- Concrete cutting
Sometimes the old foundation or a slab has to be cut cleanly before new footings go in, and a saw cut leaves straight edges instead of broken chunks.
- Concrete driveway building
Once your house sits higher, the driveway may not meet the garage or carry water away the way it used to, so a new one can be poured to match.
