Foundation repair in Fairfield CA - the right fix for what's really behind the crack
Doors sticking or a crack spreading across the wall? I find out what's causing it, and we fix the cause, not just the crack.

Do cracks and sticking doors mean my foundation needs repair?
Foundation repair in Fairfield, CA, deals with a house that has settled unevenly, which can leave doors and windows that won't open, cracks across the walls and real structural damage. At Ironstone Fairfield Concrete and Masonry, I start by finding out whether your crack comes from settling at all, because plenty of them don't.
Settling matters because damage to the structure can weaken how well your house handles wind, an earthquake or just the everyday load of people and furniture. So when a door starts sticking or a crack keeps growing, it's worth having someone look before it gets worse. That doesn't always mean a big job.
The price turns on what's causing the damage and how much of the house it reaches, since sealing a thin crack is a small job and uneven settling means an engineer's plan and a lot more digging. How easy the foundation is to reach matters too, whether it's under a crawlspace, along a tight side yard or behind a finished wall. The schedule mostly waits on an engineer's review and a city permit when the job needs them, then on our crew's calendar. Once I've walked it with you, the estimate tells you what I see, what I think is causing it and what fixing it involves.
- We check the cracks, the doors and windows, and the floors before calling it foundation trouble.
- We repair cracked and crumbling brick, block and concrete foundation walls, including worn-out mortar joints.
- When it's real settling, an engineer's plan comes first, and we build the repair it calls for.

(707) 398-2147Questions Fairfield homeowners ask about foundation repair
These are the questions I hear most when someone in Fairfield calls about cracks or sticking doors. If yours isn't here, ask me when I come out, because I'd rather explain it than have you guess.
Is every crack in my foundation a sign my house is settling?
No, the most common cause of cracking in home concrete is drying shrinkage, the concrete shrinking as it dries, along with temperature changes. One Bay Area home-service article says wider cracks, stair-step cracks in brick or block, and cracks that are wider at one end point to uneven settling, and that those call for a licensed structural engineer's review before any repair. I'll tell you which kind I think you've got when I see it.
How much does foundation repair cost in Fairfield, CA?
I can't give you an honest number until I've seen what's causing the damage, because sealing a shrinkage crack and carrying out an engineer's settlement repair are very different jobs. After I walk the house with you, the estimate spells out what I'd do and what it would cost.
Can we stay home during foundation repair?
Often you can, depending on the repair method. One helical pile maker's guide says these steel screw-in piers suit repair work because portable equipment installs them in tight indoor spaces without heavy machines or vibration, so the building can stay in use with little inconvenience. Whether that fits your house depends on what the engineer's plan calls for, and I'll tell you what to expect before we start.
Who reviews foundation work in Fairfield?
The city's Building Safety Division reviews new construction, improvements and alterations to existing structures, and permits are applied for through the city's BUILD system. When your job needs a permit, we apply for it, keep you posted and meet the inspector, and if we're not sure whether it needs one, we check with the building office before we start. If you'd like to ask them yourself, the division takes calls at 707.428.7451.
How do I check a foundation contractor and its subcontractors in California?
Ask for the contractor's license first, because in California a home improvement contractor is one licensed by the Contractors State License Board. You can also ask the contractor to list any subcontractors with each one's name, contact information, license number and classification, and state law makes the contractor you hire responsible for the project. We're fully licensed and insured, and our work is backed by our satisfaction guarantee.
How do I find out if my Fairfield house is in a liquefaction zone?
Look up your address on the state's Seismic Hazard Zone Map, which shows areas where liquefaction, ground losing its strength in a strong shake, may occur during a strong earthquake. Developers of property in a mapped zone may be required to study and reduce that hazard during local permitting, but what I've read doesn't settle which Fairfield properties fall inside one. It's worth checking alongside the cripple wall question above.
