San Marino homes and what they mean for concrete
San Marino is almost all houses. Most of our calls here come from quiet residential streets with larger lots, older homes next to careful remodels, and long driveways that run back to the garage, with front walks and back patios under trees that have been growing for decades. It feels a lot like the older blocks of South Pasadena and parts of Pasadena, and the concrete we find is much the same.
That shapes the job before anything gets poured. Original slabs usually have to be broken out and hauled off, roots have to be dealt with where they've lifted the old work, and a long driveway means planning how the truck reaches the far end without crossing your lawn.
Concrete work we do for San Marino properties
Concrete driveway building
Long driveways on San Marino's larger lots often sit on old, root-lifted slabs, so we break them out and rebuild on a dug-out, packed base.
Concrete patio construction
Back patios here usually sit under big trees and beside older foundations, so we set the slope away from the house before anything gets poured.
Stamped concrete services
When a period-style house calls for something closer to stone or brick, stamped concrete gives the patio or walk that pattern, with joints planned into the design.
Concrete sidewalk building
Front walks and garden paths on older lots heave where roots run under them, and we replace the lifted sections so the edges line up again.
Garage floor concrete
Garages behind older San Marino homes often have thin, cracked original floors, and we pour a new slab with steel where the car and storage load it.
Decorative concrete
Colored or exposed-aggregate finishes suit the gardens and courtyards on larger lots here, and we pick the finish with you for grip as well as looks.
Concrete retaining walls
Where a yard steps down toward the street, a poured wall on a proper footing holds the soil back and leaves a level lawn or planter above.
Concrete floor installation
For a converted garage, studio or pool house here, we pour an interior floor flat enough for the tile or wood going on top.
Concrete pool decks
Decks around older backyard pools here often crack or pull away from the pool edge, so we rebuild them sloped to drain, with a surface that grips wet feet.
Concrete steps construction
Entry steps on older homes settle and crack away from the porch, and we rebuild them with every step the same height so nobody catches a toe.
Slab foundation building
For a new guest house, garage or addition here, we lay out and pour the slab to the approved plans, checked before the truck arrives.
Foundation installation
Additions and rebuilds on older houses here need a foundation that ties into what's already there, and we form and pour it to the engineer's plans.
Concrete parking lot building
Church, school and small office lots in and around San Marino need slabs thick enough for daily traffic, with drainage laid out before the pour.
Concrete footings
Garden walls, pergolas and new posts on larger lots need footings, the concrete pads that carry the weight, dug to depth and poured to plan.
Foundation raising
When an older house has settled at one corner and doors start sticking, we raise and support that section of foundation instead of starting over.
Concrete cutting
We saw-cut a clean line through an old driveway or patio so a lifted section can come out and the slab you're keeping stays put.

Working in San Marino: permits, licenses and pricing
Permits for concrete work in San Marino go through the city's Planning and Building Department, where the Community Development Director serves as the Building Official. When your job needs one, the pour waits until it's issued, so we file the application, keep it moving and tell you where things stand with the city. Before you hire anyone, ask about two licenses. One is a state license from the Contractors State License Board. The other is a current San Marino business license, which a contractor has to renew every year before starting work in the city and which carries their state license number. The city's Business License Department answers questions about those licenses at (626) 300-0700. We're licensed and fully insured.
What moves the price here is mostly what the photos don't show, like how much old concrete comes out, how far the truck can reach up a long driveway, how thick the slab is, how much steel goes in and how much digging the base takes. The base, or subgrade, is the packed ground the slab sits on, and because it's buried on day one it's the first thing people want to cut. I'd trim the fancy finish before I'd trim the base, because a good surface on loose fill sinks right along with it. The schedule turns on the permit, if there is one, and on curing, the days new concrete needs to gain strength before it takes foot traffic and then a car. Your written estimate puts a line on each of these. It's the same work we do in San Gabriel and back home in Alhambra, and San Marino's quiet streets just mean we plan where the truck parks and leave the curb clean.
Older San Marino slabs and why they fail
Many houses here still have their original driveways and walks, and by now they show it, with slabs lifted where roots pushed under, sections sunk where the dirt settled, and puddles that sit against the garage or run back toward the house. A lot of that older work went down on raked dirt with few control joints, the straight cuts that give concrete a planned place to crack, so the cracks wandered wherever they liked. We dig out to firm ground, pack the base, set the slope so water runs away from the house, and cut the joints before the slab can crack on its own.
Caltech's earthquake data center lists San Marino among the communities closest to the Raymond Fault. That listing sets no rule for your lot, but it's one more reason I won't skimp on rebar, the steel bars that hold a slab together, or on footing depth when the plans call for them.
How a concrete job runs when you call us from San Marino
Here's what happens from your first call to the final walk-through, and who you'll be dealing with at each step.
Call or send the form
Call (626) 597-0288 or use the form, and we'll set a time for me to come out. It helps to know roughly what you want poured and what it has to carry.
I measure and write it up
I come out myself, measure, and ask what the concrete has to carry and what's going on top of it. You get a written estimate that lists each part of the job, so you know what you're paying for and can compare bids line by line.
Our crew forms and pours
Our crew sets the forms, packs the base, pours, and puts on a broom finish, a light brushed texture that gives shoes and tires grip, then cuts the joints. I'm on site on pour day checking the work as it goes.
We walk the finished job
When we finish, I walk the job with you before we call it done. I'll also tell you when the slab has cured enough to walk on and when it's ready for your car.
Questions about concrete work in San Marino
What building code does San Marino use for concrete work?
San Marino uses the California Building Code, adopted into city law along with some local changes of its own. The Planning and Building Department keeps the code for the public to look at, and you can read the city's building code adoption online. Where your job falls under it, we pour to plans that meet it.
How do I know if my concrete job in San Marino needs a licensed contractor?
The state requires a licensed contractor when a project needs a building permit, uses hired workers, or adds up to $1,000 or more across its contracts. A bigger job can't be split into smaller contracts to get under that line. Licensed contractors also have to show their license number in ads for that work, so look for it.
How much can a concrete contractor ask for as a down payment in California?
The state caps a home improvement down payment at $1,000 or 10 percent of the contract price, whichever is less. Any other payments have to be spelled out in the contract and tied to work done or materials delivered. That rule covers a driveway or patio the same as any other home project.
Can I pour my own patio in San Marino without a contractor's license?
Yes, the state exempts homeowners improving their own principal residence, as long as you've lived there for the 12 months before the work is finished and it's done before a sale. You can use that exemption on no more than two structures in any three-year period.
How much does a new concrete driveway cost in San Marino?
The cost comes down to the driveway's size and thickness, how much old concrete has to be broken out and hauled away, and the finish you choose. A plain broom finish costs less than stamped or colored work, and roots under the old slab or a long reach for the truck add labor. Your written estimate lists each part, so you can see where the money goes.
What causes cracks in concrete driveways in San Marino?
Most cracks we see here come from tree roots pushing up, a base that was raked level instead of dug out and packed, and joints that were cut late or skipped. Water running toward the house instead of away softens the ground under the edges too. No one can promise concrete won't crack, but a packed base, the right slope and joints cut on time keep cracks small and in lines we chose.
