What can decorative concrete do for my patio or walk?
Decorative concrete in Fremont gives a patio, walk or driveway color or a stamped pattern. We either pour it new or lay an overlay, a thin cement-based layer, over the slab you already have, so you can get the look without tearing anything out.
Most people call us with a slab that works fine but looks tired, or with plans for a new patio they want to look like more than gray concrete. The price moves with the size, with whether we overlay or pour new, with the pattern and color you pick, and with how much base work and steel the ground needs. The schedule mostly turns on whether the old slab comes out, because tear-out and a new base take longer than an overlay, and on the weather on pour day. When the budget gets tight, the base is the first thing people want to cut because nobody sees it on day one, and I'll steer you to a simpler pattern before I skimp on what's under it. Once I've seen the job, I'll put your number and the work in writing, and if a pressed-in pattern is what you're after, our stamped concrete page goes deeper.
How do you know your concrete is ready for a decorative finish?
Plain slab, still solid
Your patio or walk is flat and the cracks aren't spreading, but it looks plain or worn. That's the kind of slab an overlay is made for, and getting to it before the surface starts chipping keeps that option open.
Cracks that keep spreading
If cracks widen, sections sink or one edge sits higher than the next, the ground under the slab is moving. Color won't hide that, and an overlay on a moving slab cracks right along with it, so the longer it goes, the more of it has to come out.
Stamped color gone dull
An older stamped patio that looks chalky or darkens and soaks up water when you hose it has usually lost its sealer. Left alone, water and stains get into the surface and the color keeps fading, and faded color is harder to bring back than it is to protect.
How we do decorative concrete
First I check whether the slab you have is worth keeping, because not every old slab has to come out. If it's flat and the cracks aren't moving, we clean it, repair it and lay an overlay that carries the color or pattern. If it's sinking or broken, we take it out and dig down to the subgrade, the dirt the slab sits on. Then we pack a real base, check where the water will run so the new slab doesn't fall toward the house, and set the steel and forms. We set the pour for the cooler part of the day, because heat and wind dry the top before we can color, stamp and finish it, and a rushed top turns weak and dusty later. Then we cut control joints, shallow cuts that give the slab a place to crack where we chose instead of across your pattern, and we seal it once it's cured.
Decorative work often sits next to other concrete. If your patio steps down a slope, a concrete retaining wall holds the soil back so it doesn't push on the new slab. If you want the look inside the house or shop, concrete floor installation gives you a level slab built to take a finish.

What happens after you call about decorative concrete in Fremont?
Here's how a decorative job runs from your first call to cleanup, and who you'll be dealing with at each step.
Call or send the form
Call (510) 574-8512 or use the form, and we'll set a time for me to come out. It helps to have the rough size, new pour or overlay, the finish and color you like, and whether the work reaches the sidewalk.
I come out and measure
I look at the slab and the ground around it, measure it and ask what you need it to do. That's when we see where the water runs and what the base will need.
Read your written estimate
You get the price in writing with the base, steel and joints spelled out, so you can compare it line by line against other quotes. If the job needs a permit, we sort it out before we dig.
We pour, finish and clean
Our crew does the prep and the pour with me on site, and we clean up before we leave. I'll tell you when you can walk and drive on it, because curing, the slow hardening that gives concrete its strength, can't be rushed.
Why Fremont homeowners call Ironset Fremont Concrete
On a decorative job, the color is what you look at, but the base under it decides whether the pattern stays in one piece. If you want yours looked at, ask for an estimate or call (510) 574-8512.
The owner measures and stays on site
I come out to look at the job myself, and I'm on site while our crew does the prep, forms, pour and finishing. The person who priced your slab is the one watching the base go in.
Licensed and fully insured business
We're licensed and fully insured. You're not the one carrying the risk while a crew and a loaded concrete truck are working on your property.
Most calls come from Fremont neighbors
I learned this trade fixing slabs other people got wrong, and I made it a full business in 2021. Most of our calls now come from Fremont homeowners and their neighbors who saw our work.
Decorative concrete and the work around it in Fremont
A lot of ground around here is clay that swells when it's wet and shrinks when it dries. One analysis puts about 37% of Alameda County's soil area in that high shrink-swell group, which doesn't tell you about your lot, but it's why we dig and check before we pour. A California engineers' guide generally recommends rebar, the steel bars that hold a slab together, in slabs on ground that heaves or settles, along with control joints so separations fall along the joints instead of across the part you look at. A reinforced slab does cost more per square foot than one without steel, and on clay that's money I'd rather you spend than skip. We see the same kind of ground on jobs in Newark and Union City.
If your new walk or driveway reaches the sidewalk, curb or gutter, that's work in the public right-of-way, and Fremont requires an encroachment permit for work there or in public easements. The city's list names curb, gutter and sidewalk work and doesn't mention decorative concrete, so it doesn't settle whether decorative work set back from the street needs a permit, and the city is the place to ask. Under that permit, the holder calls USA Underground Alert two business days before work starts and the city inspector at least one day before. When a job needs a permit, we work with the city or county office that covers your address and handle the paperwork and inspections.
Questions about decorative concrete in Fremont
How much does a stamped concrete patio cost near Fremont?
A stamped concrete patio in San Francisco usually costs about $10 to $20 per square foot, and that's the market figure there, not our price. Where yours lands depends on the size, overlay or new pour, the pattern and color, and how much base and steel the ground needs. I'll put your number in writing after I've seen the job.
How often does stamped concrete need to be resealed?
Reseal stamped concrete when it needs it, not on a set calendar. Resealing is the most common upkeep, and the time to do it is when the water or stain protection or the depth of the color starts to fade. Resealing every year just for shine leaves a build-up that can be slow and costly to remove.
What is the best sealer for stamped concrete?
A penetrating water repellent sealer is a good pick when protection is the goal, because it keeps water and stains out of the surface. Most of them add no richness to the color, though, so if you want the color to look deeper, we'll talk through a different sealer at the estimate.
What is the best way to color concrete for an outdoor patio?
For outdoor concrete, skip dyes, because some fade in direct sun and aren't recommended outside. Integral color is usually mixed in at the ready-mix plant, so the contractor has less control over it, and the mix itself can shift the shade. On a bigger patio, an even color is harder to keep, which is worth weighing when you compare color methods.
Which license does a concrete contractor need in California?
California's Contractors State License Board lists the C-8 Concrete Contractor license for forming, pouring, placing, finishing and installing flat and other concrete work. Ask any contractor you're comparing which license they hold before you sign.
How do I know if someone can do a small concrete job without a license in California?
California's minor work exemption now covers jobs up to $1,000, up from $500, and only when the work needs no permit. It also applies only when the unlicensed person employs no one on the project, so on a small job ask whether they're bringing a helper.
Related concrete work you might need
Concrete retaining walls
When a new patio meets a slope, a retaining wall holds the grade back so soil doesn't push against the slab or wash across the finish.
Concrete floor installation
For a garage, shop or room addition, a properly poured floor gives you a flat, sound slab that can take color or another finish later on.
