Stamped concrete services in Sierra Madre CA - a patterned slab built on a solid base
Tired of a plain gray patio that's cracked or dull? We pour, stamp and seal a new slab in the color and pattern you pick.
What is stamped concrete, and what goes into doing it right?
Stamped concrete is a regular poured slab that our crew presses patterns and texture into with rubber stamps while it's still wet, so the design is set into the surface instead of laid on top. At Cornerstone Sierra Madre Concrete, we do stamped concrete services in Sierra Madre for patios, driveways and walks that look like stone, brick or slate but go in as one slab.
Most people call us because their patio or driveway is cracked, uneven or just plain gray, and they want more than a basic concrete patio without laying pavers. The price moves with the size of the area, how much old concrete has to come out, how much base work your ground needs, and how busy the pattern and color are. The schedule turns mostly on the weather and the curing wait before you can walk or drive on it, plus any permit if the work reaches the street, and I'll give you your own figure once I've seen the ground.
How we handle stamped concrete, start to finish
Before anything gets poured, I look at where water runs across your yard, because a slab that falls toward the house sends every rain at your foundation. Our crew digs out the soft dirt and packs the subgrade, the ground the slab sits on, and then a gravel base over it, since a pattern is only as good as what's under it. We set forms, place rebar where the slab needs it so the steel holds the concrete together if it ever cracks, and we pour early in the day rather than in the afternoon heat, which can dry the top too fast and leave it weak and dusty later. Then comes color. I'll explain the difference between color hardener, which is spread on the fresh surface, and integral color, which is mixed through the whole load, and I'll tell you which one I plan to use on your job and why. We stamp the pattern while the slab is wet, cut control joints, shallow grooves that give the slab a planned place to crack, and let it cure, keeping it covered and damp so it gains strength instead of drying out. After we seal it, I'll help you judge when it needs resealing by how the surface is holding up, and I plan the joints, base and curing as carefully as the pattern itself.
A stamped patio or driveway usually meets other concrete, and it looks best when the pieces are planned together. We handle concrete sidewalk building for the walk that ties into it, stamped to match or left plain, and garage floor concrete when a stamped driveway runs up to a garage slab that's worn out too.
Why Sierra Madre homeowners call Cornerstone Sierra Madre Concrete for stamped work
The owner writes your estimate
I come out myself to look at the job and write the estimate, and I'm on site running the crew when we do the work. The person who heard what you wanted is the one watching the stamps go down.
Licensed and insured on every pour
We're fully licensed and insured. Ask to see it when I come out, because it's a fair thing to check with anyone who's going to work on your property.
Street staging sorted out first
In Sierra Madre, putting a container, materials or equipment on the street or sidewalk generally needs a review by the city's Public Works, and it may need an Excavation & Encroachment Permit too. We look into what your job needs from the city or county before work starts, and when a permit applies, we handle the application as the licensed contractor and walk you through each step.
Learned on valley crews first
I spent years on concrete crews around the San Gabriel Valley before I started this business in Sierra Madre in 2020. Those years taught me that the parts you can't see after the pour, the base, the drainage and the joints, decide how a slab holds up.
With stamped concrete, the pattern gets all the attention, but the base, the joints and the curing decide how it looks years from now. When you're ready, send us a few details or call (626) 828-0332, and I'll come take a look.
Get a free on-site estimate for your stamped concrete
Send a few photos, the rough size of the area, any color ideas, and whether the work reaches your driveway approach or the sidewalk. We'll get back to you within one business day, and I'll come out myself to look at the job and write the estimate. It's free, and there's no obligation to book.

Questions before you book stamped concrete
How much does stamped concrete cost in Sierra Madre?
There's no fair number to quote without seeing your ground, so I price each stamped job at a free estimate on site. If the budget's tight, I'd rather simplify the pattern or go with one color than skimp on the base, because the base is hidden on day one and it's the first thing to give when it's cut. Call (626) 828-0332 to set up a visit.
What causes stamped concrete to crack, and how do I prevent it?
Most concrete cracks come from how it was built, such as poor joints, poor base preparation, too much water in the mix, poor finishing and too little curing. That makes each installer's plan for joints, base work and curing a fair way to compare bids, so ask every contractor about it, us included. Joints won't stop every crack, but they decide where one goes.
Should I choose color hardener or integral color for stamped concrete?
One pigment maker says color hardener, spread on the surface, makes a denser, more durable top than integral color, which is mixed all the way through. It takes more finisher time and skill, and hardener that's put on poorly can later peel away in layers with weather and wear, so ask any crew how often they use it. Because it goes on top, hardener can also color separate parts of one project without ordering different batches of concrete.
How often should I reseal stamped concrete?
Reseal when the surface tells you to, mainly when water and stains stop beading off or the color starts to look flat. Resealing every year just to keep a high gloss can cause problems, and so can putting on too much sealer or putting it on too early, since most stamped concrete gets a film-forming sealer that sits on top and shows a heavy or rushed coat. If the area gets wet, one concrete guide suggests asking about a nonskid additive mixed into the sealer.
Do I need a permit from Sierra Madre to redo my driveway approach?
Yes, the City of Sierra Madre requires a permit to dig or build in its street, curb or sidewalk, and its list names the driveway approach, the stretch where your driveway meets the street. That list doesn't name stamped concrete on its own, so tell us at the estimate whether your work reaches the approach or the sidewalk, and we'll look into what it needs.
What license does a concrete contractor need in California?
California's C-8 Concrete Contractor classification covers contractors who form, pour, place, finish and install pavement, flat and other concrete work, which is where stamped patios and driveways fall. Ask anyone you're considering which classification they hold, and you can look it up with the state licensing board.
Concrete work that often goes with it
- Concrete sidewalk building
If your walk to the door is heaved or cracked, a new sidewalk can carry the patio's pattern or stay plain and brushed for grip in the rain.
- Garage floor concrete
When the garage slab is pitted, stained or sloping wrong, a new floor gives you a solid surface for cars and storage, and it can meet a stamped driveway cleanly.
