Concrete Resurfacing & Overlays in Walnut Creek CA - a fresh surface on your old slab
Driveway, patio or garage slab looking worn, pitted or stained? We check it first, then put a fresh layer over a sound base.
Can worn concrete be resurfaced instead of torn out?
Concrete resurfacing and overlays in Walnut Creek, CA, put a new layer of concrete, called an overlay or topping, on top of the slab you already have, so you get a fresh surface while the old slab stays in place underneath.
Usually it's a driveway, patio, walk or garage floor that's gone rough, pitted or oil-stained while the slab under it still seems solid, and you'd rather not pay to break it out and pour new.
The price mostly follows the size of the area and the condition of the slab, since loose concrete, moving cracks and old coatings all add prep before the overlay goes on. The schedule turns on that prep and on the weather, and after I've looked at your floor you get a written estimate with your own figure.
- Driveways, walks, patios and garage floors that look tired but still sit on a solid slab.
- Joints in the new layer should sit right over the old slab's joints instead of being buried.
- Oil-stained garage and driveway slabs get cleaned first, because the overlay bonds best to a clean base.
What happens when you call us about resurfacing in Walnut Creek?
I like to see a slab in person before anyone talks price, because what's under the stains decides the job. Here's how it goes from your first call to the walkthrough at the end.
Call or send us a message
Call (925) 433-7858 or send the form, and tell us where the slab is and what's bothering you about it. We get back to you to set a time, and photos of the cracks and any oil stains help me come ready.
I check your slab in person
I come out myself and look for moisture, old coatings and cracks, especially any that are still moving. Then I walk you through what I see and which overlay, if any, fits your slab.
Get a written estimate
You get the price in writing, based on what I found, before anyone starts grinding. If the slab needs crack repair or extra prep, that's in the estimate, so you know what you're paying for up front.
We prep, resurface and review
Once you say yes, our trained installers do the prep and place the overlay with me on site. Before we pack up, we go over the finished surface with you.

(925) 433-7858Common questions about resurfacing concrete in Walnut Creek
These are the questions homeowners ask me most when they're thinking about resurfacing. If yours isn't here, ask me when I come out to look at your slab.
How do I know if my concrete slab can be resurfaced?
A slab can usually be resurfaced if it's sound underneath and its cracks aren't still moving, or can be stabilized first. A thick slab that's badly worn may still take a thicker overlay. That's the first thing I check when I come out.
How much does concrete resurfacing cost in Walnut Creek?
It depends on your slab, so I give you a figure in a written estimate after I've seen it, not a number over the phone. The biggest factors are the size of the area, how much loose concrete and how many moving cracks need work first, how much oil and old coating has to come off, and whether a thin overlay will do or a thicker one is needed. A cleaner, sounder slab takes less prep, and that shows in the price.
How long does resurfaced concrete take before I can walk or drive on it?
With one maker's resurfacer, people can walk on it in as little as 2 to 3 hours and cars can drive on it in 4 to 8 hours. Other products have their own times, so I'll tell you what the one on your job calls for, which helps you plan where to park that day.
What is the best time of year to resurface concrete in Walnut Creek?
Mild, dry days are best, because one maker's guide says its resurfacer should go on out of direct sun, not on hot or windy days, and above 50°F for 48 hours. That guide also asks for rain protection for at least 4 hours, so we watch the forecast and move the date if the weather turns.
Does a contractor need a license to resurface concrete in California?
Yes, for nearly any real resurfacing job, because California only lets an unlicensed person take on work under $1,000 that needs no permit, and that person can't hire anyone to help. Walnut Creek also asks that every contractor and subcontractor on an encroachment permit hold a city business license. We're fully licensed, and you're welcome to ask to see it.
Is the dust from concrete resurfacing harmful?
It can be, since one maker warns that breathing the silica in its product's dust may lead to lung disease, including silicosis and lung cancer. It's fair to ask any crew how they handle dust while they work, and I'll walk you through how we do it.
Concrete resurfacing and overlays in Walnut Creek and nearby cities
Work at the street edge, like the driveway approach or front sidewalk, needs a Walnut Creek encroachment permit, and the city's no-permit list doesn't mention resurfacing, so we check with the city first. We check the same way in Concord, Lafayette and other cities nearby.
