How can you tell your concrete needs sealing?
Bare concrete soaks up whatever lands on it, so if you catch these signs early, a simple seal is usually enough and you can skip a bigger repair later.
Oil spots that soak in
Drips from the car sink into bare concrete and leave dark spots that scrubbing won't lift. The longer the slab stays unsealed, the deeper each new drip sets in.
Dust that keeps coming back
If you sweep and fine gray dust shows up again a few days later, the top of the slab is wearing down, and that wear usually spreads if it's left alone.
Stains you can't scrub out
Spilled drinks, rust from tools and wet leaves leave marks that stick. Unsealed concrete takes in stains easily, so every spill adds another one you'll be looking at.
Water darkens it right away
Splash some water down, and if the concrete turns dark fast and stays that way, it's soaking the water in. Sealing helps the surface stand up to the weather.
Hairline cracks that keep growing
A crack that's widening or chipping at the edges lets water and dirt into the slab. Small cracks are usually a quick repair, and waiting just lets them grow.
Scuffs and tire marks
Hot tires, dragged tools and moved furniture scuff bare concrete, and the marks build up over time. A sealed surface stands up better to scuffing and cleans up easier.
How we handle concrete sealing in Oakley
Sealer won't close up cracks, and a coat over an open crack still leaves water a way in, so we repair the cracks before anything else. Then our crew cleans the slab down to sound concrete and keeps the wash water out of the storm drain, since Contra Costa County says that water has to stay out and holds you responsible for what your contractor washes into it. We wait for a dry day because the seal has to bond to a dry surface. One sealer maker says not to put its product on damp concrete or when rain is expected within 12 hours, so a wet forecast can move our start date. Some film sealers dry to a glossy finish that changes how the slab looks, so I'll talk through the look you want before we pick one. The price moves with the size of the slab, how many cracks need repair and how much cleaning it takes. The schedule turns on the forecast and how old the concrete is, and your written estimate spells out each step.
Sometimes a seal isn't the right fix, and I'll tell you so at the estimate. If the slab is pitted, flaking or worn past what a sealer can cover, concrete resurfacing and overlays give you a fresh top layer to seal. If the floor dips or slopes, self-leveling concrete evens it out before anything goes over it.

Concrete sealing questions
These are the questions that usually come up when someone's thinking about sealing their concrete. If yours isn't here, call or send the form and tell us about your slab.
How much does concrete sealing cost per square foot in Oakley?
Professional concrete sealing usually costs about $1 to $2.50 per square foot across the US, with labor and materials included. That's a national figure, not our price, and crack repair, cleaning and the sealer you choose all move your number. I'll measure the slab and send a written estimate that lays out each step. Satisfaction guaranteed on every job.
Can I seal a brand new concrete slab?
Not right away, because new concrete needs time to cure, or harden, before it's sealed. One sealer maker's guide says to wait a minimum of 28 days, so if you've just had a slab poured, we book the sealing as its own later visit.
Will sealing stop water coming through cracks in my concrete?
No, sealer isn't a crack fix. One maker says its sealer isn't meant to waterproof concrete and won't block water moving through cracked or poorly repaired surfaces, so crack repair goes on your estimate as its own step.
Do I need a permit to seal concrete in Oakley?
Ask the city before work starts, because the Oakley Building Division issues permits and asks owners to contact it first to confirm whether a project needs one. The city only issues permits to the property owner, an agent the owner authorizes or a contractor licensed by the state board. We check with the office that covers your address before we start, and if a permit is needed, we can pull it as your licensed contractor or help you apply yourself.
How long do I have to stay off concrete after it's sealed?
One maker says to keep foot traffic off its film sealer for at least six hours, so plan on the area staying closed for a while. Other sealers set their own times, and we'll tell you the one for the product on your slab before we leave.
What causes sealed concrete to peel or turn white?
Usually it's poor adhesion or moisture trapped under a film sealer, which can make the film peel or turn cloudy white, called blushing. That's why the surface has to be dry and ready to bond on sealing day, and an old coat that's already failing usually has to come off first.
