Concrete Sealing in Pittsburg, CA - a slab that sheds water and holds its look
If water soaks in, stains sink deep or old sealer is flaking, we clean the concrete and seal it with light, even coats.
Does your concrete need sealing, and what goes into it?
Concrete sealing in Pittsburg, CA puts a sealer on bare concrete that keeps water out and protects it from chemicals and sun, so your driveway, patio or garage floor wears more slowly. Most of the job is cleaning and drying time, and the sealer itself goes on fast.
Most people call us when their concrete has started to look tired, or right after a new pour, and they want it to hold up without looking like a different slab. The price turns on the size of the area, how much cleaning and stain work it needs, whether old sealer has to come off first and which sealer you pick. The schedule turns mostly on mild, dry weather and drying time. You'll get your own figure in a written estimate after I've looked at the concrete. If the surface is cracked, pitted or worn through, sealer won't fix that, and resurfacing the concrete first is usually money better spent. California requires anyone in the home improvement business to be licensed before they even bid, with a narrow exemption for jobs under $1,000 that need no permit and where the worker has no employees on the project, and we're licensed and fully insured.
How do you know your concrete needs sealing?
Bare or worn concrete usually shows you it needs help before real damage sets in. These are the signs owners notice on driveways, patios, garage floors and pool decks that sealing or resealing is due.
Water soaks in and darkens the concrete right away, which means the old sealer is gone or never went down.
Oil drips and spills sink into the driveway or garage floor and won't scrub out anymore.
The surface looks chalky, faded or dusty, usually because sun and weather are wearing down the top layer.
Old sealer is peeling, flaking or turning white in patches, often from heavy coats trapping moisture underneath.
The finish is worn through on walkways and where cars turn, while the edges still look sealed.
You've just had new concrete poured and want it protected before stains and weather get to it.
If water soaks straight in or old sealer is flaking, call (925) 318-8041 sooner rather than later, because sealing protects sound concrete but can't undo damage already done.
What happens when you call us to seal concrete in Pittsburg?
Here's how a sealing job runs with us, from your first call to the day you walk the finished concrete. I'm part of it from the first look to the final walk, and our own installers do the work.
Call or send a message
Call (925) 318-8041 or use the form, and tell us the rough size of the area, what finish is on it now and whether there's a pool deck or slick spot. We'll get back to you and set a time for me to come out.
I look at the concrete
I check the slab for moisture, old sealer and stains, ask how you use the space, and try a small test spot if you're weighing a darker, glossier look. You get a written estimate that spells out the prep, the sealer and the price, so there's nothing to guess at.
We clean, then seal
Our crew cleans and scrubs the concrete, deals with any old coating, and lets the slab dry before any sealer goes on. I'm there for the prep and check in while the sealer goes down.
We walk it together
When it's done, I walk the finished surface with you and tell you how long to keep feet and cars off it. I'll also point out the spots that will wear first, so you know where to look when it's time to reseal.

Sealer types and how we put them down
Sealers come in two broad kinds. Penetrating sealers soak into the concrete and do their work below the surface, while film-forming sealers sit on top as a thin coat that wears where you walk, drive and get sun. For most driveways and patios here I lean toward penetrating, because there's no surface film to scuff or peel, and I save film sealers for owners who want the richer look.
We keep coats light. Piling on sealer, or stacking new coats over old ones that haven't worn away, can trap moisture in the slab and make the sealer lose its grip, and that's how a lot of white, peeling sealer jobs start. Thin, even coats on clean, dry concrete hold better and leave room for a clean reseal later.
Pool decks and other outdoor concrete that gets slick when wet can take a sealer with a slip-resistant additive mixed in, which adds traction along with protection. Inside, sealer won't fix a floor with low spots or ridges, and self-leveling concrete is the better first step there, with a sealer or coating on top afterward.
Concrete sealing questions from Pittsburg owners
How much does concrete sealing cost in Pittsburg, CA?
Your price comes from the size of the area, how much cleaning and stain work it needs, whether old sealer has to come off first and which sealer you choose. A stained driveway with peeling old sealer takes far more prep than a clean patio, and prep is most of the work. I'll look at it and give you a written estimate.
Which concrete sealer keeps my concrete looking the same?
A penetrating sealer is the one to pick if you want your concrete to look like it does now, because it forms its barrier beneath the surface. Glossier sealers can change the look a lot, and one maker says its medium-gloss sealer greatly darkens concrete. That's why we try a small test spot first if you're leaning toward the darker look.
How long does concrete sealer last before it needs resealing?
One maker says its cure-and-seal products last 1 to 3 years, with some peeling and flaking as they wear away, and they wear faster in high-traffic areas and direct sun. That maker advises resealing only after the earlier coats have worn off or been stripped, for the same reason we keep coats light. Our work is backed by our satisfaction guarantee.
Does sealing concrete stop stains?
Sealing can help against stains, but don't count on it to stop them. One maker says its penetrating sealer helps protect against stains, while another says cure-and-seals and penetrating sealers will not prevent stains. Either way, wiping up oil and spills quickly is still your best defense.
How long after sealing concrete can I walk or park on it?
For one penetrating sealer, the maker says light foot traffic can go back on after 4 to 6 hours and furniture and cars after 24 to 48 hours, with a full cure in 72 hours. Those times assume 70°F and 50% humidity, so a cooler or damper day takes longer. I'll tell you what to expect for the sealer on your job.
What is the best time of year to seal concrete in Pittsburg?
Pick a mild, dry stretch, because one maker's penetrating sealer goes on only between 50 and 90°F air temperature, below 85% humidity, out of direct sunlight and with no rain expected within 24 hours. Pittsburg has hot summers and borders on semi-arid because it sits in the Mt. Diablo rain shadow, so summer afternoons can run too hot and sunny, and we plan around shade and the cooler part of the day. That maker also wants newly poured concrete cured at least 28 days before it's sealed.
