Peeling, stained or cracked garage concrete? We repair and prep the slab first, then lay down a coating that has something solid to hold onto.
Garage floor coatings in Castro Valley are layered finishes, usually an epoxy base with color chips under a clear top coat, bonded to your concrete so you get a sealed floor that wipes clean instead of bare concrete that dusts and stains.
Most people call us when the bare slab is dusting, soaking up oil, or the paint someone rolled on years ago is peeling up under the tires. A coating changes how the floor looks and cleans, but it can only hold as well as the concrete under it, so I look at cracks, moisture and any old coating before we talk about colors.
The price moves with the size of the garage and how much work the slab needs first, such as crack repair, stripping an old coating or dealing with moisture. The schedule turns on that same prep, on how fresh the concrete is, and on how long the coating needs before a car can sit on it. Your written estimate spells out both the price and the prep.
Before any coating goes down, a few things about your slab decide how it will hold up. These are the points I'd want you to ask any crew about, ours included.
One coating maker calls surface preparation the most important phase of the job, because a well-prepped slab gives the coating a longer life and fewer failures. Another says the concrete should be roughened by machine, by diamond grinding or shot-blasting, before coating. When you compare quotes, please ask each crew exactly how they'll prep your slab.
One maker requires concrete to cure for at least 28 days before its coating goes on, so the slab has time to dry and harden underneath. If your garage floor was poured recently, that wait comes first, and it's worth planning the coating around it from the start rather than rushing it.
One maker's coating is combustible, so flames, pilot lights and electric motors stay off until the vapors clear and the coating is hard. The garage also needs good airflow while the coating is mixed, applied and cured. If your water heater or furnace sits in the garage, we'll work out how to handle that at the estimate.
Here's how a garage floor job goes with us, from your first call to the walk-through, so you know who you'll be dealing with at each step.
Call (510) 931-7868 or send us the form with a short note about your garage. We'll get back to you to set up a time for me to come out and see the floor in person.
I come out myself, check the concrete for cracks, moisture and any old coating, and ask how you use the garage. Then you get a written estimate with the price and the prep laid out.
Once you're ready, our crew repairs the cracks and joints that need it, preps the surface and puts down the system we agreed on. Please keep cars and stored things out until I tell you the floor is ready.
Before we leave, I walk the finished floor with you, looking at the edges, the joints and the finish side by side. If anything isn't right, that's the time to point it out, and I'll answer any questions you have.
Cracks and joints get looked at before anything else, since a coating can't hold a moving slab together. One maker notes that a coating can crack when the concrete under it moves or separates, so we repair the cracks that need it first rather than coat over them and hope. If a crack is still moving, I'll tell you plainly, even if it isn't what you wanted to hear.
Then we prep the surface and put down the system we agreed on. A common garage system is an epoxy base with color chips under a clear top coat, often a polyaspartic one, and you can read more about polyaspartic floor coatings on their own page. If you'd rather have a smooth, glossy floor with movement in the color, metallic epoxy flooring is the other route.
We keep grinding dust under control and clean up before we leave, because it's your home and it deserves to be treated that way. When the coating is down, I'll go over with you when you can park inside again, so you can plan where the cars and the stored things go for that stretch.
Chips scattered into the base coat hide dust and small marks and add a little grip, and the clear top coat seals them in. For a garage that parks cars and sees wet shoes, this is the one I'd lean toward.
A solid or metallic floor looks smooth and clean, but it shows tire marks, scratches and dust more readily. I'd suggest it when the garage works more as a shop, a gym or a place to show off a car.
We reply within one business day to set up a visit, and the estimate is free, done on site and comes with no obligation. When you send the form, please tell us roughly how old the slab is, whether it has cracks and how big the garage is. I'll then come out, look over the floor and put the price and the prep in writing.
(510) 931-7868Castro Valley is one of Alameda County's unincorporated communities, so building permits here go through the county. You apply, submit plans and schedule inspections through the Alameda County Permit Portal. I won't guess at whether your garage coating needs a permit. If it does, I'll say so at the estimate and file it with the county for you, or walk you through it if you'd rather file it yourself.
State law lets someone without a contractor's license take on only small jobs, now up to $1,000, and only when the work needs no permit and they have no one working for them on the project. Before you hire anyone for your garage floor, it's fair to ask whether that limit really covers what they're quoting, or whether they ought to be licensed.
Around Castro Valley and nearby cities like Hayward and San Leandro, the garages we see are often older slabs with hairline cracks, oil stains and paint or sealer that's starting to lift. We're based in Castro Valley and also work in Oakland, Dublin, Pleasanton and many other cities around it, and the prep is the same wherever the garage is.
I do every on-site estimate myself, and I stay on the job with our crew from the first pass of prep to the final walk-through. That way the person who looked at your cracks is the same person making sure they get repaired properly before the coating goes on.
We've been coating floors since 2017, so this is our ninth year. I started by grinding and coating my own garage and reading every product sheet I could find, and the habit of following the maker's instructions has stayed with me on every floor since. We're licensed and insured.
We offer satisfaction guaranteed on every job. I'd rather tell you what your slab needs up front than have you find out a year from now. If you'd like me to take a look at your garage, please call (510) 931-7868 or send us the form, and thank you for considering us.
If sunlight hits your garage floor through an open door, or you want a hard-wearing clear top coat, polyaspartic is worth asking about at the estimate.
For a garage that doubles as a workshop, a gym or a showroom for a car you care about, metallic epoxy gives a glossy, poured look with swirls of color.
Our crew coats garage floors across Castro Valley and the cities around it. Find yours below, and if it isn't listed, please call and ask, since the list doesn't cover every place we work.
Your price comes down to the size of the garage and how much repair and prep the slab needs before it's coated. Crack and joint repair, removing an old coating and a vapor control layer for a damp slab all add to it, and the system you pick matters too. I put the exact price and prep in writing after I see the floor.
For one coating maker's one-day system, cars stay off for at least 3 days in summer and at least a week in winter, and the wait shifts with conditions. Please plan where to park and store things for that stretch, and allow the longer wait in winter. When we finish, I'll tell you when your floor is ready for a car.
Yes, a ground-level slab should be tested first, because one maker warns that moisture vapor coming up through it can make a coating blister and lift away. That maker calls for a calcium chloride test, which measures how much moisture the slab gives off, and a vapor control system before coating when levels run high. If yours needs that step, it'll be in your estimate.
Clear everything off the floor, including shelves and anything stored along the walls, so we can reach every part of the slab and its edges. If you know roughly when the slab was poured, or whether it's been painted or sealed before, please tell me, since new concrete and old coatings both change the prep.
Dust mop it, clear away grit and debris, and clean it regularly, which one maker says keeps the coating looking good and helps it reach its full life span. Please don't spin your tires on it, because that heat quickly softens the coating and can permanently damage the finish.
We're open seven days a week, Monday to Friday 8 AM to 9 PM and weekends from 6 AM to 9 PM, so call (510) 931-7868 when it suits you or send the form.
