Want a hard floor that lasts decades but unsure your slab can take it? We match the terrazzo system to what's underneath.
Terrazzo flooring in Castro Valley is a custom floor we pour in place over your base, let cure, then grind down to a smooth, hard finish. When it's put in well and looked after, it can last for decades.
Most people who call about terrazzo want a floor they can keep for the life of the house. Terrazzo is made mostly from natural products, so you'll see slight shade changes from one part of the floor to another, and that's normal. The bigger question is what's underneath, because the base decides which system will hold.
The price moves with the system you pick, the size of the room, how detailed the design is and how much prep your slab needs before we pour. The schedule turns mostly on the system, because some cure much faster than others, and on the shape your base is in. I'll put both in writing after I've seen the floor.
Before you pick colors, a few things about the floor itself shape how a terrazzo job goes. These are the ones I talk through at nearly every estimate.
Cracks, high spots, old coatings and signs of moisture all change what the floor can carry. I'd rather tell you a slab needs more work, or a different system, than pour over a problem and hope it stays hidden. The questions further down explain how epoxy and cement terrazzo differ on this.
Divider strips are thin strips set into the floor that keep one color from running into the next and give the floor its lines. A plain field with a border goes quicker than a detailed pattern with many colors, because every strip has to be set straight and level before the pour.
Between the pour, the cure and the grinding, the room can't be walked on or furnished for a stretch. Grinding also makes a wet slurry, so we cover doorways and nearby floors, keep the mess inside the work area and clean up as we go, because it's your home and not ours.
Here's how a terrazzo job goes with us, from the first call to the last walk across the finished floor. You'll know who's coming and what you'll get at each step.
Call (510) 931-7868 or send the form with a little about the room. We'll get back to you to set up a time for me to come out and see the floor.
I come out myself, look over the slab for cracks, moisture and old coatings, and ask how you'll use the room. Then you get a written estimate with the price, the system and the prep spelled out.
Once you're ready, our crew preps the base first, because that's what decides whether the floor holds. Then we put down the system we agreed on, let it cure and grind it to a smooth finish.
Before we leave, I walk the finished floor with you, point out anything worth knowing and go over how to look after it. If something isn't right, please tell me then, while we're both standing on it.
Terrazzo starts with choosing the right system for the floor underneath, so that's where I start too. I look at your base, talk through the epoxy and cement options with you, and bring real samples so the natural shade changes across the floor come as no surprise. A photo on a phone won't show you that, but a sample in your own light will.
Most of the work is the part you'll never see. Before anything is poured, the base has to be clean, sound and flat enough for the system, and that usually means concrete grinding and surface preparation comes first. If the room is below ground, we'll also talk about whether terrazzo fits or one of our basement flooring options suits the space better, because a basement asks different things of a floor.
Poured terrazzo gives you one continuous floor with your own pattern. Terrazzo tile costs less per square foot, so it's worth weighing if the budget is tight and a seamless look matters less to you.
Marble is the classic look. With epoxy terrazzo you can also use glass, synthetic or granite chips, which give brilliant colors or stand up better to chemicals. I'll bring samples of each so you can compare them.
Send the form and we'll reply within one business day to set up a visit. The estimate is free, done on site and comes with no obligation, so I'll look at your slab, ask how you use the room and put the price and the prep in writing for you to think over. Thank you for considering us.
(510) 931-7868Castro Valley isn't its own city, so Alameda County issues building permits here, and owners apply through the county's online permit portal. Whether your terrazzo floor needs a permit is something I'll look at for your job rather than guess. If it does, I'll say so at the estimate and take care of filing it with the county, or walk you through it if you'd rather file it yourself.
We're based in Castro Valley and work in Hayward, San Leandro, Oakland, Dublin, Pleasanton and many other cities around it. Around here we see plenty of garage and basement slabs that have been painted, patched or covered more than once, so old coatings and repairs often have to come off before a new floor goes down. We bring the same careful prep to homes in Hayward and San Leandro.
When you call, I'm the one who comes out to look at your floor, and I stay on the job with our crew from the first pass of prep to the final walk-through. We've been doing this since 2017, and I learned it on real slabs, one at a time, which is why I'll tell you plainly if yours needs more work before anything goes down.
We're licensed and insured. We stand behind one promise, satisfaction guaranteed on every job. We also treat your home as someone else's property, because it is, and leave it clean when we go. To get started, please call (510) 931-7868 or send us the form and tell me a little about the room.
If your slab has old coatings, glue or high spots, grinding it clean and flat is the step that lets a new terrazzo floor bond and sit level.
Below-grade rooms bring their own conditions, so if you're weighing terrazzo for a basement, it helps to see every flooring option suited to that space.
We're based in Castro Valley and do terrazzo and concrete floor work across the cities around it. Find your city below, and if you don't see it, please call and ask.
Installed terrazzo flooring across the US usually costs about $20 to $50 per square foot, and that's the market's range, not our quote. Where your floor lands depends on the system, the design and how much prep your slab needs. I'll come out, look at it and give you a written price for your room.
With proper installation and upkeep, a terrazzo floor usually lasts 40 to 100 years or more, and some outlast the building. The upkeep is simple, mostly weekly sweeping or damp mopping plus resealing every so often, so a long life depends as much on that care as on the install.
Epoxy terrazzo suits a very flat indoor slab, while sand cushion cement terrazzo suits a base with flaws, because it breathes and tolerates them. Epoxy is a thin resin layer that doesn't breathe, so a moisture barrier may be required. Sand cushion needs a lowered area in the floor, offers few vibrant colors and takes a long cure.
Terrazzo installation takes anywhere from 3 days to several weeks, depending on the type, size, design, prep work and base. Cement terrazzo takes longer to cure than epoxy, which has the quickest time from pour to grind, so if your schedule is tight, epoxy is usually the better fit. I'll lay out a realistic plan at the estimate.
Epoxy terrazzo can go over plywood, as long as the plywood is properly installed and prepared for it. If your floor is framed with plywood rather than a concrete slab, please mention it when you call, and I'll look at what the plywood needs before we talk about a pour.

Call (510) 931-7868 or send the form with the room's square footage, what the base floor is and photos of any old terrazzo, so I can bring the right samples to the visit.
