Dirt floor, loose gravel or a cracked old slab in the room? We pour a level concrete floor ready for tile, wood or a coating.
Concrete floor installation in South Lake Tahoe means we dig out and pack the base, lay a vapor barrier, then form, pour and finish a flat slab that can take tile, wood, carpet or a coating.
Most of the floors I look at start as dirt, gravel or an old slab that's cracked and sunk, in an addition, a converted garage or a room someone finally wants to finish. Most of the job is the part you won't see later, the ground under the slab and the sheet that keeps moisture out of it. Get those right and whatever goes on top has a fair chance.
The price moves with the size of the room, how much digging and base work it needs, whether the slab gets steel in it, and how hard it is to get concrete to the room. The schedule turns on the permit side, the weather on pour day and the curing time before your flooring goes down. The written estimate shows what's included and what isn't, so you can compare it fairly.
These are the parts of the job I watch closest, because they're what a rushed crew skips and they're the hardest to fix once the slab is in.
The subgrade, the ground the slab sits on, has to be dug out and packed hard, not just raked level. Loose dirt settles over time and the slab goes down with it, so we compact the base in layers and check that it's flat before anything else goes in.
Concrete shrinks as it dries, and it's going to crack somewhere. Control joints are shallow cuts we put in on purpose so the cracks follow lines we picked. Cut them late or skip them and the cracks wander across the room wherever they like, often right under a tile line.
Timing matters even indoors. A slab that dries too fast, or gets worked before it's ready, can end up with a weak, dusty top that keeps shedding powder. We set the pour for the right part of the day and finish when the concrete is ready, not when the clock says so.
Here's how a floor job runs from the first call to the day you walk it with me. You talk to me at the start, and I'm there on pour day.
I answer the phone myself. Tell me where the floor goes, roughly how big the room is and what you want on top of it, and we'll set a time for me to come look.
I come out, ask what the floor has to carry and check what's around it, like doorways, walls and how we'll get concrete in. You get a written estimate showing what's included and what isn't.
Once you say go, we sort out the permit side and get buried lines marked before anyone digs. We pick a pour date the weather allows, then build the base, lay the barrier, form, pour and finish.
When it's done, we walk the floor together and I leave you plain care instructions, including when it's fine to walk on and when the heavy furniture or flooring can come in.
I'm fussy about the vapor barrier, the plastic sheet between the base and the slab, because a torn sheet under the floor turns into a flooring problem later. Moisture comes up through the hole, and the glue, tile or coating on top is what pays for it. Nobody sees that sheet again once we pour, so it gets our full attention before we do.
We pick rocks and anything sharp out of the base first so nothing pokes through. The sheet goes right under where the concrete will sit, seams get taped, and any nick gets patched before the truck shows up. An indoor floor gets troweled smooth, unlike outdoor slabs such as concrete pool decks, which get a broom finish, a light scratched texture for grip underfoot.
When a budget gets tight, the base is the first thing people want to trim, because on day one nobody can see it. I'd rather trim the finish. A plain floor on a good base stays flat, while a fancy surface on a soft base settles with the dirt, and then you're paying twice.
If the new floor ends up higher than the ground outside a door, plan any concrete steps at the same time so the heights match and we're not breaking into fresh work later. And if pour day looks wrong, I'll tell you to wait for a better week rather than pour into it.
If tile, wood or carpet goes on top, we finish the slab smooth and flat for the flooring crew. If the bare concrete is the finished floor, it needs more care in the finishing and usually a coating, so tell me early.
Rebar is steel bar set inside the slab so it holds together under load. A floor carrying a workshop or heavy shelving usually wants it, a light-use room may not, and I'll tell you which yours is at the estimate.
Send the room size, the flooring you plan to put down and when you'd like to start, and I'll get back to you within one business day. I come out, look at the room and give you a free written estimate. There's no obligation, and you decide from there.
(530) 307-5972Building and planning permits in the city go through the City of South Lake Tahoe Building Division, and every application, inspection request and payment has to go through its online system, eTRAKiT. Whether your floor needs a permit depends on the job, and I won't guess at it. If it does, we work out which office it goes to and help you file before work starts, and when something's unclear, we ask the city.
The state license board counts forming, pouring, placing and finishing flat concrete as concrete contractor work. California only lets someone work without a license on a job up to $1,000, and only when the job needs no permit and they have nobody working for them, so check the license of whoever pours your floor.
We're based in South Lake Tahoe and work in the cities around it too. Most indoor floor calls here are additions, converted garages and older cabins with a dirt or worn-out floor, and the questions tend to be the same ones about moisture, the height at the doorways and how soon the flooring can go in.
I came to concrete later than most, after years in other work, and learned it on a finishing crew before starting South Lake Tahoe Concrete in 2021. Five years in, I still answer the phone, come out to look at the job and write the estimate myself, and people know us for doing the dull prep properly and giving straight answers on cost and timing.
The work is done by a small crew of experienced form setters and finishers, and I'm on site for the pour. We're licensed and insured. Our work is backed by our satisfaction guarantee.
If you're planning a floor, call me at (530) 307-5972 or use our estimate form, and we'll set a time to look at the room.
If you're redoing the outside too, a pool deck needs a textured surface and planned drainage, which makes it a very different job from a smooth indoor floor.
When a new floor changes the height at a doorway, new steps outside keep each rise even so nobody catches a toe going in or out.
We're based in South Lake Tahoe and take floor jobs in the cities around it too. If you're nearby and not sure we come out your way, call and ask.
A price guide for Sacramento puts a concrete slab or pad at about $7 to $14 per square foot, and the same guide has reinforced slabs costing slightly more per square foot. That's a Sacramento market figure, not our price. Your written estimate gives the real number for your room, your base work and your access.
Usually within 48 hours, according to that same Sacramento guide, which also suggests waiting about a week before heavier loads and says full cure, the slow hardening concrete keeps doing, takes 28 to 30 days. Air and ground temperature, humidity, wind, slab thickness and the mix all change how fast that goes.
Yes, with a plan for the first two days. National guidance says fresh concrete freezes if its temperature drops below about 25°F, which can cut its potential strength by more than half, so it should be protected until about two days after placement. Snow and ice come off first, and the ground it touches should be above freezing, which can mean insulating or heating it beforehand.
For a floor that will get tile, wood, carpet or a coating, yes. National guidance says those coverings get the most protection when the barrier sits directly under the slab, and even small holes in it can let more moisture through, which can lead to failed flooring and delays in putting it down.
Expect some small random cracks, because national guidance says a floor slab can crack even with closely spaced joints. Steel reinforcement won't prevent cracking, but sized and placed properly it keeps cracks tight. The control joints we cut steer the cracking into straight lines we picked instead of across the room.
Either the property owner or a California licensed contractor can get a permit from the city's Building Division, according to a city handout. Either way, the application runs through the city's online system, and if your floor needs a permit, we'll help with the filing before work starts.
Clear the room and a path to it, because base material, forms and concrete all come in that way. Move anything you care about away from the doorway, keep pets and kids clear on pour day, and have your flooring choice settled so we finish the surface to suit it.
Your flooring date hangs on when the slab is poured and cured, so call (530) 307-5972 or use the form and we'll plan the pour around it.
