What goes into a new concrete floor in Redmond?
Concrete floor installation in Redmond means pouring a new slab over a dug-out, packed base, with the joints and what goes underneath planned for the flooring you'll lay on top, so the floor stays flat and your tile or wood stays down.
Most calls start with a basement, shop or addition where the old slab is cracked and uneven, or where there's no real floor yet. The price moves with the size of the room, how much soft ground has to come out, whether the slab needs steel, what goes under it for your flooring and how easily we can get concrete into the space. The schedule turns on whether a permit is needed, the weather on pour day and curing, the days fresh concrete needs before it can take weight. If an old slab is in the way, we start with concrete cutting to get it out, and your written quote spells out what your job comes to.
How do you know your concrete floor needs replacing?
Cracks that keep growing
If cracks in the old slab are widening or one side now sits higher than the other, the ground under it has usually settled. Waiting lets it keep moving, and any tile or flooring you lay over it will crack along the same lines.
Flooring that lifts or stains
Tile popping loose, wood cupping or carpet that smells damp over a slab usually means moisture is coming up through the concrete with nothing to stop it. Putting new flooring down on the same slab just means paying for that flooring twice.
A dusty, soft surface
A floor that sheds powder every time you sweep it was often poured in the heat or finished too early, and the top never got strong. It keeps wearing, and paint, sealers and adhesives have a hard time holding on to it.
How we install a concrete floor
I start by asking what's going on top, because tile, wood and carpet each change what goes under the slab. Then our crew digs out to firm subgrade, the ground the slab sits on, and packs a solid base, since a base that's only raked level settles and takes the floor with it. Where the floor needs it we set rebar, steel bars that hold the slab together and keep cracks tight, then we pour early enough to dodge the afternoon heat, because concrete that sets too fast ends up with a weak, dusty top. Before the pour I lay out the control joints with you, the shallow cuts that give the slab a straight place to crack, so you know where they'll land, and we cut them on time instead of letting the slab pick its own lines. If the budget gets tight, trim the finish and keep the base, because the base is buried on day one and nobody can fix it once the truck has left.
A new floor often changes what happens at the doors. If it leaves a step down to the yard or the garage, we can pour concrete steps while we're set up, and if the room opens onto a pool, we build concrete pool decks too.

Concrete floors, steps and pool decks in Redmond
In Redmond, the city requires a building permit for any project that isn't on its no-permit list, and that list names sidewalks and driveways, not concrete floors, so the list alone doesn't settle whether your floor needs one. If your job needs a permit, we tell you at the estimate and handle the application and the inspection requests, which the city wants throughout the job and before anything gets covered, because a skipped inspection can hold the project up. The city's residential code also rates Redmond for moderate weathering damage and sets its own seismic and frost line rules, which is why we build to local code instead of a plan from somewhere else. And if a contractor's work ever costs you money, eligible homeowners can apply to the state's recovery program for payments.
Around here the calls are mostly basements, shops and additions, often with an old slab that cracked or sank because the base was never packed. We see the same jobs in Kirkland and Bellevue, and we plan pour days around the wet months so rain doesn't spoil a fresh surface.
Questions about concrete floors in Redmond
(425) 285-8289How much does a concrete floor cost in Redmond?
A concrete slab in the Seattle area usually costs about $7 to $14 per square foot, before any staining or stamping. A reinforced slab costs more per square foot than one without steel, and decorative finishes get budgeted separately. I'll price yours at the estimate.
Will my new concrete floor crack?
Probably a little, because industry guidance says even a well-designed, well-built floor isn't realistically crack-free. Properly designed joints control and minimize cracking, so what you should expect is a few small, controlled cracks. Ask how the joints will be laid out before anyone pours.
Does tile or wood flooring need moisture protection under the concrete slab?
Yes, industry guidance calls for protection from moisture moving up through the slab under carpet, tile, wood, vinyl and poured coatings. Without it, water vapor can break down the adhesive, so flooring lifts, warps or stains, and you can end up with trip spots and possibly mold and odors. The same guidance finds a vapor barrier laid right against the bottom of the slab protects floor coverings best, though extra water rising to the surface can slow finishing and make the pour day run longer.
How long before I can walk on a new concrete floor?
You should be able to walk on a new slab within 48 hours. To be safe, wait about a week before putting heavier loads on it, like furniture or equipment.
How long does concrete take to fully cure?
Concrete typically takes about a month, 28 to 30 days, to fully cure. The floor keeps gaining strength for weeks after you can walk on it, which is why heavy loads wait.
What is the best way to prepare the ground for a concrete floor?
Remove all the topsoil and soft spots, then compact the base by rolling, vibrating or tamping before any concrete goes down. The slab sits on that packed soil or crushed rock, and a base left soft settles and takes the floor with it.
Concrete work that often goes with a new floor
Concrete pool decks
If your new floor opens onto a pool, a matching deck outside keeps the levels and drainage planned together instead of patched in later.
Concrete steps construction
A new floor can change the height at a doorway, and poured steps give you a solid, even climb in or out of the room.
