Concrete floor installation in Kent WA - a slab ready for the flooring you choose
Your old floor is cracked, uneven or chipping, or you need a slab for new space. We pour one that's level, jointed and cured right.
What goes into a new concrete floor in Kent?
Concrete floor installation in Kent, WA is the work of preparing the ground, pouring a new slab and then finishing, jointing and curing it, so the floor wears well and drains the way it was planned. Most of your wait comes after the pour, while the slab cures.
Maybe the old floor is cracked, sinking or chipping, or you're closing in a shop or an addition and need a slab to build on, and if it's a garage, our garage floor concrete page covers that job. The price moves mostly with the size in square feet, how thick the slab has to be, whether it needs steel, what goes underneath for your flooring and how much old concrete or dirt has to come out first. The schedule turns on the permit, the weather on pour day and the curing wait afterward, so I'll walk your site and give you a written estimate with each part listed, and that's where you see your own number.
How we handle concrete floor installation, step by step
It starts with one question. Tell us what flooring you plan to put on top, because it decides what goes under the slab before we pour, and national concrete guidance says the vapor retarder, the layer that slows ground moisture rising through the slab, should suit that flooring or coating, with ordinary polyethylene sheeting no longer considered right for it. Then we dig out and pack the subgrade, the ground the slab rests on, so it doesn't settle the way loose dirt does, set the forms to our measurements and check where water will run. Rebar, the steel inside the slab, goes in where the floor needs it to hold cracks tight, and then we pour. We time the finishing and the joints to how the slab is setting up, not to whatever is handy that day, because bad timing is what leaves a dusty top, high and low spots and cracks in places nobody picked. Control joints are grooves we cut so the slab cracks along a line we chose, and then it cures, the slow wait while the concrete gains strength before it takes weight. If the budget gets tight, I'll point you to a plainer finish before I'll skimp on the base, because nobody sees the base on day one but it decides whether the floor stays flat.
A new floor often meets other concrete. Where it sits higher or lower than a door or the yard, we can pour concrete steps so the change in height is easy to walk, and if the slab opens onto a pool area, our concrete pool decks work ties in with it.

Questions before you book a concrete floor
How much does a concrete floor cost near Kent, WA?
A concrete slab or pad in the Seattle area usually costs about $7 to $14 per square foot, and that's the going range in the market, not a quote. Reinforced slabs run higher per square foot than plain pads, and those usual figures leave out staining or stamping. Your written estimate lists each part of your own floor so you can see where the money goes.
Is it normal for a new concrete floor to crack?
Yes, a few cracks are normal, and national concrete guidance says a floor with no cracking or curling at all isn't realistic, even when it's designed and built right. Joints and enough steel keep the big visible cracks in check, but small cracks from the concrete drying and shrinking still show up in most slabs. I'd rather tell you that now than promise something concrete can't do.
How long does a new concrete floor take before I can walk on it?
Seattle-area figures say a slab should be walkable within 48 hours. Waiting a week before heavier loads may be safer, and full curing takes a month, so plan moving in heavy things around those times.
Do I need a permit to pour a concrete floor in Kent?
Check before you pour, because the City of Kent Permit Center issues building permits and permits for residential work, and you get them by making an appointment. We check which city or county office covers your address, take care of the permit when your job needs one and keep you posted on where it stands.
Can a concrete floor be poured in cold weather?
Yes, and national guidance counts any pour where the air is at or expected to drop below 40°F while the concrete is being protected as a cold weather pour. Concrete placed then still gains its strength and durability when it's mixed, placed and protected properly, with more protection as it gets colder. If your date lands in a cold stretch, ask us how we'll protect it.
What causes a dusty surface on a new concrete floor?
Finishing at the wrong time is a common cause, and so are fumes from fuel-burning heaters and engines, because carbon monoxide can leave dust on concrete that's less than a day old. If the space needs heat or equipment running that first day, ask us how it'll be handled before the pour.
Work that often goes with a new floor
- Concrete pool decks
If your new floor opens onto a pool area, a deck poured with the right slope and texture keeps water moving away and gives bare feet steady footing around the edge.
- Concrete steps construction
When the new slab sits higher or lower than the door, yard or porch beside it, solid concrete steps make that change in height comfortable to walk every day.
