What goes into a new concrete floor in Kirkland?
Concrete floor installation in Kirkland means placing a new concrete slab, usually right on the ground, then finishing it, cutting its joints and curing it so it becomes the hard surface you walk on or lay flooring over.
Most people who call about a floor have a basement, a shop, an addition or an outbuilding that needs a slab, or an old one that's cracked and dusty enough that patching isn't worth it anymore. The price moves with the size, how much digging and base work the ground needs, whether the slab needs steel in it, what's going on top and how close we can get the truck. The schedule depends on the weather, any permit the job needs and how long the slab cures before anyone loads it up. The written estimate I send after seeing the site gives you the figure for your floor. If it's a garage you're after, our garage floor concrete page covers that job on its own.
How do you know your concrete floor needs replacing?
Cracks across the floor
Cracks that wander across the slab instead of following a straight groove usually mean the joints were cut late or never cut, or the ground underneath moved. They tend to widen and pull apart over time, and any flooring laid over them will usually crack in the same spot.
Gray dust on everything
A floor that keeps shedding fine powder usually has a weak top layer, often from finishing too soon or letting it dry out too fast after the pour. Sweeping won't fix it, because the surface keeps wearing down underneath you, and it only gets rougher.
Flooring lifting or smelling musty
Vinyl that bubbles, wood that cups or carpet that smells damp usually points to moisture coming up through the slab. Put new flooring down over the same slab and it tends to fail the same way, so the slab is the part to fix.
How we handle concrete floor installation
The first thing I ask is what's going on top, because a floor getting vinyl, wood or carpet needs a different setup under the slab than one that stays bare, and that has to be decided before the pour. Then we dig out and pack the subgrade, the dirt and gravel the slab sits on, instead of raking it level and hoping, because a soft base settles and takes the floor down with it. We check where the water runs, set the forms and add rebar, steel bars that hold the slab together if it does crack, when the job needs it. We pour early in the day instead of in the midday heat, finish the surface and cut control joints, shallow grooves that give the slab a planned place to crack, before it gets the chance to pick its own spots. After that we cure it, keeping it from drying out too fast so the top comes out hard instead of dusty, and we plan the finishing and curing so none of it gets rushed. If the budget's tight, don't take it out of the base. Nobody sees the base the day we pour, but it decides whether the floor stays flat, and a plain finish over good prep beats a fancy one over loose dirt.
Floors often come with other work around them. If the new slab meets an outside door, we can pour concrete steps to match its height while we're set up, and if there's a pool out back, our concrete pool decks get the same base work with a surface made for wet feet.
A slab that gets flooring
This suits basements, additions and finished rooms getting vinyl, wood, carpet, laminate or an epoxy coating. We set up what goes under the slab for that covering and finish the top smooth so the flooring lies flat.
A bare concrete floor
This suits shops, storage rooms and utility spaces where the concrete is the floor you live with. We can trowel it smooth for easy sweeping or give it a broom finish, a light brushed texture that adds grip where things get wet.

Why Kirkland homeowners call Precision Kirkland Concrete for floors
The owner writes your estimate
I come out to look at the job and write the estimate myself, and I'm on site with our crew when we pour. You deal with the person who answers for the floor, not someone passing along notes.
Six years of flatwork
We've been in business since 2020, and most of what we pour is flatwork, the flat slabs like driveways, patios, walks and garage floors. A floor is the same kind of job, so the prep habits carry right over.
Licensed and insured in Washington
We're licensed and insured. Washington requires every construction contractor to register with the state, and checking any contractor takes about a minute online, as the questions below explain.
If you know how big the floor is and what's going on it, send us the details or call (425) 285-8195 and I'll come take a look.
Concrete floors and site prep in Kirkland
The City of Kirkland requires a permit to build, alter or repair a building, and its list of work that doesn't need a permit names driveways and sidewalks but not floor slabs, so that list doesn't settle whether your floor needs one. The prep can bring its own rules too, because the city treats digging out or bringing in more than 50 cubic yards of soil, or any work that changes where water drains, as permit work. Steep slope, wetland, flood hazard and shoreline areas don't get the city's usual exemptions, and the city has special zoning rules for property with landslide-prone ground. The city's Property Search Tool makes a Parcel Report showing whether any of that applies to your address, and I check the same thing before we start. When a permit is needed, we can file it for you or help you file it.
Plenty of floors we pour sit on sloped lots or behind houses with tight access, so we look at where the water goes and how the truck gets in before we price anything. We take the same approach across King County and south Snohomish County, including jobs in Bellevue and Redmond, and if your city isn't listed, call and ask.
Questions about concrete floors in Kirkland
How much does a concrete floor cost in the Seattle area?
A concrete slab in the Seattle area usually costs about $7 to $14 per square foot, according to one local cost guide. The same guide puts reinforced slabs a little above plain, unreinforced pads, and staining or stamping costs extra on top of that range. Your written estimate gives you the price for your own floor.
When can I walk on a new concrete floor in Kirkland?
A Seattle-area cost guide says a new slab should be walkable within 48 hours. It suggests waiting about a week before heavier loads, so plan on light foot traffic first and hold the heavy furniture, shelving or equipment back for that week.
How long does a concrete floor take to fully cure?
Concrete takes about a month, 28 to 30 days, to fully cure, by that same Seattle-area guide. The slab keeps getting stronger the whole time, even after you've started walking on it. If flooring is going down, we'll talk through the timing for it at the estimate.
Can concrete floors be poured in cold weather?
Yes, as long as the fresh concrete is protected from freezing. National guidance says concrete freezes if its temperature drops below about 25°F, which can cut its potential strength by more than half, and it calls for protection until about two days after the pour. On a winter job we plan that protection before we set the pour date.
What is the best way to keep moisture from ruining flooring over a concrete slab?
National guidance says floor coverings get the most protection when the vapor retarder, a plastic barrier under the slab, sits in direct contact with the concrete. That keeps water from rain, curing or cleaning from getting trapped in the fill layer underneath. Sheet vinyl, vinyl tile, carpet, laminate, hardwood and epoxy coatings all count as moisture-sensitive, so it's worth settling the covering early.
How do I check a concrete contractor's registration in Washington?
Use the Verify a Contractor tool from Washington L&I, which shows whether a business has an active contractor registration and a paid-up workers' comp account. It also lists safety violations and any lawsuits against the contractor's surety bond. Look us up the same way before you sign anything.
