Concrete floor installation in Federal Way WA - a flat slab built on a solid base
Old floor cracked, sinking or uneven? We dig out, pack the base and pour a new concrete slab that's finished flat and jointed where cracks belong.
What does it take to put in a new concrete floor in Federal Way?
Concrete floor installation in Federal Way means we prepare the ground, pour a new slab, then finish, joint and cure the surface so it's ready to use bare or to carry flooring, adhesives or coatings.
Most calls start with an old floor that's cracked, sunk or gone uneven, or with a new room, shop or addition that needs a slab before anything else can go in. Either way, the work under the surface decides how the floor holds up, so that's where I start.
The price moves with the floor's size and thickness, how much digging and base work the ground needs, whether a vapor barrier and reinforcing steel go in, and how easy it is to get a truck and crew to the spot. The schedule turns on any permit wait, a good pour day and when your flooring needs to go down, and your estimate gives you the figure for your floor.
- We dig out soft dirt and pack the subgrade, the ground the slab sits on.
- We cut control joints, shallow grooves that give the slab a planned place to crack.
- Curing comes last, keeping the fresh slab damp and covered so the surface hardens strong, not dusty.
What happens when you call us about a concrete floor?
I'm the one who comes out to look at your floor and the one running the crew on pour day. Here's how the job runs and what you'll have in hand before you decide anything.
Call or send us a message
Call (253) 652-2604 or use the form, and tell us the floor's size in square feet and any flooring you plan to put on it. We'll set a time for me to come out.
I look at the site
I walk the space with you, check the ground and access, and ask what the floor needs to carry. Then I write an estimate that lists what's in the price and what isn't, so you can hold it up against any other bid line by line.
We sort out permits and dates
Once you say go, we check which city or county office covers your address and handle the application if the job needs a permit. Then we pick a pour day with you that fits around that wait.
We pour, finish and clean up
I'm on site running our crew while we form, pour and finish, and we keep your yard and the street tidy as we go. The work is backed by our satisfaction guarantee.

(253) 652-2604Common questions about new concrete floors
These are the questions I hear most from people planning a new concrete floor. The short answer comes first, then what to ask any crew you're comparing.
Will my new concrete floor crack?
Probably a little, because today's methods reduce cracking and curling, where the edges lift slightly at the joints, but no one can build a floor that does neither. What you can judge is how a crew plans to keep both down, so ask every bidder about their base, joints and finishing before you pick one.
How much does a concrete floor cost in the Seattle area?
A new concrete slab in the Seattle area usually costs about $4 to $9 per square foot, and that's the going range for the slab, not our price. Your own number comes from the estimate, which lists what's in the price and what isn't.
When can I put flooring down on a new concrete slab?
Give it time, because a new slab loses moisture unevenly and curls slightly at the joints, and that can complicate laying some floor coverings in the months after the pour. We talk through your flooring before we pour so the schedule leaves room for it.
What is the best way to keep moisture out of a concrete floor?
Put the vapor barrier right under the slab, touching it, since industry guidance says that's where it best protects floor coverings, coatings and the building. The same guidance says plain polyethylene shouldn't be counted on for that job, so ask each bidder where their barrier goes and what it's made of.
What causes high spots and cracks in a new concrete floor?
Bad timing is a big one, because finishing, cutting joints and curing each have a window, and missing it can lead to cracks, high or low spots and water that won't drain. Ask any crew who's on site when the finishing and joint cutting happen.
How do I check a concrete contractor's license in Washington?
Look the business up with the state's L&I Verify tool, which shows whether its contractor registration is active and whether it has a paid-up workers' comp account for employees. Washington requires every construction contractor to register with Labor & Industries and carry a bond and insurance, and the tool also lists safety violations and lawsuits against a contractor's bond. We're fully licensed and insured.
Concrete floor installation in Federal Way and nearby cities
Federal Way requires a permit for nearly every improvement on a home lot, its exemption list doesn't name concrete floors, and work in wetlands, streams, landslide areas or their buffers isn't exempt, so I check with the city's building division and handle any application. We're based here and pour floors in the cities around it, from Kent to Tacoma.
