What goes into a new concrete garage floor in Lewiston?
Garage floor concrete is a new slab poured for your garage on a dug-out, packed base, with the mix and the pour date picked for cold winters and salty tires. In Lewiston, ID, a lot of the floors I look at are old ones that have cracked, sunk or started flaking after years of freezing and road salt.
Maybe you're parking on a floor that's cracked across the middle, dropped at one corner or holds water by the door, or you're building a new garage and want the floor done right the first time. Price mostly follows the size of the garage, whether an old slab has to come out and how much digging and base the ground needs. The schedule turns on the permit check and the weather, because concrete guidance urges caution about pouring in late fall, winter or early spring if the fresh slab could freeze while it's still full of water, so if you're aiming for the cold months, ask how we'll keep it from freezing. Your written estimate lays out the prep, the mix and the joint layout for your garage.
Why Lewiston homeowners call Lewiston Concrete for garage floors
The estimate comes from me
I come out to look at your garage and write the estimate myself, and I've run this business since 2017. The person you talk to is the one there on pour day.
Licensed and insured for your job
Idaho requires anyone taking on a construction job over $2,000 in materials and labor to register as a contractor, unless exempt. We're licensed and insured, and it's fair to ask anyone bidding your floor.
Working both sides of the line
We're based in Lewiston and pour floors in Clarkston, Moscow, Pullman and the areas around them, so the same crew handles your floor on either side. If you're not sure we come your way, just ask.
On a garage floor, the base and the joints decide how it holds up, and both get settled before the pour. Send us a message and I'll come out and look at yours.
What our garage floor concrete work includes
If the old floor is cracked through or sinking, I'll tell you it needs to come out rather than sell you a topping that won't hold, and we break it out and haul it off. Then we dig out the soft dirt and pack the subgrade, the ground the slab sits on, because a floor raked level over loose fill settles right along with it. Before we form, we check the fall so water runs out the door instead of toward the house wall, and we set rebar, steel bars that hold cracks tight, where the slab calls for it. We pour in the cooler part of the day, since a slab poured in midday heat can end up with a weak, dusty top. After finishing, we cut control joints, shallow cuts that give the slab a place to crack, so the floor cracks along lines I picked instead of wherever it wants, and then it cures, the wait while the concrete gains strength before it takes weight.
A new garage floor often leads to the work around it. If you'd like the apron or the walk to the side door to look like more than plain gray, decorative concrete adds color or pattern. Where the garage sits into a slope, concrete retaining walls keep the soil and runoff from pushing onto the slab.
Smooth troweled floor
A steel-troweled finish is easy to sweep and roll a creeper across, which suits a workshop or a daily parking spot. It can get slick when snow melts off the tires, so keep that in mind if the car comes in wet.
Broom finish
A broom finish, a light brushed texture, gives your feet grip on wet concrete, so it suits the apron outside the door. Some people use it inside too when the floor stays wet most of the winter.
How do you know your garage floor needs replacing?
Cracks that keep growing
A crack that widens or sprouts new ones usually means the dirt underneath has moved. Waiting lets water and salt get in, and the slab breaks into more pieces to pull out.
A corner sinking or tipping
A slab that drops at a crack or tilts toward one corner usually sits on fill that was never packed. It keeps settling, and the trip edge and puddles only get worse.
Water pooling or running inward
Puddles that sit on the floor or run toward the back wall mean the slab falls the wrong way. Every winter that water soaks the base and works under walls and doors.
The top flaking off
A surface peeling away where the car parks usually comes from freezing, thawing and salt working together. Once it starts it spreads, and a patch over weak concrete usually lets go.
What happens after you call about a garage floor?
Call, then I come look
I come out, look at the garage and talk it through with you. Then I send a written estimate spelling out the prep, the mix and the joint layout.
Settle permits, then pour
We ask the city or county office covering your address whether you need a permit, handle it if so and pick a pour date around the weather. I'm on site running the crew when we form, pour and finish.
Finish, cure and hand over
I stay with the job through finishing and curing. Before we leave, I'll tell you when you can walk on the floor and when you can park on it.
Garage floor questions we hear
These are questions people in Lewiston often ask before a garage floor goes in. If yours isn't here, call (208) 848-5044 and ask about your own garage.
Does my garage floor in Lewiston need air-entrained concrete?
For a floor that freezes and thaws and sees road salt, industry guidance says yes, order good quality air-entrained concrete. The mix carries tiny air bubbles that give expanding water and ice somewhere to go, and that matters in a garage because the salt dripping off your car adds freeze and thaw cycles right at the surface. I'll go over the mix with you before anything gets ordered.
Will my new concrete garage floor crack?
Some, probably, and I'd rather tell you that now. Slab design guidance says crack-free and curl-free floors aren't realistic even with the best design and proper building, so expect some cracking and some curling, where slab edges lift slightly, on any floor. The control joints we cut are how we steer most of that cracking onto lines we chose.
Can I coat my new garage floor later?
You can, but tell us before the pour, because that's when we can plan for it. Moisture rising up through a slab can make a coating fail, peel away or discolor, and industry guidance calls for protection from that moisture when a floor will get tile, wood or seamless flooring. That protection goes in under the slab, so it can't be added once the concrete is down.
Who decides if I need a permit for a garage floor in Lewiston?
The City of Lewiston decides. Its permit representatives take requests through the city's Permit Portal and talk through your project to work out whether it needs a permit or a plan review. You can reach them at cd@cityoflewiston.org or 208-746-1318, option 1, or start on the city's Building Services page.
How much does a new concrete garage floor cost in Lewiston?
It depends on the size of the garage and what's under it, so I price each one after seeing it. Tearing out an old slab, how much soft dirt has to be replaced with packed base, how easily the truck can reach the garage and the finish you pick all move the number. The base is the part nobody sees once it's poured, which is why it's the first thing people want to cut, and it's the last place I'd save money because a floor is only as solid as what it sits on.
How do I keep road salt from damaging my new garage floor?
Go easy on deicing salt and hose off what your car tracks in when the weather allows, because heavy use of deicers raises the chance of scaling, where the top layer flakes off. On a newly poured floor, skip deicers through the first winter if you can and use clean sand for grip.

When the garage or driveway is cut into a hillside, a poured wall keeps the bank from slumping onto the slab and sends runoff where it belongs.
