What does a new garage floor take in Northport?
Garage floor concrete is a slab poured on packed ground and built to carry the weight of your vehicles. Here in Northport, AL, we replace worn garage floors and pour new ones so you end up with a floor that settles evenly and keeps cracking in check.
Most calls start with a floor that's cracked through, sunk at one corner or flaking under the tires, or with a garage that never got a proper floor. The price moves with the size of the garage, how thick the slab has to be for what you park, and whether an old floor has to be broken out and hauled off first. The schedule moves with the permit, the weather on pour day and how much digging the ground needs before we can pack it. If the floor meets a tired concrete driveway, it often makes sense to look at both while I'm there, and your written estimate shows exactly what's included.
How do you know your garage floor needs replacing?
Cracks that keep widening
A hairline crack is normal, but one you can fit a coin in, or one with one side higher than the other, usually means the ground under it has moved. Every season it stays open lets water and grit work in and break the edges down.
One corner sitting lower
When part of the floor drops, the ground under that spot usually wasn't packed as hard as the rest. It won't fix itself, and the longer you wait the more the slab tips and the rougher that edge gets on tires and feet.
A dusty, flaking top
If the surface comes up as powder or chips under the tires, the top was likely weak from the day it was poured, often from heat or too much water in the mix. It keeps wearing through, and patches rarely hold on a floor that's shedding its own surface.
How we pour garage floor concrete
If there's an old floor, I'll talk with you first about whether it comes out and what's likely under it, because a new slab on bad ground just repeats the old problem. Once it's out, we dig to firm ground and pack the subgrade, the dirt and gravel the slab sits on, evenly across the whole garage, and that's where most of our effort goes. Then we set forms and steel, pour, and give it a broom finish, a light texture that keeps tires and shoes from slipping when the floor's wet. We cut control joints, shallow grooves that give the slab a straight line to crack along, before it can pick its own spots. If the budget gets tight, I'd rather keep the money in the base and skip extras on top, because nobody sees the base on day one but it decides how the floor looks years from now.
Some floors need work around them too. If you want color or a pattern instead of plain gray, our decorative concrete work goes on the same slab. Where the garage is cut into a slope and dirt pushes against the sides of the driveway, concrete retaining walls hold it back so it doesn't wash onto the new floor.
Tear out and replace
This suits a floor that's cracked, sunk or flaking past saving. We break it out, haul it off and see the ground underneath before we pour, so the fix goes after the cause and not only the surface.
New floor in a bare garage
This fits a garage with a dirt or gravel floor, or a new garage on an existing house. There's no tear-out, so more of your budget goes straight into the base and the slab.
Thicker slab with rebar
A Tuscaloosa cost guide puts home slabs there at four to six inches thick, with garage floors toward the thicker end, so if you park a heavy truck or run a workshop out there, expect a quote at that end. Rebar, the steel rods set inside the slab, helps it hold together under that weight.

What happens when you call about a garage floor in Northport?
Here's how a garage floor goes from your first call to parking on it again, and who you'll deal with at each step.
Call or send the form
Tell us the size of the garage and whether there's an old floor in it. We set a time for me to come out.
I measure and check the ground
I measure, look at the old floor and the ground, and ask what you park in there. You get a written estimate that says what's included, so you can see how much goes into the base and compare it fairly with anyone else's.
We set a date and pour
Once you say go, we pick a date, take care of the permit side and form up the slab. Our crew packs the base, pours, finishes the floor and cuts the joints.
Clean up and walk it together
When the forms come off, we clean up and walk the finished floor with you. Then the slab needs its curing time before the car goes back in.
Why Northport homeowners call Northport Concrete for garage floors
I write every estimate myself
I come out, measure the garage and look at the ground before I put a number on paper. I'm also on site for the pour, so nothing gets lost between what we agreed and what gets built.
Our own crew does the pour
We don't hand the forming, pouring or finishing to another outfit. The people packing your base are the same ones who answer for how the floor holds up.
Nine years on lived-in homes
I learned concrete on new construction, then started this business in 2017 to work on houses people already live in. We plan around your cars and your yard, and we leave the yard the way we found it.
Licensed, insured and easy to check
We're licensed and fully insured. Alabama's Home Builders Licensure Board counts work on a home where labor and materials run over $10,000 as home building when the job falls under the board, so on a bigger garage job it's worth asking any contractor about their license.
On a garage floor, the base and the joints matter more than anything you see on top. When you're ready to talk about yours, send us the details or call (205) 756-6874.
Building a garage floor in Northport
Northport requires a permit for all new construction and alterations inside city limits and its police jurisdiction, with a few exceptions, and the city's building official is who issues them. I won't guess whether your garage floor falls under one of those exceptions. We check which office covers your address, and when the job needs a permit we handle the paperwork and set up the inspections. The city builds to the International Residential Code, the national rulebook for houses, with some changes of its own, so that's the standard your floor gets checked against.
Summer is the hard part of pouring here, because heat, dry air and a breeze can dry the top of a slab too fast and leave it weak. On hot days we plan the pour around the coolest hours we can get, and we work the same way on garage floors in Tuscaloosa and McCalla.
Questions about garage floors in Northport
What does a new garage floor cost in Northport, AL?
A concrete slab in the Tuscaloosa area usually costs about $5 to $11 a square foot, not counting staining or stamping. That's the going rate for slab work around here, not our price, and where your floor lands depends on its size, its thickness, any tear-out and whether it's reinforced, since steel adds to the cost. Send us the square footage and tell us if there's an old floor, and I'll give you a written number after the visit.
Will my new garage floor crack?
Probably somewhere, yes, because nobody can stop concrete from cracking entirely, but well-planned joints control where it happens and keep it small. Ask any contractor where the joints will go, since that's where the cracks should show up. Wire mesh won't stop cracks either, but it tends to keep them and the joints from opening up.
How long does a new garage floor take to cure?
Concrete takes a month to fully cure, but you can usually walk on the floor within 48 hours. Curing is the slow hardening after the pour, and the slab gains strength the whole time, so to be safe plan on keeping the car out for a week before you park on it.
What causes a garage floor to sink?
Uneven ground under the slab is the usual cause. A code guide calls ground preparation the single most important factor in how a slab performs, because soil that isn't packed evenly settles unevenly and cracks the floor no matter how thick or strong it is. That's why the base deserves a close look in any estimate you get.
What is the best way to join a new garage floor to the driveway?
Set an isolation joint, also called an expansion joint, where the floor meets the driveway, the walls and the footings. It's a gap that lets each piece move on its own, so a shift in one is less likely to crack the other.
Can I act as my own contractor on a garage floor in Alabama?
Yes, under the state's homeowner exemption, but any subcontractor you hire must be licensed if their part of the job costs more than $10,000.00. The state board also says owners who claim the exemption put at risk their right to file a consumer complaint and to be paid from the Homeowners' Recovery Fund. If you'd rather not carry that, we can run the whole job.
