Why people around Alexandria call us
Concrete is hard to undo, so the crew you hire should think the job through before the truck shows up and be straight with you about what it needs. Here's what that means with us.
Built for what sits on it
I spent years framing houses on other people's slabs and footings, so we plan each slab, wall or footing around the weight and use it has to carry.
Base before finish
If the budget's tight, cut the finish, not the base, because a nice surface on loose dirt still settles and cracks, and the base can't be fixed later.
Hard questions up front
You'll hear the hard questions early, like where the water goes and what's under the old slab, so surprises turn up on paper, not in your yard.
Honest about smaller fixes
When a new surface or raising a sunken slab will do the job, we'll tell you that instead of selling you a full tear-out.

Concrete services in Alexandria, VA
J&K Alexandria Concrete Company is a concrete contractor in Alexandria, VA, with 16 services, from new driveways and patios to footings, foundations and cutting into old slabs. Most calls start with a slab that's cracked, sinking or holding water, or with something that doesn't exist yet. The price mostly turns on size, thickness, how much old concrete has to come out and be hauled away, the base work the ground needs and the finish you choose. The schedule turns on the permit and on curing, the wait while new concrete gains strength before you can use it. Your written estimate spells out what's included for your job.
Concrete driveway building
We dig out, pack the base and pour driveways sized for your cars, then cut control joints so any cracking follows lines we picked.
Learn moreConcrete patio construction
Want an outdoor spot for the grill and a table? We pour patios sloped away from your house, so rain runs to the yard, not your basement.
Learn moreStamped concrete services
Stamped concrete gets pressed with a pattern and colored while it's fresh, so a patio or walkway looks like stone or brick without laying pieces one by one.
Learn moreConcrete sidewalk building
Uneven sidewalk tripping people up? We replace the bad sections and pour new walkways with a broom finish, a brushed texture that gives shoes grip.
Learn moreGarage floor concrete
We pour garage floors for cars, tool chests and workbenches, finished smooth enough to sweep and pitched slightly so water off a wet car runs toward the door.
Learn moreDecorative concrete
Decorative concrete covers color, stains, stone showing through the surface and custom edges, for homeowners who want a patio or entry that looks finished rather than plain gray.
Learn moreConcrete retaining walls
When a slope keeps washing into your yard or driveway, we build poured concrete retaining walls with drainage behind them so water doesn't push the wall over.
Learn moreConcrete floor installation
We pour interior concrete floors for basements, workshops and additions over a packed base and vapor barrier, so ground moisture stays out of the room.
Learn moreConcrete pool decks
What makes a good pool deck? A surface wet feet can grip, a slope that drains away from the water and joints planned around the pool's edge.
Learn moreConcrete steps construction
Crumbling or uneven front steps? We form and pour new ones with every step the same height and rebar, steel bars inside that keep a crack from spreading apart.
Learn moreSlab foundation building
We build slab foundations for additions, garages and sheds, starting with the subgrade, the packed ground the slab sits on, since everything above depends on it.
Learn moreFoundation installation
We form and pour foundation walls for additions and new buildings, set square and level so the framing crew starts on something true.
Learn moreConcrete parking lot building
For shops, offices and small apartment buildings, we pour concrete parking lots with a thicker slab and a base built for daily traffic and delivery trucks.
Learn moreConcrete footings
Footings are the wide concrete pads under walls, posts and decks that spread the weight into the ground. We size them for what sits on top.
Learn moreFoundation raising
Is part of your slab or foundation sinking? We raise and level settled concrete when it's still sound and tell you plainly when it isn't.
Learn moreConcrete cutting
We saw-cut concrete for new doorways, plumbing trenches and partial removal, and check what might be buried in the old slab before the blade goes in.

How a concrete job goes with us
Call or send the form
Call (571) 760-4255 or fill out the contact form with your address and what you've got, whether it's a cracked walk, a sinking slab or something that isn't built yet. We reply within one business day to set a time for me to come out.
I walk the job
I come out myself, look at what's there and ask a lot of questions, like what's under the old concrete, where the water runs and what the new slab has to carry. You get a free written estimate with no obligation that spells out what's included, such as removal and haul-away, so you can compare it fairly with other bids.
Paperwork, then the pour
Before we set a pour date, we find out which city or county office covers your address and take care of the permit work for our part of the job. If anything needs your signature, you'll hear it up front. Then our own crew forms, pours and finishes the concrete.
Final walk-through
When the work's done, I walk the finished job with you so you can see the slope, the joints and the finish and ask whatever's on your mind. I'll also tell you when it's ready to walk on and when it can take a car. Your satisfaction, guaranteed.
Concrete questions we hear most
Here are straight answers to what people around Alexandria ask before they hire us. If your job has a twist these don't cover, ask, because those are the ones I like.
How much does a new concrete driveway or patio cost in Alexandria, VA?
There's no honest single number, because size, thickness, tearing out the old slab, base work and the finish you choose all move the price. I give you a figure in writing after I've walked the job and seen what's under there, so ask for an estimate and you'll have it.
Why do concrete quotes vary so much between contractors?
Usually because the bids don't cover the same work, especially the base, the removal and haul-away of the old concrete, and how the joints are cut. A low bid often rakes the dirt level instead of digging out and packing a real base, and that's the part nobody sees on day one. Our estimate lists what's included so you can compare line by line.
How long before I can drive on a new concrete driveway?
You'll walk on it well before you drive on it, because the slab keeps curing and gaining strength for days after the pour, and a car weighs a lot more than you do. The exact wait depends on the mix and conditions on pour day, so I'll give you the dates for your job before we pour and you can plan where to park.
Do I need a permit for concrete work in Alexandria, VA?
Often, yes, because the City of Alexandria requires permits for most construction work, and its list includes retaining walls holding 2 feet or more of soil, stoops, private pools, and garages or sheds over 200 square feet. A driveway or patio isn't named on that list, so we check what your job needs with the city's Permit Center before we set a pour date.
What happens on the day concrete gets poured?
By the time the truck arrives, our crew has the old concrete out, the ground dug out, the base packed and the forms set, so the pour itself goes quickly. Then we place, level and finish the concrete and cut the control joints before it hardens too far, since joints cut late leave cracks in places nobody chose. We aim to pour early in the day, because concrete finished in midday heat can end up with a weak, dusty top.
Will my new concrete crack like the old one did?
Some fine cracking is normal in any slab, but a packed base, rebar where it's needed and control joints cut on time keep cracks small and in the lines we chose. If you see a crack that keeps widening, a section that sinks or water pooling where it didn't before, call (571) 760-4255 and tell us what you're seeing.
Should I get stamped concrete or a plain broom finish for my patio?
Pick the look you'll be happy with for years, because both last when the base under them is done right. Stamped costs more since it's colored and pressed by hand, and a plain broom finish is easier to patch or match later. If the budget won't stretch to both, I'd spend it on the base and keep the top simple.
How do I know if my Alexandria address is in the city or the county?
Start with your ZIP code, because some Alexandria mailing addresses actually sit in Fairfax County or Arlington County, and that decides which office handles the permit. ZIP codes 22301, 22305, 22313 and 22314 are entirely in the city, while 22302, 22304, 22311 and 22312 are shared with Fairfax County and 22206 with Arlington County. If you're in a shared ZIP, we confirm which office covers your address before we quote.
