Winter is the honest season for a driveway. Snow melt shows you where water sits. Ice shows you which joints have lifted. A February freeze shows you which cracks are moving. If you walk the driveway with this checklist now, you'll know by March whether it needs replacing this spring — and if it does, you'll be ahead of everyone who figures it out in May. I'm Bryan at ZBL Concrete & Design in Lockport; here's what I look for across Will and DuPage County.
Why Check It in Winter
1. Cracks you can fit a quarter into. Hairline cracks are normal. A crack wider than a quarter inch, or one you can see daylight through at the edge, goes all the way through the slab. Once it's through, water gets under the driveway, freezes, and the crack grows every winter. Check the edges first; that's where it starts.
The 7-Point Checklist
2. Spider-web cracking. A network of cracks across a section — like a cracked windshield — means that section has no support underneath. It's the signature of a driveway poured without a gravel base or without rebar, which describes most driveways in our area older than 25 years.
3. Sunken or lifted slabs. Put a straightedge (or a snow shovel handle) across any joint. A lip of half an inch or more, in either direction, means the base has shifted or washed out. This is also the one most likely to cause a fall on ice, and the one most likely to catch a snowplow blade.
4. Water that doesn't leave. After a melt, look for puddles that are still there the next morning, especially against the garage slab or the foundation. Standing water means the slope is gone, and standing water against the house is a basement problem waiting to happen.
5. Surface flaking (spalling). If the top layer is peeling off in thin plates and you can see the aggregate, that's freeze-thaw and salt damage. Once it starts it spreads every year, and there is no finish that bonds reliably to a spalled surface.
6. Age. If the driveway is over 25 years old and showing any two of the above, it's done. A well-built driveway lasts 30 to 40 years; an unreinforced one from the 1990s is at the end of its life.
7. The screwdriver test. Find the widest crack. If you can push a flat screwdriver into it an inch or more, or wiggle it and feel the slab edge move, the base under that section has failed. Nothing applied on top fixes that.
Replacement in 2027 runs $13 to $16 per square foot from us, tear-out included. A 600 sq ft two-car driveway is $7,800 to $9,600; 1,000 sq ft is $13,000 to $16,000. That's demolition and hauling, excavation, 4–5 inches of compacted gravel, rebar on 2-foot centers, a 4-inch pour (5 at the apron), broom finish, saw-cut joints and sealer. Two days on site for most driveways; drive on it after 30 days. Full scope on the concrete driveways page, and you can run your size through the cost estimator.
What Replacement Costs in 2027
If you've been quoted mudjacking, polyjacking or an overlay, here's my honest take: we don't do any of them. Not because they never work, but because on a driveway that checks two or more boxes above, the base has failed, and lifting or coating a slab on a failed base buys one to three years. A new slab on a real base buys thirty. If your driveway checks none of the boxes and you just want it to look newer, a sealer is $200 to $400 and we'll tell you that at the estimate. See why we replace instead of repair.
Repair, Level or Replace?
If the checklist says replace, here's the winter to-do list. Measure the driveway — length times width, including the apron — so you can run it through the estimator and know the ballpark before anyone comes out. Take photos of the worst cracks and the puddles after a melt; they're useful at the estimate and for the permit drawing. Find your plat of survey. Check whether your HOA needs to approve (most in Plainfield and Naperville do). Then get the estimate in December or January, so the permit is filed in February.
What to Do Between Now and April
Tear-out day, so you know what's coming: the crew arrives around 7, a skid steer with a breaker takes the old slab apart in a couple of hours, a dump truck hauls it (expect two to three loads for a two-car driveway), then we excavate, grade and compact the gravel. Park on the street that night and the next. Pour day the truck arrives early, the slab is finished by early afternoon, and we saw the joints the next morning. Thirty days later you're parking on it, and the sealer goes on around then too.
Booking It for Spring
If the checklist says replace, do the estimate now. Winter quotes lock the price for spring, winter bookings pour first in late April, and we file the village permit (Lockport, Plainfield, Joliet and most others require one for a driveway) in February so it's not holding things up in May. How spring booking works. Bolingbrook homeowners can start on our Bolingbrook page — and if you're in Lockport, Homer Glen, Romeoville or Crest Hill, we're ten minutes away.
