Concrete Maintenance Schedule: A 12-Month and Multi-Year Plan for Wisconsin Homes

Your furnace gets a new filter. Your car gets an oil change. Your driveway gets nothing until a slab drops or the apron starts flaking.

Concrete doesn't ask for much, but it needs the right things at the right time. In northeast Wisconsin, frost, snowmelt, and road salt set that timing, which is why a generic list misses the point.

Here's the whole plan: a monthly calendar, what changes as a slab ages, the jobs that come around every few years, a printable checklist, and a simple way to keep records. For most homes it adds up to a few hours a year.

The 12-Month Calendar

The temperatures are Green Bay's 1991–2020 normals. They matter because most joint sealants and penetrating sealers want about 40°F and up, and lifting needs thawed ground.

March through June has its own step-by-step guide: our spring concrete maintenance checklist. November through February, including which deicers to keep off concrete, is covered in winter concrete care. With about 56 inches of snow in a normal Green Bay year, it's worth reading. Here's what neither guide covers.

July and August: The Easy Stretch

Summer asks the least of your concrete, so use it to spot problems.

• ✓Treat weeds in a joint as a symptom. If something is growing there, the joint is open to water. Pulling the weed is cosmetic. Sealing the joint is the fix, so note it for September.
• ✓Sweep fertilizer back onto the lawn right after spreading. Iron in fertilizer leaves orange rust specks, and ammonium-based products can etch the surface.
• ✓Blot oil drips while they're fresh. A week-old drip is a quick cleanup. A two-year-old stain may never fully come out.
• ✓Run the water test in August. Sprinkle water on sealed concrete. If it beads, you're set. If it darkens and soaks in, reseal this fall. See should you seal your concrete.

September and Early October: The Window That Matters Most

Green Bay's normal low is about 50°F in September, 40°F in October, and below freezing in November. That leaves roughly six weeks to close joints and get sealer on before the salt trucks roll.

Plan backward from the first cold nights. Say you want sealer on by October 5. Polyurethane joint sealant takes about a week to fully cure, and caulk goes in before a penetrating sealer, so caulking needs to wrap up by late September. Cleaning comes before that, plus at least a day of drying. Start in mid-September and you're comfortable. Start October 1 and you're gambling.

While you're out there:

• ✓Fill washouts along slab edges with soil, tamp it, and slope it away. The national model code for new homes calls for at least a 6-inch drop in the first 10 feet from the foundation, a good target for any house.
• ✓Reattach downspout extensions the mower knocked loose. (How to extend downspouts)
• ✓Put in driveway markers before the ground freezes, so the plow finds the edge of the slab instead of chewing it.
• ✓Get wet leaf piles off concrete. They leave tea-colored stains, especially on light concrete.

Maintenance by Age

A brand-new slab and a 25-year-old slab need different things.

The first year sets your baseline. Photograph the slab new from fixed spots. Skip deicers the first winter and use sand. Seal after it cures: sealer labels we checked typically want 14–28 days, and the weather has to fit the label, so a late-October pour gets its first seal the next late summer. Keep dumpsters and moving trucks off the edges, a slab's weakest part. Hairline shrinkage cracks are normal. A slab that drops near the house after its first thaw isn't, so call your installer while the warranty is good. See new concrete cracking.

Years 2–5: watch the house side. The soil around your basement was backfilled after the walls went up, and it keeps compacting for years. Stoops, aprons, AC pads, and walks along the foundation sit right on it. Check them with a level every spring, and re-check the grade, which settles along with the backfill.

Years 5–15: the cycles kick in. Your first reseal and re-caulk usually come due, stains add up, and sinking tends to show near downspouts. A slab that's down 1/2" is a quick fix. Let it drop for five more springs and the void under it is a lot bigger.

15 years and up: decide area by area. A solid driveway with light scaling is worth maintaining. A patio broken into six pieces isn't. Our guide to restoring old concrete walks through that call.

The Jobs That Come Around Every Few Years

A Worked Example: 12 Years on One Driveway

Here's how those intervals play out on a two-car driveway poured in June 2026, assuming the sealer lasts about six years. Your products and exposure will change the numbers. The yearly water test tells you when.

Notice caulking and sealing happen in the same season. Joint sealant goes in before a penetrating sealer, and one silane maker's data sheet says to test adhesion if you reverse the order. Lining the cycles up keeps the order right and saves a trip.

The Yearly Inspection Checklist

Print this and run it once a year after the frost is out, with a quicker pass in late August. Bring a tape measure, a 2-foot level, a screwdriver, and your phone. Most homes take 20–30 minutes.

Along the house

• ✓[ ] The gap where concrete meets the foundation is sealed
• ✓[ ] Slabs next to the house tip away from it (check with the level)
• ✓[ ] Soil along the foundation slopes away, with no low spots
• ✓[ ] Downspouts and the sump discharge drain onto lawn, away from concrete

Driveway and apron

• ✓[ ] No edge between slabs higher than 1/4"
• ✓[ ] The apron meets the garage floor without a lip, and water runs away from the door
• ✓[ ] Joints are sealed, with no splits or weeds
• ✓[ ] No new flaking, popouts, or plow gouges

Front walk, stoop, and steps

• ✓[ ] No trip edges over 1/4"
• ✓[ ] The stoop sits level or tips slightly away, with no gap at the house
• ✓[ ] Corners sound solid when you tap them with the screwdriver handle
• ✓[ ] No animal burrows under slab edges or the stoop

Patio

• ✓[ ] No standing water an hour after rain
• ✓[ ] No corners that rock underfoot

Garage floor

• ✓[ ] No cracks that are new, widening, or offset
• ✓[ ] Coating (if any) is intact

Sealed surfaces

• ✓[ ] Water still beads

Anything over 1/4" goes in your log. Anything over 1/2" is a trip hazard worth fixing soon. That's the same yardstick accessibility rules use for walking surfaces.

Keep a Concrete Log

A notebook, a spreadsheet, or a notes app all work. What matters is writing the same few things every time.

• ✓Shoot from the same spot every time, with a tape measure in the frame for anything that has a height difference.
• ✓Name photos by date and place, like 2027-04_front-walk.jpg, so you can find them in five years.
• ✓Record products and dates. The sealer type and the day it went on tell you when to start water-testing. Keep receipts with the log.

The log tells you whether something is moving or just looks bad, and it makes photo quotes faster. It helps when you sell, too: Wisconsin requires sellers of most one- to four-unit homes to fill out a Real Estate Condition Report covering defects they know of, and a record of what you found and fixed makes that easier to do honestly. Ask your agent what needs disclosing.

What Maintenance Can't Fix

A schedule keeps good concrete good. It won't reverse damage that's already done.

And most of this schedule, you don't need us for. Rinsing salt, weeding joints, fixing downspouts, and caulking a few level joints are homeowner work. Call when a slab has sunk, the joint footage is more than you want to tackle, or the whole driveway needs a clean and seal.
