Walkways, sidewalks, and the one-inch lip that trips people
A sidewalk rarely fails all at once. A panel tips up on one edge after a wet spring, and now there is a lip at the joint. Then a hard freeze lifts it a little more. Then someone catches a toe on it carrying groceries. Break out an old walkway and you will often find a couple of inches of sand over clay, no steel, and joints that opened up years ago and let water in.
This page covers three jobs: new walkways, full sidewalk replacement, and trip hazard repair. The right one depends on how bad the damage is. A raised joint lip can often be ground flush in an hour. A sunken panel might be a candidate for lifting. A walk that is cracked, scaled, and sinking in several places is cheaper to replace than to keep patching.
New and replacement walks run $9 to $14 per sq ft. A 4x30 front walkway (120 sq ft) usually lands between $1,100 to $1,700. Trip hazard cutting runs $150 to $350 per spot. This work is part of our residential concrete services.
Is your sidewalk urgent, or can it wait?
Trip hazards come first because somebody can get hurt. Here is how we sort it.
Call soon if you see
- A raised edge or lip you can catch with your toe, especially anything about 3/8 inch or more
- A panel that has dropped and now funnels water toward the house or garage
- Cracks that are wide enough to hold a pencil, or edges breaking away
- A walk that ices over because water ponds on it
- Steps or a walk that deliver a visitor to a dangerous uneven landing
Usually safe to watch
- Hairline cracks that have not widened in a year or more
- Light surface wear or a little exposed sand on top
- A crack that follows a joint line, where cracks are supposed to go
- Cosmetic stains from rust, leaves, or oil
Common walkway problems and how we fix them
Raised or sunken panels
Clay under the walk swells in wet spells and shrinks in dry ones, so the panels move unevenly. Tree roots do it too. Depending on the size of the lip, we cut it, lift it, or replace it.
Scaling and spalling
The top skin flakes off and leaves a rough, pitted surface. It is usually a sign that the concrete was overworked, had water added at the pour, or was not protected from cold while it cured, or that deicers got to it. If the slab below is sound, a resurfacing job may do. See concrete resurfacing.
Cracking and crumbling edges
Edges break where a base washed out underneath. Patching the crumble without fixing the base fails again in a year or two.
Ponding and ice
A walk should slope slightly away from the house, roughly a quarter inch per foot across. A walk that holds water makes a skating rink in January. A new pour lets us correct the grade.
Your front walk is not the public sidewalk
Before any work starts, figure out which concrete is yours. The walk from your driveway or street to your front door sits on your property, and you maintain and pay for it. The public sidewalk along the street, along with the curb and gutter, is a different story. Under the city's concrete repair policy, the City of Aurora maintains the public sidewalk, curb, and gutter. You maintain your driveway, any detached driveway, and the driveway apron.
If public sidewalk in front of your home is damaged, you have two options under that policy. You can have the city repair it, or you can hire a private contractor and pay for the work yourself. Private work in the right-of-way has to meet city specs and needs a city permit. Work done without a permit can be removed and restored at the contractor's or owner's expense, so do not let anyone skip that step. We confirm the current rules with Aurora Public Works before we schedule any right-of-way work.
How the city rates displacement
The city rates sidewalk displacement, meaning the height difference between two panels, in three levels. Under 3/8 inch is low. From 3/8 to 3/4 inch is moderate. Over 3/4 inch is severe. It is a handy yardstick for your own walk too. A low rating is a candidate for grinding or cutting. A moderate or severe one may call for lifting or replacing the panel.
The five-foot rule
The city's standard minimum replacement section is five feet. On public sidewalk, a bad corner does not get a small patch. The replacement runs a full section, so plan on that when you compare a replacement quote with a repair.
Trip hazard repair: cut, lift, or replace
Cutting or grinding
When a panel is stable but one edge sits proud of its neighbor, we can saw-cut or grind the high lip down until the two meet flush. It leaves a smooth, sloped transition instead of an edge. It is quick, and it is the cheapest fix at $150 to $350 per spot. It works best on lips under about three quarters of an inch. The catch is that it only changes the edge. If the panel keeps sinking, the lip will come back.
Lifting
If the panel dropped as a whole and the slab itself is in good shape, we can raise it with mudjacking or foam. That fixes the cause, not just the edge, and it keeps your existing concrete. It is not for panels that are badly cracked or crumbling. See concrete leveling and mudjacking for how that works.
Replacing
If a panel is broken into pieces, spalled, or sinking over and over, replacing it is the honest answer. We break it out, rebuild the base, and pour a new one. Cracks without displacement are a different case. See concrete crack repair if the panel is still level.
How we build a new walkway
-
Measure and mark
We lay out the path, check where the water goes, and mark anything that crosses into the right-of-way. You get a written price before we schedule.
-
Break out and prep
Old concrete comes out, soft soil gets removed, and we compact a few inches of road base. This is the step that keeps the walk from moving again.
-
Forms and joints
Forms set the width, shape, and slope. We plan joint spacing so cracking happens at the joints and not across the middle of a panel.
-
Pour and finish
We pour 4,000 PSI air-entrained concrete about 4 inches thick, tool the joints, and finish it with a broom texture for traction.
-
Cure and seal
Walk on it the next day. Seal it after about 30 days and keep deicers off it the first winter.
What affects the price of a sidewalk or walkway
New walks run $9 to $14 per sq ft. Trip hazard cutting is $150 to $350 per spot. These are the things that move the number.
- Length and width
Short walks cost more per foot because setup does not change. Wider walks cost more but are easier to shovel and safer to share.
- Site prep
Slopes, tree roots, and soft clay add excavation and base work.
- Removing old concrete
Tear-out and haul-off run about $3 to $7 per sq ft. Replacement means that cost is part of the job.
- Finish type
Broom finish is the base price. Color or decorative concrete adds cost.
- Access
If the truck cannot reach the forms, we wheelbarrow or pump, which adds time.
- Permits and right-of-way
Private work on the public sidewalk needs a city permit and must meet city specs. We handle that process with you.
If your walk meets a stoop, check our concrete steps and stairs page, since the landing often gets replaced at the same time.
Sidewalk work through Aurora seasons
Winter
Trip hazard cutting and grinding can happen almost any dry day, which makes it the one job that works in winter. New pours need cold-weather protection, so we try to hold them for spring.
Spring
Spring is the busy season, and wet clay can delay a dig. We check the subgrade before we pour.
Summer
Hot, windy afternoons dry fresh concrete too fast, so we pour early and cure carefully.
Fall
Fall works well for replacements. Seal early and keep salt off new concrete through its first winter.
Aurora soil, salt, HOAs, and permits
Expansive clay soil
Aurora clay moves with moisture, and a thin base cannot ride it out. We dig out the soft stuff and compact real road base. Keep sprinklers and downspouts from soaking the walk edges.
Deicing salt
Salt is the number one reason walks scale. Use sand or a plastic shovel on a new walk the first winter, and seal it. See concrete sealing.
HOA approval
Many Aurora HOAs care about walkway width, location, and color. Changes to the walk's footprint often need approval first. Get it in writing before your pour date.
City of Aurora permits
Work on the public sidewalk, curb, or apron needs a city permit and must meet city specs. Your private front walk generally does not touch the right-of-way, but we confirm the details for your address with Aurora Public Works before we start.
Sidewalks and Walkways FAQs
Who fixes the sidewalk in front of my house in Aurora?
The City of Aurora maintains the public sidewalk, curb, and gutter. Under the city's concrete repair policy, you can have the city repair it or hire a private contractor at your own cost. Private work needs a city permit. Confirm current rules with Aurora Public Works.
How much does a new concrete walkway cost?
Typical pricing is $9 to $14 per sq ft. A 4x30 front walkway (120 sq ft) usually runs $1,100 to $1,700. Tear-out of the old walk is extra, at about $3 to $7 per sq ft.
How much does trip hazard repair cost?
Cutting or grinding a raised joint runs $150 to $350 per spot. Three raised joints on one walkway would typically run $450 to $1,050.
What counts as a trip hazard?
The city rates displacement under 3/8 inch as low, 3/8 to 3/4 inch as moderate, and over 3/4 inch as severe. Anything you can catch with a toe should be fixed, whatever the rating.
Can you replace just one panel?
Yes, on a private walk. On the public sidewalk, the city's standard minimum replacement section is five feet, so plan for at least that.
Is it better to lift a sunken sidewalk or replace it?
If the panel is solid and only dropped, lifting is cheaper. If it is cracked, crumbling, or keeps sinking, replace it. We tell you which one it is after we look.
