Concrete Sidewalks in Pittsburgh, PA — Installation, Repair & ADA Ramps
Ever caught your toe on the same raised slab twice in one week? That’s not clumsiness — that’s a sidewalk telling you something moved underneath it, and around here, it rarely stops on its own.
We build, repair and replace concrete sidewalks for homeowners, landlords and business owners throughout Pittsburgh and the surrounding Allegheny County boroughs. New walkways, broken panels, trip hazards, ADA ramps, steps and curbing — it all runs through one crew and one written scope.
Sidewalk Services We Handle Across Pittsburgh
Every walkway problem lands somewhere on a spectrum: a hairline crack on one end, a full tear-out on the other. Here’s how the work breaks down, and where your project probably fits.
New Sidewalk Installation
Adding a front walk, connecting a side entry to the driveway, or replacing a worn brick path with something that holds up to a Pittsburgh winter — new pours start with the base, not the concrete. We set the route, cut the grade so water sheds away from the house, compact a proper aggregate base, then form and pour.
Control joints get spaced so the slab cracks where we tell it to. Finish is usually a broom texture for traction on wet mornings.
Sidewalk Repair & Replacement
Most calls we get start here. A single panel has dropped, roots have lifted a section, or the surface is flaking off in sheets after years of salt.
Not every one of those needs demolition. Sometimes a panel gets ground down, sometimes it gets lifted back to grade, and sometimes the base is gone and the honest answer is a fresh pour. We walk it panel by panel and tell you which is which.
Commercial Walkways
Storefront frontage, apartment complexes, office parks, churches and HOA-managed developments all share one headache: foot traffic doesn’t stop while you fix the concrete.
We phase commercial walkway work so entrances stay usable, and we build to the specs an inspector will actually measure — slope, width, joint layout and drainage. Property managers get a scope in writing before anything gets broken up.
ADA Ramps & Compliance
Curb ramps, detectable warning panels and beveled transitions aren’t decorative — they’re measured. A quarter-inch lip is the line between a finished walkway and a documented trip hazard.
We install and correct ADA curb ramps, truncated dome panels and cross-slope issues on both public frontage and private commercial property, from parking lot connectors to building entries.
Concrete Steps & Curbing
Pittsburgh’s terrain means a lot of walkways don’t stay flat for long. Stepped runs, landings, stoops and retaining edges are part of the same pour on plenty of properties in the South Hills and along the city’s slopes.
We also handle curb work and driveway aprons, including the curb cut portion where the sidewalk meets the street.
Why Pittsburgh Sidewalks Crack, Sink and Heave
Concrete doesn’t fail randomly. In this region it fails for four fairly predictable reasons, and knowing which one you’re dealing with changes the repair entirely.
- ✓Freeze-thaw cycling. Water works into the slab, freezes overnight, expands, and thaws by afternoon. Repeat that dozens of times a season and the concrete pulls itself apart from the inside — especially if the original mix wasn’t air-entrained.
- ✓Road salt and deicers. Chloride attacks the surface paste. You get scaling first, then spalling, until the aggregate is sitting exposed like gravel glued to the top of the slab.
- ✓Tree root heave. Mature street trees in Squirrel Hill, Shadyside, Highland Park and Regent Square send roots straight under the walk. The slab lifts, the joint opens, and the panel tilts.
- ✓Base failure and hillside settlement. Washed-out subbase, loose utility backfill, or a slope that never got compacted properly. The concrete is fine — the ground under it gave up.
That last one matters most. Pour a beautiful new panel over a bad base and you’ll be looking at the same problem in three winters, which is why we dig into the cause before quoting the fix.
Repair, Replace or Level — How to Tell What Your Sidewalk Needs
You don’t need to diagnose it yourself, but it helps to know the options before anyone shows up with a quote. Here’s the shorthand we use on site.
| What you’re seeing | Likely fix | What’s involved |
|---|---|---|
| Hairline cracks, open joints | Crack and joint repair | Rout, clean, seal — no demo |
| One panel lifted ¼” to 1″ | Grinding or beveling | Trip hazard removed, slab stays |
| Panel sunk, hollow underneath | Slab lifting | Voids filled, panel raised back to grade |
| Surface flaking, stone showing | Resurfacing or overlay | Bonded topping over sound concrete |
| Multiple broken panels, root damage | Panel or full replacement | Demo, root work, new base, fresh pour |
Cheapest fix isn’t always the right one, and the most expensive isn’t either. If a panel can be saved, we’ll say so — related work like concrete leveling, crack repair and spalling and surface repair often costs a fraction of a tear-out.
Sidewalk Permits and Property-Owner Responsibility in Pittsburgh
Here’s the part that surprises most homeowners: the sidewalk out front sits in the city’s right-of-way, but keeping it in safe condition falls to the adjoining property owner under the Property Maintenance Code. That’s why the notice comes to your mailbox and not the city’s.
- ✓Work on a sidewalk, curb or driveway apron inside the public right-of-way requires a permit from the Department of Mobility and Infrastructure (DOMI).
- ✓The contractor pulling that permit has to be registered as a general contractor with the City and carry insurance on file.
- ✓Curb cuts — the apron where a driveway crosses the walk — run on their own permit track, classified as residential or commercial depending on the property.
- ✓Suburbs run their own show. Mt. Lebanon, Bethel Park, Ross, Shaler and Monroeville each have their own sidewalk ordinances and notice procedures.
- ✓Utility work leaves marks. After a Pittsburgh Water line repair, the patched section often needs proper restoration rather than the temporary fix left behind.
Got a notice with a deadline on it? Bring it to the walkthrough. We’ll read the scope it’s asking for, tell you which permit path applies, and lay out a timeline that fits the date on the letter.
ADA Trip Hazards, Curb Ramps and Walkway Compliance
Compliance work is where guesswork gets expensive, because everything on this list is checked with a tape measure and a level. For commercial frontage, apartment walkways and HOA-managed paths, these are the numbers that decide pass or fail.
- ✓A vertical change over ¼ inch counts as a trip hazard. Up to ½ inch is acceptable only when it’s beveled at 1:2 or flatter.
- ✓Curb ramp running slope tops out at 1:12 — one inch of rise for every twelve inches of run.
- ✓Minimum clear width on a curb ramp is 36 inches.
- ✓Cross-slope on the walking surface stays at 1:48 or less, which also keeps water moving instead of ponding.
- ✓Detectable warning panels extend 24 inches in the direction of travel, across the full ramp width.
We correct existing violations and build new ramps to those specs on retail frontage, office parks, medical buildings, churches and multi-family properties across the region. If the walkway serves the public, it’s worth measuring before someone else does.
How a Pittsburgh Sidewalk Project Runs, Step by Step
No surprises is the whole point. Every job follows the same five stages, whether it’s two panels or two hundred feet.
01. On-site assessment
We walk the full run, check grade and drainage, note root activity and base condition, and photograph what we find.
02. Scope and permit path
You get the work spelled out in writing, plus a straight answer on whether a DOMI or borough permit applies and who files it.
03. Demo and base prep
Old concrete comes out, roots get addressed so they don’t come back, aggregate base goes in and gets compacted, forms are set to line and grade.
04. Pour and finish
Air-entrained mix for freeze-thaw durability, control joints cut at proper spacing, broom finish for traction, tooled edges.
05. Cure and cleanup
We cover protection time, when foot traffic is fine, when vehicles are fine, and we leave the site cleaner than the concrete truck found it.
That third step is the one plenty of crews rush. It’s also the one that decides whether your walkway lasts through a decade of winters or starts telegraphing cracks by year three.

Frequently Asked Sidewalk Questions
Do I need a permit to replace my sidewalk in Pittsburgh?
If the work sits in the public right-of-way, yes — DOMI issues the permit, and the contractor filing it must be registered with the City. Suburban boroughs have their own process. We identify which applies during the assessment and handle the filing.
The city sent me a sidewalk repair notice. What's my first move?
Read the deadline, then get the walkway assessed before it passes. The notice usually specifies which panels are flagged. We match the scope to the letter so the corrected work satisfies what was cited the first time.
Can my sidewalk be repaired, or does the whole thing need replacing?
Depends on the base. If the ground underneath is solid and only the surface or elevation is off, grinding, lifting or resurfacing usually works. If the subbase has washed out or roots have broken multiple panels, replacement is the durable answer.
How long before I can walk on new concrete?
Foot traffic is typically fine after a day or so, depending on temperature and mix. Vehicles need considerably longer. We give you exact timing for your pour and mark off the areas that need to stay clear.
How many days does a sidewalk project take?
Most residential walkways wrap up in one to three working days once demo starts. Larger commercial runs get phased. Permit processing and weather windows are usually the bigger variable, not the concrete work itself.
A tree root lifted my slab. Will cutting it kill the tree?
Not usually, when it’s done right. Selective root pruning at the correct distance from the trunk lets most mature trees keep going. On protected street trees we work within what the municipality allows.
Can concrete be poured in winter?
It can, with cold-weather measures — blankets, adjusted mixes and protected curing. That said, if your project can wait for a better window, the finish quality and cure conditions are simply easier to control.
What height counts as a trip hazard?
Anything over a quarter inch of vertical change. Between a quarter and a half inch it’s acceptable only if properly beveled. Above that, the section needs grinding, lifting or replacement to be considered corrected.
Can I use rock salt on a new sidewalk?
Not the first winter. Fresh concrete hasn’t fully gained strength or sealed up, and chlorides will pit the surface fast. Sand for traction that first season, then switch to a calcium-magnesium-acetate product afterward.
Do you handle driveway aprons and curb cuts too?
Yes. The apron and curb cut are part of the same right-of-way, so it makes sense to do them together with the walkway. That work often ties into a driveway project as well.
