Concrete in St. Louis, Missouri
In the city proper, the hardest part of a concrete job is frequently getting to it. Dense platting, rear garages and service alleys mean the route matters as much as the work.
The city of St. Louis is an independent city, administratively separate from St. Louis County that surrounds it on three sides.
The second thing that separates the city is age. A great deal of flatwork here predates the conventions a modern crew would apply to it.
What is different about concrete in the city of St. Louis
City lots were platted narrow and deep, with a service alley behind and often a detached garage at the rear. That produces a driveway shaped like a corridor: long, narrow, squeezed between a house wall and a property line, sometimes with a gangway that a wheelbarrow fits through and nothing larger. Whether a machine can reach the far end of that corridor is a genuine constraint, and it is the question that most often separates two quotes that appear to describe the same job.
The alley itself is part of the equation. Where the alley is the access route, its width, its surface and the clearance above it decide what equipment can be brought in. A crew that has to hand-barrow material the length of a lot is pricing labour that a crew with alley access for a truck is not, and neither is wrong — they are solving different problems. Asking each bidder to say out loud how they plan to get in makes the difference visible instead of buried.
Public walks along city frontages are frequently old, and in places they abut granite kerbing that predates the concrete beside it. Responsibility for that frontage flatwork is set by the city rather than assumed, and it decides both who pays and whether cutting is permitted. It is worth resolving before commissioning anything, because a homeowner who repairs a panel that was never theirs has spent money and gained nothing they can point to.
The masonry building tradition here shows up as front steps and stoops on a very large share of houses. Those assemblies deteriorate at their nosings and exposed edges long before their bulk is compromised, so a set of steps can look alarming while remaining structurally intact, and can equally look tidy while hiding movement at the joint where it meets the building. Neither judgement can be made from the pavement.
Where flatwork is genuinely old, surface condition and elevation have usually both moved, and that combination is what argues for removal rather than correction. Lifting concrete whose surface is already breaking down restores the height of something that needs replacing anyway. This is the least ambiguous decision in the whole metro, and it belongs to the oldest neighbourhoods in it.
What comes up most in St. Louis
Corridor driveways between house and property line
A long narrow run changes how material and machines reach the work. Ask each contractor to state their access plan; it explains more price difference than the slab spec does.
Alley-dependent equipment access
Where the alley is the only route, its width and clearance set the scope. A crew hand-barrowing the length of a lot is pricing something different from one backing a truck in.
Frontage walk responsibility on old streets
Old public walks along city frontages may not be yours to cut. Settle ownership with the city first — repairing somebody else's panel buys nothing.
Step and stoop assessment on masonry-era houses
Steps fail at nosings and edges first, and hide movement at the building joint. Looks are a poor guide in both directions here.
The wider St. Louis picture
Winters here cross the freezing point repeatedly rather than settling below it for a season, and that pattern is harder on concrete than sustained cold. Each crossing acts on whatever moisture the surface has taken in, and a wet surface cycling through freezing many times over a winter deteriorates faster than a dry one that freezes hard once. De-icing chemicals in regular use on roads and drives add to that, particularly where meltwater carrying them stands rather than draining.
Services covered in St. Louis
Concrete leveling
Raising settled slabs back toward their original height instead of tearing them out.
Polyjacking (foam injection)
Polyurethane foam injection: light, fast-curing, small holes — and more expensive per unit of material.
Mudjacking (slabjacking)
Cementitious slurry lifting: long-established, cost-effective on volume, heavier, with larger patched holes.
Replacement and new flatwork
Removing failed concrete and pouring new — plus what separates a good pour from one that fails early.
Resurfacing and overlays
A new wearing surface over sound concrete — and the movement problems it cannot fix.
Sealing and coatings
Sealers, epoxy and garage-floor systems: what they protect against and what they do not.

What coverage in St. Louis means today
ConcreteOwner covers the St. Louis metro as a homeowner resource today. Whether we can route your request to a contractor depends on whether one has been recorded for the specific service category you need, and no territory in this metro is currently represented as held by anybody. If nobody is on record for your request, we will say so plainly rather than passing your details to a company that does not do the work.
Questions from St. Louis metro homeowners
My St. Louis house has a rear garage off the alley. Does that change the job?
Often substantially. The alley may be the only viable route for equipment and material, which makes its width, surface and clearance part of the scope rather than a detail. Ask any contractor how they intend to reach the work and what happens if the alley cannot take their machine — the answer can move a price more than the slab specification does.
Is old city flatwork worth repairing or should it be replaced?
It depends on whether the concrete has failed or only moved. Flatwork that has dropped as a sound unit can be corrected; flatwork whose surface is breaking down as well as sitting low is failing, and restoring its height buys nothing lasting. Establish which of those two you have before you ask anybody for a number, because the two answers differ by a large multiple.
Why do my front steps look worse than my driveway of the same age?
Because steps present far more edge per unit of area, and edges are where concrete is most vulnerable to freezing, salt and impact. A step assembly also takes concentrated foot traffic on its nosings. Steps commonly need attention while flatwork of identical age is still sound, and that is normal rather than a sign the original work was poor.
Who is responsible for the public sidewalk in front of my house?
That is set locally and differs across the municipalities in this metro, so we cannot answer it for your address. It determines who pays and whether permission is needed before anything is cut, which makes it worth one call to your city before you commission work on a walk that may not be yours to alter.
Do you have contractors in St. Louis right now?
No territory in this metro is currently recorded as held. You are welcome to send a request and a person will read it, but we will not tell you somebody is on the way when nobody has been assigned. The decision tools and standards on this site cost nothing and are useful either way.
