Concrete Contractors in Lenexa, KS

Concrete Contractors Lenexa builds, replaces and repairs driveways, patios, stamped surfaces, sidewalks, steps and garage floors for homeowners across Lenexa, Kansas. Lenexa is a Johnson County city of 57,434 people at the 2020 census, with Shawnee to the north, Overland Park to the east, Olathe to the south and De Soto to the west. Its houses range from 1970s split-levels to subdivisions finished in the last few years, and most of them sit on clay soil that swells when wet and shrinks when dry. Good concrete contractors in Lenexa plan for that ground and for winter before they talk about finishes.

Why concrete cracks and sinks around here

Clay that moves. The Kansas Geological Survey describes expansive soils as common in Kansas wherever clay deposits sit near the surface, with soils that "heave and shrink from season to season, cracking foundations, driveways, and sidewalks." A slab poured straight onto that clay rises in a wet spring and drops in a dry August.

Freezing and thawing. On Wikipedia's climate table for Kansas City International Airport, January averages a high of 38.4 degrees and a low of 19.5, and the average freezing season runs from about October 31 to April 4. Because highs often climb above freezing, water in the concrete freezes and thaws over and over, which is what makes surfaces flake.

Water with nowhere to go. Downspouts that empty onto a drive, patios that tip toward the house and runoff that soaks under a slab edge all soften the soil beneath and feed both of the problems above.

What holds up against all three:

• A compacted crushed-rock base that separates the slab from the clay and drains
• Air-entrained concrete, which leaves tiny voids that give freezing water room to expand
• Thickness sized to the load, from about 4 inches for a walk up to 5 or 6 inches where heavy trucks park
• Steel reinforcement so cracked sections stay together and level
• Joints on a planned layout, and a slope that sends water away from the house

A city of 1970s and 1980s concrete

Point2Homes, summarizing Census survey data, puts the median year built for Lenexa housing at 1992. That median hides two big waves. About 20 percent of homes were built in the 1970s and another 19.7 percent in the 1980s, so roughly two in five houses here are 35 to 55 years old. Another 36.7 percent went up in the 2000s and 2010s.

On the older homes, the original driveways, walks and stoops are well past middle age. Typical problems are an approach broken at the curb, a front walk that has sunk away from the porch, and a garage apron that has dropped and holds water at the door. On the newer homes, the first round of trouble is usually smaller: a settled panel, a patio that has started to tip, or flaking near the street where tires carry in winter slush. Each of those can often be repaired instead of replaced, and we will tell you when that is true.

The strip by the street belongs to the city

Many homeowners are surprised by how much of the front yard is public. According to the City of Lenexa's right-of-way permit page, the right-of-way "typically extends 11 feet behind the back of curb in residential areas." The drive approach, the curb cut and the public sidewalk all sit inside it.

Any work there needs a right-of-way permit. The city requires the applicant, whether you or your contractor, to register in its online portal and carry a $10,000 bond and at least $500,000 in general liability insurance. Lenexa's residential inspection guidelines add that Engineering Services inspects drive approaches, sidewalks and curb ramps before concrete is placed, with four hours' notice at 913.477.7665. A driveway quote from us shows where your private slab ends and the approach begins, so the permit and the inspection are planned from the start.

For public sidewalks that are already failing, the city runs a Sidewalk & Trail Repair Program, which picks projects each year and has $650,000 budgeted for 2026. It is worth asking Municipal Services about your block before you pay to fix a public walk yourself.

What we pour and fix

• Concrete driveways: tear-out and replacement, widening, approaches and side parking pads.
• Concrete patios: broom, colored and exposed-aggregate patios with walks to the yard.
• Stamped concrete: slate, stone and brick patterns for patios, entries and borders.
• Sidewalks and steps: front walks, side paths, stoops and poured steps with even risers.
• Garage floors and slabs: replacement garage floors, shed and outbuilding pads, equipment pads.
• Leveling and repair: mudjacking, foam lifting, resurfacing and crack repair when the slab can be saved.

Winter pours follow city rules

Lenexa publishes its own cold-weather concrete requirements. Protection is enforced whenever the air is 40 degrees or colder, or when temperatures under 40 are forecast within 48 hours. The ground under the slab cannot be frozen when concrete goes in, and regular concrete must be kept from freezing for at least 72 hours, using blankets or a 6-inch layer of straw held down with tarps. Those rules name sidewalks and driveway approaches specifically.

In practice, most exterior concrete here goes in from spring into fall. A November pour is possible, but it costs more in protection and leaves less margin for weather. If you call late in the season, we will tell you plainly whether to pour now or wait for spring.

How a project goes

Visit and quote. We measure, check drainage and the soil under the old slab, and look at access for the ready-mix truck. The written quote lists each part of the job.

Permits and scheduling. If the work reaches the right-of-way, the permit and inspection go on the calendar first.

Tear-out and base. Old concrete or asphalt is removed, soft soil is dug out and crushed rock is compacted in layers.

Pour and finish. Reinforcement, concrete, finish and joints, all in one visit for most residential jobs.

Cure and handoff. HomeGuide's driveway guide says foot traffic is fine after 24 to 48 hours and cars should wait at least 7 days. You get those dates in writing, along with when to seal. Call (913) 355-6902 to set up a visit.

Most of our work is in Lenexa itself, on 1970s and 1980s streets and in subdivisions built in the last 20 years. We also work in the Johnson County cities around it: Overland Park to the east, Olathe to the south, Shawnee to the north and De Soto to the west, plus Merriam, Mission, Prairie Village and Leawood, and Kansas City, Kansas, across the county line. Each city has its own permit office and its own rules for work near the street, so we check what applies at your address before we schedule. The town pages cover what we found about housing and local requirements in each one.
