About Florissant, MO

Florissant is one of the oldest communities in Missouri, a historic city in St. Louis County, and you see that age on the job. Near Old Town the houses and trees have been there a long time. Across the rest of the city it's mostly blocks of brick ranches and split-levels, each with a driveway, a front walk and a few steps up to the door. We get calls here from homeowners, landlords and small business owners, and much of the work looks like what we do next door in Hazelwood.

On houses this age, the old concrete has often been patched more than once, and driveways tend to run tight along the side of the house. So how we break it out and get the truck close matters almost as much as the pour itself.

Services in Florissant, MO

  • Concrete driveway building

    Lots of Florissant driveways are settled and cracked after decades of freezes and cars. We tear them out, dig to firm ground and pack a new base before we pour.

  • Concrete patio construction

    Many backyards here have a small, cracked slab off the back door. We pour a larger patio that slopes away from the house so rain doesn't pool against it.

  • Concrete sidewalk building

    Front walks on older lots tend to heave or sink where runoff has washed out what's under them. We replace the bad sections and slope the new walk so water drains away.

  • Concrete steps construction

    Sunken steps pulling away from the house are a common call here. We pour new steps on footings dug below where the ground freezes, so frost has a harder time lifting them.

  • Garage floor concrete

    Garages here often have pitted, cracked floors from years of road salt dripping off cars. We break out the old one and pour a new garage floor on a packed base.

  • Concrete cutting

    On lots with big, old trees, it's often just one section a root has lifted. We saw-cut that piece out cleanly and replace it without tearing out the rest of the slab.

What to know before a concrete job in Florissant

In Florissant, the city's Building Division issues construction permits for most remodeling and handles the inspections. Its examples name things like garages, porches and patio covers rather than driveways or walks, so before any job here we check what your address needs. When a permit is needed, we file it and keep you posted. Any permit review comes before the pour, so it's usually the first thing that sets your start date. When you're comparing contractors, ask about the city business license, because Florissant only issues one to a business that's registered with the state. We're licensed and insured, and our work is backed by our satisfaction guarantee.

Price here mostly turns on what's under and around the slab. That means how much old concrete we break out and haul off, how deep we dig to reach firm ground, how big the pour is and how close the truck can get. Rebar, the steel inside that keeps a slab together if it cracks, adds cost, and so does a stamped or colored finish. If a budget has to give, I'll suggest a plain broom finish, the light texture that gives your shoes grip when it's wet, before I'll thin out the base. I spent years fixing driveways that failed from the bottom, and nobody can get to the base once it's covered. Your written estimate lists each of those parts separately. The schedule turns on the permit, the weather and the curing time, the wait while the concrete hardens before you use it. It's the same way we work across the river in St. Peters.

Florissant, MO properties and local conditions

Winters here keep crossing the freezing mark. Each time, water that's soaked in under a slab freezes and pushes up, then lets go when it thaws. That's why so many driveways and walks we look at in Florissant have tipped and cracked. It's worst where a downspout empties onto the concrete or the slab was poured flat or tilted toward the house. Before we pour, I check where your water actually runs, and we slope the new concrete away from the house. Concrete cracks as it shrinks, so we also cut control joints, shallow grooves that give the slab a planned place to crack. We cut them the same day we pour, because a slab left waiting starts picking its own cracks, and that's how you end up with one running across the middle of your driveway.

Under a lot of older concrete here we find dirt that was raked level and poured on, and it's been settling ever since. We dig that out to firm ground and pack gravel in layers. The subgrade, what the slab sits on, has more to do with whether your new driveway stays flat than anything we do on top.

What happens after you call us about a Florissant job

  1. Call or send a message

    Call (636) 277-0973 or use the form and tell us what you want poured or replaced. We'll set a time for me to come out to your place in Florissant.

  2. Walk the site together

    I look at the old concrete, the ground and where your water goes, and I ask how you'll use the slab before I offer any options. If you can be there, it's the best time to ask about cost, because I'll explain what each choice adds and why.

  3. Clear the permit, then pour

    Once you say yes, we check what your address needs from the city, and when a permit is needed, the city's general estimate is 7 to 10 days from application to permit. After that our crew lead runs the job, from digging out and packing the base to the pour, the joints and cleanup.

  4. Walk the finished job

    When the crew's done, I walk it with you and go over how to look after it. That includes keeping cars off until it's cured and what to put down for ice that first winter instead of rock salt.

Frequently asked questions

Do I need a permit to replace a concrete driveway in Florissant?

Ask the city before anything is poured. Florissant requires permits for most remodeling, and its published examples don't settle driveway work one way or the other. To check your own project, call the public works office at 314-839-7648. On our jobs, we make that check before anything gets scheduled.

How do I apply for a building permit in Florissant?

You apply online, because Public Works asks that all permit applications go through its self-service portal. The applicant has to be at least 18 and an authorized agent of the property owner. When one of our jobs needs a permit, we do that filing.

Which building code does Florissant use for concrete work at a house?

Florissant uses the International Residential Code, a model code for homes, with its own local changes, and any permit the city approves now has to meet those changes. If your job needs a permit, the city's inspections check the work against those rules, so I plan the job around them from the first visit.

How much does a new concrete driveway cost in Florissant?

There's no fair number until I've seen your driveway, because the tear-out, the base and the finish move the price as much as the size does. Breaking out a thick old slab costs more than pouring where there was only grass, and a plain broom finish on a well-packed base costs less than stamped or colored concrete. Call (636) 277-0973 and I'll come take a look.

What is the best time of year to pour concrete in Florissant?

Spring and fall are usually the easiest times to pour here, because concrete cures more evenly when it isn't baking in the sun or sitting near freezing. We still pour in summer, but we start early so we're not finishing the surface in midday heat, which can leave a weak, dusty top. When a cold snap is coming, we wait or cover the slab.

How long does a new concrete driveway take before I can drive on it?

You can walk on new concrete well before you can drive on it, and I'll give you both dates for your pour, because cool weather slows curing down. Parking on it early is one of the easiest ways to crack a new driveway, so plan on parking somewhere else for that stretch.
