About Saint Charles, MO

Saint Charles is home for us, so a lot of our jobs are a short drive away. In the older blocks near Main Street and the historic districts, houses sit close together on narrow lots, the steps and walks have usually been patched more than once, and a truck can't always get close to the work. Farther out, the subdivisions have attached garages, wide driveways and backyard patios, and the busier roads are lined with rentals and small business lots that need their walks and parking kept in shape. We see much the same mix next door in St. Peters.

For our work, what ties the city together is the ground. Saint Charles sits along the Missouri River, and low yards that stay wet or lots built up with fill years ago tend to settle under a slab, so on most jobs here the digging and the base matter more than anything you'll see on top.

Services in Saint Charles, MO

  • Concrete driveway building

    Driveways on older lots here often sink at the edges or tip toward the garage. We build new concrete driveways on a packed base, sloped away from the house.

  • Concrete steps construction

    Front steps on older houses here often pull away from the house or crumble after years of freezing. We tear them out and rebuild them on footings set deep enough for frost.

  • Concrete sidewalk building

    Walks heaved by tree roots are common on older streets and rental properties. We replace the broken sections and cut control joints, grooves that give cracks a planned place to form.

  • Concrete patio construction

    Older patios here often pool water against the house because they were poured flat or tilted the wrong way. We check where the water runs and slope the new one away.

  • Concrete footings

    Decks, additions and porches here need footings that sit below where winter freezes the ground. We dig, form and pour them to the depth your plans call for.

  • Foundation raising

    Slabs on low, wet ground near the river can settle as the soil shifts. We find out why it sank before we raise it, since lifting it without fixing the cause rarely lasts.

Working in Saint Charles: permits, licenses and what sets the price

In Saint Charles, the city's Building Division issues construction permits, and when a job needs one, the pour waits until the permit is in hand, so we take care of it early. Before we start, we check with the office that covers your address, and if a permit is needed we handle the filing and keep you posted, including when another office has to sign off too. The city also requires a business license of anyone doing business here, even for a short job and even for contractors from out of town, so it's a fair question to ask any crew you're thinking of hiring. We're licensed and insured, and we're glad to answer it.

Price here comes down to a few things: how big and how thick the slab is, whether an old one has to be broken out and hauled away, how much digging and packing the base needs, and how close a truck can get. The finish matters too, because a broom finish, the light texture that gives shoes and tires some grip, costs less than stamped or colored work. The schedule turns on the weather, any permit, and curing, the days fresh concrete needs to harden before it can take weight, and your estimate shows how each of these plays out on your job. We work the same way across the river in Bridgeton and out in O'Fallon.

Saint Charles, MO properties and local conditions

Saint Charles winters are hard on concrete. The city's building code plans for severe weathering and a 30-inch frost line, which are design numbers for the area rather than a reading at your house, and they line up with what we see on jobs. Water soaks into the surface, freezes, and chips the top or pushes steps and walks out of line. So we set footings for steps, porches and additions at the depth the code calls for, lay rebar, steel bars that keep a slab from pulling apart if it cracks, where the slab needs the strength, and grade the ground so water runs off instead of sitting there to freeze.

A lot of the slabs we tear out here were poured on dirt that was raked level instead of dug out and packed, and on filled or wet ground that dirt settles and takes the concrete down with it. I spent years fixing exactly that on rental properties before I started this business. When a budget gets tight, people usually want to cut the base and keep the fancy finish. I'd do it the other way around, because a plain finish still looks clean, but a bad base can't be fixed without tearing the slab out.

  2. Walk the site with me

    I come out myself, look at the old slab, the ground and where the water runs, and ask how you'll use the concrete before I suggest anything. Afterward you get a written estimate with each part of the job listed separately, so you can see what you're paying for.

    When the work is done, I walk it with you and go over curing and when it's ready for feet and then cars. I'll also explain how to look after it through a Saint Charles winter.

Frequently asked questions

Do I need a permit to replace a concrete driveway in Saint Charles, MO?

Any part of the job that touches the public sidewalk or street needs a permit from the city's Engineering Department, and so does a dumpster, POD or crane parked in the street. What the rest of the job needs depends on your address and the work, so we check with the city before we start and file whatever is required.

Do I need historic district approval for new concrete steps in St. Charles?

If your house is in one of the city's six historic districts, you may, because the Landmarks Board has to approve exterior changes and new construction there, fences included. Some maintenance work doesn't need approval, and the city's planning staff at 636-949-3228 can tell you whether your project does. If it needs review, we build that into the schedule.

How do I find out if my house in Saint Charles is in the floodplain?

Ask a flood zone determination company, your insurance provider or a registered Missouri land surveyor, because the city says only they can tell you for certain. This matters most for a new slab foundation or an addition, since building in the floodplain takes a Floodplain Development Permit. On a new or substantially improved building, the permit requires the lowest floor, basement included, to sit at or above the 100-year flood elevation, certified by an engineer, architect or land surveyor registered with the state.

How much does a new concrete driveway cost in Saint Charles?

It comes down to the size and thickness of the driveway, whether the old one has to come out, how much base work your ground needs and the finish you pick, so I give you a price after I've seen the site. Tight access on older lots near Main Street can mean smaller equipment and more hand work, and work that reaches the sidewalk or street adds a permit. A broom finish is the plainest option, and stamped or colored concrete costs more.

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

You can usually walk on it after a day or so and drive on it after about a week, though cool fall and spring weather slows curing down. Concrete keeps gaining strength well after it looks dry, so parking on it early can crack an edge or leave marks you'll see for years. I'll give you the wait for your slab and that week's weather when we finish.

What causes concrete driveways to crack and sink in Saint Charles?

Most sinking starts with a base that wasn't dug out and packed, and most random cracking comes from control joints that were cut late or skipped. Freezing water chips the surface over the winters here, and a slab poured in midday summer heat can end up with a weak, dusty top. Concrete still cracks some, but with a packed base, good drainage and joints cut on time, the cracks usually stay in the joints where they belong.
