About St. Peters, MO
St. Peters sits between Saint Charles and O'Fallon, and most of what we see on jobs here is subdivision housing. That usually means ranches and two-stories with attached garages, a front walk, a few steps up to the porch and a patio out back, built in waves over the last few decades. Shops and offices line the bigger roads, so we get calls from small business owners and landlords too, but the bulk of the work is at people's homes.
Houses that went up around the same time tend to wear out around the same time, so one street can have several driveways sunk at the same corner by the garage. That usually traces back to how the ground was graded and packed when the house was built, which is why I look at what's under the old slab before I price the new one.
Services in St. Peters, MO
Concrete driveway building
Many driveways here sink near the garage, where loose fill settled after the house went up. We break out the old slab, dig to firm ground and pack a new base.
Concrete patio construction
Many older patios here tip toward the house and hold rain against the foundation. We slope the new one away from your walls and broom the top so it grips when wet.
Decorative concrete
Homeowners redoing a backyard here often want more than plain gray, and decorative concrete adds color, pattern or a border. We still build the base first, because a pattern won't save a sinking slab.
Concrete sidewalk building
Tree roots and frost lift front walk panels here until one edge catches a toe. We replace the broken sections and cut control joints, grooves that tell cracks where to run.
Concrete steps construction
Front steps here often settle at one end or pull away from the porch. We rebuild them on packed ground with rebar, the steel rod that holds the concrete together.
Garage floor concrete
Salt dripping off cars all winter pits and flakes older garage floors here. We break out the worn floor and pour a new slab sloped to drain toward the door.
What a concrete job in St. Peters involves before the first pour
Before we put a St. Peters job on the calendar, we check with the city. The City of St. Peters issues permits for work such as new construction, additions and remodels, and owners apply through the city's CitizenServe portal, where inspections get scheduled too. If your job needs a permit, we handle the filing and keep you posted, and we'll tell you if another office has to sign off as well, so a permit can add time to the front of the schedule. We're licensed and insured, and St. Peters businesses apply for their city license through that same portal.
Price here mostly comes down to size, how much old concrete we break out and haul away, how deep we dig to reach firm ground, how close a truck can get on a tight lot or past a backyard fence, and the finish you pick. If something has to give, I'd rather you take a plain finish over a well-packed base than a fancy surface over soft dirt, because nobody sees the base on day one and it's the part I spent years repairing for other people. After the permit check, weather and curing, the days the concrete needs to harden before you use it, set the schedule, and your written estimate shows each of these costs on its own line. We do the same work over in Chesterfield and across St. Charles County, and the ground work doesn't change from one city to the next.
St. Peters, MO properties and local conditions
The ground under a lot of St. Peters yards is clay, which swells when it's wet and shrinks when it dries, and the dirt pushed back in around a new house often wasn't packed hard. That's why we see so many slabs sunk at the house or the garage. We dig that soft fill out and pack the subgrade, the ground the slab sits on, in layers before anything is poured, and we check where your roof and yard send their water so it runs away from the new concrete.
Winters here swing above and below freezing, so water that gets into a crack freezes, pries it wider and lets salt in behind it. We start summer pours early so the top doesn't set too fast in the afternoon heat and turn dusty later, and we seal new slabs before their first hard winter.
Get a free on-site concrete estimate in St. Peters
We reply to calls and messages within one business day to set up a time for me to come out to your St. Peters property. I'll walk the site with you, explain your options and then send a written estimate, and there's no pressure to book.
What happens after you call us about a St. Peters job
Call or send the form
Tell us what you're seeing, whether it's a sunken driveway, a cracked patio or a walk that trips people. We'll set a time for me to come out, and a few photos help me come prepared.
I walk the site with you
I look at where the water runs, how the old slab failed and how you'll use the new one, then explain your options before I write anything up. Because the tear-out, the base and the finish are priced separately, you see what each part costs before you decide.
We check permits and pour
Once you say yes, we check what your address needs from the city or county and file any permit it calls for. Our crew lead runs the job from tear-out to finish, and you don't need to be home on pour day as long as we can reach the site.
Walk the finished job together
When it's done I walk the new concrete with you and go over how to care for it. You'll leave knowing when it's safe to walk on, when to park on it and what to keep off it the first winter.
Frequently asked questions
Do I need a permit to replace a concrete driveway in St. Peters, MO?
You might, and we find out before any work starts, because the city lists its permit work as examples and doesn't spell out every concrete job. We check with the city for your address, and if a permit is needed we file it and keep you posted so you're not left guessing.
Does selling my house in St. Peters need an occupancy inspection?
No, the city doesn't require an occupancy inspection when an owner-occupied home is sold, though building permits still apply to any work done at the house. Rentals are different, since the city requires a re-occupancy inspection each time a new tenant moves in. If you're a landlord, tell me when the next tenant arrives and we'll schedule the concrete around it.
How much does a new concrete driveway cost in St. Peters?
Your driveway's price is set mostly by its size and how much ground work it needs, and I won't give a number until I've seen it, because the dig and base under a settled driveway can't be judged from a photo. A thicker slab, rebar, a wider apron or a stamped border add to it, while a plain broom finish keeps it down.
How long does new concrete need to cure before I can drive on it?
You can walk on new concrete well before you can drive on it, and I give you both dates for your pour, since the mix and that week's weather change them. Parking on it too soon is one of the easiest ways to crack a brand-new driveway, so the wait is worth it.
Will a new concrete driveway in St. Peters crack like my old one?
A new slab can still get hairline cracks, but a well-built one cracks along the joints we planned and stays level, which is a different thing from the broken, sunken slab you have now. That comes from the packed base, control joints cut the day of the pour and rebar inside, and I don't skimp on any of them.
How do I protect a new concrete driveway through a Missouri winter?
Keep deicing salt off it the first winter and shovel instead, because fresh concrete is most open to salt and freeze damage early on. After that, resealing every few years and keeping downspouts aimed away from the slab do most of the work.
