Keep the old footings or pour new ones?
The answer is usually in the ground, so we look at how deep the old footings go, what shape the concrete is in and whether you're adding weight.
Keeping them works when:
- They're deep enough already
- The concrete is solid, not crumbling
- Posts and beams still sit level
- You're keeping the same structure
- No new weight is going on
New footings make sense when:
- You're adding a deck or a room
- Old footings are shallow or cracked
- The structure has shifted or sunk
- Posts sit on blocks or bare dirt
- New plans carry a bigger load
- Water keeps pooling at the base

A visit scheduled
I look and measure
I come out to look at the site, measure and walk you through your choices, and we settle the depth with you and your plans before anyone digs.
Depth agreed on
Written estimate and plan
You get a written estimate that says what's included and what isn't, plus a plan that lays out each step of the job in order.
A written estimate
Inspections, digging and pouring
We line up any inspections, and in O'Fallon they're usually done the day after they're scheduled. Then our crew digs, forms and pours the footings.

Walk-through and clean-up
Once the pour is done, I walk the finished job with you, go over how to care for it and make sure the site is cleaned up.
A clean site
What our concrete footing work includes
Layout from your plans
We mark each footing where your plans put it, so posts and walls land square on top.
Digging to the agreed depth
Our crew digs each hole or trench to the depth we settled on, down to firm soil.
Cutting through old concrete
If a patio or slab is in the way, concrete cutting opens a clean hole without tearing out the whole slab.
Forms and rebar
We set forms where needed and place rebar, steel that helps the concrete carry load, when the plans call for it.
The pour
We pour into clean holes and work the concrete down so it fills each form without gaps.
Curing
We keep the fresh concrete from drying out and help hold it at a good temperature while it cures and gains strength.
Clean-up
We haul off the extra dirt and leftover material and leave the work area tidy.
What changes the price of concrete footings?
The count and size come first: how many footings your plans call for, how deep each hole goes and how wide it has to be. Access matters almost as much, because a row of deck footings in an open yard digs easily, while a trench tucked against the house often gets dug by hand.
Then there's what the site hands us. Old concrete that has to be cut out, wet clay that needs a plan for water, or a winter start that waits on frost-free ground can add work or push the date. Your written estimate spells out what's included and what isn't, like hauling away dirt and old concrete, so you know what you're paying for before anything gets dug.
Why O'Fallon homeowners call us for footings
I spent years building schedules for a busy company before I learned concrete on a crew, and I started this business in O'Fallon in 2017. I still think like a scheduler, so every footing job gets laid out in order before we dig: the depth, any inspection, the pour and the wait before anyone builds on it.
If there's one place I won't trim to save you money, it's the depth of the hole. Nobody sees it once the deck or wall goes on top, but it's what decides whether frost can get under it. Call (636) 614-2331 with your plans and questions, and I'll walk you through them.

Do I need a permit for concrete footings in O'Fallon, MO?
Ask before anyone digs, because footings usually go with a project the city permits, like a deck, room addition or new home. O'Fallon's Building Division handles permits for new homes, decks, sheds, garages, room additions and structural changes, and its list names those projects, not footings on their own. Several independent fire districts also serve O'Fallon, separate from the city, and they may require their own building permit. We check with the offices that cover your address before we schedule, and when a permit's needed, we handle the paperwork and line up the inspections.
How deep do footings need to be in O'Fallon, MO?
They go below the frost line, and St. Charles County's code fills in that depth as 30, the minimum depth of a footing below finish grade, which is the finished ground surface. Setting them that deep keeps freezing, expanding soil from heaving them up. We settle the exact depth with you and your plans before anyone digs.
Can concrete footings be poured in winter?
Yes, once the ground is clear of frost. The residential concrete standard calls for the forms, the steel, the concrete materials and any ground the concrete touches to be free of ice, snow and frost, so a cold stretch can move your start date. On a winter job, we leave room on the calendar to wait for clear ground instead of pouring into a frozen hole.
What do concrete footings cost in the St. Louis area?
Footings are priced by the job, and for a local reference, slab foundation work in St. Louis usually costs about $4.50 to $9.50 per square foot installed. That's the going rate for slabs, not a price for your footings, which comes down to the count, depth and access covered above. Your written estimate gives your price, with what's included and what isn't.
What causes concrete footings to shift in St. Charles County?
Usually it's the ground, either frost lifting a footing that sits too shallow or clay swelling and shrinking with the wet and dry seasons. Across St. Charles County, 41% of the soil area is high shrink-swell clay, so it's common on lots around here. When your lot has it, we talk with you about keeping water away from the footings, since water is what makes clay move.
How do I know if my old deck footings need to be replaced?
Posts that have lifted, sunk or leaned, and concrete that's cracked or crumbling, are the usual signs. Footings that turn out shallow once we dig beside them usually need replacing before you rebuild. If the house itself has settled, foundation raising may be the job instead, and I can tell you which when I come out.
