Footings are the one concrete job where the consequences of getting it wrong compound. An out-of-level or undersized footing shows up later as a door that will not close, a crack running up drywall, and a repair bill many times the cost of doing it properly the first time.
| What changes | Effect on your price |
|---|---|
| Linear feet of footing | Footings are priced by the linear foot. A 24 by 24 detached garage needs about 96 linear feet around 576 square feet of slab. |
| Footing depth and width | Both are set by the load above and the soil below, and in Forsyth County the footing goes below the frost line. |
| Slab square footage | If the job is a monolithic slab or a footing-and-slab, you are paying for both measures at once. |
| Soil conditions | Rock costs more to dig. Soft or wet soil means going deeper or wider to find bearing. Neither is knowable until someone digs. |
| Inspections | Footings are inspected before concrete is placed. That is a scheduling cost as much as a fee, and it is why nobody honest pours the same day they dig. |
| Reinforcement, wire or fiber | Adds roughly 10 to 15 percent over a plain pour. Worth it anywhere a vehicle or a heavy load will sit. |
| Anchor bolts, straps and embeds | Whatever the structure above needs has to be set while the concrete is wet. Small cost, and impossible to retrofit properly. |
| Concrete truck access | Tight lots, long wheelbarrow runs and pump trucks all add labour to the exact same square footage. |
Call or text with the rough size and what is there now. A photo of the space answers half the questions before anyone drives out.
Someone walks the job, measures it, checks access and drainage, and leaves you a written number. Free, and there is no pressure attached to it.
Once you approve the price the work gets scheduled around the weather window. You get a start date and a realistic finish date, not a vague week.
Three specifications carry a foundation, and none of them are visible once the job is finished.
Footing width and depth follow the load above and the bearing capacity of the soil below, which is why they are specified rather than chosen. Reinforcement schedule follows the same logic. On any engineered plan these numbers come from the plan, and on anything permitted they get inspected. This is not an area with a cheaper option that is also a real option.
Damp proofing and waterproofing are not the same product or the same protection, and the right one depends on the water table, the soil and whether the space behind the wall is habitable. What is common to both is the drainage: a footing drain in clean gravel, daylighted or pumped, doing the actual work of keeping hydrostatic pressure off the wall. Piedmont clay holds water, which makes drainage the detail that matters most here.
These are three different structures with three different costs, schedules and inspection paths, and the choice is usually driven by the site's grade and water table rather than by preference. A sloped lot may make a walkout basement nearly free relative to the alternative, and a high water table may make one a bad idea at any price.
Residential and commercial foundations differ less in method than in how much of the design is prescribed before anyone digs.
Residential footings and foundation walls generally follow prescriptive code tables, with an engineer brought in for unusual spans, poor soils or retaining conditions. Inspections are still mandatory, and the sequence above is the sequence regardless of house size.
Commercial foundations are engineered from the start. Footing sizes, rebar schedules and any special inspection requirements come off stamped drawings, and there is typically more coordination with other trades for embeds, sleeves and underslab utilities. The practical consequence is that the schedule is set by the inspection and engineering calendar rather than by concrete cure times.
Foundations are the one category where the schedule is not set by the crew. Inspection hold points are, and they are non negotiable. Concrete cannot be placed until the inspector has passed what is underneath it, and building around those dates is most of the job.
Corners get set and squared off the approved plan. An error here is measured in the whole structure, so this step gets checked and rechecked before anything is dug.
Trenches are cut to depth and width. Footings have to bear on undisturbed, competent soil below the local frost line. Whether the soil at depth is actually competent is a question the excavation answers, and it is one of the few things that genuinely changes a foundation price mid job.
Forms set, steel placed and tied to the specified size and spacing, held off the earth on chairs so the concrete surrounds it. Anything embedded, such as anchors or a drain tie in, is set now.
Footings are inspected before any concrete is placed. Nothing pours until that passes. This date belongs to the inspection schedule, not to the crew, and it is the most common reason a foundation timeline moves.
Concrete placed and consolidated. Footings are usually poured separately from walls.
Wall forms set, steel placed, second inspection where required, then the wall pour.
Forms come off, the exterior gets damp proofed or waterproofed to spec, and the footing drain and gravel go in. This is the layer that decides whether the space behind the wall stays dry for thirty years.
Backfill waits until the wall has gained enough strength and, where required, until it is braced or the floor system is on. Backfilling a green wall is how walls crack, and it is not a corner worth cutting to save a day.
Foundation work is weather exposed at the worst possible moment, because an open trench collects water and a saturated trench bottom is not something you pour on. Rain in the middle of an excavation usually costs a day of pumping and recutting rather than just a delayed pour.

Most jobs touch more than one of these. If you are already pricing foundations & footings, it is usually worth pricing anything else you have been putting off in the same visit, because the mobilisation is already paid for.
