Question 1

How accurate is a concrete cost calculator?

Accepted Answer

A good calculator gets you within roughly 15 to 20 percent on a typical residential project because square footage, thickness, finish and site conditions drive most of the cost. What it cannot see is access, existing slab condition, subgrade quality, drainage problems and permit requirements, which is why an on-site measurement is still required for a firm price.

Question 2

How do I measure my driveway or patio for an estimate?

Accepted Answer

Multiply the longest length by the widest width in feet to get square feet, and round up. For L-shaped areas, break the space into rectangles and add them together. A standard single-car driveway is roughly 12 x 25 feet and a two-car driveway about 24 x 30 feet.

Question 3

What adds the most cost to a concrete project?

Accepted Answer

In order: demolition and haul-off of existing concrete, poor subgrade requiring extra base import and compaction, decorative finishes such as stamping and coloring, added thickness and rebar for heavy vehicles, and restricted access that requires a concrete pump instead of chuting straight off the truck.

Question 4

Is there a minimum project size?

Accepted Answer

Yes. Mobilizing a crew, truck and materials carries a fixed cost, so very small pours are priced at a minimum rather than by square foot. Small projects also cost more per square foot than large ones for the same reason.

Question 5

Does the calculator include permits?

Accepted Answer

No. Permit and any engineering or survey fees vary by jurisdiction and project type, so they are quoted separately after we confirm which building department has your parcel.
