What to write on a concrete contractor estimate
A concrete estimate should state the area, thickness, reinforcement, concrete strength, finish, removal of the old slab and truck access requirements.
Materials and products are $3,501.00 of this $9,563.00 estimate (37%), so say how long those prices hold: supplier prices can move before the job starts.
Prices flatwork per square foot by thickness and finish, with ready-mix billed by the cubic yard and supplier short-load charges passed through.
Assumptions behind each line
Write these next to the 9 lines so the customer sees what the $9,563.00 depends on.
- Break out and remove existing driveway: 800 sq ft at $2.25 per sq ft ($1,800.00); extra sq ft at the same rate.
- Grade and compact 4 in gravel base: 800 sq ft at $1.10 per sq ft ($880.00); extra sq ft at the same rate.
- Crushed gravel base: 12 ton at $38.00 ($456.00); another grade or brand changes this line.
- Forms and wire mesh reinforcement: 800 sq ft at $1.40 ($1,120.00); another grade or brand changes this line.
- Ready-mix concrete, 4000 psi: 11 cu yd at $175.00 ($1,925.00); another grade or brand changes this line.
- Place, finish and broom texture: 800 sq ft at $3.10 per sq ft ($2,480.00); extra sq ft at the same rate.
- Saw-cut control joints and apply cure-and-seal: 800 sq ft at $0.45 per sq ft ($360.00); extra sq ft at the same rate.
- Concrete disposal fee: a flat $392.00.
- Driveway apron permit: a flat $150.00.
Changes, overruns and change orders
If the customer adds work, put it on a signed change order first. Pricing the extra in sq ft keeps it comparable with the $9,563.00 you estimated.
A 10% rise in material prices would add $350.10 to this job, which is why many concrete contractors limit how long an estimate stays valid.
Tips from concrete work billing
- Copy the batch ticket number, mix strength and yards delivered onto the invoice, because that is your proof of what went into the slab if cracking or strength is ever questioned.
- Explain next to the joint line that control joints exist to direct cracking and that hairline cracks are normal, so a crack in week three does not become a payment dispute.
- Pass through short-load and truck waiting charges from the ready-mix supplier at cost, with the supplier ticket attached, rather than swallowing them.
- If a pour was rescheduled for rain or freezing temperatures, note the new date and bill any re-mobilization fee the contract allows.

Frequently asked questions
How do I write a concrete contractor estimate?
Describe the job (Replace a 20x40 ft driveway with a four-inch reinforced slab and broom finish), list each line with an estimated quantity and rate, total it ($9,563.00 in the sample), state how long it is valid and what it assumes, then send it as a PDF for approval.
Is a concrete contractor estimate binding?
An estimate is a forecast, not a fixed price, so the final invoice can differ when the work or materials change. Rules vary by country and state; to stay safe, get written approval before billing noticeably more than the $9,563.00 you estimated.
How long should a concrete contractor estimate be valid?
Thirty days is common and is what this template uses. With 37% of the price in materials, a shorter validity protects you if supplier prices rise.
