Concrete tear-out pricing: the line item contractors forget to charge for

Ask a contractor what got left off the last quote they regret and a lot of them will say the same thing: tear-out. The replacement slab got priced carefully, the finish got priced, the thickness got priced, and the day and a half of breaking up and hauling away the old driveway got waved through as part of the job. Here is how to stop doing that.

Tear-out is a separate job

Removing an existing slab has almost nothing in common with pouring a new one. It has its own costs:

• Breaking. A jackhammer, a breaker on a skid steer, or a saw for clean edges. Time, fuel, and wear.
• Loading. Broken concrete is heavy and awkward. This is either machine time or a crew doing the least pleasant work of the week.
• Hauling. Trailer or dump truck trips, sized by weight rather than volume, because concrete gets heavy long before it fills the bed.
• Disposal. Landfill or recycler fees, charged by the ton. This is a hard cost with a receipt.
• The extra day. Demo usually means the pour cannot happen the same day, which stretches the job and pushes the next one.

None of that is included in a per square foot pour rate. If your quote treats it as though it is, you are donating a day.

What makes it more or less expensive

Not all tear-out is equal, and the variables are worth checking on site before you commit to a number:

• Thickness and reinforcement of the existing slab. A 4 inch unreinforced patio comes up in pieces. A 6 inch driveway with rebar in it fights back the whole way and takes far longer.
• Access. If the machine can drive to the slab and the trailer can back up to it, demo is fast. If everything has to be barrowed through a side gate, the cost can multiply. This is the same access problem that makes the pour harder, and it applies twice on a tear-out job.
• What is underneath and around. Sprinkler lines, gas or electrical runs to a garage, mature landscaping, and finished surfaces you have to protect all slow the work down.
• Disposal distance and tipping fees. These vary a lot by area and they are a real, checkable number in your market.

Pricing it

The clean approach is a per square foot adder on the same area you are pouring, because that is the area you are removing. It scales correctly and it is easy to explain.

In the CementQuote default price book, tear-out sits at 3.50 per square foot. On a 600 square foot driveway that is 2,100 dollars, which covers the machine time, the trips, and the tipping fees for a typical slab in normal conditions. Yours may be higher in an area with steep disposal costs, or where most of your work is behind fences.

Two things worth building into how you quote it:

1. Charge for reinforced demo separately, or price for the worst case. If the existing slab has rebar in it, your labor could double. Either ask on site and price accordingly, or set your standard rate high enough that reinforced slabs do not put you underwater.
2. Handle limited access explicitly. If a wheelbarrow is the only way in, that multiplies both the pour and the demo. A blanket access multiplier on the job, something like 15 percent, is a simple way to keep it honest.

Show it on the quote

Tear-out is one of the few line items that makes your price look better rather than worse, so hiding it is doubly foolish.

Consider two bids on the same driveway. Yours is 12,400 dollars. The other is 10,800 dollars. If your line item says "Driveway, 600 sqft: broom finish, 5 in, rebar, tear-out and haul away of existing slab included" and theirs says "600 sqft driveway, 10,800," the homeowner has a question to ask the other contractor. Frequently the answer is that removal was not in the number, and yours was the honest bid all along.

Left invisible, you simply look 1,600 dollars more expensive.

The estimate-day version of the problem

The real reason tear-out gets missed is not that contractors do not know it costs money. It is that quoting happens fast, often from a photo and a memory, hours after the site visit. Tear-out is the item most easily forgotten because it is not part of the thing being built.

The fix is structural rather than a matter of discipline. Make removal a switch that is always on screen, so leaving it out is a decision instead of an oversight. In CementQuote, tear-out is a checkbox on every pour, right next to color, sealer, and limited access. Tap it and the adder applies to that pour's square footage, the total updates, and the words "tear-out" print on the customer-facing line item.

You stop forgetting it, and the customer sees exactly what they are paying for.
