Cost
Why Small Pours Cost More Per Foot
Every cost guide gives you a rate per square foot, including ours. Below a certain size that rate stops describing reality, and it is worth understanding why before you conclude somebody is overcharging.
This is the most common awkward conversation in concrete repair. Somebody has read that flatwork costs a certain amount per square foot, worked out the area of the one panel they need doing, and arrived at a number that bears no relationship to the quote in front of them. The quote is usually right and the arithmetic is usually wrong, and the reason is worth setting out plainly rather than leaving people to assume the worst.
What a per-foot rate is actually averaging
A published rate is derived from ordinary jobs of ordinary size. Inside it are two very different kinds of cost, blended together into one figure.
Some costs genuinely scale with area. Concrete volume, base material, the time spent placing and finishing. Double the area and these roughly double.
The rest do not scale at all. They happen once, at the same size, whatever the job. On a large pour they disappear into the total. On a small one they are the total.
The costs that do not get smaller
- Getting there. Travel, loading the vehicle, unloading, and doing it again at the end. Identical for a single panel and a full driveway.
- Setting up. Protecting what is nearby, getting the saw out, running power or water, establishing levels. A half-day of a crew's attention either way.
- Breaking out and hauling. Smaller, but not proportionally. A skip or a vehicle still has to arrive and leave whether it goes back full or half full.
- The delivery. This is the one that surprises people. Ready-mixed concrete comes with a minimum, and a small pour frequently pays for more material than it uses, or pays a charge for the privilege of ordering less.
- The day. A crew committed to your morning is not available for anything else that morning, and small jobs rarely combine neatly into one.
Add those up and you can see the shape of the problem. A small job is mostly fixed cost wearing a variable-cost label.
The bit that genuinely does get harder
Small work is also more exacting, which people find counter-intuitive.
A new panel has to meet existing concrete on several sides, at the right level, with the joints lining up. There is no room to absorb a discrepancy the way there is across an open area. Cuts have to be straight because every edge is visible against something already there.
And the finish has to be worked to blend with a surface that has weathered for years, knowing it will not match at first regardless. That is fiddly, slow work compared with running a broom across an open slab.
What to do about it
Group the work. Easily the most effective lever available to you. Three small jobs done on one visit share one set of fixed costs. If a panel needs replacing and the step round the side is also going, and the walk has a lip in it, price them together rather than individually.
Ask about scheduling. Some crews will fit a small job around a larger one nearby, which can be noticeably cheaper. That depends entirely on what else is running and it costs nothing to ask.
Be realistic about timing. A small repair may sensibly wait until it can be grouped, which can mean a date further out than you would like. That is the trade that keeps small work worth doing at all.
Do not defer a hazard. The exception to all of the above. A lip somebody can catch a foot on, or a panel letting water straight into the base, is not a good candidate for waiting, because the second problem is more expensive than the saving.
Why the quote can also be lower than you expect
It cuts the other way occasionally and it is worth knowing when, because it is the one situation where a small job is genuinely cheap.
If a crew is already working nearby, or already has a delivery arriving for another job that morning, most of the fixed costs on this page have already been paid by somebody else. Adding a panel to that day costs a fraction of what the same panel costs on its own.
You cannot engineer that situation, and you can ask about it. A contractor who works your area regularly will know whether anything is running nearby, and being flexible about the date is what converts that knowledge into a lower number. Insisting on a specific week removes the only lever that makes small work inexpensive.
Reading a high quote correctly
Worth knowing: some quotes on small jobs are priced to be refused. A contractor with a diary full of larger work may not want a half-day panel replacement, and rather than decline they quote a number that makes it worthwhile if you accept.
That is not dishonest, but it does mean a single high quote on small work tells you more about that contractor's week than about the job. Getting a second opinion on small work is worth more than it is on large work, precisely because the spread is wider.
Where the work is a failed panel or two against sound concrete, concrete repair is the page for it. Where enough panels have gone that the arithmetic tips the other way, repair or replace a concrete driveway covers where that threshold sits, and what resurfacing costs covers the overlay route, which has its own minimum-charge effect for the same reasons described here.
