Bricks and pavers are the worst thing to bin and the best thing to sell, for the same reason: weight.
Skips are priced by size and very often surcharged by weight, and there is nothing heavier per cubic metre than masonry. A part pallet of pavers can eat a meaningful chunk of a bin's allowance while costing you the tip fee on top of what you already paid for them.
Meanwhile there's someone two suburbs over pricing the same pavers new and wincing.
Why they sell so well second-hand
Three reasons, and they compound.
Freight is the killer on masonry. A pallet delivered costs real money in cartage, so buying local and collecting yourself saves a buyer a lot. That makes your driveway a genuinely attractive option.
Matching is a nightmare. Anyone extending a paved area, patching a path or repairing a garden wall needs bricks or pavers that match what's already there. Ranges get discontinued constantly. If yours match something common, someone is specifically hunting for them.
Small quantities are hard to buy new. Merchants deal in pallets. A person who needs forty pavers for a shed base can't easily buy forty, so a part pallet is exactly what they want.
What they're worth
Second-hand masonry generally sits well below new, and how far below depends mostly on quantity and how clean they are. There's no single number worth quoting because clay pavers, concrete pavers, commons and face bricks all behave differently, and the market varies by city.
The honest guide is this: price it so that collecting from you clearly beats buying new plus delivery, and it'll go. Try to get close to retail and it'll sit.
Things that lift the price: full or near-full pallets, still strapped and wrapped, clean and mortar-free, and a recognisable current range. Things that drop it: mortar still attached, mixed batches, heavy efflorescence, or a count you're guessing at.
Count them, honestly
The single most useful thing you can do is give a real number.
Buyers are working to an area. If they know they need three hundred pavers and your listing says "about a pallet", they can't commit. If it says two hundred and forty, they know immediately whether it works.
Count them properly, or count one layer and multiply by the number of layers, and say which you did. Note the size in millimetres and the colour or range name if you know it. A photo of the pallet label does more work than three paragraphs of description.
Recovered bricks are a different job
If you're pulling apart old brickwork rather than clearing surplus, the value depends almost entirely on whether the mortar comes off cleanly. Old lime-mortared bricks often clean up beautifully and are genuinely sought after for character work. Modern cement-mortared bricks usually don't, and the cleaning time rarely justifies the return.
Be straight in the listing about whether they're cleaned or still have mortar on them. Selling "cleaned" bricks that need cleaning is how you end up with someone unloading them back onto your driveway.
Where to list them
I built Overrun for exactly this. It's an Australian marketplace where only building materials are listed, so the people browsing are landscapers, bricklayers, builders and renovators who need what you've got. You list in under a minute from your phone, the buyer collects, and they pay you directly. We never take a cut of the sale.
Masonry is the category where this makes the most obvious sense. It's heavy enough to be expensive to throw away, valuable enough to be worth money, and local enough that the buyer will happily drive to you.
One thing worth remembering
Pavers and bricks don't deteriorate sitting on a pallet. Unlike timber or plasterboard, there's no rush caused by weathering.. a pallet in the side yard is the same pallet in six months.
That's a double-edged thing. It means you haven't lost anything by not getting to it yet. It also means they'll sit there indefinitely unless you decide to move them, and the usual trigger for that decision is moving house, when everything goes in a skip at once.
Better to list them while you can still find the pallet label.
Quick answers
Are second-hand bricks and pavers worth selling? Yes. Masonry is heavy, so it's expensive to bin and expensive to freight, which makes local second-hand stock genuinely attractive to buyers. Full or near-full pallets in clean condition sell best.
How do I price leftover pavers? Price it so collecting from you clearly beats buying new plus delivery. Quantity, cleanliness and whether the range is still current make more difference than age.
Are bricks with mortar on them worth anything? Less, and sometimes not enough to bother. Old lime mortar often cleans off well and those bricks are sought after for character work. Modern cement mortar usually doesn't, so be upfront in the listing about which you have.
