A masonry quote is a description of work with a price attached to it. When two quotes for the same wall differ by thousands, the usual explanation is not that one contractor is greedy and the other generous. It is that they are describing two different jobs, and the description is buried in lines that read as boilerplate.
A quote is a scope, priced
A complete estimate identifies the work area and its dimensions, the demolition and disposal involved, the preparation and base work, the materials by specification rather than category, the labor, the equipment and access, the cleanup, and the terms covering payment and warranty. A single-line quote for a wall with a number after it is not a cheap quote, it is an undefined one, and every ambiguity in it will be resolved in the contractor’s favour later because nothing written says otherwise.
Where the labor number comes from
Labor is usually the largest share of a masonry job, frequently more than half. That surprises people looking at the price of block or brick and doing arithmetic. What they are not pricing is the unproductive time: setting up and striking scaffold, mixing, hauling material to the work face by hand because the truck cannot get close, cutting units, and cleaning down at the end of each day. A crew rate multiplied by realistic days is what most of the number is, and a bid that is far below the others has usually shortened the days rather than found a cheaper mason.
Material lines that hide the specification
The material lines are where the important omissions live. Mortar described only as mortar tells you nothing: type S and type N behave differently, and on older brick a lime-based mix is the correct answer and a cement-rich one causes damage. Aggregate base described without a depth is not a specification. Reinforcement, geogrid, drainage pipe, filter fabric, ties, flashing, and weeps are all items that a bid can quietly leave out, and all of them are invisible once the work is finished. When a quote lists a proprietary product by name and depth, that is a good sign about the contractor.
Access, disposal, and the costs nobody photographs
Demolition and haulage are real money on a masonry job, because the debris is dense and dump fees are charged by weight. Access is the other one: a wall reached only through a house, a narrow alley, or a back garden with steps changes the labor number substantially, and a contractor who has not walked the site has not priced it. Permit fees, protection of adjacent surfaces, and making good the landscaping afterwards belong in the quote too, and their absence is a conversation worth having before signing rather than after. Two more lines deserve a look for the same reason. Water and power on site sounds trivial until a contractor has to bring both, and unforeseen ground conditions need a stated mechanism, whether an hourly rate or an agreed process, because discovering rock or a buried drain halfway through is common enough that silence on it is not an oversight.
Comparing two bids that describe different jobs
Line them up item by item rather than comparing totals. Where one bid is lower, find which line accounts for the difference: it is nearly always base depth, drainage, or reinforcement. Then ask both contractors the same question about that line and see who is more specific. A payment schedule tied to milestones rather than a large deposit up front, a written warranty on workmanship, and evidence of current insurance are the other three things worth confirming before price enters the conversation at all.
Frequently asked questions
How much deposit is normal? Enough to cover material ordering, commonly a modest percentage, with the balance tied to progress milestones and a final payment on completion. A demand for most of the money before work starts is worth questioning.
Should quotes be itemized? Yes, and a contractor who declines to itemize is telling you something. Itemization is what makes two bids comparable and what stops a dispute later about whether something was included.
Why do quotes for the same wall vary so much? Usually scope. One bid includes excavation to a proper depth, drainage, and reinforcement, and another builds a facing on shallow fill. They look like the same wall on the day it is finished, and they behave very differently after five winters.
