Planning and pricing terms homeowners actually see
These are the words that tend to cause confusion when quotes are compared side by side. The definitions below are intentionally practical: what the term means, what it does not mean, and what to ask when it appears in a proposal.
Allowance
A placeholder amount for an item that has not been fully selected or defined. If a vanity allowance is $1,200 and the final vanity costs $1,650, the contract may increase by the difference plus any related labor or markup allowed by the agreement.
Ask: What exactly does the allowance cover—material only, tax, delivery and installation too?
Bid / proposal
A contractor's written offer to perform a defined scope for stated compensation and terms. A low total is not automatically a better bid if demolition, permits, cleanup or finish work are missing.
Ask: What is specifically excluded?
Change order
A written change to scope, price or schedule after the original agreement. Good change orders explain what changed, why it changed and what the added or reduced price is before the work proceeds.
Contingency
Money reserved for uncertainty, such as concealed damage or conditions that cannot be confirmed before demolition. It is different from an allowance: an allowance is for a known item with an undecided selection; contingency is for unknown conditions.
Cost per square foot
Total cost divided by a stated area. The phrase is only useful if the denominator is clear. Living area, roof surface, wall area and finished floor area are not interchangeable.
Ask: “Per square foot of what?”
Estimate
A forecast based on current information and assumptions. It may change when measurements, selections or site conditions become clearer. An online estimate is useful for budgeting, but it is not a binding contractor quote.
Labor burden
Employer costs above base wages, which can include payroll taxes, workers' compensation, insurance and benefits. A contractor's labor rate may also include supervision and overhead.
Material takeoff
A quantified material list built from plans or field measurements. A takeoff might include roofing squares, concrete yards, drywall sheets or linear feet of trim.
Mobilization
The cost of getting labor, tools, equipment and protection measures to the job and setting up the site. Small jobs can carry a relatively high mobilization cost because setup is required regardless of project size.
Overhead and profit
Business costs and earnings that are separate from direct labor and material. Office staff, estimating, vehicles, insurance, software, supervision and warranty risk can all sit behind contractor overhead.
Permit allowance
A placeholder for permit and inspection costs when the exact amount has not yet been confirmed. It should state whether the contractor's administrative time is included.
Punch list
A list of incomplete or corrective items identified near the end of the project. The contract should make clear how punch-list items are documented and completed before final payment.
Roofing square
A roofing quantity equal to 100 square feet of roof surface. It is not the same as 100 square feet of house floor area.
Scope of work
The written description of what is included, the materials or standards being used, who is responsible for each task and what is excluded. Scope is the backbone of a useful contractor comparison.
Unit price
A price tied to a measurable unit, such as per sheet of roof decking, per cubic yard of concrete or per linear foot of trim. Unit prices are useful for concealed work because they establish a method before the quantity is known.
Waste allowance / waste factor
Extra material added for cuts, breakage, pattern matching or unusable pieces. It should reflect the product and layout, not a universal percentage applied to every job.
Warranty: manufacturer vs workmanship
A manufacturer warranty generally addresses the product under its terms. A workmanship warranty addresses installation performed by the contractor. They are not the same document and may have different durations, exclusions and claim procedures.
Three terms people often mix up
| Term | What it covers | Example |
|---|---|---|
| Allowance | Known item, selection not final | $4,000 cabinet hardware allowance |
| Contingency | Unknown condition | Reserve for concealed deck damage |
| Unit price | Known rate, quantity not final | $95 per sheet of roof decking replaced |

When a contractor uses one of these terms, copy the exact wording into your notes and ask what is included. Then use the Contractor Quote Comparison and Project Contingency Calculator to keep the numbers organized.
