Two estimates can show different totals while describing very different projects. The useful comparison is not simply the number at the bottom; it is what each contractor has included, excluded and assumed.
Start with the same project information
Give each contractor the same plans, photos, finish expectations and known conditions. When bidders work from different information, the resulting prices are not directly comparable.
Compare scope line by line
Look for demolition, protection, disposal, framing, plumbing, electrical, waterproofing, drywall, finish work, cleanup and permit responsibilities. A lower estimate may simply leave work undefined.
Identify allowances
An allowance is a placeholder for an item that has not been selected. Record what each allowance covers, whether tax and delivery are included, and what happens if the final selection costs more or less.
Read exclusions and assumptions
Exclusions describe work the contractor is not pricing. Assumptions describe conditions the price relies on. Pay close attention to hidden damage, hazardous materials, utility upgrades, engineering and owner-supplied items.
Compare schedule and supervision
Ask who will manage the project, how often the site will be supervised, how schedule changes are communicated and whether the estimated duration depends on selections being completed by specific dates.
Evaluate change-order rules
Understand how added work is priced, who must approve it and whether overhead or administrative fees apply. Clear procedures protect both the homeowner and contractor.
Use a written comparison sheet
Create columns for each contractor and rows for scope, allowances, exclusions, schedule, payment terms, warranty, communication and licensing. Mark unknown items for follow-up before choosing.
ADELIE perspective
The best estimate is the one that makes the project understandable. A detailed scope may cost more on paper while creating fewer surprises during construction.
