Three Contractor Bids, Three Different Prices: How to Compare Them

1. Give every contractor the same job to price

Start with one written scope: the rooms involved, what stays, what goes, what gets replaced and the finished result you expect. Attach the same plans, measurements, photos and product selections to each request. Identify who supplied measurements and who must verify them before ordering. If contractors visited at different stages of your planning, send an updated scope to everyone rather than assuming they remember the changes.

Ask each contractor to return a revised proposal tied to that scope and dated version. Request separate prices for optional upgrades so a nicer countertop does not obscure the cost of the basic job. You do not need every fastener itemized, but major work categories should be recognizable. When a contractor proposes a different method, ask what changes in performance, maintenance, schedule and price. A legitimate alternative deserves its own comparison, not an invisible substitution.

• List demolition, preparation, installation, finishing and restoration as distinct tasks.
• Identify items you will supply and who receives, stores and installs them.
• Separate must-have work from alternates that can be accepted or declined.
• Require written identification of deviations from your requested scope.
• Specify occupied-home needs, including usable bathrooms and end-of-day access.

2. Build a side-by-side sheet before comparing totals

Copy each proposal into a simple comparison sheet. Use one row per major component and mark it included, excluded, allowance or unclear. Do not treat a blank as included. Keep the original quoted total visible, then track additions needed to reach your common scope. This preserves the difference between what a contractor actually offered and what you estimate the completed project might cost.

The table below illustrates the method, not market pricing. Bid A looks cheapest, but its omissions prevent a fair comparison. Ask that contractor for written prices for the missing work and ask Bid C what its disposal allowance covers. If you temporarily insert your own estimate, label it unconfirmed. Do not rank an estimate as though it were a binding offer.

Once each contractor responds, calculate a comparable total using confirmed additions and credits, without counting existing allowances twice. Keep unresolved risks beside the number, not buried in notes. A bid with a known price for difficult preparation can be more useful than a lower total that postpones the same cost until demolition. Ask whether additions also change the completion date.

3. Match specifications, not just product descriptions

Words such as “premium,” “standard” and “contractor grade” are not specifications. Match manufacturer, product line, model, dimensions, finish and quantity wherever possible. For cabinets, compare box construction, door material, hardware and installation details. For flooring, compare product thickness, wear layer where applicable, underlayment and substrate preparation. Similar-looking finishes can have different installation requirements and warranties.

Compare the work underneath, too. Tile pricing should identify the waterproofing approach where needed, surface preparation and transitions. Painting should state which surfaces receive preparation, primer and finish coats. Ask whether the installation follows the selected manufacturer's instructions and who resolves conflicts with the plans. Products ordered online or supplied by you still need a clear responsibility chain if they arrive damaged, incomplete or unsuitable.

For a 2026 project, require a current availability check rather than relying on a showroom conversation from months ago. Ask how long the material quote remains valid, whether freight and applicable sales tax are included, and what happens if a selection becomes unavailable. Any substitution should require your written approval, with its price and schedule effects disclosed before ordering. Confirm who pays restocking or return charges if an approved selection later changes.

4. Turn allowances into realistic purchasing budgets

An allowance is a placeholder for a cost not fully determined when the proposal is written. It is not automatically a cap on what you will pay. A $2,000 fixture allowance may cover purchases only, while another contractor's allowance may include delivery and installation. Ask what each allowance includes and how the final charge or credit will be calculated.

Price your likely selections before signing. If you expect to buy $3,500 in fixtures, a $2,000 purchase allowance leaves a $1,500 gap before any applicable tax, delivery or contractual markup not already included. Use the same realistic selection budget across all bids, but adjust only the difference from each existing allowance. Do not add the entire purchase cost again.

• Does the allowance cover materials alone, or installation labor as well?
• Are tax, freight, delivery, waste and accessories inside the stated amount?
• Is contractor markup included, and does it apply to overruns?
• Will invoices support the reconciliation, and will underspending produce a credit?
• When must selections be finalized to avoid delaying the job?

5. Identify every trade, permit and inspection responsibility

A general contractor's proposal should explain which trades are included and who coordinates them. Hiring subcontractors is common; the issue is whether their work is covered by the quoted price and managed under your contract. If you must hire the electrician separately, that expense and coordination belong in your comparison. Ask who handles scheduling conflicts and repairs damage caused by one trade to another's completed work.

Permit and inspection requirements vary by location and project. Check with the local building department rather than accepting a blanket claim that a remodel needs no permit. Distinguish permit application work, fees, required drawings and inspection scheduling. A proposal that includes “permits” may not include engineering or utility-related charges.

• Are plumbing, electrical, HVAC and specialty subcontractors included in this total?
• Who contracts with and pays them, and who supervises their work?
• Who obtains permits, and in whose name will they be issued?
• Are required plans, plan-review fees and inspection fees included?
• Who attends inspections and pays for corrections or repeat inspections?
• What documentation will show required approvals and permit closeout?

6. Read exclusions as a second scope of work

Exclusions tell you where the quoted price stops. Some are reasonable because hidden conditions cannot be measured before walls are opened. Others remove predictable tasks, such as patching around new wiring or repainting disturbed surfaces. Ask contractors to distinguish genuinely unknown conditions from work that is already foreseeable. “By owner” means you need to budget money, time or both.

Cleanup deserves its own definition. Daily sweeping is not the same as debris hauling, disposal fees or final cleaning. Ask about dust barriers, protection of floors and landscaping, dumpster placement and removal, and who repairs damage along the access route. Confirm whether old appliances, leftover materials and hazardous waste are included or require separate arrangements.

For concealed damage, request a written discovery process: photographs, an explanation of necessary work, a price and your authorization before proceeding, except for clearly defined emergency measures. Where practical, agree on unit prices for uncertain quantities, such as replacing additional damaged subfloor. Those prices still need defined materials and labor. If lead paint, asbestos or another hazard is suspected, verify applicable testing and handling requirements before disturbance; ordinary demolition pricing may not cover specialized work.

7. Choose the contract you can understand and manage

After normalizing the work, compare the business terms. Is the price fixed for the defined scope, an estimate, or cost-plus? When does it expire? What permits an increase? Read deposit and progress-payment terms, start assumptions, anticipated duration and warranty coverage. Verify required licensing and appropriate insurance independently, and check references for projects similar to yours. A polished spreadsheet cannot replace those checks.

Make sure clarifications become part of the signed agreement, with referenced plans, specifications, allowances and exclusions attached. Establish which document controls if descriptions conflict. Require written change orders showing added or credited cost and schedule effects. Keep your own contingency separate from the contract price; it is your reserve, not permission for unapproved spending.

Finally, ask each finalist: “What necessary work could still cost me more, and what have you assumed I will provide?” The strongest answer is specific and documented. Choose based on the comparable price, remaining uncertainty and demonstrated ability to deliver—not simply the smallest number on page one. If a contractor will not clarify material gaps, you do not yet have a bid you can confidently accept.
