Compare remodel bids
Do not choose the low bid until the quotes line up.
If two contractor bids are thousands of dollars apart, they may not be pricing the same project. Bid Before Build gives you a written red-flag review so you can ask the right questions before you sign or pay a deposit.

What gets compared
A cheap bid can be cheap because it left work out.
| Review area | Why it changes the price | Question you can ask |
|---|---|---|
| Scope detail | Broad wording can hide labor, prep, cleanup, finish level, quantities, and room-specific work. | What exactly is included in each line item? |
| Allowances | Low placeholder budgets make one quote look cheaper until selections, tax, freight, markup, or install costs arrive. | Does this allowance cover the full installed cost? |
| Exclusions | Permits, code upgrades, hidden conditions, patching, hauling, and cleanup may be pushed outside the number. | Which common costs are not in this bid? |
| Payment timing | Two similar prices carry different risk if one asks for more money before visible work is complete. | What work is complete before each payment is due? |
| Change orders | Missing rules for written approval, markup, labor rates, and delays can turn unknowns into budget surprises. | How are changes priced and approved before work continues? |
How it works
A controlled review workflow, not a magic answer.
Start the review through Stripe.
Checkout captures the review tier and routes you to the upload page with the same email.
Upload the quote, contract, scope, and notes.
The review is grounded in the documents you provide. Missing information gets called out instead of guessed.
Use the questions before you sign.
You get risk notes and questions by email. The review does not choose a contractor or guarantee project outcome.
Decision guardrails
What the review will and will not do.
- Plain-English red flags in the quote language
- Questions to clarify before signing
- Missing-document notes if the bid is not reviewable enough
- Source-grounded observations based on the materials you send
- Contractor recommendation or vetting
- Legal, financial, engineering, inspection, or construction advice
- Cost guarantee or project outcome guarantee
- On-site inspection or live negotiation support
Educational review only. You remain responsible for decisions, contractor selection, legal review, inspections, and project outcome.

Common questions
FAQ before you compare contractor bids.
Why are remodel bids for the same project so different?
Usually because the bids do not include the same scope, allowances, exclusions, payment timing, change-order rules, or risk assumptions. The lowest total may be missing work that another contractor included.
Should I choose the cheapest contractor bid?
Do not choose based on price alone. First compare what each bid includes, what it excludes, how realistic the allowances are, when payments are due, and how changes are approved.
What do I send for a Bid Before Build review?
Send the contractor quote, contract or proposal, scope notes, allowances, exclusions, payment schedule, plans, selections, and any messages that explain what is included. Missing information is flagged instead of guessed.
Does Bid Before Build choose the contractor for me?
No. The review does not recommend or vet contractors. It gives written red-flag notes and clarification questions so you can make a more informed decision.
Is the review legal, inspection, or construction advice?
No. The review is educational and based on the materials you send. It is not legal, financial, engineering, inspection, construction, contractor-vetting, or project outcome advice.
