You’ve interviewed three contractors for your project, and the bids have arrived. One is a single page with a final price. Another is a twenty-page detailed document. The third is somewhere in between, but the price is 30% lower than the others.

How do you compare apples to apples?

Choosing a contractor based solely on the lowest bottom line is the single biggest mistake a homeowner can make. A vague, low bid is often a Trojan horse for massive mid-project cost overruns. Here is a guide to understanding what a professional, transparent construction estimate should look like.

The Danger of the “Napkin Quote”

If a contractor gives you a quote that just says “Bathroom Remodel: $15,000,” run away. This lacks “Scope of Work.” It doesn’t define what materials are being used, what is included, and more importantly, what is excluded. You have no protection when they later claim that painting the walls wasn’t included in that price.

Key Components of a Professional Estimate

  • Detailed Scope of Work (SOW) The estimate should break the project down phase by phase (e.g., Demolition, Framing, Electrical, Plumbing). Each section should describe exactly what will be done.
  • Labor vs. Materials While not every contractor breaks these out exactly, you should have a clear sense of what is being built versus what is being bought.

The “Allowances” Trap

This is where bids become confusing. An allowance is a placeholder budget for items you haven’t selected yet.

  • Example: A contractor includes a $2,000 allowance for kitchen appliances. You later realize the fridge and stove you want cost $5,000. You are instantly $3,000 over budget.
  • The Fix: Ensure allowances are realistic for the quality level you expect. Ask the contractor what those allowances are based on.

Exclusions

A good estimate explicitly states what they are NOT doing. Are they handling permit fees? Who pays for dumpster rental? Are final cleaning services included?

Red Flags to Watch For

  • Requiring huge deposits upfront: Be wary of contractors asking for more than 10-20% down before materials are ordered.
  • No proof of insurance or licensing included with the bid package.
  • Bids that are significantly lower than others: If two bids are $50k and one is $30k, the low bidder is likely missing something massive in the scope of work, or planning to use sub-par materials.
