The lowest number doesn't always describe the same work.

Scope

The most important comparison. Two quotes for the “same” project can describe different work. List what each quote says it covers, and notice what it never mentions — silence is not the same as included.

Materials

Does the quote name specific products and models, or just categories? “Grab bar” can mean a $15 store bar or a $90 professional-grade one. Unnamed materials are a question to ask.

Allowances

An allowance is a budget placeholder — not a fixed price. A quote with a $800 fixture allowance can grow the moment you pick real fixtures. Mark allowances so they're never mistaken for final prices.

Exclusions

What does the quote say it does NOT include? Painting? Patching? Permits? Exclusions tell you what will show up later as an extra cost — or another contractor's job entirely.

Permits

Many home modification projects require a permit, and the rules depend on your city and county. If a quote doesn't say who determines and obtains permits, that's a question to clarify — not a detail to assume away.

Cleanup & disposal

Removing and disposing of old materials costs money and (in many places) has rules about what can go in the trash. If a quote never mentions disposal, ask whether it's in the price.

Payment schedule

Compare deposits and payment timing, not just totals. A large deposit before work begins is worth thinking about carefully. Consumer guidance generally favors paying in stages tied to work completed.

Change orders

What happens when the scope changes mid-project — and how is a change priced before it becomes part of the agreement? A quote that doesn't say is telling you something.

Warranties

Labor warranty, material warranty — who stands behind what, and for how long? If the warranty isn't written in the quote, ask for it in writing before you decide.
