A useful contractor bid tells you what you are buying, what you still need to decide, and what could change the final bill. Before comparing totals, put each proposal against the same project description. Then check the materials, exclusions, allowances, payment milestones, timing, and process for approving extra work. If a line is unclear, ask for a revised written proposal before choosing a contractor.

Start with one project brief

Give every bidder the same information. For a bathroom remodel, that might mean keeping the current layout, replacing the tub with a shower, installing a specified vanity, and replacing the floor. Include photographs and measurements where available, but let the contractor inspect conditions that affect the work.

Separate decisions you have made from decisions you have not. “Install tile” leaves a lot open. “Install the selected porcelain floor tile in the existing bathroom footprint, including the agreed preparation and removal work” gives the contractor something more specific to price. Ask each bidder to identify anything they cannot determine until they inspect the site or open an existing wall.

Use this bid comparison worksheet

Copy these rows into a document and add one column per contractor. Write “unconfirmed” rather than leaving a blank cell. A blank looks easy to overlook; an unconfirmed item gives you a question to resolve.

Separate fixed selections from allowances

An allowance is a budget for something that has not been fully selected or priced. A fixture allowance might cover the product alone, or it might also cover delivery, tax and installation. Those are different offers.

NARI's remodeling glossary explains allowances and change orders and recommends comparing bids with matching scope and quality. Use the proposal to establish how the allowance works on your project.

Ask what happens if your selection costs less or more than the allowance. Will the difference be credited? Does a markup apply? Could a different selection require extra installation work? Record the answers before using that amount in your comparison.

Look for exclusions before judging the total

Exclusions are not automatically a warning sign. They become a problem when nobody notices them until work starts. Common questions to resolve include debris removal, disposal fees, painting after repairs, delivery, appliance connections, and repairs to adjacent surfaces.

Compare complete scope, not guessed final prices

Here is a hypothetical example to show the method. These figures are made up for illustration and are not market prices.

Bid A is $18,000 and excludes disposal and painting. Bid B is $20,000 and includes both. You cannot conclude that Bid A saves $2,000 until you know what those missing tasks will cost and who will arrange them. Ask Bid A's contractor to price the same agreed scope, or obtain written quotes for the excluded work.

The FTC's home improvement guidance recommends multiple written estimates and asking why prices differ. A low price needs an explanation you can check, just as a higher price does.

Verify permits, credentials and insurance locally

Ask the building department whether your planned work requires permits and inspections. The proposal should identify who handles them and whether fees are included. If a contractor says a permit is unnecessary, check the answer with the authority before relying on it.

The FTC advises checking licensing with state or county government and requesting proof of insurance. These checks belong before a contract decision, not after a deposit.

Review payment milestones and changes together

Write down when each payment is due and what work or delivery triggers it. Ask how you will confirm that milestone has been reached. Do not assume a particular deposit percentage is legal everywhere; check your state or local consumer protection rules.

A change process should explain how proposed extra work is described, priced and approved, including any schedule effect. Keep the approved document with your original agreement. A casual conversation can leave the homeowner and contractor with different expectations.

For a jurisdiction-specific example, California's Contractors State License Board explains written change orders and contract responsibilities for California home improvement work. Its requirements should not be treated as the law in other states. Use the relevant local authority for your property.

Send a clear clarification request

You can use this message before making your decision:

“Thank you for the proposal. I am comparing bids against the same project brief. Please confirm the included materials, allowances and exclusions; permit and inspection responsibilities; payment milestones; estimated start and completion conditions; and the written process for approving changes. Please also identify any work you cannot price until further inspection. I would appreciate an updated written proposal reflecting these answers.”

Your next step

Prepare your project brief and comparison worksheet first. Browse our home improvement services to organize the work, then use the contractor-options link on the LocalContractorBids homepage if you want to continue to The Builder Market. Independently verify each contractor and read the final agreement before signing.
