Questions to Ask a Contractor Before Accepting a Quote

How Do I Describe My Job Before Asking for Quotes?

Describe what you want to change, where the work is needed, and the details you already know. Include measurements, photos, access limits, and materials you prefer when available. Keep unknown details as questions for the contractor instead of guessing.

Before You Book an Estimate

Ask whether the estimate has a fee before scheduling the visit, even if you decide not to hire the contractor. Oklahoma's Construction Industries Board includes this check in its homeowner guidance.Source: Oklahoma CIB: estimate fees and contractor checks

1. 1."Do you charge for the estimate if I hire someone else? Please confirm the amount and what it covers before the visit."

Start With the Written Work Description

The FTC recommends multiple written estimates and an explanation of large price differences. The estimate should describe the work, materials, completion date, and price. Check applicable licensing and insurance before hiring.Source: FTC: choosing a contractor and checking written estimates

What Should a Written Contractor Quote Include?

Which Questions Should I Ask Before Accepting the Quote?

1. 1."Can you list the exact work and quantities this total covers?"
2. 2."Which materials or equipment will you install? Please include model numbers or product grades."
3. 3."What is excluded? Does the total include permits, removal, disposal, cleanup, and applicable taxes?"
4. 4."Which amounts are fixed, which are allowances, and which depend on conditions you cannot see yet?"
5. 5."If you find extra work, will you show the issue and give me a written price and schedule change before proceeding?"
6. 6."Will you use employees or subcontractors, and who will supervise the work and be my contact?"
7. 7."Can you provide proof of current insurance and any credentials required for this work, so I can verify them?"
8. 8."What payment is due at each milestone, and what work does that milestone represent?"
9. 9."What work must be complete, and when can we review it together, before final payment is due?"
10. 10."What is the start window, expected duration, and plan if materials or inspections cause a delay?"
11. 11."What do the material and labor warranties cover, and who handles a claim?"

Ask whether employees or subcontractors will perform the work and name your main contact. NAR's remodeling guide recommends these questions and verification of active insurance. Check any required credentials with the issuing authority; requirements depend on the work and location.Source: NAR: crews, communication, and insurance checks

Agree in writing on the work and final review that precede final payment. The FTC advises against full payment upfront and recommends final payment after the work is complete and you are satisfied. Ask how any unfinished items will be resolved.Source: FTC: payment and completion guidance

For Work in Oklahoma

Oklahoma's Construction Industries Board advises checking current roofing registration and current licenses for electrical, plumbing, and mechanical contractors. Check the credential that applies to the work. A current credential does not guarantee work quality.Source: Oklahoma CIB: current credentials and their limits

1. 1."What is your applicable license or registration number, and where can I verify that it is current?"

How Do I Ask the Contractor to Clarify the Quote?

"Thank you for the estimate. Before I decide, please confirm the work and quantities, product details, exclusions, permits, cleanup, payment milestones, warranty, and change-order process. Please put any changes in the written estimate so I can compare the same scope."

What If the Contractor Will Not Explain an Item?

Keep the missing answer visible in your comparison. Do not treat a blank field as included work. If the contractor cannot define the work or change process, obtain another written estimate before deciding.

Does a Checklist Replace the Contractor's Estimate?

No. A checklist helps you prepare the conversation and track answers. Ask the contractor to inspect the job, confirm which tasks apply, and provide the price and terms in writing. Keep their written estimate and any agreed changes with your checklist.
