13 questions to ask any contractor before you sign anything. After 15+ years and 700+ projects across greater Los Angeles, these are the questions that separate trustworthy contractors from ones who will cost you more in the long run.
0 of 13 checked
Are you licensed with the California Contractors State License Board (CSLB)?
Ask for their license number and verify it at cslb.ca.gov. Any contractor doing work over $500 in CA must be licensed. If they hesitate, walk away.
Do you carry general liability and workers' compensation insurance?
Ask for a certificate of insurance naming you as an additional insured. Without this, you're liable if a worker is injured on your property.
Are you bonded?
A contractor's bond protects you if they fail to complete the job or cause damage. It's a sign they're operating a legitimate, accountable business.
Will you provide a detailed written estimate with itemized costs?
Vague quotes like "around $15k" lead to disputes. You want line-by-line: materials, labor, demolition, cleanup. Never accept a verbal-only quote.
Do you use a written contract that outlines the full scope of work, timeline, and payment schedule?
A solid contract protects both parties. It should include start/end dates, what's included, what's excluded, and what happens if something changes mid-project.
What is your payment schedule — and do you require a large deposit upfront?
California law limits deposits to 10% or $1,000 (whichever is less) for most residential projects. A contractor demanding 50% upfront is a major red flag.
Will you pull all required permits for this project?
Unpermitted work can stop a future home sale, void homeowner's insurance, and cost you more to fix later. The contractor — not you — should handle permits.
What is the realistic start date and estimated completion date?
Get it in writing. Ask what happens if they go over schedule — are there penalties? Also ask how many other projects they're running simultaneously.
What specific materials and brands will you use — and can I see samples?
Low bids often mean low-grade materials. Ask for the exact product names so you can compare. Reputable contractors are proud to share this information.
Do you offer a workmanship warranty — and what exactly does it cover?
A reputable contractor stands behind their work. Ask for the warranty in writing. Watch out for vague "we'll come back if something's wrong" promises with no timeframe.
Will you be using subcontractors — and are they licensed and insured too?
Many contractors sub out work to unlicensed crews. Ask who specifically will be on your property each day, and confirm they're covered under the contractor's insurance.
Can you provide 2–3 recent references from similar projects in my area?
Call the references. Ask: Did they finish on time? On budget? Would you hire them again? A contractor who hesitates to provide references is hiding something.
Do you have verifiable reviews on Yelp or Google — and can I see photos of completed work?
Look for consistent 5-star ratings with specific details (not just "great job!"). Check that photos show real projects similar to yours — not stock images.
