What should I ask a concrete patio contractor before hiring?

Before hiring a concrete patio contractor, verify their license and insurance, get at least 3 written itemized bids, confirm they will pull all required permits in their name, review the contract for a milestone-based payment schedule, and ask project-specific questions about materials and installation method. Never pay more than 30% upfront.

How many contractor quotes should I get?

You should get at least 3 written, itemized quotes before hiring a contractor. This gives you enough comparison points to identify a fair price range and spot any outliers. Always ask for the same scope of work across all bids so you're comparing apples to apples.

What is a red flag when hiring a contractor?

Major red flags include: asking for more than 30% upfront, asking you to pull permits in your name instead of theirs, no physical address or license number, pressure to sign immediately, no written contract, and quotes that are dramatically lower than all others (often a sign of cut corners or hidden costs).
