Finish and protection

- Cleanup, lawn or landscape restoration, and final inspection.

Keep the decision documented.
Use the written proposal and approved change orders—not verbal assumptions—as the project record.
Frequently asked questions
How many concrete bids should I get?
Enough to understand the market and compare scope. Three is common, but the quality and completeness of each proposal matter more than a fixed number.
What if a contractor will not put the scope in writing?
That makes price comparison and later accountability difficult. Ask for a written proposal before authorizing work or payment.
