A change order is a written, signed agreement that changes the scope, price or schedule after the contract is signed. Changes are normal - hidden rot, a code requirement, or you choosing a different tile. What matters is that each one is written down, priced and approved before the work is done. California, for example, requires changes to a home improvement contract to be in writing and signed; many states have similar rules.
A good change order includes
How to handle a change, step by step
Stop and ask for photos or a look at the problem.
Ask for the change in writing with a price.
Compare against unit prices in your contract.
Sign only when you agree; keep a copy.
Track the running total of changes vs. your contingency.
Keeping changes under control
Make selections before work starts
Put realistic allowances in the contract
Keep a contingency (many homeowners set aside money for surprises - older homes usually need more)
Avoid verbal 'while you're here' requests
Ask for unit prices for likely unknowns (decking, rot, rock) in the original bid
