About the company
How long have they worked in the St. Louis area? Who will actually do the work, employees or subcontractors? Can they share photos of similar jobs?
A straightforward contractor is happy to answer.
About the work
What does the process look like from start to finish? How are surprises such as rot or old wiring handled? What is the expected timeline and what can delay it?
Ask what prep and cleanup are included.
About paperwork
Ask about licensing and insurance appropriate to the work, and about permits. Licensed, insured contractors can usually provide proof when you ask.
Get the estimate, scope and payment terms in writing before work begins.
About the finish
How will they communicate day to day? What happens if you are not happy with a detail? What warranties come from the contractor or the manufacturer?
A good contractor welcomes these questions because it prevents misunderstandings.
