Questions about the company

Ask who you are contracting with, how long the company has performed this type of work, who will perform and supervise the job, and what licensing or registration applies locally.

Questions about the proposal

Ask what is included, what is excluded, what assumptions were made, what could change the price, and whether permits or inspections are required.

Questions about execution

Ask when work could begin, how long it may take, how your property will be protected, who your contact is, and how unexpected conditions are handled.

Questions about protection

Ask for applicable insurance information, written warranty terms, manufacturer documentation where relevant, payment schedule and closeout paperwork.

The best question: why?

When contractors recommend different solutions, ask each to explain why. Understanding the reasoning can be more useful than comparing totals alone.
