a written policy to evidence its existence and a compliance
affidavit listing the testing lab and random testing

comp carrier documenting their experience mod ratio.

production schedules and job site safety plans, and
keeps you informed of progress.

and in a timely manner.
- Require a letter from the carrier stating their ability
to bond along with their bond rating.
What do previous customers think? Most good contractors
ask their customers to help them rate their projects.
Ask the contractor to provide:
- Proof of a documented policy for collection of post
project customer satisfaction including results generated.

as in your geographic area.
- References of a similar scope completed 3, 5, and
7 years ago so that the customer can review their record
and warranty follow up.
