My biggest concern is the type of people that will be coming into my home.
Make sure their licensed and insured. A good reputation doesn’t hurt either.
The main concern is that they are licensed, bonded and have insurance for the type of contracting they do.
Also, hiring a contractor that has reviews, references or work you can go look at, is a good idea.
Licensed, insured and experience. Many new contractors with little experienced. Look for references.
