You will need to make sure that your concrete contractor is licensed to work in your state. This is even true if you're only hiring a contractor to do concrete floor staining. This added level of licensing protects you if you happen to hire a contractor that can't live up to his or her word. If the job is sub-par or perhaps can be found damaging, then you will have more recourse against a licensed contractor.

Remember to always get an estimate on any floor staining work you need done. The cost of concrete staining can be highly variable. You want to be sure that you know what to financially expect before you actually hire someone. You may also want to consider getting a few different estimates from other contractors. This will provide you with the greatest potential for finding the best price.

Try to only work with contractors that you can find references for. These references can either be local or by way of online reviews. Either way, you want to be able to learn about the contractor before you give him or her money. These references and reviews will give you an in-depth perspective on the contractor before you spend any money.
