West Columbia SC Contractor License Verification: A Homeowner’s Checklist

When you are planning window or door work, the first thing to check is not the color sample or the estimate, it is whether the contractor is properly licensed and set up to do the job.

Start with the license itself. A real contractor should be able to give you a license number, the business name it is registered under, and the type of work it covers.

Price matters, but it should not be the first filter.

If one quote is far below the others, ask what got removed from the scope.
