What Makes a Window Contractor MHIC Licensed in Maryland?

If you are replacing windows in Maryland, the license matters as much as the product on the truck. A contractor can sound polished, quote a fair price, and still be operating outside the rules if they are not properly licensed with the Maryland Home Improvement Commission, or MHIC.

The work affects flashing, insulation, moisture control, energy efficiency, and, in older houses, historic details and permit issues.
