What Makes a Window Contractor MHIC Licensed in Maryland?
For Maryland homeowners, the license is part of the job, not an optional extra. A contractor who replaces windows without MHIC registration is taking on work that should be done under Maryland's home improvement licensing rules. A window job can look simple from the street, but the details matter. If the installer misses flashing, compresses insulation badly, or ignores historic requirements, the consequences usually show up later as drafts, rot, or inspection problems.
