We’re Building Success Every Day with Experience and Vision

MAPG has been providing quality glazing services for over 60 years. Currently in our third generation of family ownership, the company that once survived on providing stained glass windows for churches has grown to be an industry leader with a diverse array of projects including:

Based in Johnstown, PA, we work on projects of various sizes and complexity, typically within the Mid-Atlantic Region. For the past ten years, we’ve completed projects in the Baltimore, D.C. Metro and surrounding areas with quality service and craftsmanship. Our Pennsylvania location allows us to provide competitive prices and close proximity to Baltimore, D.C. and Virginia. Most recently, we’ve expanded our project reach to the South and Northeast.
