Local Pittsburgh Window Installation Specialists You Can Trust
Celebrating Our 47th Anniversary

Your partner for smarter historic restorations

For four generations, Marvin has built a reputation for doing the tough window replacement projects. We collaborate early on with architects, facilities managers and general contractors; review products and options; navigate the National Parks Service guidelines; discuss window specifications with local historic commissions; and attend field testing. We offer the best project-based solutions and work with all participants to achieve excellent performance and historical accuracy.


At every step, we bring an unmatched level of expertise, with service tailored to the needs of your historic project. 

Architectural Project Managers

Marvin’s architectural project managers (APMs) have strong relationships with historic field professionals and a deep knowledge of historic buildings, providing an ideal support system for window and door projects.
