Parts & Field Service


For your convenience, we keep a selection of parts in stock, and can order most other parts that may be needed.  In most cases, we can even order parts for older Marvin windows or doors that are obsolete or are past warranty.   It's best to register your Marvin products within 90 days of installation.  Find out more at

Field Service

Our Service Department is dedicated to ensure the performance of products purchased at Woodbury Supply and Millwork Masters. We train continuously to provide you with Marvin’s 

latest innovations and installation techniques.  

After installation, our Marvin-trained professional service technician will take care of any issues you may have. Our exceptional service not only gives our customers the highest level of service possible, it sets us apart from our peers. We stand behind the work we do.  That’s why so many of our customers, both homeowners and professionals, come back, and also recommend us to others.
