State-of-the-Art Manufacturing

                                          Harvey’s manufacturing facilities are located right here in the United States, where we put our more than 50 years of experience to use crafting custom made windows, front doors, and porch enclosures that add strength, value and beauty to every home in which they’re used.

                                          And we don’t just make windows and doors products beautiful, we make them to last. As a local Northeast company, we’re well aware of the beating exterior building products can take. So we built our own in-house testing lab where we consistently take windows, doors, and enclosure systems off our production lines and test?their performance.

                                          Our lab performs the following?tests to verify thermal and structural requirements, to ensure that our products meet our high standards of quality and durability.
