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.

  • Impact and Cycling
  • Acoustic Materials and Product Construction
  • NFRC Thermal Certification
  • Condensation Resistance Factor Simulation
  • Validation Testing
  • STC and OITC Testing
  • HUD Approval
  • AAMA/WDMA/CSA 101/I.S.2/A440-05
  • Machine in Londonderry, NH Testing Harvey Windows

Who We Are

We may sell replacement windows, doors, and other quality building materials & products for the exterior of your house, but that’s not what our customers are buying. They’re buying the peace of mind that comes from working with a company that stands behind every product, every day. So you aren’t just installing windows or siding or shingles. You’re installing confidence.
