  • Awning windows – Hinged at the top to swing outward, awning windows are typically used in first-floor bathrooms and basements.
  • Bay windows – These windows protrude from your home, giving it a unique look from the exterior and giving you more room inside.

  • Casement windows – Casement windows have a side hinge, allowing the window to swing in the same manner as a door opens and closes.

Envision Your New Windows

We went with Zen Windows 2 years ago to replace the original wooden windows in our 1950’s home. Not only was the process super simple from quote to instalation, 2 years later and they still stand by their work and warranty. We discovered an issue with the window in our bathroom and the team was very quick to respond and remedy. I was very glad to know that even though time had passed, they still stood by the quality of their work and wanted to ensure I was 100% satisfied! Great value, professional team and I would recommend them!
