A historic home gets a modern update 🏡✨

One of the biggest milestones in Diane & Ken's 100-year-old Huntington home restoration is complete!

After being fully demoed and wrapped in Window World house wrap, this historic home is now seeing its next chapter take shape with custom-designed windows that complement its original architecture.

The goal wasn’t simply to replace old windows. Every detail was selected to preserve the character of the home while bringing in the comfort, efficiency, and performance of modern windows.

And this is only the outside. We can’t wait to see the finished transformation!
