✨ One of our favorite transformations lately – completed in Wilton, CT.

This home already had beautiful architecture, but the old windows and doors were starting to feel outdated and inefficient. The homeowners wanted to keep the character of the house while upgrading comfort, energy efficiency, and natural light – and that’s exactly what we did.

🔨 Our team installed brand-new OKNA energy-efficient windows and doors, including:
• Large picture windows
• Elegant arched specialty windows
• Modern window walls
• New glass patio doors

The new OKNA windows completely refreshed the home while improving insulation, reducing drafts, and bringing in so much more natural light. One of the biggest transformations was the stunning arched window area – now it looks brighter, cleaner, and far more modern without losing the home’s original charm✨

✔️ Better energy efficiency
✔️ More natural light
✔️ Clean modern look
✔️ Premium OKNA window performance

Swipe through the before, in-process, and after photos – the difference speaks for itself.
