Types of Replacement Windows

Naturally Durable and Energy Efficient

Vinyl Windows

The inherent insulating properties of vinyl window frames help to curb heat transfer and improve thermal performance. Plus, vinyl windows are easy to clean, and they never need to be painted.

Superior Resistance to Weathering

Fiberglass Windows

When it comes to lasting durability, it’s hard to beat fiberglass windows. The extra-strong fiberglass material of these windows dutifully resists damage from moisture and impacts for decades.

John and his team at Green City were beyond helpful with our window replacement. They gave us a time frame after ordering the window and surprised us with a call before we expected. They were out the following morning to install the window with no issues; couldn't even tell they were there. I would definitely recommend them.

- Zach D.

I recently contracted with Green City to provide and install 17 windows, 2 Sliding Glass Doors, Full House Siding replacement, new gutters and downspouts, and 3 decks. It is a huge project. John and his team did an excellent job, were very professional and friendly. John was always responsive and provided great detail and information on all my questions. I always felt that John and his team kept my best interests in mind. I would definitely use their services again.

- Karen J.

We've used John's crew before for window replacement so there was never a doubt who to call when we needed more done. As before, Green City came through admirably. We'd recommend them to anyone and will certainly call John again should we need more work done!
