Yesterday we joined the Quad Cities Chamber of Commerce for Business After Hours at Iron Tee in Bettendorf. There were snacks, drinks, a closest-to-the-pin contest, and plenty of great conversation.

We loved catching up with familiar faces and meeting some new ones. Thanks for hosting us!

Details like this are what make a window feel finished. Take a look at this EverWood® sill for example. The finish is rich, the lines are crisp, and every piece is built to look good for years. Plus, every EverWood® interior is custom stained to match the wood trim already in your home.

Stop in and see for yourself at 915 Middle Road in Bettendorf.
