Two Fish Window Cleaning Employees Cleaning Claymont Steak Shop's Windows


Giving to Our Community

In honor of Random Acts of Kindness Day in February and to help spread some positivity, we donate a free window cleaning to help local businesses in our community! 

In 2022, we chose Claymont Steak Shop and Bing's Bake & Brew because we know they're local favorites and, like many other local restaurants, have seen their share of struggles during the pandemic. 

In 2023, we chose Sean's House / Unlocke the Light
. This incredible foundation makes a huge impact on our community every day.

Our goal is to help make lives a little brighter. It's our absolute pleasure giving back to our community!
