A Message from C J Krzywonski - March 24, 2020

We all know this is an unprecedented time in our history and although the Great Depression started and ended before i was born, I heard plenty of stories from Mom, Dad, Aunts, Uncles and Grandparents who worked and lived through it all as they farmed the land and scratched out a living. This COVID-19 Pandemic is having a tremendous impact on the health of the elderly and many of the businesses we rely on every day. When you don't have much, and you're simply a very small business concern - the health of the global economy is something you just don't pay much attention to as you try to live day to day. As we all strive to figure all this out, and navigate through these days and times - I want you to know that when it comes to window and door parts - WE'RE HERE FOR YOU!
