🔨 FACT FRIDAY

Did you know the word “carpenter” originally had nothing to do with building houses?

The word comes from the Latin carpentarius, meaning “wagon maker”
So, before carpenters built houses they built wagons and two wheeled carriages! 👀

Proudly Canadian. Proudly Independent.

For more than six decades, your Castle Building Centres have been helping Canadians build, renovate, and improve the places they call home. From coast to coast, our independently owned retail locations are deeply rooted in the communities they serve.

As a Canadian company, we’re proud to support local businesses, Canadian families, and the local economies that help our communities thrive. At Castle we are building more than homes and projects, we are Building Communities!
