Concrete Block in Pittsfield, MA

Concrete block is one of the most useful and versatile building material around. Even the ancient Romans used it! The uses are endless: foundations, fireplaces, raised garden beds, steps, pavement for patios and walkways, shelves, under sheds and decks to keep the varmints out... you can even use them for boat ballast or to keep your truck's rear tires from spinning in the snow!

We're proud to have been making our own block at Johns Building Supply for almost 70 years in Pittsfield, MA. Our block is known for its exceptional quality. Every block we make meets the high standards of the American Society of Testing and Materials. We believe that you won't find better block at a fairer price anywhere.
